## Discrepancy

SHORTLY AFTER TAKEOFF CREW NOTICED AN INCREASING TREND OF A BURNING ELECTRICAL SMELL.  AFTER APROXIMATELY 15 MINUTES THE NR 2 PRIMARY FLIGHT DISPLAY FAILED WITH A "DISPLAY TEMP" FLAG.  THE APPROPRIATE CIRCUIT BREAKER WAS PULLED, AND AIRCRAFT RETURNED TO KAPA WITHOUT FURTHER INCIDENT.  MAINTENANCE VERIFIED THE FAULT AND FOUND LOW AIR FLOW TO THE NR 2 PRIMARY FLIGHT DISPLAY.  AFTER REMOVING AN INK PEN FROM THE COOLING FAN AIRFLOW WAS BACK TO A NORMAL STRONG FLOW.  THE NR 2 PRIMARY FLIGHT DISPLAY WAS REINSTALLED, AND OPERATIONALLY CHECKED GOOD.  AIRCRAFT WAS RETURNED TO SERVICE.
