Thanks for your message. But just so you know, if you want Samsung support, I support US products and customers. And from what I can tell, this model is for Australia. (Correct me if I'm wrong.) So while I can't help you directly, if you want Samsung help, here's the Samsung Australia portal for support on that product: http://www.samsung.com/au/support/model/PS51E550D1MXXY
But we got a nice little community here that includes people from everywhere in the world, and they might have a few other suggestions to help you out.
Hope this helps you!
<span id="INSERTION_MARKER">I have just bought a new Television Model No.PS51E550D1MXXY Series 5+ to go with a just bought Samsung Bluray Home Entertainment System (Model HT-E5550W/XY). I can get audio just for the tv at one time or if i want to use the bluray i have to manually change it to the surround sound speakers and back and forth. Am I able to get use of the surround speakers for just the tv as well as the bluray? And preferably only one button to change from tv to bluray as at the moment i can go to support and change to audio back and forth from tv and bluray? Hope you all understand! Any help is appreciated.
