While watching my Samsung LED Smart TV tonight I noticed a problem that seemed to come out of the blue. There is a line running across the entire length of the screen, about an inch down from the top, and the space between the line and the top of the screen looks like it has a shadow over it, and part of it is cut off. Meanwhile, what should be being displayed across the very top of the screen is being displayed across the bottom of it instead. It is happening on every input source, and even the menu is affected by it when it's on the screen. Has anyone heard of anything like this, or maybe knows what exactly the issue is?
