Bose 3-2-1 GS

During recent electrical work on my home, the power was shut off to the wall outlet into which my Bose 321 GS was connected. When the power was turned on, the Bose screen displayed "Bose 1 2 3", but the unit does not respond to any of the set-top controls, incuding on/off or to the remote.

Unplugging the power to the acoustimass unit and the acoustimass unit from box and then reconnecting has no effect.

Any suggestions anyone has would be appreciated.

Thanks

Thanks John. That may be my best if not only alternative.
