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/UA46D6400UMXXY
Hope this helps you!
I cant turn on or off the TV using the remote or the power button on the tv. I have to unplug it from electricity.
I cant access the menu or source either
Is there a way to reset ?
