Here is your $75 service fee for free:
My Panasonic PT-52LCX16 from Costco (July 2006) showed the On Screen Display: Air Filter needs cleaning and the TV will shut down in 1 minute.

After searching the web for hours and amazed that I could not find the solution, I call the local Panasonic repair shop and Matt came out on the service call.

Matt has been doing this for twenty years and I was getting some on-the-job training because I was ticked that I could not fix this myself.

Here is your information you wanted:
Turn your TV OFF
1. Remove the grill cover in front. Gently pull on the sides and then the middle and the grill should come out.
2. You will see a door with a round door knob (this door is for the lamp), turn the knob and the door will remove.
Put the door back on and turn the knob
This will clear your On Screen Display message when you turn your TV back on.

Note 1: There is NO Air Filter on this model!
Note 2: If you do NOT put the door back on and yurn the knob you can not turn yout TV back on. Good safety feature!
Note 3: There is a firmware revision that you can download on an SD disk and place this into the TV and it should update the TV to show ??????
Matt told me it should give you a warning that you need to replace your LAMP.
Note 4: This model does NOT have a menu to see how many hours are on the lamp and how many times the TV has been turned on/off.

I have not replaced the lamp yet and I have not updated the firmware. My plans are to order a new lamp (this lamp is # TY-LA1001, $233 - $275), replace the lamp and then update the firmware.

Matt told me what usually goes out is the Light Engine and that's about $1000 with the service call. Buy a new TV at that price.

I did not by the extended warrenty on this TV and Matt said if your TV costs more than $2500 or more he would recommed it because some parts are just cost so much and your are out of luck when some thing goes out.

I had the same problem and the stupid tv would shut off after 1 minute. We opened the silver front panel , took the bulb out cleaned it, took the cover off the grey box to the right and very carefully vaccumed the filter and wiped it off with a microfiber cloth. It works great now!!! Make sure you unplug your tv before messing with it.
