    Samsung TU8000, backlight and sound on, stuck in blue screen

    Hi everyone,

    I've got this Samsung here that would be stuck in a boot loop.
    After opening up and doing the tape block method, I was able to get it to turn on and play sound from the HDMI input, but with a blue screen.

    Does that mean there is another combination of pins that I need to block in order to get a picture, or is there something more serious, faulty mainboard or faulty panel?

    Thanks in advance

      Try these. A member here named Lotas posted it some time ago and it worked. Got great picture on half a screen. Was definitely a bad panel.

        Bootloop for Samsung usually means panel. With tape method, try more pins or less pins. If it stops the bootloop you are probably in the area. But generally not fixable. Can check the caps on the buffer boards for shorts and maybe get lucky. Also there are some tricks I've seen on here maybe someone can lead you to one that had potentially fixed this issue

          Samsung UN70NU6900F no picture and no sound
          by jchang
          Hi all

          I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



          Symptom:
          No picture no sound.
          When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
          No sound at all.



          What I tried:
          1. I tried unplugging the left or right ribbon...

          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...

          by ChaosLegionnaire
          so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

          Samsung NP750QFG-KA3DE does not turn on , Blue LED flashes 3 times
          by Egidio85
          Hi everyone, I have a Samsung NP750QFG-KA3DE , MainBoard VESTA3-15 BA92-24515A

          the battery is charged. pressing the power button the blue LED flashes 3 times and then stays blue. then the sequence repeats.
          the fan does not start.

          I noticed that I have no power on the processor and it does not heat up. could it depend on the bios?​

          any advice on what to check?
