Hi
Hope someone can help with this, done hours on searching without success.
Just purchased (very cheaply) a Powerbook G4 15" Ali. Problem is the screen is dead, totally black, nothing. On start up I just get the one chime, as in normal boot noise.
I've done all the usual stuff with resets of Pram, PMU, start up pressing R etc etc. but still nothing. Reseated RAM, still nothing.
Have replaced hardrive with one from similar machine, nothing.
Have inserted OS X disc into drive, just spits it back out after about 15 seconds.
Obviously something not right with it, but not entirely sure what it could be and what to replace first. Could the logic board be faulty eventhough I can still manage to switch on, get a chime, insert disc etc? Inverter board has been suggested, not sure where this is located though, part of the logic board at all?? Could it be purely a failed screen?
At odds really as to how to attack this with regards of replacing what first.
Any ideas/solutions anyone?
Many thanks
Dex
