What to do if my Yamaha R-V503 fails to turn on?

If your Yamaha Receiver fails to turn on or suddenly goes into standby mode, ensure the power cord is securely plugged in. Also, check that the IMPEDANCE SELECTOR switch on the rear panel is correctly set to either the upper or lower end. If the issue persists, it might be due to external noise or a misoperation. In that case, put the unit in standby mode, disconnect the AC power cord, wait 30 seconds, then reconnect and try again.
