No pic, fooling around I found if I disconnect half the tcon I get half a great working picture with sound. Once I hook it back up on tcon I have no pic, any ideas.

Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with... -
LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.
This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board... -
Hello everyone,
Thanks in advance for any help you can provide.
I have a Mi Curved Gaming Monitor 34". A few weeks ago it started to show (or not showing) horizontal lines. Of course, it's outside of the warranty period.
After some hours of reading and watching videos I disassembled the monitor and checked the ribbons that go from the TCON board to the panel PCB. If I disconnect the ribbon for the right side of the panel, the other half shows a perfect image. I ordered a "new" TCON, installed it and the issue persists so that tells me it must...
