I am assuming this is a bad LCD panel any thoughts?

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...03-15-2024, 03:01 PM -
I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.
I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying... -
Hello community. I've got an ASUS VA27EHE with a Panda LC270lf1l01 panel that started to behave strangely. A bit of intro:
If you power on the monitor without any inputs it turns on, displays the ASUS logo, shows no signal and goes into standby normally.

And after the system loads it almost always works properly, lol. On some rare occasions a part in the top of the monitor is being distorted...03-26-2025, 03:42 AM -
Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.
The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly... -
Hello!
I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.
Problem
My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.
(See Attachment 1)
Self Diagnosing
After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...
