I have a 600 Mhz iBook G3 that works beautifully, except for the fact that the display just died. I believe that it is the backlighting behind the screen that has gone out. The screen looks black, but if you look at it closely while the machine is on you can very faintly see something on the screen. I have it hooked up to a monitor right now and it works fine that way. Does anyone know if the backlighting is fixable, and if so, is it worth the cost?
