I just got a used Sharp Aquos LC-C3242U LCD, Cheap. When it powers on the screen powers up normally, then go's black in about 1 second. The audio still works. I tried to leave it unplugged for several days (I know this is more then necessary) and plug it back in. But I still get the same issue, so it was not a hard reset that it needed. I do hear a faint sound when I put my ear next to the back and turn it on. It sounds like a high pitched buzz, then quits when the screen go's black. I can't find a service manual for it, they said it is too new for them to be out yet, (I don't believe that).Any ideas on what the problem may be?
