Old story: troubleshooting a friend's PC over 10 years ago. Computer randomly didn't boot. Figured out if we actually screwed his 3dfx Voodoo2 to the case, it wouldn't boot. Would work fine without the slot screw. Go figure.

I knew it was either power related or shielding/interference/device (all inputs) related. I had tried a few devices before asking, I had re-seated everything, etc. all before asking here. I had ruled out device issues (I tried our desktop, laptop and an iPod). I then thought it could be the 21" CRT it sits next to. But then I remembered that these are PC speakers, it shouldn't matter. So then I tackled shielding tonight, thinking the cable from the pod to the sub might be damaged, here I found the solution. It's not the cable that gets damaged, it's the connectors.
The fix is to unscrew the VGA style screws from the control pod. For some reason, you get interference with them normally tightened. How weird is that!

It is a 60hz hum (we all know exactly what that sounds like) that is the exact same no matter if the control pod is on or off. Any time it is plugged in and the circuit breaker is closed it hums. I'm tempted to take it apart and inspect for damage, but I don't think I could see anything.
I'm going to figure out if it is a ground loop. This seems likely.
SpotTheCat wrote:Well. I think it is the control box. Strange symbols pan across the display when the coaxial input is selected, followed by the power button flashing red and then the unit turns off. Weird, huh?
Being long out-of-warranty, Logitech offered half off a new system (still $200!) but that's approaching what I paid for them in the first place!
Don't get me wrong, I like them, but I think the money would better go to a receiver/home theater setup.

you may have to unplug stuff inside your case or try some shielding
look for cables that go between ur sound card and gpu like USB and firewire
you may have to mess with some case grounds too
potatochobit wrote:sorry I didnt see you had a 'new' hum going on
I have heard quite a few people with broken control things
and you would have to replace the whole unit since they dont sell the control thing sepearte
or check on ebay I think they said control units pop up
is that sub proprietary? if not just get a yamaha or onkyo they got a sale going on I think

Sounds like a ground loop.
