Black vertical shadow line in middle of screen

[Nb14]

I have a 6" wide line down the middle of my 55" sky glass. It's like a shadow and more visible on some content than others

Line is on the left side of the screen

@Nb14 and @Lindsay0509 .  I had a vertical 2 inch wide line running through my Glass Screen and I unplugged the TV overnight and the next morning when I plugged it back in again the line had disappeared and thankfully it never returned.  It's worth a try but if it doesn't fix the issue or if it does but the line returns I would call Sky for some more troubleshooting and possibly a replacement Glass TV.
