I'm not sure that you can.
If you need another remote, one is available on www.samsungparts.com or by calling 800-627-4368. But I'm not aware of being able to toggle that option without the remote.
HI I have a Samsung HT-WS1R soundbar attached to my Samsung LED tv. The bar is normally off when I watch tv - I turn it on to watch movies. Somehow I changed something, so now the soundbar comes on when the tv is on. The manual says to disable the auto power link function via the remote. However, I dont have a remote for this as it was a floor model and the dealer lost it. How can I disable the auto power link function without the remote?
