Music Man Majesty Dead

Hello. I inadvertently used rechargeable batteries (3x AA) on my Music Man Majesty. Preamp appears to be dead, no blinking lights when batteries were replaced with fresh alkaline ones. I tried draining the residual power by pluging in a guitar cable to the guitar leaving the other end unplugged. No luck as of yet. Hoping someone with this issue in the past can help. Thanks in advance!
