[geeks] Problem with my Screen

[vance at neurotica.com]

The screen on my PowerBook G4 (Gigabit Ethernet) seems to have developed
two vertical lines about two thirds of the way to the right side of the
screen.  One is green and one is blue and they are about an inch and a
half apart.  What causes this?  My laptop has been sitting on a table for
a while and hasn't been stepped on or dropped or anything like that.  Any
ideas?  I'm thinking of taking it to the Apple Store to have them look at
it.

Peace...  Sridhar
