Problems with Mac => Color Laptop only using gray scale

Posted on 2006-04-17

The laptop is a Mac PowerBook G4 with 1GHz cpu and 256MB of RAM.  It is running OS X 10.3.9.

The problem is that everything is in a gray scale.  WHen the computer is booting up the screen is colorful (has all the right colors and looks great).  When I log in the desktop is gray scale and appears to not have color.  When I change the resolution the screen goes blue for a second and then goes back to gray scale.

This laptop is my grandma's so I have no clue when the problem started.  She works at a university and says that the IT Department there has been unable to fix it.

I am a Windows person so I do not know a whole lot about Macs and I do not know what else I should tell you.  Please feel free to ask questions.
