I have a Sony DAV C700 system... when watching the TV with the sound going through the speakers, the sound jumps from the left to the right speaker and is never consistently coming from both. The sound has also cut out entirely at times. Reaching behind the system and jiggling some wires temporarily corrects it. I've disconnected and reconnected everything numerous times to no avail. I've also purchased new Monster cables which made no difference.
We don't experience this problem when playing DVDs.
Any ideas? I believe I've got everything hooked up properly per the user manual, but I'm far from a pro at this!
