These have been working fine for almost a year. Recently, the receiver stopped being seen by the tv as an anynet device. Whereas previously the tv sound would arrive through the receiver via the arc hdmi port, and could be controlled by the tv remote, that has also stopped working. The receiver does switch off when the tv is powered off still.
At the same time, the 3d function on the tv stopped working .. No longer pairs with any glasses..
And the marantz stopped being visible to apple devices through AirPlay.
Now I don't see how any of these can be connected except that they all happened at the same time.
I called samsung support and their only suggestion was to reboot the tv to factory.. Which I did. I also changed the hdmi cable.
Any suggestions for any of these issues gratefully received . Bruce
