What can cause colored vertical lines on laptop screen

My Toshiba Satellite A45 just started to cause problems on startup. The screen shows only small, colored horizontal lines during booting and after.

I can 'synchronize' the screen by moving its position back and forth or other random attempts of convincing the screen to play nice. Eventually it will.

What is the common cause of this failure, please?

I know the laptop is old and should be retired. But it is doing everything I need it to do very well. If it is simply a hardware problem that can be fixed, I will do so. I have access to a spare Satellite for parts.


The problem first appeared after one of the plastic hinge covers broke when the laptop was moved. I presume that the problem is caused by some connection between the computer base and the hinged screen.

Searched Toshiba repair sites. They have everything but suggestions on my specific problem.


Any ideas?

Please help.

Thanks!

I didn't find the right solution from the Internet.
