Re: sharp aquos lc52d64u no display or sound

I also have an LC-52D64U and I get a picture for about 2 seconds then backlight goes out and power and OPC light come on steady. If I leave it the set shuts off but if I hit power off then on it does the same thing. I replaced the power board (it was cheap) and same thing. I do get a high pitched whine from the #3 inverter, would you suspect that is the problem?
