6 common projector problems after installing a new lamp

Problems after installing your new projector lamps? Here are some solutions.

Sometimes things don’t go as planned after installing a new projector lamp. Here  are the solutions to the six most common projector problems.

Problem #1: My projector won’t turn on after I’ve installed my new lamp.

Solution: Check the power cord, lamp cover and lamp connections.

Before contacting customer service, be sure to first check that the projector power cord is plugged in and properly secured. Check the back lamp cover – if it’s loose the projector won’t turn on.  If this doesn’t solve the problem, then open up the lamp cover and check the lamp connections. If the screws are too loose or too tight, the projector will not turn on.

Problem #2: My projector is getting too hot after replacing the lamp

Solution: Clean your air filters and ventilation holes.

The main reason a projector starts to heat up is because the air filters or ventilation holes are clogged with dust or other debris. DLP projectors operate at high heat and most have one or more fans that blow air around the components to cool them off. A build up of dust prevents proper air circulation and can cause the projector to become very hot and the lamp to explode. When this happens, the projector temperature controls will go off. Always clean your filters after replacing the projector lamp. Use a can of compressed air and blow filters and ventilation holes dust free.

Problem #3: The picture is fine but there is onscreen message says to replace the lamp even though it’s new!

Solution: You need to reset the lamp timer.

Your projector has a Lamp Timer or Lamp Hour Counter that automatically tracks lamp usage. It’s been designed to send you warning messages on screen and to trigger the Lamp Indicator when the projector lamp is approaching end of life. Many projectors will turn off automatically when the end of lamp hours has been reached – whether the lamp is new or not. Always reset your lamp timer after replacing the lamp. Check out our lamp replacements guides or your projector manual for instructions.

Problem #4: The picture is much dimmer.

Solution: Re-install the new bulb or replace the generic lamp previously installed.

This problem usually only happens when you have replaced only the bulb and not the entire housing. Check to make sure the bulb has been installed correctly. Purchasing a bare bulb is an economical option but you have to make sure it’s been installed properly. It should be flush with the front of the lamp housing cage and the new bulb should sit exactly in the same placement as the old bulb. If the new bulb is off center or not aligned properly your image will be dim. Removing the bulb and re-installing it more carefully should take care of a dim picture.

Problem #5: Projector turns on for a minute and then shuts off.

Solution: Recheck the lamp timer. Check the fans and filters. Replace the generic lamp.

Sometimes the lamp timers need to be reset twice. Every time you open up the projector, you need to check the lamp timer is set to zero. Projectors will turn themselves off automatically if they detect any problems. You may also need to clean out all dust from from the projector to make all components work together in harmony. If dust is not the problem, then it’s the actual lamp. Have you installed a genuine OEM projector lamp? Generic, compatible lamps don’t operate properly in most projectors causing them to out of balance. This will make the projector shut down automatically. The solution for this problem is to replace the generic lamp with a genuine OEM lamp.

Problem #6: The screen color is wrong and the picture is flickering.

Solution: Your color wheel may need to be replaced.

Faded onscreen color is one of the first indications that the lamp is reaching end of life. If you have installed an OEM lamp without any issues then the problem may be the color wheel. If your lamp has exploded or melted inside the projector, there is a very good chance the color wheel was damaged. Also installing generic lamps can damage the sophisticated and sensitive components such as the color wheel and DLP chip. The only solution for this problem is to contact a service rep and replace the color wheel.

  • I installed a new lamp and after some one month there was dark spots at the bottom left of the screen then more and more untill it engulfs the entire projection. What is the solution to this?

    • Hi Xavier,
      It sounds like a lamp failure. Was this a generic lamp or original OEM? It may have broken the colour wheel. I suggest joining our forum to ask advice from our experts.

      • Hey I have 65 inch sharp dlp projection tv it’s shows from a light that has power but when I push that power button light goes off and never comes back on so tv doesn’t on a all frustrating

        • Hi Sam,
          You have reached end of lamp life and the projector is switching itself off to protect itself from an old lamp past its prime. How old is the lamp and when was the last time you changed it? That is usually the main reason for the TV not turning on.

          Shelagh McNally October 23, 2017 2:37 pm Reply
    • I believe it has more to do with the color filters. It gives me the impression that the new lamp provides a much hotter light beam and it has burned the color filter, another possibility is the dust buildup on the filters themselves.

      Jorge De Roux December 14, 2018 1:31 pm Reply
      • Hi Jorge,
        It’s the color wheel and ballast that control the color. There may be a problem with this but it would be from the lamp exploding. The projector will self preserve and shut down if the heat becomes too much. There may very well be a problem with the lamp being too hot ifit’s a counterfeit lamp.
        Thanks for your input!

    • The problem is not the lamp. It’s probably the DMD chip

      Air September 30, 2019 12:21 am Reply
    • It sounds like your DMD chip is failing. Lamps will not cause “spots”. If it is a DLP projector and started out looking like pepper in the corner, and then like there was more and more pepper on the screen, the Digital Micro Mirror Device (DMD chip for short)has likely gone bad.
      This chip will generally run a couple hundred bucks, and you can usually get them on Amazon and eBay. Make sure you get the exact correct one for your projector, or an updated version that replaces the chip you have. It takes a fair amount of skill and confidence to replace that chip. I would suggest getting some thermal pads with it as the ones on the current chip likely need to be replaced. Ask whomever your order the chip from if they have pads available as well.

  • I just installed a new lamp in my Mitsubishi XD490U, the picture is still not working. There is power but the lamp does not light up. What can I do?

    Eldon Floyd October 22, 2015 8:37 pm Reply
    • Hi Eldon,
      How is the picture not working? If you have a picture with colour that is off, it may be the colour wheel. If the screen is still dark, it may be the projector not registering the newly installed lamp. Did you reset the lamp timer after installation. Please send us more information and we will try to solve the problem.

        • Hi Matt,
          Check all your connecting cords and cables to make sure nothing has become loose. You can also:
          Press the Source button on the projector repeatedly to cycle through the available sources.
          Wait a few seconds for an image to appear.
          Turn on the connected computer or video source, and press its play button to begin your presentation, if necessary.
          Hope this helps.

    • Hi Dimitris,
      How old is the lamp? It sounds like the lamp has failed and needs to be replaced. You need to check the lamp timer and see if there are any warnings showing up. Here is a link to the manual: http://www.projectorcentral.com/pdf/projector_manual_6108.pdf
      It will show you how to find the lamp timer information and the warnings associated with the end of lamp life.
      Hope this helps.

    • It sounds to me like the projector may have overheated enough to glitch the main board. Considering the region you live in, the interior of your projector is likely very dusty.
      I would recommend as a first step disassembling the case and using compressed air to blow out all the fans and ducts, and if it has a filter, clean that. Lamps generally do not cause a projector to freeze or make a PIP window get stuck.
      If it has a colour wheel (DLP), make sure it moves freely. They can cause flickering if they go bad, and if they stop or run too slow the projector can detect that and shut off.

