    Samsung LN52A650A1FXZA T-Con board issues?

    Loops with the startup sound and a bad image.

    https://www.youtube.com/watch?v=dTLTGaJhxQ0

    We changed the behavior by disconnecting the cable from the T-Con board. Played startup sound and no image but relay didn't click.

    Also noticed a little bit of a viscous fluid on the chips. No other apparent liquid damage on the other boards. Caps on power board are not bulged and some use 820uF. All are by SamYoung.

    Will likely get a replacement T-Con board.

    What happened to the (apparently bad) T-Con board?

    Try hitting mainboard with heat. I have one here that does that and after like 20 successful attempts of reboot ing the picture finally comes in clear.
    Did I leave the soldering iron on?

            Focusing on the mainboard now with more pictures. Model number reads BN41-00972C and there are parts with the designation "DEx AS7". I don't know their exact specs.

            I found C131 but I can't find C102

            Would love to apply heat but not sure where to target

            Will also consider replacing certain parts but don't know exact specs, yet.

            Thanks for reading

              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.

              More Details

              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              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...

              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....
