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.