  • I have a benq w1070. Replaced the lamp and when turning on the power button turns green and after a few seconds the word lamp turns red. No light coming out of the lense. Second bulb I have tried.

    Art May 18, 2016 4:47 pm Reply
    • Hi Art,
      Did you rest the lamp timer? Unless you reset it back to zero the projector will assume the lamp has reached end of life and still needs a new lamp. The projector will turn itself off automatically to prevent it the old lamp being used. Have you consulted the BenW1070 manual for the exact instructions on how to reset the lamp timer? You can find it here: http://www.manualslib.com/manual/422315/Benq-W1070.html

      • if the projector automatically turns off because it thinks the lamp has reached its end life, how can you reset the timer? Doesn’t the lamp need to be on so you can see the menu to reset the timer?

        Joe October 13, 2016 3:36 pm Reply
        • Hi Joe,
          You can usually see the reset menu using the remote control. It depends on what type of model you have. On many you can use the menu bar and scroll down to the function associated with the lamp timer. If you let us know what type of projector you have, I can send you specific reset instructions.

          • Ok, I had the same thing happening to me, I reset the timer and it was ok for a few minutes but then it did the same thing only it didn’t snap out of the green/purple

            Callum March 22, 2018 10:45 am
          • Hi Callum,
            Probable cause is most likely the discoloration either dirty polarizers, or the polarizing array slightly out of alignment. You could also check the VGA cable if that is worn out it gives your that green/purple problem. Also, is the replacement lamp authentic? If it’s a knock off then it’s out of alignmet and should be replaced with a lam calibrated to work with your projector.

  • My projectors (infocus x10) lamp light went on after I gave it a good cleaning. I bought a new lamp and the light is still on. Looking at the old lamp I can’t see any obvious marks of wear or damage. Looks identical to the new one. Is there any logical explanation for this? I opened it up to see if anything was loose, but everything looks okay.

    • Hi Ken,
      The lamp may have been damaged when you removed it to clean it. How long was the lamp used for? Whenever you put a new lamp in you have to replace the lamp timer or the projector thinks it’s an old lamp that has reached end of life and keeps shutting off. What brand is yours projector? Infocus has several models. I would recommend you join our forum as well where there are more experts to help you out. Try resetting the lamp timer first.

      • Same problem here, new original lamp installed in a BenQ W1070 but the projector indicators shows LAMP in red (meaning lamp failure). How to reset the projector without the lamp working? No meny is shown 🙁

        Sven Hammarberg January 26, 2018 2:23 pm Reply
        • Found the problem! The Benq is up and running again.
          One of the small cable connectors inside was disconnected, probably a mistake by the company I hired to clean the projector after the old lamp exploded.
          Lessons learned: Always check also the small things inside… And don’t let the lamp explode, change it on recommended lamp time instead 😉

          • Hi Sven,
            So glad this worked out and your projector is working.

          • Which one?
            I have the same problem as you, goes off, and lamp LED goes red. replaced the lamp, new one is genuine. Same thing happens.

            Erik May 29, 2018 4:43 am
          • Hi Erik,
            Two things to check: the cable connector in the lamp is secure. Then check that the lamp timer has been reset. If the lamp timer hasn’t been reset to zero. Otherwise the projector will think the new lamp has reached end of life and triggering the LED red and shut down to protect itself.

            Shelagh McNally May 29, 2018 11:06 pm
    • In your case, I would assume that either somehow the ballast board has been damaged or not plugged in, or that the interlock on the lamp cover/door is not actuating (assuming the lamp is still good, and not some cheap generic).
      Very often on projectors I see clients accidentally break that interlock. Often it’s just a tab on the door cover that presses a switch or interrupts an optical sensor to tell the projector the door is closed. If this tab is broken off, you could get a lamp error or a combination of a lamp light and other light telling you the door is open.
      If anyone suspects a lamp counter is causing their problem, in most projectors I work on, the counter is only a recommendation and the projector will still work. Some projectors will only let you use the old lamp up to 100 hours past the replacement time (I’m thinking about NEC projectors), and after that the projector will get an error and won’t come on.
      The solution is to look in your owner’s manual for a key combination you can press on the remote that will get the projector to run long enough to reset the lamp counter.

  • I have a Mitsubishi HC4900. It will not let me reset the timer. The hours stay the same. When I press the three buttons at the same time the projector powers up and the status light keeps blinking. My hours stay the same at 3784. What am I doing wrong?

    Todd Princl May 25, 2016 6:01 pm Reply
    • Hi Todd,
      Have you tried this procedure:
      Plug in the power cord and reset the lamp operation time by holding down the arrow keys and POWER buttons on the control panel at the same time about 3 seconds.
      Unless these 3 buttons are pressed at the same time, the lamp operation time isn’t reset. Make sure that the STATUS indicator blinks twice and the lamp operation time is reset successfully. The projector doesn’t turn on if the lamp cover isn’t attached securely. Be sure to reset the lamp operation time whenever you replace the lamp. Do not reset the lamp operation time unless you replace the lamp. Here is a link to the manual http://www.manualslib.com/manual/104639/Mitsubishi-Hc4900.html?page=36

  • I have the olens xpj projector. You can hear the movie playing but the picture isnt showing up. The bulb is producing light and I even tried replacing it with a new bulb that came with it…..after doing that there was a blue vertical bar for a second then it went away and continued to do the same thing the old bulb did. I cant even pull up the menu settings or anything. This is my first projector and I’ve not had any previous experience with them. I dont think mine has a timer that needs reset. Do halogen bulbs have a shelf life? Also, when one goes bad does it still produce light?

    Kimberly June 4, 2016 6:08 pm Reply
    • Hi Kimberly,
      This sounds like a problem with your diffusior or the integrator lens. You could also check to make sure the lamp is securely screwed into the projector because anything lose may cause the vertical blue bar. What kind of halogen did you buy? If it’s not authentic from a recognized OEM manufacturer, the problem may be with the actual bulb. I would contact that manufacturer and get a technician to look at the projector.

    • You may have a bad auto iris, cinema filter, or aperture controller. Many projectors will have these items to block light on the top and bottom for movies with different aspect ratios.
      Usually they will detect if the iris or aperture controller or cinema filter are bad (Epson), but some projectors may not sense this.
      If your blue bar was a horizontal bar, it could have been because the stuck iris moved enough to open up a slit through which the projector shined for a second or two. After that, the iris could have closed and blocked all the light even though the lamp is still on.
      It could also be alignment issues but I doubt that since you did get that blue bar.

