Yes had this problem with my daughters iBook. Your lucky that you can get it repaired for free. An like someone else said buy the extended applecare. Ibooks have a bad habit of pinching the video cables. I repaired my daughters myself, an found out why the cables pinch they are routed right around the hinges. Most people are lucky and dont' have this problem but is is rather common on iBooks. I would say by postings it is the top issue with iBooks.
