Guys, I have connected 65F8000 with HDMI ARC to the Denon AVR 2312 (ARC) receiver . And used this connection for audio return from TV to the receiver fine. But today suddenly it stops. No sound to the receiver... If change the speaker settings to the TV speakers - it sounds out of TV, but returning back to receiver - nothing... Restart both of them, but no fix. Any ideas to solve it? And what is the way of TV default reset?

Be sure you use the correct HDMI ports on both TV and your Denon.
ARC is supported on only ONE of the HDMI-ports. Check your manual.
Also be sure that ARC is enabled/activated in the Denons system setup menu.

Sure. As said -it worked perfectly till this morning. And suddenly stopped.... The same connection. The same cables...

I have had a similar problem, disconnecting and reconnecting all devices fixed it. I had to disconnect HDMI and power cables too.

Total power shutdown with the main home.circuit breaker and hdmi cable out helped. Now it is OK

I had same problem. I''m going to check your solution now. I've made hard reset of mu f5300 and still nothing.

For me the working solution is: to power off (disconnect the cable from electrical receptacle) both - tv and audio receiver, disconnect the hdmi cable, wait a minute, connect the hdmi cabke back, connect the electrical cable, powee on both - tv and audio receiver.

THX lads. It works!!! I've been fighting with this all day and nothing. Looks like it was fault of home cinema cause i did not unpluge it from main.
Thanks once again. Any way great forum!! O've discovered it today.