  • Hello sir,
    We have changed a board which contains the ports (SDI A/SDI B) and ethernet ports ..etc. well after changing them and after installing a new lamp as well we turned on the projector, then we projected a movie and the problem was that only half of the image is projected in the cinema screen.
    is it because we got missing PCF files or is it something else. thanks

    Thanks for your great article! I have a question I recently replaced my lamp in my viewsonic projector. Now the projector works (the projector menu comes out, the light comes out of the projector) but the picture from my wii u, ps4, and cable box won’t come though. Other then the menu on the cable, that comes though but not the actual picture. Any suggestions? I have connected with HDMI and have tried multiple cords for each. Just won’t show picture from devices. Thanks, Konrad

    • Hi Konrad,
      Have you checked the setup from the WII? It may have lost the information when you replaced the lamp. Sometimes the projector goes back to factory setup when you replace the lamp and you need to reconfigure. What Viewsonic model is it? I can ask my techies here for more specific information. You can also try joining our forum where there are people there who can figure out what needs to be done. http://www.fixyourdlp.com/forum/ Sorry for the lame advice.

      Shelagh McNally August 1, 2016 1:55 pm Reply
    • I am an authorized Viewsonic ASP tech. I have never seen a projector do this.
      A great test would have been to try plugging a PC into the projector since a PC will automatically detect the correct resolution and timing. Also make sure the resolution is set correctly in the menu since that’s the only thing showing up.
      As a last resort you can also try returning the projector to factory defaults in the menu.

    • Hi Mark,
      First thing to check is the lamp timer that is has been reset to zero. The check the connections with the lamp and projector. If they are too loose or too tight this can cause the warning lights to turn on. The other problem may be with the ballast or colour wheel that can also cause these lights to go on.

Not sure if the projector bulb i purchased is defective or not. I have cleaned the inside for dust also.

    Matt Marvin August 7, 2016 8:05 pm Reply
    • Hi Matt,
      Where did you purchase the lamp? If the price was a real bargain, then the lamp is a counterfeit and the project is reacting to it because it’s not calibrated properly with the lamp. Counterfeits can’t be calibrated because they are lacking the proper technology. If you bought from a recognized dealer, then you may have a defective lamp. Contact them for a replacement.
      Hope this helps.

    • Hi Juan,
      Contact your local Sony dealership to find a local retail outlet that sells your filter. If you bought this from a retail store contact them and ask if they carry replacement parts. You can also try contacting discount-merchant.com and see if they can order you a new filter. It’s really important to have this air filter as it will keep your projector from overheating. If it gets too hot your projector lamp can explode. Good luck. Let me know how everything turns out.

    • Hi Hassan,
      It sounds like there is a problem with the laptop screen and the projector image. It may be a problem between the display resolution of the computer and projector. Try adjusting the display resolution to match the data projector. Another thing to check is that the display mode is set to only an external video port. The final thing to check is that the projector lamp has not reached end of life because that will also make the image go dim even after there is that initial display of light. I hope these suggestions help. You can also consider joining our forum for more expert help. http://www.fixyourdlp.com/forum/

  • I have a JVC hd-56fn97 and I received this TV for free and they had found it. It didn’t have a lamp in it. So I replaced it and when I did the TV would turn long enough for the lamp to warm up AMD the TV to play for a sec and then the lamp/program light would flash. Any ideas? I read it could be a circuitry issue. Could just blowing the dust off help it? Maybe fix it?

    • Hi Austin,
      This may very well be a colour wheel or ballast problem. You could try cleaning the air filters because if they are clogged they will cause the TV to overheat and turn off. It may be a circuitry issue but that would need a technician to determine exactly where the problem may be.

    • HI Yannick,
      It sounds like your air filter is blocked. That fan 1 error messages comes on when the fan is going too fast. It means that there isn’t enough cool air circulating in the projector so to compensate the fan is running faster. Trying cleaning the air filter so that there is nothing blocking it. The projector will shut down automatically is the lamp cover is open as well. Keep it closed. Here’s a link to your manual where you can check to see how to clean the air filter : http://www.benq.ca/product/projector/MS524/downloads/

      • Good afternoon,
        When I run with the cover open I “close” the switch to be able to run the projector. About fan filter there is not on this projector, take from manual “Filter free design to lower maintenance and operating costs”.
        Any other idea ?

          Not all projectors require that you change the air filter. Have you changed the projector lamp. Is there a problem?

            I can’t change the air filter because I don’t have air filter on this projector. About the lamp I didn’t change it since I use lite time.

            Almost all projectors have a filter system since it’s a crucial part of keeping the projector cooled off. What is your make and model and I can discuss it with their repair bill.

    • Hi Al,
      Have you reset the lamp timer to zero on your projector after replacing the lamp? You need to do that as a final step otherwise the projector thinks the old finished lamp is still installed. You can usually reset the lamp timer using either your remote or the menu option on the projector. What model do you have?

        • Hi Gary,
          Have you changed the projector lamp? If so check to see that it has been properly installed. Sometimes if the screws or connectors are not tight enough the projector can’t register the new replacement lamp. You will need your original remote control to reset the timer to zero. What model do you have?

      It sounds like you got a counterfeit lamp installed that hasnt been properly calibrated and is burning too low to give off the light that is needed. Did the lamp come with OEM stamps and a serial number you can check?

    • Hi Ricky,
      Where did you buy the lamp? There are cheaper priced counterfeits being sold that will pop as soon as you put them into to TV because they haven’t been calibrated properly. Have you also checked the air vents / air filters to make sure they are not blocked. If the air flow can’t get around the TV and lamp, it can cause overheating and explosions. Try to get a refund for that lamp.

    • Hi Kenny,
      If the screen is still black the replacement was not successful. Have you tried checking the connections to make sure that everything is working? What type of lamp did you buy? Sometimes the counterfeit generic lamps won’t work and keep the screen black. After checking all the connections do the following:
      Be sure to reset the Lamp replacement counter after the lamp is replaced. When the Lamp replacement counter
      is reset, the LAMP REPLACE indicator stops lighting.
      1 Turn the projector on and press the MENU button to display the On-Screen Menu. Use the Point buttons to move the red frame pointer to the Setting Menu icon.
      2 Use the Point buttons to move the red frame ▲▼ pointer to Lamp counter and then press the SELECT button. The first dialog box appears showing the total
      accumulated lamp time and reset option. If you select Reset, “Lamp replacement counter Reset?” appears. Select “Yes” to continue.
      3 Another confirmation dialog box appears, and select “Yes” to reset the Lamp replacement counter.
      That should reset the lamp time back to zero. Here is a link to your manual for further information:

    • Hi Shawn,
      Your lamp was either a generic or possibly a counterfeit. They are prone to overheat and explode. You need to carefully clean the TV using gloves and dispose of the lamp properly since it does contain mercury. I would ask for a refund or replacement from the company where you bought the lamp as two days use means there is definitely a defect. Read our article on how to clean up after these lamps. Good luck.

    • Hi Brandon,
      You did everything correctly so it’s not you. It’s the lamp you bought. It sounds like it is a generic projector lamp rather than an OEM lamp. The generics are always a bit dimmer since they don’t have the same material and specifications as the OEM lamps direct from the manufcaturer.

