PowerBook G4 15" LCD display goes black
I have the same model and a few weeks ago started to have EXACTLY the same problem. Video only works on external monitor.
Any advice on how to solve the problem will be appreciated. Dan

If you look closely, do you see any images at all, or does the screen appear to be entirely off?
If the former, then you probably have a bad backlight inverter, otherwise, a bad LCD, graphics driver.
