Hello,

 

I seem to have semi-killed my Powerbook G4, 17", 1.5GHz during a hardware repair and need to know what part to replace.

 

After pressing the power button, I get the usual chime, and the HD spins up. The optical drive does not make the usual noise, and the screen remains totally black (no back light issue).

 

Before that, I had a brief phase in which everything worked just fine when the case was fit loosely but not screwed fast. Once the screws were in, startup stopped at the grey screen with the apple, spinner moving forever.

 

I have reset the PMU and the PRAM, to no avail, so I guess I killed some hardware part. But which part would that be and what would it cost to replace it?

 

Thanks,

PowerBook, Mac OS X (10.5.8), G4 17" 1.5GHz
