Help with humming noise from Logitech Z560 THX

Hi all,

I had these speakers for only a short time. It was working great till today. I had to swap out a desk, and reconnect my PC and speaker system back to what I had before. However, now I'm hearing a constant humming noise coming from the subwofer. The humming persist even if I turn off my computer and the power on the Logitech control center. The only way to get rid of the humming is by unplug the main power of the subwofer.

Anyone had this happened before? How do I fix this problem? Thanks.
 
thats a strange problem, few months ago I had this light thumping sound comming from the subwoofer and only way to get rid of it was to turn the power off to the sub. After a few weeks the thumping went away. Maybe you should try reconnecting all the wires and cables and see if that does anything.
