RE: [Thinkpad] Thinkpad A31p Screen Corruption - an update

I, too, have this problem. I'm banging the back of the case to get it
to stop! (not too hard, but a bit comical!)

I've taken the 2 screws out of the screen frame and removed the frame
and tried to find something to reseat. After doing this, it calmed down
but still rears its ugly head if I close/adjust the screen while holding
the corners.

I downloaded the service manual which shows how to disassemble the
screen but haven't had the time to try it.

I, too, strongly suspect a loose seating of the video cable on one end.
