The screen on my PowerBook has been going completely white. At first if I shut down and turned it back on it would fix it for a while. I decided to unplug everything except the power cord and reinstalled OS 10.4.6. After that I reinstalled the 10.4.11 combo update. That seemed to help for a while. Now however, it has gone white and will not even work even if I unplug everything and try to start up on the installation disk. It seems to be functioning just not displaying anything. Any ideas?
