Solved! Vertical coloured lines?

[callumatic]

My V17 Nitro has vertical lines of different colours on the left side. When I push down on the edge of the screen it gets worse, when I let go the usual lines stay. They randomly appeared when I was fixing the rear screen 'case' as the little plastic thing that holds it together broke. I have already turned it off and on with no luck.

It sounds like the display may have gotten damaged when you were doing the other work.
