On start up I get the tone then immediate shut off
I push the power button, get the start chime and the power is immediately turned off. Pushing the power button again will do nothing.
If I unplug the device and plug it back in I can again get the start up chime but same result with immediate shut off. I have had the machine for a few years and it has worked well until this occurred, which may have been triggered by a power outage.
