What to do if my Yamaha R-S500 Receiver fails to turn on?

If your Yamaha Receiver fails to turn on, ensure the power cable is firmly connected. Check that the impedance setting matches your speakers. Also, verify that the speaker wires aren't touching each other, as this could activate the protection circuitry. Confirm that the IMPEDANCE SELECTOR switch on the rear panel is correctly set. If the unit experienced a strong electric shock, put it in standby, disconnect the power, wait 30 seconds, and then reconnect it.
