Logitech X-530 power sub not working

[slow2anger]

I have two sets of Logitech X-530's speakers. One set will not play or power on but when i switch the speakers to the other power sub they work fine. What could be wrong with the power sub?

The sub-woffer usually contains the power amp, so that's why one set works and the other set doesn't. It could be a blown fuse if you can get to it

I agree with Tmagic, the subwoofer on the Logitech X-530's is where the amplifier is located. Like Tmagic said, if you can open the subwoofer, check the fuse. otherwise it may have a bad amp.