  • Hi Shelagh,
    I have a Sharp XR-30x that has only about 500 hours on the lamp but I’ve had the same lamp about 7 years. All of a sudden after running the projector for about two minutes, the color becomes blue-ish, then dims, and the unit immediately shuts down and shows the temp light flashing. I’ve blown compressed air through the vents (no filter on this). All 3 fans are spinning when it runs, but could this be caused by an old lamp?
    Thank you for the help.

    Brandon November 23, 2016 8:37 pm Reply
    • Hi Brandon,
      For sure those are all the symptoms of a lamp that is reaching end of life. Usually the color goes off and gets dim. You may not have reached the full hours but the parts may be reaching end of life due to old age. If the fans are running then it’s not from overheating. I would definitely look into installing a new lamp. Check out discount-merchant.com for authentic OEM lamps with good prices. Wherever you buy from, make sure they are producing authentic lamps and not counterfeits as this can damage your projector.

    I just installed a new Bulb. OEM. The Image randomly goes Black and White and flickers occasionally flashing images from earlier in a program. The tone of the Projector changes pitch and sounds jittery.
    As soon as I hit the Power button once (2 presses to turn off) the Image re-syncs. Happens randomly some times a few times a minute, sometimes not for 10 – 20 mins.

    • Hi Greg,
      Without knowing the model number it’s hard to say. But if you have installed a bargain-priced lamp it might be a counterfeit lamp. These lamps can’t be properly calibrated so the projector won’t turn on after it’s installed. Most of the time, the problem is a counterfeit lamp. Check the labelling on the lamp and the source. The reset screen not turning on is a key indicator. What is the model number? I can do some more research for you if you give me the model.
      Sorry I can’t help more but check the lamp.

          Red Power light flashing and temperature light solid red: The projector has overheated and turned itself off. Check the air filers for blockages
          Red Power light flashing and temperature light flashing: There is a problem with the fan or a sensor. Turn the projector off and unplug it. Let it cool down and restart.
          All lights flashing red: There is an internal error. You need to call a technician.

    • Hi Jeremy,
      This is the lamp. It’s not an genuine lamp and the lamp burner is not firing up enough to give the heat and therefore the light needed. One way to check if the lamp is OEM is to compare the price on the manufacturer’s website. It should be around $100-#120. If the lamp you installed was a a much lower in price then it’s not a genuine OEM manufactured lamp. Sometimes counterfeit manufacturers play around and call it “OEM compatible.” Send the lamp back and ask for a refund. If you are looking for a good manufacturer discount.merchant.com sells this lamp at a good price and it is manufactured in North America. http://www.discount-merchant.com/benq-5j-j7l05-001-replacement-projector-lamp-with-housing-by-osram.html#.WP7UMcm1ugQ

    • Hi John,
      The first thing to check is that all the plugs and screws are installed properly. A black screen usually means that the projector is not accepting the lamp connections. Where did you buy this lamp? It may possibly be a counterfeit that has not been properly calibrated and the projector is not turning on to protect itself. We have an online manual that shows how to reset the lamp timer: http://www.fixyourdlp.com/2012/11/28/replace-epson-hc-8350-lamp/
      You can use the onscreen menu but you should also be able to access the using the remote control.
      Here are the instructions from the user manual:
      Resetting the Lamp Usage Timer
      After replacing the lamp, plug the projector back in, turn on the power switch on the back,
      and press the
      power button. Then follow these steps to reset the lamp usage timer:
      1. Press the Menu button on the projector or remote control.
      2. Use the menu navigation buttons to open the Reset menu, then select Reset Lamp Hours.
      3. When you see a confirmation prompt, highlight Yes and press the Enter button.
      4. When you’re finished, press the Menu button to exit.
      The lamp usage timer shows 0H until you’ve used the lamp for at least 10 hours.
      Hope this helps.

    • Hi Meng,
      The lamp is defective and not an OEM manufactured lamp. What is happening is that the housing is not the correct size and shape so it’s not connecting to the projector properly. Since the projector is senses the housing doesn’t fit properly it won’t turn on to protect itself. You need to return the lamp for a refund. If this was a lamp bought from an certified OEM manufacturer then it’s defective. In any case, you need to get a replacement lamp and not use that one.

We have tutorials on our website for DYI changing and have never heard about technicians being approved by Mitusbishi and non-technicians being locked out of the TV. You could try this website called :http://techlore.com/article/are-you-locked-out and Mitsubishi info is:
      Mitsubishi sets use a four-digit code for a V-Chip locked program, view a locked TV, cancel the lock, or to enter the V-Chip lock menus. You can view the locked shows on the TV set by pressing the number 9 and QV buttons on the remote at the same time, whenever your code is requested. This process temporarily unlocks the TV and asks you to enter a new code.

    Derrick July 12, 2017 12:22 pm Reply
    • Hi Derrick,
      First check if the eco mode is on with the projector since that will lower the brightness. The dimming is usually connected to the lamp and it could be that one lamp is better than the other. It can also be the lamp is misaligned inside the projector. You could trying to re-install and see if that solves the problem. Finally, the color wheel may be wearing out and that sometimes causes dimming.

    Our church has a Viewsonic Pro8500 DLP. I wasn’t there but I was told that the lamp went out and was changed (not by me) and when it was powered up all that happened was the indicator lamp glowed steady blue for about 15 secs. and then went to a flashing blue.

If your model doesn’t have those arrow on the Menu area then you will have to buy a replacement original projector in order to get the projector to work.

    • Hi Jin,
      Have you cleaned your air filter? This sounds like it’s blocked so the air can’t circulate properly causing the projector to overheat and shut down. Try cleaning the air filter and see if that helps. The other problem might be the lamp itself. Is it a certified Philips lamp? Sometimes knockoff/counterfeit lamps don’t have the properly elements and the projector will respond to the fake lamp by shutting down. If you did buy a defective lamp contact the seller and ask for its certification and if that is not forthcoming ask for a refund. Hope this helps.

      With this particular model, it sounds like there is a misalignment happening of the LCD panels that creates this screen door effect — what you are describing. Try adjusting the screen distance and seating for a minimum seating distance of 1.8x the screen width. For example, you should be sitting at least 13 feet from the screen if the image size is 100″ diagonal. Your room should also be dark since that will affect viewing. For the main menu, you will need to original remote control to activate it.

    • Hi Anaj,
      This sounds like a colour wheel issue. Have you changed the lamp recently? If you installed a counterfeit lamp they can damage the colour wheel and other optics causing that type of message. But I’m not an expert. I’ll ask one of my experts in the forum what they think and I suggest you try joining our forum for more help. Sorry I couldn’t do more.

  • Hi, I’ve got an lci-98 with less than 6 hours of run time on it and the picture suddenly stopped displaying and showing a white box with lines through it, when playing a movie the colors of the movie kinda show but you can’t actually make out the pictures, I’ll snag a picture if needed so you can see.

