Line has progressively gotten worse, you can only see it if theres a light picture showing. I haven't had the tv very long. Going on second year. I own a “40.

Is this something I can fix or just deal with until the screen goes out?

Cara Church that definitely looks like a bad panel. Possibly the diffuser sheets but the only way to find out would be to dismantle the panel. At this point I would ride it out but you could consider removing the back cover from your TV and getting the manufacturer name and panel number from the label glued to the panel. See if you can source a new panel etc. based on that. Let us know what you find.
