Question about Philips 43PP9202 43" Rear Projection Television
Before I had a chance to order the stk392-1120s it got worse. I had the TV on and all was fine except I had turned the red down to nothing so the scenes were all green. I heard a strange very faint but high pitch sound. It was repeating like pulsing fo a second and stopping for a tenth of a second. The picture had gone off and that sound just started. I turn the set off and back on and all I get is that high frequency pulsing sound. Any ideas? I've watched it in "green" for a week now so I don't think I left anything loose inside. Thanks.
I would check the set for bad connections. The high pitched sound you are hearing is the high voltage section. If the convergence IC has completely failed, that can cause this as well. Try using STK392-150 or STK392-180. Either one will sub since they are pin compatible and they both can handle more power, thus should last longer. Also, make sure that you use plenty of the heatsink compound when mounting these.
