There are indeed 2 air filters on the light engine. To clean these, it is necessary to open up the television's back lower panel, remove an electrical component, then slide out the projection unit (you must be very careful - this is over $600 to replace if you break it). The air filters are pretty easy to clean...I used gentle strokes from a soft bristle hobby paintbrush and blowing (I wouldn't recommend using a can of compressed air for this...these filters are somewhat fragile). Dust out the rest of the unit pretty good (use EXTREME caution when doing this). Then put everything back together, and then you have to go through the re-alignment procedure. You can obtain the technical service manual on the Internet...sorry, but I can't help you find it...I am not sure about the legal/copyright ramifications of distributing the manual w/o Panasonic's permission...but its out there...Google is your friend. I would NOT attempt this repair without this manual...it contains crucial diagrams, and "gotcha" warnings (like what order to tighten screws for example). This isn't a hard repair if you just take the time to prepare, move slowly and methodically, and don't be in a rush. Good Luck!

I did the following 'press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual)"
Will in the service screen I selected the number of hours of the lamp with the down arrows and the action buttons. Then I simply pressed and held the "down volume button" on the remote until the number of hours was 0. Then I turned the TV off, then back on and the message was gone. This worked for me.

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.
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.
