Why does my Denon Stereo Receiver turn off suddenly and the power indicator flashes red?

If your Denon Stereo Receiver's power suddenly turns off and the power indicator flashes red, it could be due to the protection circuit being activated. This might happen because the internal temperature has risen too high. To solve this, turn off the receiver, let it cool down completely, and then turn it back on. Another cause could be that the speaker wires are touching each other or the receiver's rear panel. In this case, unplug the power cord, twist the speaker wires tightly or terminate them properly, and then reconnect them. Also, ensure you are using speakers with the correct impedance as specified for the receiver.
