Alright, so today I got a call from a friend saying that their iBook G4 won't turn on properly. I grabbed a display and headed down. Using an adapter, I got the display connected and it worked. The entire display was mirrored. But the internal display stays gray. It bongs, CD drive spins up, and boots to the desktop with an external display but not the internal. What could be going on? Is the LCD cracked, backlight gone, cable loose? I'm absolutely stumped. Any ideas? :-/
