Hey guys, I have a LG 49LF6310 which is 1.5 years old. All of a sudden my TV started flickering while accessing menu or while using a thing related to the os but it works fine while watching movies or TV. Please help. I have attached a photo where you can see the boxy flickering why in settings menu. It disappears when I exit it. It looks like a Software side problem but i cant seem to figure out what the problem is. https://imgur.com/a/Yzq9Jw0 The Images are on the Link above. Please help.