    • Hi Austin,
      It sounds like the lamp has given out. White lines is an indication that the lamp is not firing properly so can’t get to the right temperature to handle the color changes. Where did you buy the lamp? Check to see if it’s an OEM lamp and send it back for a refund if it isn’t.

      The projector is not going to turn back on until a new projector lamp has been installed. If you have installed a new lamp and the projector is not turning on then the color wheel or ballast has been damaged. You will need to get a technician to look at it.

    • HI Kiran,
      I think this is your either DLP chip or DMD (Digital Micro mirror Device) going faulty. Several of the mirrors on the chip are probably out of alignment and not moving anymore. Check to see if this is covered under warranty. Otherwise it will be too expensive to repair. It might be time or another projector. How old is this one?

  • I have a benq w1070 that is overheating after being on for 30 minutes. I have it on high altitude mode and eco mode and replaced the lamp with an osrim bulb from discount merchants. I have had the projector for three years without problems but now im getting “fan error 1” after it shuts down. Fan 1 which is lamp fan seems to be working (its moving when projector is on).

    Tommy December 26, 2017 8:14 am Reply
    • Hi Tommy,
      You’ve done the first important step of checking that the fan is not blocked with dust. This projector actually has four fans and it you may be hearing the other three fans working. Fan 1 is the lamp fan and if this is not working the projector will soon overheat and turn off. I don’t think it is under warranty any longer unless you bought an extended warranty. I would recommend bringing it to the closest repair shop and having them try and repair that lamp fan. It may be as simple as cleaning and oiling that particular fan. Sorry for the bad news.

    • Hi Abel,
      If there was a powere surge that can make the projector blow its lamp. A simple power outage shouldn’t daamage the projector if it was plugged into a surge protector. If it was just plugged into the wall and the power went out and back on causing a blast of electricity into the projector this could hurt the lamp and then the projector will not turn on. Start by checking the lamp for any signs of damage or black spots. If there is damage, replace the projector immediately.

    • Hi Stacey
      You are going to have to open the projector up and blow out the dust. You’ve forced the dust back inside using compressed air so you’ll have to clean the inside. Put on the lens cap before cleaning and when it’s been cleaned. take off the cap and then clean the outside of the lens. Check out our forum for more info.

    • Hi Ed,
      The lamp timer resets itself so that shouldn’t be an issue. Check that the lamp cover isn’t loose as this will trigger the projector turning off on its own. Also check that you have clicked the lamp in place before tightening the two screws on the lamp. Tje fact that you have tried various lamps means it may be the lamp connector that has been damaged. It may be time to take it to a local technician.

      How old was the lamp? It may have reached end of life or was damaged when you cleaned inside. You can try uninstalling the lamp and reinstalling it to see if that gets the projector to turn on. But if your lamp is old, the projector may just be wanting a new lamp. The other thing to check is that the lamp door is properly installed and secured. It it’s at all loose, the projector won’t turn on. Hope this helps.

      This is a tricky repair because it sounds like you may have popped the ballast or part of the optics. It’s really hard to know if the part you bought was genuine OEM or a counterfeit. Sometimes parts from China just can’t be calibrated properly because they don’t have the OEM technology. IT is worth taking it into a technician and have them check it out to determine exactly what the issue is and what part should be replaced. It’s not toast yet.

    As a school we have many overhead projectors and regularly replacing the lamps.
    To save money we started to buy replacement lamps rather than the OEM ones and what a mistake. They overheat, burning the plastic and make the projector cut-out.
    We always clean out the projectors before fitting of dust so that’s not an excuse and the projector circuits are fine. As soon as we fit an OEM then it works without any problem.
    So please be aware.

        • Hi Dave,
          I’m not sure what the problem is? Us the projector working? You said the colours are more vibrant? Is there something else happening with the projector? Authentic projector lamps are more costly than generics. There is a lot going on behind the scenes with your projector lamp especially with the optics, ballast and colour wheel. OEM lamps are calibrated to work exactly with the projectors and make the optics last longer and work better. They are not going to explode and you will get 4-5 times more hours from them. The price tag does hurt up front but you do end up spending less money in the long run because you don’t have to keep replacing the lamp. The final reason for OEM is that if anything does go wrong your projector is still under warranty while if you install a generic or fake projector lamp and it damages something expensive to replace (like the ballast) you are not covered. Does this information help take the sting out of the price tag? Is there anything else I can help you with?

      First thing is check that everything is well connected and that the lamp cover door is secure. That will trip the projector. Then check to see that you have reset the lamp timer to let the projector know it’s safe to turn itself on. You can do that by following these steps:
      Restart the projector.
      After the startup logo, open the On-Screen
      Display (OSD) menu.
      Go to the SYSTEM SETTING: ADVANCED/ Lamp Settings menu.
      Press MODE/ENTER on the projector or ENTER on the remote control.
      The Lamp Settings page is displayed.
      Press the down arrow to highlight “Reset lamp timer” option
      Press MODE/ENTER on the projector or ENTER on the remote control. A warning
      message is displayed asking if you want to reset the lamp timer.
      Highlight Reset and press MODE/ENTER on the projector or ENTER on the remote control. The lamp time will be reset to ‘0’
      This should stop the power from suddenly tripping off.
      Hope this helps!

      It could be a couple of things. Check the air filters are not clogged because that can trigger the projector overheating and turning off. If the sound is heard but no picture means the lamp has reached end of life. If may have been damaged as well an this triggers the projector to turn off. It’s probably time to replace the projector lamp. Be sure to use an authentic lamp from an OEM manufacturer.

      Have you checked that the air filters are not clogged? If the air filter is blocked the fan will still run but the projector overheats and shuts down. Sometimes One fan may have stopped causing the fan locked error. Check that both are running. Another issue might be the rpm sensor in that fan is bad. The controller tracks the fans rpm and that may be the case for the warning. Start off cleaning or replacing the air filter and see if that solves the issue. Otherwise you will need to bring in a technician. Sorry for the bad news.

  • Hi!
    I have a Epson LCD Projector EB- G5200W which get some usage mostly during summertime. So I was checking it everything was ok after some months turned off. I turned it on, blue screen, Epson logo on, navigate througth the menus, etc.
    I noticed a foggy area right in the center of the image, so I decided to check: first the lamp and afterwards I would check the lens ( mabe a fungus…).
    What happened is that I have turned it off, waited around 1 hour, and remove the lamp to see if everything would be OK. So it seems, lamp inserted. secondly I remove the removable lens and noticed a small foggy area no in the lens but on the first glass surface inside the projector. Well, I thought to myself: time to go for repair/cleaning service.
    What happened is that I decided to turn it on again but, for my surprise, no blue screen, no epson logo. nothing. just a bright blank screen. turn off, turn on: blank Screen again…
    I would appreciate id you could give me a tip about this second issue.

