I just helped a friend set up a macbook pro she bought on ebay. It has one of the screens that is yellow at the bottom and white at the top. Looks pretty awful. My question is how things have worked out for those who had this problem? Did Apple replace without any questions, and did you get a display that was good after that? In other words, is it worthwhile to suggest that she tries to get Apple to replace the display or is it just going to be more of the same?
