Powerbook g4 question
I have a 12 inch powerbook g4 Aluminum and the screen is dim,and discolored in some areas but it is really bright at the bottom like it supposed to be brighter.is it the backlight and inverter or is it just the lcd? it works flawlessly other than that. Any help would be appreciated.

I would think it's the inverter or panel... if the backlight goes, it's usually all or nothing. They are simply CCFL bulbs... like the long tube florescent lights in stores or garages... just a lot smaller. If they burn out, the screen will be all dark, with the faint outline of images on the screen.
Hopefully it's the inverter, as that is the cheapest fix!
