8 No picture on the screen.
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.
Es esta una buena pregunta?

Well, after reading your reply, I was a bit reluctant to go ahead on the repair. However, I did the switching of the logic board today and got the machine to boot with a picture on the internal screen. Why the other logic board didn't work (since it worked with an external monitor) I don't know.
Anyway, this is the problem now, the trackpad is not working. I swapped a working track pad from my older 867 machine and installed it. It still didn't work. I have to use a mouse to point and click.
Any ideas on what I can do about fixing this issue?
