PowerBook G4, Aluminum 15 inch, 1.5 GHz.

LCD backlight not working, keyboard backlight not working (just noticed this)

Have replaced the inverter twice and the small antennae board, no luck.

Suspect the logic board has a problem, have seen something about the VDIM circuit not working, thus the backlight not working, maybe.

Is there something common between power for the LCD backlight and keyboard backlight?
