Denon avr 1909 turns off shortly after I turn it on and the red power light flickers on and off. Help?

Check your speaker wires both at the AVR and speaker for shorts, any small wire strand can trigger the AVR's protection circuit..


Twist the wire titley together and then resinsert into the binding post.

Check to see how frequent the red light is flashing:


2 sec - too hot (ventilation problem)


1/2 sec - this can be a number of issues including driving 4 ohm speakers too hard; speaker wire touching another post; amp failure

Read his post closely..

He mentioned it turns OFF immediately upon turn ON, so the AVR is not yet hot. Therefore, ventilation and driving 4 Ohm loudspeakers would not apply..

As the AVR has not had a chance to heat up..


As mentioned previously..

Shorted speaker wires should be checked both at the AVR back side and @ the loudspeaker. The protection circuitry in 7.1 AVRs is very sensitive to shorts, especially since many brands/models have decreased the robustness of their power supplies and output stages.
