Plasma won't stay on red light flashes and shuts unit off

I have a Philips 42fd9932 42 in plasma. It is about 3 or 4 years old. It is shutting itself off. The green led light that is on when the unit is on will flash to red and then it just shuts down. Is this a part or is it overheating? Any suggestions? Thanks.

I had similar problem with 42fd9932, run for a few secs or minutes, shutdown and flash red led for ever. Fans in this unit were not causing shutdown although I could stop one and get the red led flashing thing.
Replace c2212 100uf, c2508 4.7uf changed to 10uf, c2664 100uf. I also added clip on heatsink to U7203 8.5v TO-220 case regulator( next to c2212) and a drop of oil to each fan(poked a hole through label center). Something else I did was add a 47 ohm 5w in parallel with fan ps 100 ohm 5 w resistor.
These parts are all located on the two power supply boards. Use Caution 380V is present on these boards. Allow a few min for caps to discharge.

I had the same problem w/ my 42PF9630A and I downloaded software updates from Philips.com for my unit. You need a portable memory (I used my daughter's PSP) to download the file to. I then plugged the PSP into the USB port on the side of plasma and the TV did the rest. It no longer shuts off. There are specific directions on the website.

The fans are visible in the back and they can be cleaned with compressed air with no moisture built up in the hose line,We don't want to spray water in the fans.Is the only thing you can try and the unit's back does not have to be removed.If this does not solve your problem you might need the help of a servicer.Let Us know how it goes or if you need more information.

I have a phillips 42fd9954 17s. when i turn it on the green light tuns on for like 6 seconds then fades . then nothing. no sound no picture. any idea. i am using a comp cord. had no cord when i got it

if you use vga input and there is no signal the tv shuts down in few second. It will wake up again if you provide vga signal or cycle it on off again. Change input to component or s-video and tv should stay on. On the other hand, this model has known problem with bad power supply unit but usually red light flashing when tv shuts down in that case.
