Didn't see your answer before, Chris. Unplugging doesn't help, the mains cable was actually the one cable I changed on the 5000C smile I have tried unplugging again, but no go.

Is there a way, with the speaker in its current state, to read any settings it has? It would help me setup it afterwards...
