Re: New Lamp, still no picture

You may want to call in for service, the red lights mean that there is a temperature problem internally.

I've just replaced the lamp on my Panasonic PT-LM2E projector and it will switch on but no light comes out. The previous lamp blew in the projector after around 2000 hrs. The indicators are as...

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

Red power, blinking red temp


if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.

If you try to turn on the projector a fourth time without replacing the lamp, the projector will not turn on.

Press ON, INPUT, UNDO, left arrow, ENTER and right arrow on the projector in order, and then press ON.
The lamp 0000H is displayed on the lower left of the screen.

I have an Infocus 5000 projector that we have just tried to replace our 2nd brand new lamp. Each time we attempt to replace the lamp we get no picture and the red light blinks once so often. At first when...

be sure and reset the lamp hrs. But you really need to make sure you haven't pushed the lamp connection in the lamp housing out of its cubby hole. I've seen this alot, the connection gets pushed in and when you think you have the lamp in, it's not really connected. Really the only way to check this is to remove the top cover. Before you do this though, one other thing that can happen is the lamp door gets mishapen due to the heat from the lamp and can cause the thing that pushes against the safety switch when the door is on not to depress it fully. you can power the unit up while holding the switch in with something non conductive to see if it is in fact the lamp door. anything beyond this is likely the power supply/ballast being defective, or the blower fan in the right rear of the unit not working.

I have a Sharp XR-11xc and my bulb recently burned out. I ordered and replaced with a new lamp. It would turn on but no light would be projected. I read up on the subject and tried the reset of the lamp by...

I have the exact same problem. I've only reset the counter once though. It worked great at first, but seems to be getting worse. It's like it tries to start, just doesn't light up (maybe not warm enough???) then retries like 5 times until switching to the red light. Unplug and retry.... and eventually it does come on, and once on, all is ok. Is this just the projector trying to slowly 'break in' the new bulb since it has almost no hours?

Projector won't stay on

Most projectors have a filter that can be removed and cleaned. Perhaps it is clogged or you may need a new bulb.

red light indicates lamp is expired. even though you get temporary light, the lamp is shot. Try BULBMAN.COM for a new lamp.

PLV-Z1 no longer powering up - Ready light is green and the Lamp light is red

I have a Sanyo XU35. Mine was starting up and showed a picture for about 15 - 30 seconds then shutting down. My lamp warning light was not coming on. When I put it in for repairs it turned out to be the lamp that needed replacing. The technician said it is not uncomman for the lamp to be gone and the lamp warning light not to come on. I got my lamp on e-bay from ping_ngo for a great price.
