This question was asked before :) The most common issue for this model is the lamp.If you never replaced the lamp this is the best place to start.They usually last 2-4 years. The original one in the TV can last up to 7 years.

Panasonic HDTV are some of the best. It is very rare when a part in this TV set goes out. The most common issue is the lamp. A ballast board may also go bad with time but it is very unlikely.If you never replaced the lamp before that is the first place to start or if its around 3 years old.

the filter will need to be cleaned and if the set still shuts down then I would suspect the fan may need to be cleaned and possibly replaced.

Lamp, Ballast or power supply are first things to inspect.

I had the same problem with a Toshiba DLP rear projection. It sounds like the ballast. I replaced mine myself and now it works perfectly. Cost was about $160-ish. Easy job thanks to diagrams and photos online.

Not easy and rarely needed.Let me know the issue and I may be able to advise you
