I have a panny 44lcx65 and have gotten a warning message come up on the tv twice saying the "air filter needs cleaning"...Something like that and then shuts off automatically in about a minute. The manual says to "consult your nearest dealer" so I figure I'd ask all of you. I am sure this is something I can do. Maybe this is where the lamp is located? I can turn the tv back on and it works fine. Maybe something has plugged up the cooling fan for the lamp. (great idea sherlock!) Anyway, anyone have this happen and solution?
