My Powerbook was working fine until yesterday when I picked it up and noticed it was hot to the touch. It seems for a few days it never went to sleep when the lid was closed. Now the video has problems. When booting there is lines running all over like a 1950's tv losing reception. When it is at the desktop it is much better but all the fonts are bold. The boldness seems to be from a double image. Like the image is doubled but only offset a hair to the right. The top left of the screen's text areas are more red than the rest. If you can imagine an old tv and someone messed with the video adjustment pots.
Any ideas? Is the video card burning out or did it get too hot?
