rdklinc, Strip the iBook to the logic board level (now you get only the logic board), connect a known working DC in board, connect an external monitor, connect the AC adapter and power the logic board by tripping the two pins in the power switch connector. Check if you get the fashing question mark. If so connect an external firewire hard drive with compatible OS on it, try to boot tripping the two pins. If you still have the same blue screen issue then the logic board is bad.
