there are six red blink lights on the on/off switch when you plug it in i have the tv all disassembled when you disconnected the power supply from the main board the top to led light strips blink i replaced the power supply because i read it could be that because there is picture showing when you shine a flash light on the screen and there is sound so what do you think it could be led light strip, main board, or t con board i dont want to order wrong part again, thanks for any help
@shotbyninja If you disconnect the power board from the main board and your backlight still does not come on (and you already replaced the power supply) it is most likely the LED backlight strips.
