What exactly do you mean by "background music on TV shuts off my Samsung"? Are you saying that your receiver powers off?
Great to hear about Samsung service. My neighbor sold his house and moved onto his boat. In the downsizing process I ended up with his Samsung setup. However, no manuals and, although I haven't put much effort into it yet, I can't get it to work with my TV. Can you give me the contact info for their service dept? It'd be much appreciated.
Thanks!
