My problem is that my Philips 42FD9932 will shut off after a few minutes use and a the led will be red. I cleaned the fan grilles on top of the unit and put a large muffin fan (like from a computer) on the top where the grilles are to help suck air through. It does not shut off now. I am working on a permanant fix like a permanant fan or actually determining what circuit is overheating. The units fan work. If your unit won't turn on and gives you a flashing red led, unplug the power and wait 30 seconds then plug it back in. It should work.

I found my problem via local TV repair shop, and verified the probable cause by Philips beforehand. The problem is a failed Power Supply unit. And, Philips acknowledged that they have been failing after about 2 - 3 years!!! For a TV that originally cost 5+ figures, that sucks! Philips put a "lemon" part into this model TV.

I also have this problem with this unit. However, mine shuts off after various amounts of time.....sometimes hours, sometimes in less than a minute! Really annoying!! Does anyone have an idea? I've read about possible fan or infrared ray problems causing this unwanted shutdown.
