So I have a somewhat new Stanmore III that won’t turn on and off. I was gone for three weeks and when I came back something had happened to it. I checked the power outlet, that is functional. The cord also looks unharmed. Not sure what to do beyond asking the online shop I bought it from (a reputable one). Anything else I should check or do beyond contacting them? I’d be grateful for tips.
