I have a KP43T75 that has been working great for about 4 years now unti
this week. I noticed a little bit of color distortion every once i
awhile for a few days and then last night it just buzzed for a coupl
seconds and then shut off. It would not turn on at all. I cycled th
power and now it clicks like it will turn on but then the STANDBY ligh
just blinks 4 times. I've talked to a couple repair shops and they sa
its most likely the power supply, but they want $250-$450 to repair it
Any tips on doing it myself. I imagine its just some transisters an
what not that need to be replaced on the board. I'm sure I could do i
myself, but I just need some pointers. Let me know.

Thanks,
Mat
