Hello Community,
I'm working on a Samsung UE70TU7020K.
It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.
I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential short is in the middle board which cannot be disconnected (as this is where the FPC connector is).
I appreciate it's unlikely to be a fix but would like to experiment with effective use of the tape method and identifying bad signal lines etc...
