Talked to the rep and he wanted me to confirm the connections on the sub. Here are the pix:

Anyone spot anything out of the ordinary?

I am curious why anybody would ask you to take the covers off. Are you sure the rep wasn't asking about the connections on the outside?

Well the rep seemed very confident that the issue was a simple connection thing; one of the connectors was probably not seated right and this was what was causing the audio signal to be detected but no sound would be output.

So instead of shipping the whole thing, it was thought that we could simply take the cover off and see if there are any loose connections around. Unfortunately I found nothing loose and everything seemed to be seated firmly in place.

I have to agree with Garcianc here: the rep was almost definitely asking about the connectors on the outside of the subwoofer. I can't imagine any manufacturer telling you to open up a product that contains an amplifier as there are dangerous voltage levels inside.

Take a picture of your outside connections, the ones coming from the Yamaha. Better yet, unplug and replug those and see what happens.
