Chosen Solution

Hi, A few days ago I turned on the TV and faced a black background with a few green vertical lines. I did some research in internet and figured that It could be from T Con board or loose ribbons. I tried to pull out the ribbons and push them back in… Interestingly the black screen is gone now but still some black vertical lines and on the left side motion blur and in the middle faded color.

Before taking any action, I wanted to make sure whether it’s from T con board and replacing it would solve the problem. Thank you!

@x3rx3s this does not look like a T-con board error at all. This appears to be either a main board (most likely) or a power board issue. There is always a chance it’s the panel (unlikely) but check main board first.
