I have a philips model #32pt81 s127 chasis# 32H800 7592 and have a couple problems with it. First problem is the sound from time to time would come and go and now has stopped working altogether. Not too much of an issue since i bought a tuner that runs sound from the cable box. However my big problem started last night. Was watching tv and the set clicked and abruptly shut off. Wouldn't turn on at first but finally did after leaving it off for a few minutes, however it will only work for a few minutes at a time before shutting off again. When it goes, the power completely goes. I gave the board a quick glance over to check the fuse and see if anything had a burnt smell but it all looks fine. I thought about replacing the whole chasis to solve both problems but can't locate one. Any suggestions on what's causing the problem and what parts need replacing?
