Thanks in advance for any insight you might provide. I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new. That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts. Any suggestions? Applecare expired in Feb. Thanks!
