I have a Ibook G3 800mhz. that suddeltly would wan't to boot up and ther for show "Blackscreen". (or does it?) I thort it might was the logic board that was dead. (because http://www.apple.com/dk/support/ibook/faq/) But if i take a flashlight and pointet into the display i can see in the reflection that all is normal) But only if I boot up using Target Disk mode, the display tune on and i can see it ready for target disk mode. (that with the blue screen and rotating firewire symbol) so that is not the light in the display that is dead. so what now? www.ifixit.com/ is out of logic board for 800mhz g3..
