I just bought a Sony HT-7000DH home theater system. Seemed like a decent middle of the road setup to start with. It sounds good in the room I have it in but when it's quiet I get a clicking sound about every second. It's kind of annoying. Sony support said I should mail it to them to get it fixed but I'd like to troubleshoot it a bit first. Anyone have any ideas? From a couple reviews I have read after the fact, I'm not the only person w/ this problem.
