Behringer RD-8 will not power on


Has anyone else had an issue with the Behringer RD-8 turning on? 

It worked fine. I powered off. next day, went to power on... and nothing. I know power is reaching it, the "sig" light blips for split second, but nothing after that. no lights, no led, nothing.

I have only used it twice.First time was to set it up, do the update on firm ware. Second time I just used the trigger button to go through the bass, snare etc. and set the pot knobs. Very disappointed.
