## Discrepancy

APPROX 10 MINS AFTER T/O LEFT GENERATOR TRIPPED OFF LINE AND WOULD NOT RESET.  APU WAS STARTED IAW PROCEDURE.  LOSS OF CAPTS FLT DIRECTOR, NR 1 VOR, AND ALL ENGINE INSTRUMENTS WERE CONTINUALLY FLICKERING AND DISPLAYING ERRONEOUS DATA.  GROUND PROXIMITY C/B WAS DISCOVERED POPPED AND WOULD NOT RESET.  OAP SCREEN WOULD DISPLAY FLICKERING MESSAGES THAT WERE UNREADABLE.  REPLACED TRU AND COOLING FAN.
