Hello all my PowerPC brethren. I have a project from a family member here. I was given an iMac G5. It has a 1.6ghz procesor, 512mb of ram, an 80gb HD and a Combo drive. It used to be an education machine at a college before he bought it, and now I'm its new caretaker. The machine makes the boot chime and will accept and eject CDs, but the screen displays nothing. I was wondering what could cause this, and how much should I expect to spend on repairs? Is there a checklist of things I can look for? I don't want to go crazy on a broken PowerPC, but if I can get it working for cheap, it would be a great work computer.
