Light blue and white striped vertical lines instead of just white
My display has thin light blue and white striped vertical lines instead of just plain white.
It is not replicated on an external monitor though.
Sounds like a display or possibly a signal delivery error (cable) rather than the on board graphics processor.
After reading some of the replies to similar questions, I pressed each side of the iSight camera to no effect.
Is that a correct deduction?