    • Hi Luis,
      Your settings may have been reset when you took apart the lamp and lens. Here are few things to try:
      Press the A/V Mute button on the remote control to see if the picture was turned off temporarily.
      If you are projecting from a video source, make sure the Video Signal setting is correct.
      Check the Brightness setting in the Image menu (see Adjusting the Image) and adjust it if it’s set too low.
      ay button.
      You can also try resetting all of the configuration menu settings. See Restoring the Default Settings.

  • Bought a mini projector but didn’t check it was missing the front Lens that screws on top of the projecting Lens. Is there a place I can buy Lens parts?? Image is displaced as many little screens and tried lenses I have around and some seemed to work but not that clear.

      I would recommend that you contact the manufacturer directly to see if they have any distributors selling parts. It’s the safest way to go since you need that specific lens for that specific model. What is the make and model?

    • Hi Snethemba,
      It sounds like the projector lamp has reached its end of life or is close to being done. The projector won’t fully turn on to protect itself. Have you checked the lamp life on the menu to see if it’s reached end of life?

  • Hi,
    I have an optoma hd 230x, I just replaced the lamp, but even prior to that there’s a loud buzzing sound coming from the projector.
    When I open the front cover I noticed the plastic piece from the previous bulb had broken so I assume that was hitting the fan an making that terrible noise. But now after replacing the bulb and housing the noise is still there.
    I cleaned the whole inside and dusted it down.
    Any clue what it could be?

    Tahir October 10, 2018 7:34 am Reply
    • Hi Tahir,
      If it’s just the noise that is happening it might be that the fan has been damaged and when it starts to spin causes that noise. If there is a vibration accompanying the noise then your color wheel has been damaged and should be replaced. If you run the projector and it shuts down immediately when it heats up, then that noise is definitely caused by a damaged fan. The old lamp may have broken it. You’ll probably need to see a technician for either problem. Sorry for the bad news.

    I got a Samsung Dlp tv. I replaced the bulb with a cheap ($20) one. The tv worked for about a week or two. Now I have a black screen. The tv boots up with all the less on then only the power led stays on. The bulb is on I can see light. The sound is on also. Could this be a bad bulb or something else causing the dark screen.

    • Hi John,
      This is definetely the lamp. At that price it’s a counterfeit lamp and so doesn’t have the proper gases to create enough heat to produce enough light for the picture. You should ask for your money back and then buy a guaranteed OEM lamp. That should get you back on track.

  • I have a BenQ MP770 that I purchased nearly 8 years ago. It has been sitting idle in its case for the last years. When I turn it on now, it powers up and cast a light with no image; no splash screen either. The light is a bit uneven in brightness, so I suspect the lamp, but am concern with the lack of any image at all.
    Do you think it may be just the lamp or could I be looking at a bad chip?

    Neil November 2, 2018 7:55 pm Reply
    • Hi Neil,
      It’s the projector lamp. It’s has gases in the lamp to help it reach the high temperatures it needs to get that brilliant light. I would start by replacing the lamp and see if that brings the projector back to life. It’s less expensive and less hassle that trying to replacing the DMD chip or the ballast. Keep me posted on what happens.

  • After replacing the lamp, I can say that the image is somewhat brighter, but still patterned with arcs of light and shadows. Still no splash screen or image. The power light is on and green, but no other lights and none of the control buttons are responsive. I was able to power down via the power button, however. I did take a photo of the projected light, but see no way to attach it here.

    • Hi Neil,
      Did you reset the lamp timer? If so, then it does should like your ballast colour wheel has either worn out or been damaged. I would check the color wheel for mounting tightness. Sometimes the tape has come loose. You can also see if the ballast needs cleaning. It may have dust on it due to it being in storage. It may also need to be replaced.

    I bought Optoma HD141x in 2015. Lamp exploded 3 months ago, changed it, worked fine. Now the projector wont start. At first, there was a buzzing sound. Started last night before I turned it off. Now it just wont start. The power LED and the temp LED turn to red as soon as I start it. Obviously the problem is with the temp but nowhere can I find directions on how to fix the problem. Tried calling Optoma, they dont receive calls…

    • Ho Dominique,
      First thing to check is the air filters. They may need to be replaced but check if there is anything blocking them. There needs to be air through them to the inside of the projector so it doesn’t overheat. Check to see if there are any glass shards inside the projector because that can cause overheating. If everything on this end looks good then your ballast colour wheel might be damaged. Here is a link to the online manual: https://www.manualowl.com/m/Optoma/HD141X/Manual/430783?page=61#manual
      Hope this helps.

      Your lamp has reached end of life. The lights are warning lights for the lamp reaching end of life. You can try resetting the lamp hours but the projector sitting unused probably shortened the projector shelf life.

  • Hi, My BenQ w1070st as it heats up the shading and color starts getting off and keeps getting worse until the picture starts flickering on and off, press the eco blank button and let it cool off a bit and it’ll be fine for a couple minutes until it heats up again. Background: The first bulb blew up after a couple years and when I replaced it the projector worked just fine for 6 months to a year until it started shutting down and I figured out that a chunk of glass had made its way into the ducting for the little blower fan and ended up inside of the blower fan which stopped it from working and was causing the projector to overheat, it would start with the shading being off and then would start flickering and would end up shutting itself off. I replaced that little blower motor and the projector worked just fine for like another year until it started doing the same thing so I ordered another blower fan but this time it didnt fix it! Now I’m to the point where I dont know what to do other than to just start replacing things that I think it might be but might end up wasting a bunch of money and still not have it fixed, or just give up on it. lol. Any ideas?? Thanks 🙂

    Luke November 27, 2018 12:36 am Reply
    • Hi Luke,
      Have you checked lamp life? If may have reached end of life and would cause flickering and shut down. The air filter may be changing as well. If the dust remains on the filter for a longer period then it can cause the projector to shut down. Do you hear the fan blowing? It may not be turning on long enough to cool the projector. Are there any heat sources near the projector itself? Start off with checking out the lamp. If none of these work then it might be the colour ballast wearing out. Hope these tips help.

  • Hi Shelagh,
    I have an Optoma HD20. The original lamp blew. I replaced it and the new lamp worked fine for about an hour, then there was a pop sound followed by a whining fan sound and the color faded. I then turned the projector off. I took the bulb out and it seems to look OK. Should I put it back in and try again?
    Thanks for any help you can give.

    Joel Casey December 3, 2018 10:47 pm Reply
    • Hi Joel,
      The lamp is not good! That pop you heard was probably one of the connecting cables on the lamp overheating and popping. Sometimes the bulb itself is ok but the inside connections are burnt. This sounds like it might be a counterfeit lamp. I would go back to the vendor and ask for a refund or replacemet. A good way to determine whether the next lamp is counterfeit is the price. These Optoma bulbs usually retail about $85-110 dollars. Anything under $50 is counterfeit and probably won’t work in your projector. Get your refund!

      Spots on the bulb can mean there was oil from your fingers that burnt when you started up the lamp. The other option is that the lamp is defective. If you bought it online it may be counterfeit. Where did you buy the lamp?

