    TCL 43S405 No image

    Backlights do come one but I see no image on screen. If I remove the LEFT side TCON cable I get an image on the left side of the screen and I can see the menus working (right side appears black/dark grey with a few large lighter grey bars), removing the right side cable and I get a black screen. It appeared there was a damaged IC on the TCON so I replaced it but there was no change. Is the panel bad?

      I've had a few of these tvs that had this issue and was the panel on all of them. BUT I did see a TCL thread somewhere in here where maybe a guy was able to fix it by doing something specific. Don't remember thread though!

              LG 82UN8570AUD ~ TCON or PANEL?
              by kca
              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...

              TCL 50S535 bad tcon or panel issue?
              by x_orange90_x
              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...

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

              Samsung UE55JU6800K No Picture
              by Bloopeta
              Samsung UE55JU6800K with no image on screen.

              I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.

              Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
              I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
              Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.
