    LG 43UH6100-UH LCD TV - Horizontal banding and distortion

    I have a LG 43UH6100-UH LCD TV that is flickering and distorting the picture.

    From my limited research I have found the cause to be either the TCON board, loose ground or loose/bad cable.

    Here is a link to photos and video of the issue. https://photos.app.goo.gl/tvsm5Qpz7KLd8Aa16

    Has any one else seen this before. Thanks

    Looks like it could be a bad gate driver, try the "cut tape" method, sometime you have to play with the tape placement: https://www.youtube.com/watch?v=j7vl7-vZEL8

      nomoresonys,
      Thanks for the tip. It worked! I placed a very thin piece of tape on the left cable on the right side over the green stripe.

      I also referenced this video for any one else having the problem:
