Samsung UE50AU8072 all time rebooting, backlight ok. Maybe mainboard faulty?

The motherboard initially receives voltage for VGH, but it constantly reboots. When I remove the flex cable at the bottom, I hear normal sound, but there is no image on the screen and it is black on both sides. This time there is no voltage on VGH.

This is Samsungs method of telling you the panel has shorted. Replacing anything won't fix it.

Google fixing TV with tape, or if you are lucky check the buffer boards for shorted caps
