Questions and answers
Why won't my rx-683 receiver turn on when I press the power on button?? The only thing that happens is the red light just blinks
The Yamaha RX-V683 receiver may not turn on and only blink a red light because the internal microcomputer has frozen due to an external electric shock (like lightning or static electricity) or a drop in power supply voltage. To fix this, hold down the MAIN ZONE key on the front panel for more than 10 seconds to reboot the unit. If the problem continues, unplug the power cable from the AC outlet and plug it back in.
