How do I fix evenly spaced vertical lines across entire screen?
I have a 55” LG tv and it has evenly spaced vertical lines across the whole screen. They are static-y in appearance, so it looks like the whole screen went through a faulty printer that skipped ink or something. The lines only appear on images from the input, and not anything Menu related to the tv (No Input message, Menu options, Logo, etc.) I have replaced the T con board and that did not fix the issue. I have even baked the main board in the oven to see if that would help, but did not. I have taken each ribbon out and wiped the connections to them. I am not sure where to go from here.
