## Discrepancy

FLIGHT ATTENDANT'S REPORTED SMOKE IN THE FORWARD GALLEY AREA WHILE EN ROUTE FROM EWR TO MEX.  THE AIRCRAFT WAS RETURNED TO EWR WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE IDENTIFIED THE SOURCE OF SMOKE TO BE FROM THE VIDEO SYSTEM CONTROL UNIT (SCU) BASED ON THE BURN SMELL NOTED INSIDE THE UNIT.  THE SCU WAS REMOVED AND REPLACED.  SCU BITE TEST CHECKED GOOD.  NO OTHER FAULTS WERE FOUND.  TEARDOWN REVEALED THAT THE HEAT DAMAGE AND RESULTANT SMOKE WAS DUE TO FAILURE OF A CAPACITOR IN THE SCU.
