DLP Troubleshooting Guide: My projector won’t turn on!

Trouble Shooting Guide: DLP Prpjector won't turn onThere are several reasons that your DLP projector may not be turning on.

Before contacting your service rep or paying for a costly check-up, try these 5 troubleshooting tips.

  1. Check your power: Is the power cord plugged in? Is the main power switch to the projector turned on?  cord. Has it come loose? Check to make sure the power cord is plugged in and the main power switch is turned on if the projector—including the fan, doesn’t operate at all.
  2. Check your connections. Is the image source connected to the projector? Are the cables between the projector and computer secure?
  3. Check your batteries. If you usually turn on the projector through the remote control, check the batteries.
  4. Check your temperature. Your projector has a built-in safety feature that shuts down the projector if it starts to overheat. Check that the filters are clean so air can circulate and keep the projector from overheating and shutting down. Your projector will have a status indicator that will flash if the projector is overheating.
  5. Check your lamp. If the projector lamp has exceeded its lamp life, the projector automatically stops working. The Lamp Replace indicator on the projector will be lit up or perhaps blinking. You may also have noticed a change lamp message appearing on screen  (have you been ignoring the message?). Be sure to buy only genuine projector lamps from an authorized dealer.

If none of these steps work, then consult your manual and call you local service representation for an appointment to check the computer.

If you’ve run through this checklist and your projector is still not working, contact your local repair centre.

    Power light behind power button is flashing.and projector will not turn on

    • avatar Shelagh McNally says:

      Hi Chan,
      What model projector do you have? Usually the power lighting flashing is means the projector lamp needs to be replaced. If you give me the projector model and brand, I can find out what the green light means.
      Cheers,

          Hi Jennifer,
          I would need more information in order to help you. The first thing to check is how old the TV lamp is and if it has been replaced lately.

      Hi I have an optoma hd33 and it won’t turn on I have just replaced the bulb the power light just flashes blue

      • avatar Shelagh McNally says:

        Hi Patrick,
        Have you reset the lamp timer? If you haven’t reset it to zero hours the projector will think the current lamp is the old one that has run out of life.

    I have a Mitsubishi wd92a12 and just replaced the lamp on it. Now it won’t turn on all it does is blink a green light for 30 seconds then turns on for 30 seconds then turns off… Help please

    • avatar Shelagh McNally says:

      Hi Roger,
      There is a bug with this model with the green blinking light. If the installation went smoothly then try this troubleshooting tip:
      Press the “reset” button and hold for 10 seconds. You can also try to Press Power and Display buttons simultaneously and hold depressed for 20 seconds. This should turn the blinking green light turn to solid green.
      If not try unplug the TV from it’s power source for between 5 minutes and 24 hours. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box.
      Rehook everything and then turn the TV to see if the blinking light has disappeared. If the green light continue to flash you may have failure of the DM Module Capacitors or a EEPROM Board failure or power supply failure. I am not an expert though. This website can give you more information: http://www.techlore.com/article/mitsubishi-blinking-green-light-repair-procedure.

    Can anyone tell me what my blinking light mean on my projector when the projector is turned off I have a steady red light when I turn it on the red light blinks turns to green and the status light lights up red It was working fine and then stopped my projector is a miss you Beashea XD206u. Please email me if you have any clue what this means

    • avatar Shelagh McNally says:

      Hi James,
      Your projector lamp probably needs to be replaced. If the lamp life has reached its end of life, the projector will turn on briefly and then turn off toe protect itself when it detects an old lamp.

    I’m having some trouble with a Mitsubishi HC900 projector. The projector powers on with two green lights (power and status) but there is no lamp output at all. I have two new lamps and an old one that should still work, but none of them will output anything.

    I tested it with the lamp door open (while holding down the switch) and noticed each lamp powers on for a split second then shuts off. The projector continues to run with green lights but the lamp doesn’t come on. The fans also are running.

    It’s possible that all three lamps are bad but a little unlikely. I’ve gone through the manual and searched for a few hours and haven’t found anything similar to my problem. Any ideas to point me in the right direction would be greatly appreciated!

