Screen display problems with flickering horizontal lines

I've been having a problem with my screen for a few months now. When I open or close the display, or sometimes even just move it a little, gray, black and white lines flicker horizontally and randomly across the screen. Quite often the lines are fairly broad and sometimes are just faded strips of what was being displayed right before the flickering started.

For the moment i can make it stop by shifting the screen again or wiggling it back and forth until the flickering stops.

What is wrong with the display?

And is there a more permanent fix I could try?


Please help.

Thanks!



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