Does not turn on, not even on standby inoperative!Power supply, for testing, just remove the cable from the cnm803, the TV has to turn on the backlight without the main board, otherwise it's not the same power supply.Replace the same! or make the repair, in my case it was short and open protection component. fuse fp801s, and short qp801s and cp810s blown.JOHN GAMES

TV turning off by itself and sometimes with a black background blurred with redI resoldered the power supply, checked the electrolytics, washed the board with teener, but it didn't solve the problem.I saw sticky oil on the signal plate above and below the plate, I removed the square wafer of thermally conductive silicone rubber, I washed the entire plate, I cleaned it well, I dried it with a hairdryer, I adapted it with insulation in its place, the aluminum heatsink with thermal paste, I glued it only to the corners of the insulation and the heatsink, the problem is goneTulio Moreira
