What to do if my Yamaha HTR-5660 sound suddenly goes off?

If the sound from your Yamaha Receiver suddenly cuts off, it could be due to the protection circuit being activated. Check that the IMPEDANCE SELECTOR switch is set to the appropriate position and then turn the unit back on. Also, the sleep timer may have turned the unit off, so turn the power back on and play the source again. The sound could also be muted, so press MUTE or any operation buttons to cancel the mute.
