## Discrepancy

AFTER TAKEOFF, PILOT NOTICED THAT THE TOP VEMD SCREEN HAD REVERTED BACK FROM THE STANDARD FLI IN FLIGHT SCREEN TO THE 3 PARAMETERS SCREEN & HAD A FLI FAILURE IN YELLOW ON THE INFO BLOCK.  NO OTHER CAUTIONS & WARNINGS WERE NOTED OR PRESENT.  PILOT ABORTED FLIGHT & RETURNED WITH NO OTHER PROBLEMS, ISSUES OR CAUTION & WARNINGS.  LANDED SAFELY & ONLY WHEN TAKING THE ACFT FROM THE FLIGHT GATE SETTING BACK TO THE IDLE SETTING DID THE PILOT RECEIVE A FLASHING AMBER GOV LIGHT ON THE MASTER CAUTION WARNING PANEL.  UPON INITIALIZING POWER TO THE ACFT AGAIN THE CAUTION & WARNING WAS NOT PRESENT.  TROUBLE SHOT THE PROBLEM TO A DEFECTIVE T4.5 CONFIRMATION BOX.  REPLACED & OPERATIONAL CHECKED GOOD.
