I got a PowerBook Titanium 1GHz via eBay. It’s got a black screen. Here are the symptoms:
Booting up works. Boot chime is working. It seems to run the OS just as normal, but the screen stays totally black.
I do not see a faint image on the screen.
Caps look and Num-LED, volume buttons and volume feedback works.
Sleep works - I can (invisibly) activate the panel with ctrl-eject and then the disk stops, but no sleeping LED. I can awake it by pressing a button.
The charger LED changes between orange and green as you would expect..
External Monitor via DVI doesn’t work.
I did the reset PRAM routine and reset the PMU.
It does run with only one RAM slot filled.
I didn’t disconnect the PRAM battery yet.
One cold think the graphic chip is the problem, but wouldn't the TiBook complain at startup about that?
Thanks for your help,
