You can not install anything that is not specified by manufacturer. All you can do - make sure your TV have enough "breathing" room on it's back , top and sides. All Plasma Panels produce a lot of heat - it's "normal" operation. If you still unhappy with it you can put regular household fan on the back of the TV. I doubt that it would make any difference though.
What a ridiculous blanket statement ("You can not install anything that is not specified by manufacturer"). If the plasma TV is out of warranty, cooling fans can and have indeed been installed in plasma TVs. Anyone with the skills to work on electronics should be able to do it as long as they are aware of the high voltage present in the TV. I installed several cooling fans on the inside of the perforated metal back panel of my 50" plasma TV, specifically over the buffer boards and the YSUS board.

Hell add a 20"box fan and run it behind just flush to the ventilation slots while watching it in my opinyon it preserves it longer and keeps it cooler, not a lot of electricity and keeps the screen cool too ...plasmas are cool just take of them and remember heat is the enemy ....oh yeh screw wall mounting fastest way a plasma can fail
Run it with the back open and see which parts get the hottest, add some heatsinks to them. alternatively wire in a computer fan with a small hole cut in the back panel. you could run it off a 9v battery.
My Panasonic is 7-8 yrs old now. I simply took some painters tape and a few scrape pieces of cardboard and made "cooling fins." Taped them strategically around the vents. Cheap, simple and effective.

Panasonic said 104* F was their upper limit. Mine regularly showed 120* to 136* and the power pack burned out. They had no fix nor recommendations. Fan behind or on the floor blowing up were too noisy. CPU fans require a method to narrow the air intake and should blow the air up and out to get rid of heat buildup. No way to attach with screws but a plastic zip tie could work. Also no way to wire a fan to the on/off system without voiding the warranty.
