Vertical colored lines block out large portion of the screen (LCD)
I have an iBook G4 12" (actually my daughter's). Sometimes 80% of the screen gets blocked out by thick vertical lines. Applying pressure along the top of the LCD will sometimes get it to clear up. The problem doesn't seem to be related to temperature. Waking from sleep after coming out of her cold car, it immediately shows the lines.
I don't have the external monitor cable for this model so I can't test it with an external monitor.
I'm guessing it must be a loose connection or bad LCD panel. Before I go buying a new panel, does anyone have any experience with this symptom.
