I just booted my PowerBook G4 and noticed that the white balance and colors of the screen have shifted. I assumed I could go into display preferences and adjust the colorsync profiles. However, when I try to click on a profile and calibrate, I receive the error: Can not calibrate display, The factory profile for the display could not be found. What should I do? I have tried repairing the profiles from the ColorSync Utility, it says that no repairs are needed. Also tried, repairing permissions using Disk Utility. The last thing I want to do is an archive and restore. Any other suggestions?
