A couple of weeks ago, my Macbook's display started "flickering." It seemed like I was getting some electromagnetic interference, so I didn't worry much at first. But, it got progressively worse, and now the screen is unreadable.
I took it in to the local Apple Genius Bar, and they took it in for repair. I should have it back in a week or less.
I'm glad I have a Genius Bar nearby, considering all the problems I've been having with recent Apple products. I've been using computers for almost thirty years, but have never needed repairs or service until I bought the iMac G5 and the Macbook.
UPDATE 2007/07/19: Got the Macbook back, and it's working fine now. According to the service form, the following parts were replaced:
