No sound output from Bose 3-2-1 Base AccustiMass Module.

My 3-2-1 Bose AccustiMass Base Module no longer emits any sound. The LH and RH speakers operate properly. Input selections AUX, CD/DVD, VIDEO 1 and VIDEO 2 are also OK?

How can I troubleshoot and repair. Also, a schematic and parts list of the module circuit board would help.

Have you tried the following two reset options:

Turn the media center off for 10 seconds, then on again, to restore communication between the media center and the speakers.

Unplug the Acoustimass module power cord from the outlet for a minute, then reconnect it. This allows the unit to reset itself.

Jayeff, thanks for your quick reply. I already tried the (2) options suggested prior to submitting my inquiry. There was no change or improvement. The base AcoustiMass module still doesn't provide any output whatsoever. Any other suggestions.
