Faulty LCD cable, LCD or logic board seem most likely.

Does the symptom change if you move the screen on it's hinge? Or does it get worse with time/temperature?

Known issue with video chip

Sounds like the solder is failing - could extend the use of it for a while with re-balling or the fire fix.

Good Luck,
