## Discrepancy

AFTER TAKEOFF, PUT GEAR HANDLE UP AND GEAR SEEMED TO RETRACT NORMALLY BUT LEFT GREEN A LIGHT STAYED ON.  CYCLED GEAR HANDLE AND WITH HANDLE DOWN GOT 3 RED B LIGHTS WITH NOSE AND RIGHT MAIN RED A LIGHTS ON CONTINUOUSLY, GEAR WOULD NOT EXTEND AND HYDRAULICS WERE NORMAL.  USED ELECTRONIC OVER RIDE PROCEDURE AND RETURNED TO LAX.  REPLACED LEFT GEAR A SYSTEM WIRING HARNESS AND BOTH PROX SENSORS.  SWUNG GEAR AND OPS CHECKS GOOD.
