Try unplugging it for a period of time. And while you have it unplugged get a can of air and clean it out. When they are used for long periods of time and over time dust builds up and cause issues with all projectors. The require to be cleaned. I do mine about every month or so. More or less depends on use. Mine gets used everyday.

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.

Both the LAMP/COVER and FAN/TEMP indicator lights come on, not blinking

with both lights solid. according to the manual all it says is (there is an electrical failure inside the unit, please take to an authorized servicer). if you are able to do this yourself you will need the schematics and a voltmeter to start testing your voltages. your lamp is fine so dont waste your money replacing that anymore. if you would like the service manual send me an email to

Lights flashing

Replace the lamp. The lights flashing will also indicate what is wrong. Watch how they flash. Go to the manufacturers website and they way they are flashing indicates what is wrong (ex. 3 quick flashes, long continuous flashes...etc.) When you change the lamp reset the lamp counter in the menu and clean or replace the dust filters as well.

HI Clay,Is the green lamp light on fully ie is not flashing.?

There is no reset for overheat, if the problem is like blocked vents when it is rectified the only reset is power on/off and the fatal red or flashing orange error condition should go away

I have seen a simualr model that had the lamp cover open not showing an error but stopping it from working, but I dont think it was the exact same model but worth checking the cover is on properly

How many hours has the lamp done, do you have two of these machines?

If you do please swap lamps between the two again because this sounds like a lamp issue although we should be getting the error code unless the counter has been reset without changing the bulb for new..are you 100% sure your not using 2 dodgy bulbs and thats our issue, because Im suspect on these lamps unless of cause you can swap one into another and see it light, if that is the case then its has to be lamp contacts or a board fault but i need to know more exactly the deal with "known good lamp" and exact lights

Ensure we are fitting the lamp correctly and the contacts for the lamp are clean and fitting tight.Please ensure we have checked the silly things like lens cover, signal is being sent and pc aint asleep etc

It is 2.30 am in Oz, I'm off to bed but let me know some more info if you can and I have a dig deeper at work tommorrow for you and see if i can come up with some solution because all i can see it being now in my sleepy state is bulb, bulb contacts, lamp cover, mis reading lights, silly stuff or a board fault....

Cheers below is your user manual and the error light table

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.
