Thanks for your message. But just so you know, I support US products and customers. And from what I can tell, this model is for Australia. (Correct me if I'm wrong.) So if you want the most accurate information, here's the Samsung Australia portal for support on that product: http://www.samsung.com/au/support/model/PS50C91HDX/XSA
Hope this helps you!
My TV just went out while I was watching. Anyone have a similar experience? Both picture and sound just went off while I was watching. Turned it off and back on again but no joy. The screen is just black, no pixels are powered on. Would appreciate anyone's advice. Did you try and have it repaired and if so, what was wrong with it? I'm guessing a board but who knows which one. Appreciate any help.
