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

DLP Projector troubleshootingThere 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.

      Hi Masta,
      Can you give me some other details? I’m not sure I understand what the problem is.

    Hi Shelagh: I’ve just replaced the lamp on an Infocus projector but no light is coming through. The projector is definitely connected to power as I do hear the fan running but the usual set up lit screen is not coming on. Also rechecked my connections from the replaced lamp to its power source and it is definitely plugged into the correct place in the correct way. Any ideas???

      Hi Elizabeth,
      Did you reset the lamp timer? if that wasn’t done then the projector will think it’s still the old lamp. If sounds like you have all your connections in place and everything secure. It might be the lamp itself. Where did you purchase it? If the price was unbelievably cheap then it may be a counterfeit. Often these lamps are not calibrated properly and are missing some key parts that let it talk to the projector’s optic system. I would try to lamp reset but if you can’t even get the screen to light up, it’s the lamp. Send it back and ask for a refund. Buy an OEM projector lamp with a certificate from Philips. They are more money upfront but in the long run save you time and money. Hope this helps.

      Hi Heather,
      Did you reset the lamp timer on the projector? Sometimes that crucial final step is forgotten and so the projector thinks it still operating with a lamp past its prime. Check that first and it it doesn’t work then it’s possible the projector’s color wheel or ballast was knocked loose. You will have to get a technician/service guy to check it out.
      Hope this helps.
