Question about Apple iBook G4 Mac Notebook
I'm having trouble with my iBook G4, 14" 1.33GHz model. I'm running Leopard, the latest version. The screen broke not to long ago so i bought a G3 14" screen for my iBook. I know the cables are not the same. The thing is the computer used to work when plugged on an external monitor, now i can't seem to get that to work anymore. I'm very certain this isn't a logic board problem as that's never stopped the iBook from working on an external monitor in my experience. Both, the LCD and external monitors show a sign of signal when the computer is turned on but then nothing more, the screen stays black. I have tried flashing some light through the screen to see if it's the backlight but it isn't the case. What could be wrong here?
If you are still faced with this problem.....
Possibly the video card has gone in the unit. The original screen on the laptop may have had an blown inverter which would not stop the funcioning of the external display. However for the external disply to stop working would suggest the video card. Before going this far have you checked to see if there is power to the external monitor? Have you tried the monitor on another computer? If the monitor works with another computer you can be certain there is more wrong with your poor old iBook. You will need to take it in to be looked at.
Hope this helps.
