## Discrepancy

JFK - AFTER T/O FROM LAX, SMELL FROM FLT OFFICERS SIDE, UNDER GLARESHIED, BY LIGHTS.  SMELLS LIKE OVERHEATING BALLAST RESISTOR.  INSPECTED COCKPIT AREA, DID NOT LOCATE ANY DAMAGE.  SUBMITTER STATES, SUSPECT OVERHEATING BALLAST RESISTOR.  DEACTIVATED FLIGHT OFFICERS SIDE FLOOD LIGHT ASSY, UNABLE TO DUPLICATE SMELL WHEN POWER WAS APPLIED.  DEFERRED PER MEL 33-1.  REPLACED BALLAST AND FLOOD LIGHT ASSY.  OPERATIONAL CHECKS WERE GOOD.  REFERENCE EIAA970088.
