## Discrepancy

IN BOUND STARTED THE APU AT 2500' AT 200 KTS  AND AS THE APU WAS POEWERING UP THE #1 MCDU WENT BLANK AND WE HAD AN ELECTRICAL SMELL IN THE COCKPIT.  SHUT THE APU DOWN AND THE #1 MCDU CAME BACK 'ON'AND LANDED NORMAL.  REPLACED CONDENSER BAG AND PERFORMED OPS CHECKS OF THE APU AND TESTED GENERATION SYSTEM. CHECKS ARE GOOD WITH NO LEAKS OR ABNORMAL SMELLS NOTED.
