Question about Philips 43PP9202 43" Rear Projection Television
I have had my 43PP9202 for a little over three years. This past October I was experiencing red and green hour glass shapes across the screen when I would first turn it on. If I shut it off and turned it back on, the distortion would disappear. After two weeks of this problem, the picture would stay distorted no matter how many times you cut it off and then back on. I called in a repairman who replaced two convergence ICs (STK392-110). Since then I have had no more problems with the set at all. Until the other morning I woke and turned the set on to discover that all too familar red and green hourglass stretched across the screen again. This time, however, it did not matter how many times I turned the set off and on again, the hourglass was still there. Frustrated at this, I left the set on and went into the other room and was simply listening to the program that I could not see. Imagine my surprise when I went back into the room and there was no picture but the sound was perfectly coming through the surround sound receiver I have the set hooked up to. I did not think at the time to check and see if sound was coming out of the actual television speaker itself. I unhooked everything from the set and moved it from the stand it sits on to make it easily accessible and when I plugged it again I get no sound, no picture and a clicking sound which appears to be coming from the back at the bottom of the set. Any direction you could point me in that does not involve another repairman to come to my house so I can pretty much pay for his vacation would be extremely appreciated (by my eyes which are strained by now watching a 19 inch set). I have two friends who are electronical inclined are offering to help me as long as we have some sort of direction to start in. Thank you so much!
You idiots **** me off. STK394-160's are for Hitachi only. Cary

I had a similar problem recently. the ic's eventually went completely bad, and caused a short which made the tv beep at me when i tried to turn it on. replacing the ic's fixed everything, so it is very likely that the ic's are responsible for the short. as for the STK394-160E's, you can find them here. didn't have any luck finding them on ebay, but who knows, you might get lucky.

Sounds like maybe the IC's have shorted and are keeping your power supply from starting up, (possibly the supply is now bad), the amps that I use now are stk394-160e's to replace the stk392-110's, they are rated for higher frequency of the HD tvs than the originals and hold up better. The original tech may have missed a bad resistor as well, I would definitly call them back as it may be under warranty (90 day warranty or 30 day are typical)
