We've had our Samsung Curved 4K UHD TV; model (UN65MU8500F) and our Sony AV Receiver; model (STR-DH770) for 8 months now, both were working just excellent, as receiver was connected to our 5.1 ceiling, surround system. We were using it 3 days ago to watch Netflix, I placed it back into the Cox cable mode, and turned off all the electronics with the Power All button on cable remote, like always.
A few hours later, I turned on the All Power on the cable remote and the Sony AV receiver was not powering up this time! Tried again, nope. I grabbed the Sony receiver remote and clicked Power, the receiver came on, but NO SOUND!! And I used the Sony remote to try and turn up the volume...the numbers went up for volume, but no sounds whatsoever!! Nothing had been touched on any of the equipment, and no one touched any of the remotes! This was so weird, bcz it worked hours before. I checked settings, etc on the Sony receiver, on the Samsung TV itself and tried to change the Source, nothing would make the sound come through the receiver to the surround speakers, nothing!! I have tried for 3 days now, to figure it out, to trouble shoot with both the receiver manuals & Samsung TV manuals, on line trouble shooting sites for both brands, rebooting, etc.. Everything still makes the sound only come out of the TV and not through the receiver no HDMI, nothing!. It's as if the cable remote and the TV, does not recognize the Sony AV Receiver, its like nothing is synced up?? I really need help!! I could pay the Geek Squad to come to the house and try and make it work, but that would be major $$$, bcz I tried to chat with one online today and they want me to purchase a $199 support Plan & and if I would, I still would have to pay a $49 Service charge for them to come over!! I don't have that kind of money at Christmas time!! I would truly appreciate any help to resolve this sudden issue. I thank you so much in advance, for your help!! And I apologize for the longggg message explaining the issue... just trying to be concise. Thanks!! JC
