Screen Flickers with Horizontal and Vertical Lines
文本:
We bought a new TV back in December to replace this one, and until recently this TV was sitting unplugged in a hallway. After moving it upstairs and into its current location, the screen starts covered in horizontal and vertical lines, bleeding the colours on the screen. This occurs on every input and in the menus.
What's strange is that after several minutes, the picture will start to resolve properly, starting at the top and working its way down. During this time, there are no issues with audio and the menus are responsive to input with no freezing or delay. Below are some pictures taken specific timeframes after the TV has been turned on (put into Store Mode to demonstrate).
Just after turning on:

After about 2 minutes

After about 5 minutes
[image|3049823]
After about 7 minutes
[image|3049825]
After about 10 minutes

I have tried replacing the T-Con board and the ribbon cables between it and the display, but the issue remained the same after doing this. Same with reseating the LDVS connectors to the main board.
I'm trying to figure out if I need to replace the main board now, however after being burned on a T-con replacement that I apparently didn't need, I thought I would ask if anyone has seen anything like this before and could advise if it might be from some other, environmental issue or an issue with the screen itself. I've tried running it on and off the surge protector, on a different outlet in the room, and even with the nearby router turned off in case there was EM interference.