  • I have a 6 months old Epson Tw6700. Sometimes when I start it on, there is no light comming out, and the fan speed goes on a very load/high speed. I cant turn it off with the pwr button, but need manually to unplug the power. If I leave it on a few minutes with no light comming out and the VERY high fan speed, ususally the light gets on an a clear picture shows, but once after a few minutes, the lamp and temp light started to come on…
    If I disconnect pwr and turn it on again, it pwr up normally. with normal fan speed and picture.
    Maybe one out of 5 times the fault comes with no light, high fan speed, unanble to pwr of on projector or remote.

  • We ordered a new lamp from an online company (Projector Lamps World), it was relatively cheap ($100). It worked for a few days, then it stopped abruptly and when we tried again a little while later it went on for 20 seconds or so and then the lamp light indicator went on saying we need to change lamp. When we turn on now, it stays on for a minute or so and the picture is very dim. The part we bought was Epson, the part did say Epson on it. Could it be a inferior lamp and that is the cause of this?

    Kathryn Arbez January 9, 2019 3:26 pm Reply
    • Hi Kathyrn,
      This is definitely a problem with the lamp. It hasn’t been properly calibrated to the projector so it’s not firing properly and so the dim picture. If it’s an OEM lamp, it may be damaged from the shipping. I would contact the company and ask for a replacement lamp. Also double check it’s the correct lamp for your projector. Epson makes hundreds of model but they don’t all use the same lamp. Using a lamp with a different specification would also cause the situation you are describing.

      The projector lamp will sometimes start making noises before it reaches end of life. Also the projetocr may also start to overheat and this will cause the fans to turn on which can be noisy. The lamp also starts to be less bright so the picture on screen dims.

    • Hi Luke,
      First check that your filters are not clogged with dust. If there are not clear enough to let the air circulate the projector will overheat and shut down to protect itself. Also check the lamp hours. Those blinking green lights may also indicate that the projector lamp has reached end of life and needs to be replaced.

    Tom April 2, 2019 6:58 am Reply
    • Hi Tom,
      If could be a couple of things. It might be the new lamp is giving you that jump in brightness so you are noticing that pink line now. The location of the pink line points to a damaged diffusers or something else the optics getting burned. Sometimes when replacing the lamp, the PLC bands moves slightly out of position and causes pink and blue, or yellow and blue bands depending on the type of projector. A service technician might be able to realign them. I would not attempt this repair unless you are highly technical. There is a link showing what needs to be done: https://sites.google.com/site/epsonpowerlite5500c/home
      However, this does seem to be a design flaw with this series. It seems heat over time eventually causes this issue. Is it still under warranty? Try contacting Epson and discussing the repair for the replacement part with them.
      There is a much longer stream explaining the whole issue on the AV Forum: https://www.avsforum.com/forum/68-digital-projectors-under-3-000-usd-msrp/1458911-epson-8100-replaced-bulb-now-pink-blue-bands.html

  • Hi Shelagh
    Have found a very old projector in the loft (Kindermann). At the moment I have no slides. The thing (sorry to be so non-technical but I know nothing about projectors – the last time I saw one was in the 1980s!) that makes the slides move along and the kind of arm that pushes them into the slot are a bit stiff and temperamental and sometimes make a grinding sound (both when going backwards and forwards). It’s been given a good clean and is slightly better but still hit and miss. Also there is a thing inside that is blocking light getting from the bulb to the lens (a big black rectangle) that I presume is supposed to move out of the way when viewing the slide, but it isn’t. Please do you know what is wrong and what I can do to fix it? Or do you only advise on modern projectors? Any help would be much appreciated.
    Kind regards

  • I have a BenQ projector s/n PDX6B01480000, the bulb when out after receiving notifications on the screen. I did purchase a new bulb and installed. I double checked installation, but the projector starts when I press the power button but then the lamp light indicator turns red and it shuts down. The bulb looks like the original. I did have one of the wires come off the bulb terminal during an earlier installation which caused the GFCI to activate at the wall outlet. However, I re-installed, re crimped the connectors. Not sure if I should buy a new bulb and try it again. Thoughts?

    • HI Jeff,
      Where did you buy the lamp? A wire coming off during the set-up indicated this was an counterfeit lamp and should be returned. You probably did an excellent job repairing it but the connection probably wasn’t good in the first place. If this is an older projector and no longer being in production, your best option is to look for a generic lamp. It will still work properly. Jut avoid the low-priced Amazon counterfeits. There are some good sellers of generics that are reliable such as Aura, Exclusive Bulbs or Lutema. Try putting in a new bulb and things should be back to working.

  • Hi Folks, I have a Dell 1800MP projector that appears to have lost one colour (Red I suspect) on both the VGA and the video inputs. When you remove a source from the projector it displays a perfectly white blank screen, then returns to the the splash screen which is definitely incorrect. It initially went perfectly for a number of hours, then when I was using it and it lost the colour and at the same time I noticed a hot smell coming from inside, but no smoke 🙂 Since then it shows a missing colour when a source is applied. Any ideas are welcome – I am a service tech, but now retired 🙂

    Terry Sutton August 10, 2019 8:17 am Reply
    • Hi Terry,
      The first thing to check is the lamp. Did you recently install a new lamp? If not, then the lamp may be reaching end of life and need to be replaced. If you did install a new lamp, it may not be an OEM lamp but a counterfeit not calibrated for your machine.
      You could try resetting the projector to factory defaults to see if that correct any color settings that have been set up. If you can bring up the on screen menu you can go to All Images, and adjust the Color Settings. You can also try adjusting the color saturation, sharpness and tint in Video Images. You should also check the connecting cables are the ones needed for the VGA inputs. If it’s not the proper HDMI cable that can cause color to drop.
      That hot smell could be the lamp or the colour wheel ballast. Are the fans working properly? These projectors have been known to have bugs with their capacitors that affected lamp performance. If it’s under warranty call Dell directly and if it’s out of warranty try calling (800) 941-4478. You may need to get more diagnostics done to pinpoint where the problem is. Most of the time with bad pictures and projectors it’s the lamp, capacitors or ballast wheel causing the bad coloring.
      Hope this help.

