    VERY BAD IDEA ! Call a REAL Technician if you care about your TV.

  • Joseph Nov 30, 2011

    Bad idea? Not even I was able to do this myself with the manual in about an hour and a half tops and have not had a single problem since. This is a website to help people hence the reason I provided some information about the topic, but you have some people like esnapp40 here who have nothing contribute other than complain and think they know more than people who have actually done this. This is supposed to be a helpful community so if you are not going to help or don't have any questions about it why are you even posting and being so negative? The price a technician will charge to solve this simple problem will cost you more than what the tv is worth it's a SIMPLE fix just looks complicated.

Which will help you to remove and clean these Air filters. Remember one thing remove lamp first then only remove the projection unit from the rear side.

Hi there,
here is a forum that discuss the same problem you have.

http://www.avsforum.com/avs-vb/archive/index.php/t-353230.html

Essentially, on the right side of the bulb compartment is the filter compartment. Open it from the front and you will see the filter. There is only one screw to undo.

Good luck

Air Filter Cleaning


Call the factory for an authorized servicer near you, your TV guy doesn't understand Panasonic...

If the lamp thermal sensor is active, the fans just keep running because it thinks the thing is hot (to save an expensive part from exploding). It does not give any error message.

Fan 1 is used for air filter detection. (It's essentially the same run-sensor type fan used in their stereos.) Fan 1 plug P2902 at the right side of the light engine board may not be making good contact or the fan is not running. The micro must get the proper feedback signal from that fan to keep it happy.

Good luck, Mark

Tepreture light comes on and OSD advising to clean air filter


if you take off the front panel to access the lamp for replacement. there should be the air filter near by that you can remove. Carefully clean it by blowing through it but use no liquids. If it is too clogged then filter replacement is probably needed. I think you have to get the filter with the new lamp otherwise.
