    Samsung LE40F86BD - Bad t-con board?

    Hello

    I just finished replacing power supply capacitors on my TV, but when I turned it on the screen looks like this.



    Does this look like a bad T-con board to you?

    Thanks!

          Panel Gate drive issue causing doubling images. Taped off method may solve the issue.

              I agree with Budm, there are video's on youtube that address this issue.

                      Thanks for the video link, it was very helpful! You guys were correct. I opened the tv and managed to locate the panel gate drive. No need for any tape, just unplugged it and plugged it back in and now the tv image is perfect!

                      Thanks a lot!

                          Ok, thinking you just had a bad/dirty connection if you just had to re-seated the ribbon cable.

                              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.

                              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.

                              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...

                              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....
