Why denon receiver turns OFF by itself?

Other than a physical problem, the two main reasons a unit’s display would shut off on its own would be if the Dimmer button was pressed and the Dimmer Mode is in the OFF position or if Pure Direct was enabled. You can do this by selecting the Dimmer button on the front panel of your unit.

How do I reset my Denon AVR 3311ci?

Press ON/STANDBY button while simultaneously pressing STANDARD and DSP SIMULATION buttons. 3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and the microprocessor will be initialized.

Why does my Denon AVR keep shutting off?

My Denon AVR 15-13 5.1 receiver has developed the habit of randomly shutting itself off causing the power light to blink red at an interval of twice a second. I disconnected all the speakers and peripherals, even the subwoofer, but it still keeps shutting off.

Why is there no sound coming out of my Denon TV?

An HDMI cable runs between the two units and is connected to the ARC input. The receiver turns itself on…and then a minute or so later, it turns off. No audio is coming out of the speakers because the TV remains off. I swapped out the Denon for another unit….same problem.

Why does my AVR turn on in the middle of the night?

Have exactly the same issue with the AVR-S501BT, turns on in the night a few times a month. In addition I have the pass-through switched off and the receiver set to turn on with mute on yet when it powers on by itself it does so with sound on (from the tivo).

When does my Denon x2500h turn on and off?

Every morning usually around 8am my Denon x2500h will suddenly turn on and then turn off after 30-40 seconds. It doesn’t go to the last audio input it simply goes to tv audio. Last week I thought that perhaps the TV (Sony xf90) was looking for an update around this time of day so I turned off auto update but the problem came back today.
