A bug in my thinkpad display

Not sure why this is posted here vs. h/w support or stack exchange.

Well, I'd try to reseat the LCD cable at either end. Perhaps this is responsive to pressure on either bezel or main body side.

Short of knowing the previous history of this, there're quite a few possibilies, including a physical bug (like an ant or a centiped) tragically hacked an accidental connection inside the PC.
