      Samsung UN70TU6980FXZA no sound no picture but does have backlights
      by stinger
      When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?

      Samsung UE50TU7000K backlights on, no picture or sound

      Plug in and backlights with Smart Tv powered by Tizen logo shows on screen
      then nothing, no stby led or response to remote, no sound from hdmi input.

      This has only 1 board, a 3in1_kant_su2.

      Try a usb stick with update firmware from Samsung and usb stick just flashes a couple of times, recognises usb, but thats it.

      Remove ribbon to panel, same results.

      I believe the leds are in an array of 3 x 12 @3v/led, going by what led sets are being sold for this tv on ebay and aliexpress.
      1 string of 12 leds, power supply in 84v, out...
