Model: un55ks9500 TV stuck in power on loop, never fully powers on all I get I’d backlights before it restarts. I’ve changed the power and main boards. Unplugged for hours, days and weeks. Tried different power cables and outlets. Stumped. Please help! Thanks in advance!
@chrisbhughes disconnect the power board from the main board and see if your backlight comes on and stays on. Also post some good pictures of all of your board with your question. That way we can see what you see. It is possible that this is a backlight array issue as well as a panel issue
