Line across display (1 Viewer)

[Dave Moritz]

I have a 43" LG model 43UJ6300 4K display that I am using for my computer and recently it has developed a line across the display. Am wondering if anyone else here has had this issue regardless of brand and how much it cost to get it repaired since mine was purchased 12/17/17 and is no longer under warranty.

That looks like a bad display driver board, which you can buy relatively cheap online if you're handy enough to open it up and replace: See on Amazon

Thank you Dave

Change the aspect ratio and see if the line moves or stays in the same spot.
If the line moves it is most likely either the main board or the T-Con board. If the line stays in the same spot through all the aspect ratio changes and on all the inputs, it is in the panel and probably not worth fixing.
