    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

          Samsung QE50Q60TA rebooting
          by plytek
          Hi all.

          I'm trying to fix my Samsung QE50Q60TA TV.
          IT's rebooting every few seconds.
          I have done some tests and it looks like it stops rebooting when I tape pin 46 (I thinks it's FB_1) on the ribbon tape that connects two boards atteched to screen, but nothing is visible, just backlight is solid and I can hear sound. Taping over other pins doesn't work.
          Have also soldered two pins on the motherboard to check if I can get an image on the rights side of the tv, but it keeps rebooting.
          Can anyone suggest what I can test and do to get it working again please?...
