          There should be two flat white cable between the T-CON and the LCD PANEL, it looks like the left side cable may not be connected or the drive for that side is dead. See post 10 for the pictures of typical flat white ribbon cables.

                  Need help with this too. Don't have any technical knowledge and wondering if it's worth fixing

                      Samsung UN60JU6500, stripe on left side of screen
                      by valvashon
                      Friend sent me this picture of what their 60" Samsung from 2015 is doing. I didn't have any luck getting rid of a vertical stripe in another TV that developed one so I'm not too excited about trying to fix this one. It's mine for the asking; wish it had a dead power supply or bad backlights instead.

                      Is this most likely to be a connection at the circuit board or where the ribbon cable hits the screen itself?

                      Update: was just informed that this stripe comes and goes and has been doing this for a couple of months.

                      Thanks, Val

                      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...

                      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...

                      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....
