Question

I replaced the fuse and have tried other power outlets. It is correctly set to 110V.

I would like to send it to a local repair shop to be fixed however they need a wiring schematic if its available.

I would also be happy to pay to send it in to Sonus to get repaired however this subwoofer is already registered through the prior owner so I an unable to register it since it was bought private party. Thank you.

Answer 2

Did You ever get an answer, or found the defect?
..because I now also have the same issue.
Fuse is OK, slight sound when powering up from the internal transformer, but that's it.
No more control LED light up.
