My panasonic PT-52LCX35 has a blue screen and says to clean the air filter and it is shutting down in one minute. The red light indicator is blinking 5 times every 5 seconds. Where is the filter located? The owners manual does not show it. Thanks!
Our TV did the same thing. After calling numerous repair shops, and hearing there was no such thing as an air filter, or they had never heard of one, I decided to try to fix it using a suggestion I read on-line.After disconnecting from all power, take off the back panel, and using some compressed air, blow out all of the dust that has accumulated. I had to use a box fan just to blow the dust out of the house! Afterwards replace the back cover and it should be good again. Hope this helps!

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.
I think i have found the fix
I kind of feel dumb for all the mess i have gone though to get here and if im right it is soo simple
Dont buy a panasonic haha jk
Directily under the panasonic logo is ur air filter
Pull off you speaker cover at the bottom of ur tv
Then directily under that log is a pannel with two screws
Take that off
now take can air and blow out the foam u see on your optical lense
top and bottom
be careful the optical lense cost $800 so dont turn ur caned air upside down
this is what i finaly did and so far so good
it has taken me over a month of taking my tv apart every night to see what was right infront of my face i hope this helps everone
