6 common problems after installing a new projector lamp

6 problems after installing a new projector lampHere are solutions to the six most common problems that happen after installing a new projector lamp!

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.

when replacing your projector lamp goes wrongProblem #3: The picture is fine but the 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: Clean the fans and filters. Replace the generic lamp.

Projectors will turn themselves off automatically if they detect any problems. Cleaning the projector of all dust and dirt will make the 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 colour wheel may need to be replaced.

Usually the color is off with an older, dimmer lamp. However, since the projector lamp only has one color – white – the problem is usually with the internal optics. The color wheel or other optical components may have been damaged while the lamp was being replaced. 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.

    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?

    1. Shelagh McNally

      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.

    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?

    1. Shelagh McNally

      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.

    recieved 59 in projection as present. after 4 months the tv started to go off by itself. i have replaced the lamp,the
    stupid t. keeps going off every 30 minutes to 2 minutes im going bonkers.

    1. Shelagh McNally

      Hi John,
      Did you reset the lamp timer to zero? If it’s wasn’t reset when the lamp was changed that can cause automatic shutdown.

    Hi there!
    i have a benq w1100.Yesterday as i was watching a movie i pressed the pip button and it stuck completely.
    I took the power cord out and replugged it.since then the projector will not operate.The lamp starts(no image) and after 10 sec you can see the image flashing and then the lamp goes off.
    What can be the problem?
    I am leaving in iraq and there is no service here!
    Please Help!thank you!

    1. Shelagh McNally

      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.

    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.

    1. Shelagh McNally

      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
      Regards,
      Shelagh

      1. Joe

        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?

        1. Shelagh McNally

          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.

    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.

    1. Shelagh McNally

      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.

    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?

    1. Shelagh McNally

      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?

    1. Shelagh McNally

      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.

    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

    1. Shelagh McNally

      Hi Achraf,
      This sounds like a color wheel problem and not a software issue. I would suggest joining our forum at http://www.fixyourdlp.com/forum/ where there are more experts to help you out.

  10. Konrad F.

    Hey Shelagh,
    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

    1. Shelagh McNally

      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.

    I have a Mitisubishi xl2u and have replaced two separate new lamps, it still won’t start the lamp. initially, the power and lamp leds are green, then the power led turns red and the lamp stays green but starts blinking. after about 10 seconds, it turns off. same on every restart. has done this with two new bulbs. only info i can find says it’s ok, that’s the lamp protection circuit working, but these are new lamps. anyway, fan runs fine. could i have two bad new bulbs? can i test them somehow, or do a voltage test on the bulb connectors inside the unit? thanks in advance

    1. Shelagh McNally

      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. I would suggest also joining our forum at http://www.fixyourdlp.com/forum/ where there are more experts who can help you figure out what the problem may be.

    Hello,

    I have a Dell 4220 DLP projector and just got a new bulb and put it in and reset the timer and every time I turn it on it works for a minute then the colors start flashing and the projector shuts down then the Amber light bulb warning light comes on. Not sure if the projector bulb i purchased is defective or not. I have cleaned the inside for dust also.

    1. Shelagh McNally

      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.

  13. Cameron Clayton

    Hello! I replaced the lamp on my projector, went to turn it on and it started making a fast and pitched ding/clicking sound. The power button blinks and the button that says lamp auto lights up red (btw this is a viewsonic) and the fan runs. It did this when I first installed the lamp, then all of a sudden it worked for a few days, but now it is doing the same thing. Any ideas?

    1. Shelagh McNally

      Hi Cameron,
      Did you reset the lamp timer? Also check the connections on the lamp, if they are loose then that can affect the working of the lamp.

    Hello. I´ve just replace the lamp of my proyector Sony bravia Sxrd VPL hw10. The new is an original, but it doesn´t have a new air filter.

    Trying to clean the old filter, I´ve broke it completely….sight..

    What can I do? I don´t find any place to buy a new one and neither find how to build one. Help me please!!
    Thank you

    1. Shelagh McNally

      Hi Juan,
      Contact Discount Merchants at http://www.discount-merchant.com at 1-800-281-8860 and they can help you find a replacement filter. They are not hard to find for this model. Don’t feel bad. Broken filters are easy to replace and it happens a lot that people break them. Good luck.
      Cheers,
      Shelagh

    2. Shelagh McNally

      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.

  15. Hi. My projector sounds well but suddenly the image quality dropped. It be haves like a very low contrust ratio projection. When i open an image by laptop it clear for a very fractional second but turns to darker. Seems like any sofware adjustment going wrong rather than the lamp or lcd panel.help please.

    1. Shelagh McNally

      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?

