So I have this Yamaha RX-V6A receiver, connected over LAN.

I noticed it randomly turns itself on from time to time, and then just turns itself off 10-20 seconds later. I thought that something on the networks sends a WOL-type packet, but then why does it almost immediately turn itself off? Ad then again, what might be sending an wake-up packet to the receiver? Could it be something else altoghter?

Does it happen if you have the receiver unplugged from the LAN? That would be easier to test if it was a cable, but you could remove any antenna or delete the WiFi password.

Mine was doing this because of the consoles and fire sticks powering up and rebooting with software updates.

Are you using any form of HDMI-CEC to communicate between receiver, TV or source?

My Marantz has been doing this randomly lately too.. Very annoying as it switches on and off 2 connected Power amps.
Ive put it down to software updates on one of the many connected devices.

Not about when the aircon unit Powers up?... Use to have to use an expensive powerboard with filtering caps to stop a freezer tripping mine in a previous residence
although that was more and off while on rather than on from off
Now small brownouts that make the lights flick can cause the amp to reset. Doesn't power down, just a resync

Thanks for all the replies!

Regarding the setup:

- I have a Sony Google TV hooked up to the reciever using HDMI-CEC. The TV stays off when the receiver wakes up.

- A couple of gaming consoles plugged into the TV

- A Chromecast plugged into the receiver

When the receiver wakes up it shows TV as the source. That's the usual source anyway, but at least it means it's not the plugged in Chromecast that is waking it up.

I can unplug it from LAN to test it, but because it only happens every four hours or so, it's going to be really hard to test. I can't sit there watching it for four hours just to make sure I don't miss it when it does or doesn't do it again. :(

Doesn't seem related to the aircon. Does it whether the heat pump is on or off.

Initialize the network connection via the front panel, do not reconnect the AVR to the network during testing.

If the fault continues, remove HDMI CEC from the equation.

Almost certain it will be turned on/off due to firmware + network connectivity on attached devices, which then turn the AVR on via a CEC connection.

Thanks for your help everybody. Turned out it was... drumroll... Xbox Series X.

It would kick the TV from deep sleep into standby (LED on, screen off), which in turn would swtich the AVR on over HDMI-CEC. Which is kind of disappointing because there doesn't seem to be a way stop it from happening, but at least I now know what's going on here.

Do you have the XBox in Sleep Mode and not fully powered down (this can be adjusted in your settings on the XBox).

If you set your console to power down completely and not just sleep it will use less power, but will take longer to turn on / won't update games in the background.

Sleep mode. It gets turned on/off quite a bit by the kids, so booting up every time would be inconvenient. Between the two inconveniences - longer boot time vs. random AVR power cycles, I'll go with the AVR on/off. :)

Fair enough - it's about 25-30 seconds to boot up the new generation consoles so I don't mind whatsoever (it's enough time to get a drink and put on my headset) - but each to their own :-)
