Sounds like a plasma, or projection system. Find the fan inlet filter, remove the foam filter, and vacuum with a dust buster. You can use a can of compressed air to blow the filter clean, too.

My data projector eiki LC-Xb23 goes off without warning and the warning light is flashing


If the power light & warning light both flash red, this indicates that the projector is overheating. Once the projector has cooled down the warning light would continue to flash red and the power light would be solid red.

You should clean the air filters.

The filters are located on the underside. Disconnect all cables and invert. remove the 2 air filters located at the front and rear by pullingthe latches. They are both rectangular in shape.

Being very careful not to damage them, you should rinse the dust out and leave them to dry fully before replacing them in the projector.

This should cure the problem.

How do I clean air filter on the Panasonic PT-50LCX64?


I feel bad for you having such problems with the vendor and the technician too.
The location of that filter could be a small window in the back cover itself. could be a plastic window to the left side of the unit and is only a piece of plastic poliuretane kind of black sponge about 5 by 3 inches size .
What im interested telling you about the shut down condition and is maybe even most important than where is the air filter (who is one of the more than ten posibilities why the tv goes to shut down.
Note:
if the air filter is totally obstructed i would give one of ten probabities of suspicious why the tv shuts down:
first because the tv's air duct is not really isolated. The fan can eat air by any side of the air filter base as i said if the filter is totally obstructing which is really extreme. besides maybe the other 2 fans could help to cool down the unit in that case scenario. In my experience Most time the air filter holds tons of dust but is not totally obstructing the air passing, and really some other problems are in the set.

This is the really critical to know: if any of those fans stopped or maybe any sensor is overheated or the lamp is coming to dead or who knows.. a diagnosis is needed for this symptom really common in DLP technology.

Mitsubishi HC900 Projector shuts down after 5 minutes.


You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

Warning lights


Just so you know guys (and this procedure is not for the faint hearted!). I had the slow one second red warning light flash. I checked the bulb, which was find and I left it powered off for 48 hours. My projector is no longer under warranty and would have cost me over £300 to have it looked at. I ventured inside to inspect the boards, once I removed the main board to check the power supply I heard movement from one of the light ducts. It took me a while to removed enough to discover the fixing screw which holds the imaging cube in place (which is between the 3 light ducts and the projector lens) had come out (!?) and was rolling around inside the unit. This would also explain why sometimes I could not focus my unit properly. I remounted the imaging cube, put the whole thing back together and PRESTO! My projector is working again.
