First, I would check all of your connections going into the amplifier. Then make sure you have your amplifier set to Bluetooth. Also check your volume level and make sure you don't have the sound set to mute. If you still get no sound from the amplifier, contact the manufacturer (Yamaha).
Sorry, there was a problem. Please try again later.Did you check to make sure none of the wires became detached? Also check your that your source channel is correct.(AV1 etc..) How old is the unit? The first unit I had lasted 10 years and I just replaced it with this one. Also make sure you didn’t accidentally hit mute as the mute button is located just below the volume down button and I hit it often. Hope this helps.
