Black Screen - How to Diagnose Problem?
Just bought an old PowerBook 3400c for next to nothing. Unit is in great shape but has black screen. Chime on startup, hard drive spins up after about a 10 second pause. How can I determine if this is a VRAM problem on the motherboard, or a cable or screen problem?