    • avatar Shelagh McNally says:

      Hi Nick,
      How old are the lamps? When was the last time they were replaced? If the lamps are powering on and then turning off, the lamps may have reached end of life. The projector is reading them as end of life and shutting itself off to protect itself. I would start with putting new lamps into the projector and seeing if that solves the issue.

    I have an Optoma 141hdx that has a flashing red power light and a solid red lamp light. The lamp lights up the colour wheel spins and then stops on a colour then the light fades out. This repeats 3 times before the red lights appear. The bulb had about 1000hrs but I have just tried a new bulb and the issue is still there. Has anyone encountered this before?

    • avatar Shelagh McNally says:

      Hey Jason.
      This sounds lke your color wheel or ballast needs to be replaced. The sign that it is stopping on a colir and then fading out is a good indication that the color wheel is faulty. Sorry for the bad news.

      Shelagh

    • avatar Shelagh McNally says:

      Hi Jason,
      It sounds like your color wheel needs to be replaced. When the wheel spins but gets got on one color, it’s an indication the ballast is worn out.

    Hi,
    I have a Dell 2400MP that won’t power on.
    It’s plugged into a known good power source, and when I plug the power cable into the device all lights flash on top for a millisecond, and then nothing when I press the power button.
    The cable fits snugly into the socket, so I don’t think it’s the connection.
    Could this be a bad lamp?

    • avatar Shelagh McNally says:

      Hi John,
      Did you reset the lamp timer? That’s the final step for replacing the lamp. Until it’s reset the projector thinks the lamp is still old. To reset the timer: Reset the lamp usage going to the On Screen Display Menu and finding the Lamp Reset menu. Scroll down to Lamp reset and choose Yes. This resets the timer to zero and the projector should turn on. The other problem might be the lamp itself. If it’s a generic lamp sometimes the projectors just can’t work with them. Hope this helps.

    Hi,

    I have an Optima HD142X I bought last year. I use it very irregularly and haven’t used it since October. I turned it on yesterday and the fans turn on, however the lamp doesn’t, then I get a solid lamp light with flashing red (the instruction manual says lamp malfunction). I wanted to get a new lamp and give it a shot but I could not have used factory installed lamp more than 50 hours. Could it be something else?

    Thanks

    • avatar Shelagh McNally says:

      Hi Brock,
      You could try cleaning the air filter and checking all the lamp connectors. You could also take out the lamp and re-install it to see if it will turn on. Sometimes this helps but the lamp could also have been damaged if the projector gets moved around a lot. Hope this helps.

    Bought a new lamp for my Mitsubishi. Turn the TV and and a picture does come on but then flickers and turns itself off.

    • avatar Shelagh McNally says:

      Hi Michael,
      First check that all the connections are secure and there is nothing loose. Sometimes a connection that is not fully engaged can cause this problem. The other thing to check is whether the lamp is an OEM authentic replacement lamp. If you bought it online from one of the larger sellers and the price was very low, then chances are it’s a counterfeit lamp that has not been properly calibrated to work with the TV optics. The TV fires up and then reads that the lamp is not calibrated and shuts down to protect itself. Ask for a refund from the seller and then buy from a registered OEM dealer. That should solve your problem. You can read more about http://www.fixyourdlp.com/2011/12/02/7-tips-for-spotting-counterfeits/
      You can also check our forum for more help on this issue. Please let me know how everything works out.

    Hi my problem is when the movie play the lamp is on after a few minutes the lamp shutdown . And the warning air felter intake model cp 2215

    • avatar Shelagh McNally says:

      Hi Dennis,
      You need to clean your air filters as they may be clogged and causing the projector to overheat. The other problem might be that the projector lamp has reached end of life. What brand is your projector? We have a library of manuals and you could probably look up yours to see if the end of lamp life warning lights have come on. The projector will also shut down after a few minutes if the lamp is getting old. The projector shuts off to protect itself. Hope this helps.
      Regards.
      Shelagh

    • avatar Shelagh McNally says:

      Hi Dennis,
      Start off cleaning your air filters. If they a dirty or clogged they will cause the inside to overheat and the projector will turn off to protect itself. Your lamp may also need replacing because it as reached end of life. I’m not sure what brand you have but check our library for your manual at http://www.fixyourdlp.com/category/projector-manuals/ and check t se if the lights are on for warning about end of lamp life. The projector will also shut down if the lamp timer says the lamp has reached end of life. Hope this info helps.

