## Discrepancy

DURING A ROUTINE SCHEDULED INSPECTION, PASSENGER CABIN ENTERTAINMENT SYSTEM CONTROLLER P/N 1451-1-1 AND 1-1-2 COMPONENTS WERE BEING REPLACED DUE TO CUSTOMER REQUEST, PRIOR TO INSTALLATION A BENCH CHECK WAS PERFORMED ON UNITS AND THE UNITS FAILED TEST. UPON OPENING THE COVER OF THE UNITS FOR INSPECTION, CORROSION WAS NOTED ON THE INSIDE OF THE UNIT DUE TO THE INTERNAL 12 VOLT GELPACK BATTERY LEAKING, CORRODING INTERNAL IC COMPONENTS.  UNITS INSTALLED IN THE AIRCRAFT EXHIBITED SIGNS OF CORROSION ALSO. UNITS CAN BE INSTALLED AT VARIOUS LOCATIONS WITHIN THE PASSENGER CABIN AND MAY BE INSTALLED ON VARIOUS OTHER MODEL AIRCRAFT.
