Narrative:
This was an EFIS equipped airplane and all 'glass' displays went blank during the power disruption. This was also the first flight after this aircraft was returned to service by stl maintenance for this same previous write-up. Fortunately; we were in VMC conditions when we lost our instrument displays. Experienced temporary electrical failure after departure from stl. System; returned to normal after leveloff. Returned to stl for normal under maximum weight landing. No emergency was declared.

Title: AN MD80 CREW RPTS EFIS BLANKING FOLLOWING A TRANSIENT ELECTRICAL FAULT. NORMAL SYSTEM RETURNED AT LEVELOFF. CREW RETURNED TO DEP ARPT.
Narrative: THIS WAS AN EFIS EQUIPPED AIRPLANE AND ALL 'GLASS' DISPLAYS WENT BLANK DURING THE POWER DISRUPTION. THIS WAS ALSO THE FIRST FLT AFTER THIS ACFT WAS RETURNED TO SERVICE BY STL MAINT FOR THIS SAME PREVIOUS WRITE-UP. FORTUNATELY; WE WERE IN VMC CONDITIONS WHEN WE LOST OUR INSTRUMENT DISPLAYS. EXPERIENCED TEMPORARY ELECTRICAL FAILURE AFTER DEP FROM STL. SYSTEM; RETURNED TO NORMAL AFTER LEVELOFF. RETURNED TO STL FOR NORMAL UNDER MAX WT LNDG. NO EMER WAS DECLARED.
