Hello,

A month ago I had an issue with my LG 43LH541V LED TV. It wouldn't turn on, so I sent it to be repaired to an official LG repair shop, where they told me mainboard needed to be replaced. I got it back a month later (!!), and the picture is a mess. See below the difference between the TV and my PC monitor.

I tried every backlight/contrast/color setting, but there is no way to have the correct colors.

Can you tell me what can be the issue?

Thanks a lot in advance!
