Question about Philips 50P8341 50" Rear Projection Television
I posted this earlier but it applies in this case so here goes,
The chirping sound is either a shorted Horizontal Output Transistor (HOT) / Power FET (whichever one is used in this case) or the IHVT (Flyback Transformer) has developed a short in its windings. In ether case both components will have to be replaced. I would suggest you have a qualified TV technician come over and troubleshoot the problem and give you an estimate on the repair.
However, if you are doing this repair yourself take into mind that the HOT and the IHVT (flyback) are in a series circuit configuration and if the Flyback is bad I would change out the HOT also, and vice verse.
I hope this helps,
