One of the hinges of my Powerbook G4 broke a few weeks ago, and the colors on the screen have gotten worse and worse (right now the screen is totally blank and I cannot use it). Is there no way to fix it? I know it was discontinued last year and the model is known for having weak hinges. The clerk at the macstore called it an "antique" and said I would have to get a new one. I had my laptop for only three years and was hoping it would last me through college.
