It's possible that your screen or backlight has failed. If a restart doesn't fix the problem, you should have it checked out at the Genius Bar at an Apple Store or an authorized repair centre. If it is a hardware problem and your warranty hasn't expired, you'll either receive a replacement or have the screen replaced at no cost.Hi!
