Blank blue screen always appears after Apple icon

Texte:

Hi!  I often get iBook G4s that can go into the option menu and target mode, but when you select a volume to boot from, or let them boot to the hard drive, they go to a blank light blue screen and then stall.  This happens immediately after the Apple icon screen.  The Apple icon screen will disappear after a while, there will be a sort of a flash of a screen refresh, and then the laptop will sit on a blank blue screen, and that's it.  I've tried all the typical stuff -- removed the RAM and Airport, done PRAM/PMU resets, swapped the hard drive, tried booting to an external drive, etc.  It doesn't matter if you try to boot to the internal drive, external drive, or restore media.

I can only assume it's a logic board issue, because I've tried everything I can think of.  There are a lot of machines like this, and it's frustrating to let them go, because they seem like they are close to working, and it feels like I'm missing something.

Any ideas?

Thanks!
