Hello, it's my first post here.
I have a 1.33 Ghz powerbook. Some time ago the colors went inverted and the display lose some sharpness and brightness.
If I do the trick of inverting the color in Universal Access and it never returns to what it should look like. I have never had a kernel panic, and I can work with external monitor.
Any suggestion of what part it is the damaged, and approximately how much would it cost? I checked to see LVDS cable buf seems OK, and I suspect the display itself is working.