    1. Shelagh McNally

      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. I’m not enough of an expert to figure this out so I suggest joining our forum where there is a community of TV experts who can help. http://www.fixyourdlp.com/forum/

    Good afternoon,
    I have a Benq MS524 form less than one year. Yesterday trying to make a protection the machine shutdown with error code led “fan 1 error”.
    I didn’t use much so I really don’t think the lamp life is over.
    I try to run the machine with the Lamp cover open and same problem. Fan is run well and even speed increase about 20 sec before shutdown.
    When start form cold period the machine run for about 2 mn only.
    Any help will be appreciated. I’m in Mozambique and not technician have knowledge for this kin of projector.
    Thank you.

    1. Shelagh McNally

      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/
      Hope this helps. Good luck!
      Cheers,
      Shelagh

      1. Yannick M

        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 ?
        Thanks

        1. Shelagh McNally

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

          1. Yannick M

            Hi Shelagh,
            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.
            Regards,
            Yannick

          2. Shelagh McNally

            Hi Yannick,
            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.

    I just replace a new lamp on a vivitek projector, but cannot turn on, the power button keep flashing, what can I do?

    1. Shelagh McNally

      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?

    I have Acer 6510bd just replace bulb and after 100hr i notice its goin dimmer also when i turn on eco mode cant see any difference (defo see diference before) looks like lamp workin on eco mode all time even i turn on full Power …. Question is … Bulb or projector problem ??

    1. Shelagh McNally

      Hi Robert,
      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?
      Cheers,
      Shelagh

  20. Ricky

    I’ve just replaced the lamp in my 60 inch Mitsubishi TV and 4 hours later it blew out again,what will make it do that?

    1. Shelagh McNally

      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.
      Regards,
      Shelagh

  21. Tim

    We have a Viewsource Pro8500 projector. The picture would cut out randomly and we got a new bulb for it. We installed the bulb but it’s not lighting up. The power light stays solid for about 18 seconds. There seems to be a lack of fan movement, as well. Any ideas? Thanks.

    1. Shelagh McNally

      Hi Tim,
      Did you reset the lamp timer after installing the new lamp? If the timer is not reset to zero then the projector thinks the new lamp is still the old lamp that has reached end of life. Hope this helps.

      Shelagh

  22. Kenny Stancil

    I have a promethean model PRM-20A(S) and the bulb went out. I have replaced it but I can not reset the timer do to the screen being black. What do I do?

    1. Shelagh McNally

      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:

    Hello i just replaced a bulb cartrage case with a new bulb for my mitsubishi tv and everything worked great for two days and i was just watching tv and heard a pop and went to back and pulled out the replacement and the bulb must of popped because it is shattered and when touching the casing for bulb it was super hot….so does this mean my filters need cleaned before i attempt another replacement bulb is that causing this to pop my bulb?

    1. Shelagh McNally

      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.

    I have a Panasonic Ae4000 project. I just replaced tge bulb with oem osram bulb. Timer/lamp hours has been reset. Picture is much more dim. Also doesnt seem to change when i go from eco to normal mode. I have installed and reinstalled to make sure the bulb is lined up and its still dimmer than the original bulb i replaced at 2200 hours.. Any suggestions?

    1. Shelagh McNally

      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.

  25. Deborah Holtzscheiter

    Hello. I have NEC V260. I may have missed it but I never saw anything about needing to replace the bulb but one day the lamp just stopped working and the status was a blinking red light. I bought another lamp housing unit and replaced it. I can’t reset anything with the remote because the lamp is not coming on. I’ve made sure everything is securely in place. I’ve pushed the HELP button as the manual said to do but I still have no light. I appreciate any suggestions. Thank you, Deborah

    1. Deborah Holtzscheiter

      I took out the new lamp. Put it back in and it worked. It’s magic. And I did check the lamp hours and it was at 99% so I had reset it.

      1. Shelagh McNally

        Hi Deborah,
        Great! I had just answered you other posted suggesting you try re-installing the lamp again. Sometimes on this model if the lamp connectors are off, the project won’t allow a reset. Glad we could help out!
        Cheers,
        Shelagh

    2. Shelagh McNally

      Hi Deborah,
      Check all your connection. Sometimes if the lamp is not securely connected the projector won’t reset on the NEV models.

    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.

    1. Shelagh McNally

      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.
      Cheers,
      Shelagh

    Hi,

    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.

    I’m puzzled. Any ideas?… I was thinking it’s a power issue?…

    Thanks for your time.

      Hi Omar,
      This sounds like a color wheel problem with the images going black and white. It could also be your power source but usually these ghost images and color issues are the ballast and color wheel. What brand and model of projector do you have? You could consider joining our forum as well where there are more experts who can help you. http://www.fixyourdlp.com/forum
