I'm having a problem with my R front speaker. I get no sound from it. However, if i hook the L front speaker up to the R cable i do get sound. Vice versa, if i hook the R speaker to the L cable I don't get sound. As such, I figured I had a speaker problem and send it to service center recommended by onkyo. They cannot find anything wrong with the speaker. They're currently sending if back. I'm anxious to try hooking things up again to see if it works now. But if it doesn't what do i need to do? Any ideas would be appreciated. Thanks.
