    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.

            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.
