Unfortunately, you have run into what we ran into.  This is a known issue with older NXT bricks.  I work with two programs that have a total of four robots. This year when we unpacked them, two of them had a screen problem.
 
If you bought them through LEGO Education, call LEGO Education Technical Support at 866-349-5346 and they may offer to replace it for free (although you have to mail in the old one and the turnaround can be 1-2 weeks).
 
If you have a retail version NXT, call LEGO Mindstorms Technical Support at 877-680-2800.
 
Sorry for the bad news.
