## Discrepancy

DURING FLIGHT, THE CREW REPORTED THEY LOST NR 1, 2, AND 3 DISPLAY UNITS ALONG WITH THE FLIGHT DIRECTOR AND NON-ESSENTIAL BUSS 1 FAIL.  THE CREW PERFORMED AN AIR-TURN-BACK.  MAINTENANCE REPLACED THE 1VE PANEL AND WITH OPERATIONAL CHECKS GOOD THE AC WAS RETURNED TO SERVICE.  NOTE: THIS 1VE PANEL WAS JUST REPLACED THAT DAY TO ELIMINATE AN APUAND DC POWER PROBLEM.  (K)
