## Discrepancy

MAIN CABIN DOOR WILL NOT CLOSE.  USING OVERRIDE & LIFT BUTTONS SIMULTANEOUSLY, WILL LIFT INTO POSITION BUT DID NOT LOCK.  USING LIFT BUTTON ALONE, NOTHING.  DOOR PINS ALL RETRACT & EXTEND, WHEN DOOR IS LIFTED INTO CLOSED, HANDLE CAN BE MOVED TO CLOSED - LOCK POSITION TO HOLD DOOR, BUT  DOESN`T LOCK & HANDLE CAN BE LIFTED OUT OF POSITION WITHOUT EXERCISING RED UNLOCK BUTTON.  YELLOW UNLOCKED LIGHT DOESN`T ILLUMINATE.  YELLOW DOOR OPEN CAS MESSAGE ALTERNATES ON & OFF APPROX EVERY 30 SECS WHEN DOOR OPEN.  ATTEMPTED A POWER RESET WITH BATTERIES DISCONNECTED TO DIAGNOSE, BUT IT DIDN`T WORK.  ALSO RAN QRH,  DIDN`T WORK.  REMOVED CED MONITOR PCB WITH NEW PCB IAW AMM24-60-40.  CYCLED DOOR SEVERAL TIMES, NO DEFECTS.
