Hello, 

                I have a B&O Stereo, model: BeoCentre9000,  and the left tower speaker is offline. It displays an orange indicator, where the right speaker performs beautifully, and has a green indicator.

I have plugged the right speaker into the left output and that works. Unplugging from 120v, and then plugging back in allows the speaker to work momentarily.

I look forward to your thoughts.

Cheers,

Stephen Stutz
