LG TV Flickering - 49UF6430-UB.AUSYLJR

Hello,

I have a LG 49UF6430-UB.AUSYLJR for 2 years now. This past week it started flickering the left half of the panel.

My impression, is that it seems the Smart TV overlay is flickering, not the whole panel. I say this, because when it's flickering, I can't access Input, Options, or any Smart Apps.

Sometimes it stops, and when it does, i can access all menus perfectly.

There is someone in Youtube with what seems to be the exact same issue as mine. It seems like he solved it replacing the main board.

Have anyone seen a similar issue? I'd like to try to confirm before buying the main board.
