Question about Denon AVR-1804 Receiver
Everytime I power on the unit the standby led comes on; the unit then powers down after 5 seconds.
Protection circuit activating. Possibly a shorted amplifier channel or power supply fault. Take it to a Denon repairer

This is battery
related. On top of your unit is a battery pack with three colored led
lights. You can tell what is going on by looking at these. This
information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing green LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.
