Why does my Denon AVC-A1HD Amplifier power off suddenly and the power indicator flashes red?

Your Denon Amplifier might be shutting down and flashing red due to a few reasons: the internal temperature is too high, speaker wires are shorting, the speaker impedance is incorrect, or the unit is damaged. To resolve this: * Turn off the power, let the unit cool completely, and then turn it back on. * Ensure the amplifier is in a well-ventilated area. * Check speaker wires for any contact or stray strands; fix by twisting the core wires tightly or terminating the speaker cables, then reconnect. * Verify you are using speakers with the correct impedance. * If the issue persists, the unit might be damaged; in that case, turn off the power.
