Samsung C32HG70 horizontal lines

I brought a Samsung C32HG70 a few days ago ( no power and when it was had the vertical lines until warmed up issue). I’ve manager to sort the power problem and also the vertical lines, however the panel has horizontal lines across the whole screen anybody have any ideas on what it might be? Included couple of pics running the Xbox Series X on it today.

I’ve had the back off the panel again and it seems to have a small 3mm split in one of the lvds that connects it on the lcd panel at the bottom, could this be causing the issue?

What function does rt6820a perform? I can't find the datasheet. In the LCD monitor, the chip heats up to 150 degrees and turns off. I can't find the reason.

Removing the resistors you showed was not a solution for me, but I discovered something new. The process I have done is available in the forum here. I had to use your photo, I didn't have a clearer photo, sorry.

@coys77 yes. Those are the ribbon cables coming of your driver boards. Any damage to those will manifest itself by errors on your display.

Those ribbon cables are connected via a special process (TAB) which makes it almost impossible for a DIY repair. You are most likely in need of a new panel.

Old question and this is just to clarify things.

Horizontal or a vertical lines on your LCD display usually indicates a bad LCD display (the panel itself has a very "partial", or "localized" failure). You can try with another screen to see if the issue insists. Or check out the post - How to Fix Vertical Lines on Monitor.

If it is the hardware problem, you’ll have to replace the screen.

I had the same problem, I removed 2 smd resistors and mine didn't resolve, there are still horizontal stripes at the bottom of the screen, of course until it warms up, then it's ok, maybe some idea