      Shelagh McNally August 11, 2019 6:29 pm Reply
  • Hi Shelagh, Many thanks for your reply, the lamp according to the internal clock is only 500Hrs or so, so I wouldn’t suspect the lamp hours. The fan is fine as are the cables, I initially suspected the cables/or on board sockets, but with substitution and trying both VGA inputs had the same result.
    The interesting thing with it is, when it is initially powered on it comes up with the splash screen with the Blue “Dell” Logo on a white background all nice and crisp, then after a few seconds – maybe 10 – 15 secs the background changes to a mid green, and stays that way even while it is automatically searching for an input, if a source is found, say VGA, it has the green cast across it. I tried a pure video source and had exactly the same result. If the source is removed, prior to the start of the automatic input searching it produces the pure white background with the Blue “DELL” Logo, then changes, as before, to the green screen and the input search.
    This makes me suspicious that the colour wheel is out of sync with the incoming source, or not being triggered correctly, maybe this could be due to the Colour Wheel “Ballast”, whatever that is, has been damaged. I dissassembled the machine and had a physical look at the motherboard the powersupply’s and the cap’s and they look to be fine, but didn’t venture around the colour wheel and the light switching department 🙁 I have repaired a fair number of “Bad Cap’s” in powersupplies and other gear so am aware of what they look like!!
    Any further thoughs are welcome 🙂

    • Hi Terry,
      It does sound like the ballast wheel is not synching up. You’ve covered all the other things I was going to suggest. It makes sense it’s the colour wheel because as soon as it starts reading input other than the factory default logo the colour goes green. Are you comfortable changing the ballast?

      Shelagh McNally August 16, 2019 11:44 am Reply
      • Thanks Shelagh, If I knew what the ballast looked like, no doubt I could do so 🙂 Where would I source one to do an exchange ?? this machine being a “Dell” !! A circuit of the thing would certainly help, but naturally, they are as scarce as hens teeth!! 🙁

        • Hi T.D.
          The ballast is also called the color wheel. You should be able to find one on e-bay if you search using the projector number. You may also want to find a technician in your area who would replace it. Unless you are familiar with electronics changing a color wheel for the first time can be tricky.

    It works as a charm, but after 60 seconds the image flickers and then shuts down.
    Do you have any advice on what could cause this ?

    J November 25, 2019 11:36 am Reply
    • Hi J,
      First thing to check is that you have reset the lamp timer to zero. If this wasn’t done the projector is still reading the old hours and thinking the lamp has reached end of life so it shuts down. If that has been reset and the problem persists, then try re-installing the lamp making sure there are loose connections including the projector lamp cover. The final problem might be the lamp itself. If you bought a counterfeit lamp (easy to do these days), it may not been calibrated properly so that the projector turns on it can’t properly read the lamp. You would need a new lamp. Hope this helps.

    chad w November 27, 2019 8:25 pm Reply
    • Hi Chad,
      Flickering seems to be a bug with this model. It’s usually related to issues with the bulb striking. If your bulb is a knockoff or bought from Amazon, chances are it’s a counterfeit and that striking is from bad parts. If it’s a good lamp that you trust run the projector in “torch” mode for a few hours and is supposed to fix the bug.
      Hope this helps.

    • Hi Jamm,
      First check the air filters and make sure they are free of dust and debris so that air can circulate properly. Your projector lamp may have exploded or melted — often the case when the projector overheats. If the projector lamp is not working the projector will not start up to self-protect. Check the lamp to see if there is anything loose or burnt out, If after you replace the lamp the projector doesn’t turn on it means the color wheel ballast has been burnt and will it will have to be serviced by a technician. Good luck.

    Victor Garcia December 17, 2019 9:31 am Reply
    • Hi Victor,
      It’s most likely the lamp. Have you checked to see the lamp hours? If it’s reached end of life or if any warning signs come on screen it means your projector will automatically shut off to protect itself from a lamp that is about to stop functioning. The other thing to check are your filters. This model has a side filter which is easily checked. If the filters are clogged, that can also make the projector overheat and it will shut down. But most likely it’s your lamp which needs replacing.

The first thing I did when I got home was download a manual and look up how to determine the hours it had been used. I discovered that the only hour counter is related to bulb life, and can be user reset, and once that’s done, it starts showing an hour count at….10 hours. What a coincidence.
    I then pulled the dust filter, and gave it a rub with a Q-Tip. See pics: https://imgur.com/d1MVWJp . The first pic shows the Q-Tip with the dust, as you can see, the filter is showing the impressions of the grate of the housing. This seems to indicate usage that vastly exceeds the 10 hours claimed.
    Is there any way to tell if the seller has reset the hour count without changing the bulb? Can the bulb or the housing show telltale signs of use as the lifespan moves along?

    • Hi Patrick,
      My apologies for the late replay. I’m afraid you have been lied to by this reseller. You can absolutely reset the lamp timer to zero and put the old lamp back into the propjector. Judging from the filter this projector has been used for months and many hours. It takes a long time to build up that much dust on the filter. That being said, once you replace the lamp and filter, the projector should still have some life left in in it. These Epsons are very sturdy and built to last. I hope you didn’t overpay too much for it. Good luck.

  • I haa bulb blown on my BENQ WX1070 and suspect that as mentioned above ‘When this happens, the projector temperature controls will go off’. I have fitted a new lamp but get the red lamp warning and cant see any loose connections and the door catch looks ok. Any suggestions on getting it to reset?

    • Hi Steveev,
      Check that there are no parts of the blown lamp left in the projector. Check the filters. Reset the lamp timer to zero because unless it’s at zero the projector will think the lamp is still old. Verify that the lamp is OEM and not a counterfeit lamp since this will set off the read lamp warning as well. If none of these work, then your ballast color wheel may have been damaged when the lamp blew. You will need to take it to a technician in that case.

  • Hi,
    Thanks for your answer. (I replied to your reply but I can’t see where my post went to)
    I replaced the lamp and put exactly the same reference: Osram P-VIP 280/0.9 E20 9n. I’m pretty sur it’s properly installed.
    The projector starts, I reset the lamp timer, but after ~3 minutes it says there’s a “fan failure, the projector will turn off”.
    All the fans turn correctly.
    Do you have any guess, or should I unmount the whole projector to check if there’s a broken part ?

    • HI Jeremie,
      Your filter is probably blocked and needs to be either cleaned or replaced. Even if the fan turns on if the air filter is blocked, the projector will overheat. You should also unmount it and see if there is any broken lamps part or anything blocking the fan and see what the filter looks like. Also double check that the lamp is genuine. This is an older model and while there are generic lamps that are good, there are also a lot of counterfeit that are not calibrated to work with the projector and that can trigger these warning messages.

  • I have a Vivitek 963HD projector. Turning on the projector has been a problem as the lamp will not light up until after a few tries if it will at all. I replaced the lamp with a genuine Phillips brand bulb and cannot get the projector lamp on or if I am able to, it may take more than 10 tries of it trying to go through the boot up process. After checking the blinking light error code in the manual, I have discovered that the error is “Lamp Fail 2”. Does anyone know exactly what this means? *This error is different from the “Restrike Lamp Failure” error.

    • Hi John,
      Did you reset the lamp timer? If that has not been reset to zero you will get that Lamp Fail 2 error message. Also check that the lamp cover has been properly re-installed. Under the Status Menu check that the lamp timer has been reset to zero. Sometimes it doesn’t automatically and you can do the factory reset to put it back to zero. If it’s not the lamp then it may be the actual board or ballast that have gone and it that case it’s not worth repairing as this machine is out of production. Hope this helps.
