## Discrepancy

WHILE CLIMBING OUT OF LGA RECEIVED A BLD 2 FAIL MESSAGE.  RAN CHECKLIST AND BLEED CAME BACK ONLINE.  A FEW MINUTES LATER RECEIVED MESSAGE AGAIN AND WERE NOT ABLE TO GET IT BACK ONLINE.  AT FL250 RECEIVED A BLD 1 FAIL MESSAGE.  DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 2 NAPRSOV, AND COULD NOT DUPLICATE THE FAULT ON BLEED 1.  OPS CHECK GOOD.
