Why has The Flat Panel gone black?

The screen on my flat panel has gone black.

The computer itself is running, and I can get into it via AirPort and my laptop.

I can get into the Apps.& Docs., but would like to get the problem fixed.

Can you see a faint image on the screen when the G4 is running?

I understand you have completed a repair (guide) manual that will help in repairing my G4 Flat panel. Is it possible for me to get the guide?

Thanks, DickB

Hook it up to a external monitor to try to isolate the problem. It could be as simple as a PRAM battery or as complex as a failed GPU. You can also get to the hard drive by starting it up in "Target Mode" by connecting to another Mac via a firewire cable and starting the G4 up holding down the "T" key. Your hard drive icon should appear on the desktop of the other machine.

It's most likely a failed inverter though. Look closely at the screen and you should just be able to see the desktop etc in the darkness. The inverter should be behind the screen.
