I have a Powerbook G4 12" 1.5 GHz. There is no image on the screen. However, when I connect the device to an external monitor, I get the screen on the external monitor.
I wanted to know if it is the logic board's video that is bad. I heard that if you get video from an external device, it isn't the logic board.
I have acquired another logic board for this model and I am wondering if I should swap it or whether it is a waste of time.
thanks in advanced.
