James,
Completely power down the Disklavier by holding in the oblong green on/off button. After it quits blinking, unplug it from the wall and let it sit about an hour.
Plug it back, in and power it up. I think you will find the keys and pedals will start playing again for you.
You MUST unplug the piano from power for this to work.

I connected a set of ear phones and I can hear the music. Nothing from the keys.
