I will have to look at that next weekend. Some of these issues are small and easy to fix ourselves. I would rather fix some of these since I could probably do a better job. The center channel could be an issue with your radio. Check your connections before you write it up for service. Trust me when I say, fix what you can as you go...the dealer may not do as good as you can.
