I have seen this problem many times and the cause is usually a bad connection between the screen, and the motherboard. If you pry the plastic band around the screen off carefully (I recommend starting from the bottom middle where you can see the SAMSUNG logo), you can see the connections on the bottom left hand side of the screen. You can inspect for any obvious problems. When you are done the plactic that goes around the screen will snap back into place when you apply pressure all around it.
