    Samsung HG55EB690QB No backlight until disconnecting mb

    Tv has stb–light (flashes x6) but no backlight. When disconnecting the cable between psb and mb backlight comes on, but no picture.

    I had a smaller tv with the exact same problem and mb. I got hold of one mb on eBay and that fixed the problem. But now i can't find one.

    Someone with any thoughts?

      Samsung QE82Q70RAT no backlight
      by sansanpartida
      Hi everyone!

      Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.

      My issue: No backlight.

      Model: QE82Q70RAT
      Type No: QE82Q70RAT

      The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.

      So hopefully, I can fix this cheaper.

      Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
      by howardc64
      • Prior owner tried a replacement main board. No difference.
      • Samsung 2x red blinking standby LED = panel fault
      • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
      • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
      • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

      Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
      by Ierwin
      Hello everyone,
      Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
      The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
      He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
      I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
      Anyway I still fully expect that there has been something seriously damaged...
