## Discrepancy

IMMEDIATELY FOLLOWING REFUELING, THE PILOT TURNED ON THE ACFT BATTERY & THE PILOT'S MAIN DISPLAY UNIT DID NOT COME ON.  SHUTDOWN POWER & INITIATED THE SEQUENCE AGAIN AFTER WAITING 1 MINUTE WITH THE SAME RESULT.  HE THEN SHUT DOWN POWER & CALL MX.  MX ARRIVED TO TROUBLESHOOT THE PROBLEM.  DETERMINED TO BE A BAD DISPLAY UNIT.  THE SYS WAS DEFERRED, CAT A - ONE TIME FLIGHT TO MX.  THIS ACFT CURRENTLY REMAINS OOS AT THE TIME OF THIS SUBMISSION AWAITING A SERVICEABLE DISPLAY UNIT.
