We just purchased a 2007 Voyage 35a. It came with a Memorex DVD home theater box that is not turning on. There is power to the outlet. Am I missing something simple or could the box just have gone bad. The previous owners didn't say anything about it not working other than they didn't like the surround sound when watching TV so they unlplugged it from the TV. We haven't tackled taking the TV out and looking behind it, but I wouldn't think that should make a difference on the home theater box not working. Any suggestions?
