Problem with screen on nvidia tablet

Yesterday out of nowhere my nvidia shield tablets screen got a line across it, like dead pixels or something, I was reading a comic and suddenly I notices this line, rebooted and it appears on the boot screen also (the one thats shows nvidias logo and android).

Right across playstorehttp://imgur.com/ToOAxd8

Wanted to know if its fixable or the screen is just damaged with no repair except change the screen?

Thanks