    MP610 turns on lamp turns on white no on screen display, lamp turs off, green light stays on and fan is running.
    What could be the problem

    • avatar Shelagh McNally says:

      Hi Jose,
      This sounds like your lamp has reached its end of life and needs to be replaced. If the full lamp hours has been reached, the projector will read the lamp timer and shut down to protect itself. Usually the green light on this model is the indicator for lamp life and when it lights up it time for a new lamp.

    Hello everyone,

    Help! I bought a Dell 2400MP from ebay. It was advertised as “as new, no flaws”. Once I hooked it, the image has a deep green discoloration on it and there’s a weird smell of something burnt / burning. I used to own another piece of the same model and I know this is not a normal behavior. Any ideas of what could be wrong with it? Naturally, I need to initially diagnose the problem so I decide on my next step with the seller (potenial cheater) who sold it to me. Thank you.

    • avatar Shelagh McNally says:

      Hi Mragga,
      This is a counterfeit lamp. It has all the classis signs. Ask for your money back as this lamp can never be properly calibrated to work with your projector. Sorry for the bad news.

    Hello! My Acer Projector X1161P wont turn on, when i click the power button it stays red it should turn blue. I just used it last night.

    • avatar Shelagh McNally says:

      Hi Bonne,
      That is a sign that your lamp has reached end of life. You can check the lamp life under the management menu. How old is the lamp? Have you ever replaced it? The other thing to check is whether the air filter has become clogged.

    Good evening! I own a Sharp XVZ-17000 projector and it’s worked perfectly for 5 years. Tried to turn it on yesterday (I watched it the day before with no problem) and the projector itself powers on, solid green light, the lamp light blinks green (as it always does to warm up) I hear the fans on and then the bulb never illuminates and after about a minute, the lamp light starts blinking red and the power light starts blinking green and then after about another minute the projector shuts itself down and keeps a steady red bulb light and red power light. This bulb is only about a month old. I’ve used a vacuum to suck out the housing and vents. Taken the bulb out and put it back in. Reset the lamp prob 20 times. This projector has been perfect and I have no idea what’s going on. I had just used it about 10 hours prior to trying to turn it on. Any help anybody could give would be so appreciated! Thanks so much! (Apologies if this posts twice)

    • avatar Shelagh McNally says:

      Hi Elyse,
      Two things. The lamp you bought may be a counterfeit lamp. Did you buy it from an OEM recognized manufacturer? What you describe is a lamp that is not firing properly and getting the temperature to illuminate the screen. This happens with some generics and counterfeits is that they don’t have the right components to work with the projector. I would send the projector lamp back and ask for one with an authentic projector lamp. Did you touch any of the optics while vaccuming? That can damage your colour wheel optics. Try getting a new lamp first and check it for an authenicity label.
      Hope this helps,
      Shelagh

    I have a Christie cp2000i Project but it won’t power up due to network connections

    • avatar Shelagh McNally says:

      Hi Muna,
      This projector should be working with or without a network connection. The problem might not be the projector but the with the network. Are there any warning signs appearing on the projector indicating that the projector lamp is nearing it’s end of life? I would recommend disconnecting the projector from the network and seeing if it turns on. If it’s connected to a computer then check that connection.
      Good luck.

    I have a Brookstone big shot UST that is about 7 months old. The other day it was plugged in but now powered on, I unplugged it and plugged it back in at a different location in my room, only to find that the projector would not come on. It is stuck with the LED power button indicator flashing red and pink. No matter what I try I cannot get it to turn back on. I also noticed that the projector is coming up as an available bluetooth connection. I do not believe that the bulb has burnt out but I am no expert

    • avatar Shelagh McNally says:

      Hi John,
      The problem may be with the bluetooth connection. You may have triggered the Bluetooth audio feature by unplugging it. Try holding the
      Bluetooth Audio button to power off the projector lens and then back on. You can also try turning off the projector, press the restart button, and power back on. This should reset everything as well as the projector lens.
      Hope this helps.

      Try doing this: hold the Enter button on the projector’s control panel for seven seconds to unlock. That should unlock the control panel.
