If the sound on your Yamaha Receiver suddenly goes off, here's what you can check: * The protection circuitry may have been activated due to a short circuit. Ensure the IMPEDANCE SELECTOR switch is in the correct position. * Make sure the speaker wires are not touching each other and then turn the power of this unit back on. * The unit may have become too hot; ensure the openings on the top panel are not blocked. * The automatic power down function might have turned the unit off. Change the automatic power down setting (“APD TIMER” in the Advanced Setup menu) to a longer setting, or disable the automatic power down function by setting the POWER MANAGEMENT switch on the rear panel to OFF.
