## Discrepancy

AIRCRAFT WAS GROUNDED: DURING CRUISE FLIGHT STANDBY ALTITUDE INDICATOR ISIS WENT BLANK AND DISPLAYED OUT OF ORDER MESSAGE AND CODE 8200 0000 0000. AIRCRAFT DIVERTED TO DENVER WHERE IT LANDED SAFELY WITHOUT FURTHER INCIDENT. NO EMERGENCY WAS DECLARED.  MAINTENANCE REPLACED THE INTEGRATED STANDBY INDICATOR AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK PER AMM 34-22-25.
