TV WILL NOT COME ON - TV Chirps when you plug it in
I bought this TV and late one night it went OUT. The picture had been intermittent before the TV "died".
I have heard that the problem is with the power supply on the circuit board.
How do I fix?

Re: TV WILL NOT COME ON - TV Chirps when you plug it in
The F25432 uses the CTC203 series chassis. The most common cause of the picture being intermittent is poor solder joints on the small coil connected to the base of the horizontal output transistor. These cracked solder joints will eventually cause the horizontal output transistor to short, and the power supply will "squeel" when plugged in. If you have experience working on TV's then you can try resoldering the joints on that coil and checking/replacing the horizontal output transistor. If you do not have experience working on TV's then allow a qualified tech to handle it for you.

Y Sustain board is bad. Replace the board will fix it. If you have bought the TV from Costco, then give them a call. Because the TV may still under warranty. I have repair a lot of P50 model lately and all of them still under warranty.
