What could cause screen distortion?
My Powerbook screen will unpredictably be distorted to the point where it is unusable. Here's a video of it http://www.youtube.com/watch?v=hmkZFEtae...
The distortion does not show up on an external screen or screenshot, is not affected by moving the screen, but can be cleared with a whack on the bottom of the laptop.
Is dit een goede vraag?
