Does it work when connecting to an AC adaptor?


IT only workds when I use the cinema display. The screen on the G4 doesn't go on even plugged in to power adapter. Took it to Apple and they think its the inverter but they can't fix it because it's too old. They gave me a place to have it repaired and it will cost $350 approx. to get it fixed.

You've stated that it does and does not work with a cinema display. If you can discern the desktop while holding a flashlight at an angle to the screen, it probably is the inverter. Here's the part you need if it is the inverter: G4 Aluminum 17" Display Inverter

Here's how to install it: PowerBook G4 Aluminum 17" 1-1.67 GHz Display Inverter Replacement
