TV won't turn on and the power LED blinks twice
It's a Samsung UE65TU6905.
PSU is OK, mainPCB seems responive. When disconneting flatcables from mainPCB to panel, Backlight stays on. When disconnecting 1/4 of the panel (flatcable between drivercards on the panel) backlight stays on. Sound is on. No picture.
Rob Schoovaerts we are getting a bit ahead of ourselves. Keep it all connected or reconnect. After that, only disconnect the main board from the power board. What do you get? Post some GOOD pictures of all of your boards with your QUESTION. that way we can see what you see. 在已经存在的问题里加入图片
