I have just moved my speakers around in my room and they were working perfectly before. Now only one speaker is playing and when i swap the inputs the other speaker will work fine but they other one wont. What should I do?

Check the mass terminated cable connecting the controller to the base speaker. This connection becomes flacky generally requiring a good contact cleaner solution being needed to be applied to restore the connections.
Go to radio shack and ask for a plastics safe contact cleaner then after disconnecting the mass terminated cable spray it liberly. Then reinsert while still wet then work in and out a few times. You can do this for all the cables connecting to the pc as well. This should restore your dead channel....hop it works :-)

Hi trevorreynol , I have the same problem with my speakers, were you able to get them to work?If you did, could you share, how you did it.

Since the speakers were recently moved, start by verifying they are wired correctly. Both the small speakers should plug into the subwoofer (large speaker). On the back the outputs should be marked L for left and R for right, plug the small speakers in accordingly. The subwoofer should plug to the (usually)green jack on the computer, the subwoofer should plug into power.
