    Samsung LA32R81BDX/XSA - Scrambled video

    About 9 months ago I had the lcd panel replaced under extended warranty. It was working perfectly until a week ago. Apart from the video, everything else is working. I can change input sources, and the sound works just fine. This is what the screen looks like. The colours on the screen change and roughly match the image I see on another tv tuned to the same channel.



    The power supply caps look ok. I've tried re-seating all the cables on the main board and t-con board, as well as re-soldering the lvds socket on the main board. From what I've read in this forum, my best guess is that I have a faulty t-con board. Before I order one on ebay, I wanted to double-check my diagnosis with the more knowledgable among you. What do you think?

    Thanks,
    Simon

      It looks like a t-con board problem. I'm assuming you've tried using the menus/volume control etc and they are scrambled too?

          Yes, the menus are scrambled too. A scrambled patch of blue appears whenever I change the volume. I'll order the t-con board tomorrow and let you know how it goes. Thanks for the quick response.

              LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
              by Hakuu
              Hi There,

              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

              Driving a Sharp TCON/panel with a universal main board
              by advant
              This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

              I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

              by m1ch43lzm
              Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
              Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

              Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
              by ohren
              I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

              I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

              The models launched in 2018 and 2019 respectively....
