Topic: Chumby 8 seems to be 'dead'

During the outage last Friday (2/23/2018) my Chumby got 'stuck' looping the last few seconds of a song that played on the radio.
I had to cut power to stop it. Since then my Chumby seems to be 'dead'.
Replugging power did not help. Dark screen, really nothing happens.
I tried another power supply, same result.

If anyone would know some solutions to get it going again ... would be great.
