Blue lines from top to bottom or no screen

[PwnsuxDNL]

Hello,

I am repairing a notebook of my neighbour, needed a new keyboard because fn key was stuck. So the only thing that has been changed was the keyboard and it works fine. 

2 days later I wanted to start the notebook and I didn't get/see the bios loadscreen, after that I do get the windows loading screen but with 2 or 3 blue lines from top to bottom (1 or 2 pixels wide).  Then I see windows desktop for like 1sec and the screen goes black (backlight still on and changeable). With an external screen it works fine in windows. GPU drivers are updated.

What could the problem be? Thanks in advance.

Thanks for your reply! but the problem is solved, took the screen apart and reseated the connector on the back of the led screen. Works great again.
