        I've seen it explained many times but still not sure exactly how it works, I just consider it magic when it does work. some explanation there by a very wise man: https://www.youtube.com/watch?v=pfrRhw7-ZII

          I took the ribbon cables out from T-Con to Panel Boards to inspect them, I'm assuming the issue is related to the highlighted box in the attached image. I wonder how this could have happened as this TV has never been taken apart before.

            Eureka that's it, shit we should have checked that first, that's why I always try to do the basic simple inspections first, can save a shit-ton of chasing the wrong thing.

              you might be able to trim it off evenly and make it work or just get another cable.

                Tried trimming, with no luck. Going to order some new ones and come back with an update! Thanks for all your help.

                  No problem, I'm glad it was something easy to fix and not a shorted panel.

                    inspect the connector it came out of, make sure there's nothing wrong that will mess up the new one.
