I'm having an issue with screen with a line appearing all the way across the top and a small one in the bottom left corner. I've attached some photos to show you what i'm talking about.

Don't have an external screen, but connected to my TV and didn't appear there. Also did an LCD Bist Test and nothing was on there either.

I had the same issue nearly two years ago with the a line running across the bottom and ending up needing the screen replaced, really hoping that isn't the case again.
