    Samsung UA46B6000VF LCD Picture problem

    Hi all,

    This TV is 5 years old and has some picture problems (lines) which I am hoping to solve. Attached are some pics of the problem(s). I have labelled them with a basic description as the problem(s) can vary a bit from initial turn on and after warmup. This warmup behaviour is very repeatable.

    I have had the back off and had a good look at all the board components, but cannot see anything suspicious. I have reseated all ribbon cables and cannot get the problem to go away. I am thinking it could be either a bad LCD panel or possibly a bad T-con board. Before I purchase another T-con, I was hoping to get some expert opinions from you guys.

    Cheers
    Dave (Sydney)

      I saw it's a bad panel but you could try reseating the Tcon connections.

          Samsung UN55MU8000 - Backlight But No Picture Problem
          by KYBOSH
          Hello all

          I pick this up free as a repair project for the holidays.
          The original symptom was power cycling after 3-4 seconds with a single red light flash.

          To remedy this I went through and unplugged each component 1x1 and discovered that when the FFC cables were disconnected the backlights stayed on and the TV did not reboot.

          I tried remove one or the other to see which side of the display was causing the issue (expecting to see half a picture to show) but didn't see anything. But the boot loop only appears when the top FFC cable (right side...

          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
          by Mgiffune
          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

          I ordered a supposedly ‘new' Tcon board this time, and          ...

          Samsung QN75Q6DRA, No Picture, Has BL, and Sound
          by Dodgethis
          Hello all,

          This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
