I purchased a MacBook Pro around a week ago. It's a MB134X/A I have been really happy with this product until last night when all of a sudden I started to get black lines through the bottom of the screen. I shut down waited 30 seconds and turned my shiny new Mac back on. This seemed to resolved the problem until now. Now not even turning the unit off and back on will fix this. When I turn the brightness all the way up it is less noticeable but at low to medium brightness you can really see it. The problem is intermittent. Has anyone else experienced this problem or knows the cause? How did you over come this problem. I don't really want to have to send it to Apple if it's a hardware fault as I believe I could possibly be waiting awhile to get it fixed. Any advice or help would be greatly appreciated. I have attached some screenshots.
