## Discrepancy

CRUISE FLIGHT AT FL 260. NOTE: FOUR SCREENS IN AIRCRAFT, TWO PFDS, AND TWO MFDS. PFD #1 STARTED SHOWING SHADOWS OF THE HSI AT THE TOP AND BOTTOM OF THE SCREEN WITH WHAT LOOKED LIKE STATIC LINES ACROSS THE SCREEN. MFD #1 WENT BLANK. THEN, ALL 4 SCREENS WENT BLANK FOR A FEW SECONDS, THEN CAME BACK ON, WENT OUT AGAIN THEN BACK ON, BUT WITH MFD #1 XED OUT. CAS (CREW ALERTING SYSTEM) MESSAGE INDICATED AGM #1 FAULT, WITH A CHECK DU2. SV (SYNTHETIC VISION) WENT OUT ON BOTH PFDS. MFD #1 REMAINED XED OUT. SWITCHED PFD #1 TO AGM #2 AND WAS ABLE TO GET THE PFD BACK, BUT WITHOUT SV. APPROXIMATELY 5 MINUTES LATER, THE SV CAME BACK ON. CONTINUED FLIGHT TO DESTINATION. REPLACED FAILED HONEYWELL AGM #1 MAU CARD P/N 7036410-1904 WITH TESTED HONEYWELL AGM MAU CARD.
