Re: lg 42pc3d has sound no picture and no backlight

I know this is going back a while but cats, was there a specific place on the video board that you reheated, like the gpu? I have the same model tv with the same problem, sound/no picture. I ordered a new ysus and same result, all caps on the boards and all fuses are good. After I installed the new Ysus I had a quick blink of a picture and then no picture again.
