## Discrepancy

AFTER TAKEOFF, THE LOWER LEFT CIRCUIT BREAKER ON THE SCRN OVERHEAT TEST PANEL TRIPPED.  FOLLOWED BY AN ELEC ODOR THAT DISSIPATED AFTER A FEW MINUTES.  DURING THE FLIGHT IT WAS OBSERVED THAT THE RT PANEL OF THE LT A SCREEN DID NOT HEAT UP.  REMOVED TERMINAL BLOCK & VERIFIED ELEC ARCHING AT NR 3 & NR 4 TERMINAL POSTS.  TERMINAL BLOCK APPEARS TO HAVE INTERNAL SHORT.  REPLACED TERMINAL BLOCK WITH NEW.  OPS CHECKED GOOD IAW MM 30-41-00.
