Hello, When I took my powerbook out of my bag this morning I found the screen to be completely out of control. The image was being distorted with vertical and horizontal lines that would shift around a bit and even change colors a bit (mostly shades of green but also some blues and purples) I am now home and have the notebook plugged into an external monitor. The external is fine, everything is as it should be however the display on the notebook still has the lines. Obviously it seems as thought the screen is broken however I would like to learn to what extend and if there is anything that can be done short of replacing the screen. In case it is relevant I did not handle the computer rough today, it was not dropped or subjected to extreme temperatures. Also I have a 12 inch g4 powerbook running the latest mac osx and nothing was done to/ installed on my computer prior to this problem. I appreciate any help provided! Justin.
