1 SAMSUNG half screen black | Model: UN43NU6900B
The left half of the screen is black / pixelated. I’ve taken the back off and cleaned both ribbon cables with iso alcohol. I unplugged and replugged in most of the connections in the back to make sure they are snug. I’m not sure what to try to replace first, I would think the ribbon cables.
Here is what the display looks like from the front powered on
These are the ribbon cables at the bottom of the TV
This is the board both ribbon cables go to
There is one cable that goes from the green board to this board
This is the backside of the display powered on. I’m showing this because it looks like all the LEDs are on.
Questa è una buona domanda?

Cleaned and replaced both ribbon cables and whatever orange and white cable connects the green board to the power board. Problem still persists. I think the next step would be to replace the green board. Will update again once that happens.

ordered a new main board on ebay, but when it got here the display would just boot loop without ever turning on. I think because there's two versions of this TV; a DA01 and a BC02. you can find which version yours is looking at the label on the outside of your back cover. I think (I hope) the ebay seller sent me a DA01 board because when I plug my original board it, the display still shows split in half. I'm sending this board back and I ordered a BC02 board + power supply from ShopJimmy. Will update again once the new boar gets here later this week.

@abeforee You ordered the board with the black heat sinks, right(T-Con Board)?

@andrewsawesome I ordered the board in picture three (the one with HDMI, Coax, etc). I think the T Con board is the one at the very bottom between the speakers and I can not find out how to swap that, let alone get it out.

I replaced the main board, power board, ribbons, and cables that connect the two. TV is still split in half. The only things I haven't replaced are the speakers (shouldn't be a problem), IR receiver (I have a replacement but shouldn't be a problem), and the board at the bottom the two ribbon cables connect to. [side not I did not mention the panel because the general idea around the internet is that if you have to replace the panel you're better off buying a new TV]. If anyone knows how to access and replace the bottom most board that the two ribbon cables connect to, please chime in.
