Half the screen dark but not black (UN75MU6300FXZC)
I just moved this to my house.
This TV was working 100% when we went to see it. We wrapped it in two moving blankets and padded it with couch cushions and moved it to our house - a 20 minute drive with minimal bumps. I deal with moving computer monitors frequently, so I was very gentle moving it into my house and mounting it.
Now half the screen is very dark. There are some mild horizontal lines and ghosting of the image as well. White things appear about 90% as expected, but mid-level to black-level parts of the image look as if someone turned the contrast up to 500%. It seems like I have the first three problems of this video.
There was one potential pressure point on the top of the TV where a strap was resting on it, but I really didn’t think it was too tight. I might have been wrong about that. If there was a pressure point up top, what issue could that create?
Any ideas?
Is dit een goede vraag?

Hey @jbarx19. Did you ever get to the bottom of this? The picture you posted showing your issue is exactly what mine looks like too. I have a UN75JU641DFXZA. The only difference is that I have a subcon PCB board in between my main board and the T-Con board. I tested the LED backlights-no prob with them. I replaced the T-Con board-no resolve there. I swapped/cleaned the ribbon cables from the T-con board to the TAB boards-no resolve either. Also seems unlikely that both right side TAB boards would go out simultaneously. Thoughts?

Had a local company quote on replacing the screen after trying everything I could find online. They said it would be $1200. Ended up just selling the TV for $100.

We have a samsung 85 inch and sure enough right at about 14 months the lower half of the screen was darker than the top. I was ready to bite the bullet and get a new TV and i saw this on youtube so i tried it and it worked! yay . . . so happy i don't have to spent another thousand dollars https://www.youtube.com/watch?v=T-y5pt06... if you don't watch the youtube just slap the back of your tv until it's fixed hahaha (that's what i did) i did have to find the right spot it only took 1 minute
