    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:

          Here is the updated screen.

                      Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
                      by Ihandyrepair
                      Hi guys

                      I just started fixing 4k TV few months ago. so I am still learning a lot
                      I got this tv from friend complaint is ghosting or horizontal lines on image.

                      never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                      then it started to show the ghosting white image.
                      I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                      it has 3 thin small boards at the bottom of the...

                      IBM LTO 7 Tape Drive - Dust Sensors??
                      by RetroComputingGrotto
                      I have a Quantum SuperLoader robotic tape library that uses an IBM LTO 7 tape drive which is constantly complaining that it needs cleaning. If you insert a cleaning tape, it performs the clean and resets the cleaning counter to 0 hours. It should only require cleaning every 50 or so working hours but after as little as just 1 hours use it requests cleaning. We've purchased a new cleaning tape along with new LTO backup tapes but that has not resolved the problem.

                      I have taken the library apart and can see no noticeable signs of dust inside. I have removed the tape drive from the...

                      Problem

                      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                      LG 75UN8570AUD panel issue fixed with tape.
                      by triplefour
                      I've been seeing a lot of the new TVs (samsung and LG only i think) maybe 1-2 years old suffering from sudden panel death and have been over 50% successful bringing them at least most of the way back to functionality if not all the way, with the tape masking of the LVDS pins method.
                      add this one to the list. the issue was on the left side of the panel and i ended up blocking just 3 pins on the connector that joins the two panel boards that make up the left side of the panel (it has 4 boards total) i didnt get the picture back to 100% perfect. i spent hours fiddling with which pins to block...
