Sonos Beam Tv Control On and Off

We have some steps on this thread that may help solve the trouble you're having setting up or using the Beam with certain CEC commands like "off". For LG TVs you may need to check for LG Simplink > Auto Power Sync to make sure "off" is accepted from CEC.

I finally!! got the tv on/off command to work with beam/alexa. As someone suggested I used the name of the room in the voice command and it worked. My tv is: Samsung 55" Class KU630D 4K UHD TV which I purchased about 2 years ago.
The sonos beam is plugged into the HDMI ARC port.

The exact command I used is: Alexa turn Family Room tv on. Or: Alexa turn Family Room tv off.
Before I was saying: Alexa turn TV on/off and Alexa would reply 'OK but nothing happened...

Now it works...and the heavens opened up!
Thank you Rei! Your solution worked for me. Whatever you named your Sonos Beam as during setup (Family Room, Living Room, etc.), just ask Alexa to turn that on or off. It should work.

My Tv will turn on and off but only when I set the source to the HDMI ARC as input, but won't turn off when SKY Q is selected?
That sounds like the TV selectively ignoring CEC commands from sources that aren't the one selected. Might be best to reach out to your TV manufacturer to confirm and see if this is a known issue.

You need to set up devices... either say ‘Alexa discover my devices’ or go to the Smart Home section of the Alexa app.

You need to make sure the Beam is connected to the ARC HDMI socket

Alexa doesn’t recognise my TV as a device, any suggestions?
I have other sonos speakers which are recognised under “devices” but not the Sonos Beam/the tv connected.
If your TV isn't a smart TV that's Alexa enabled, it shouldn't be discovered. Your Beam should be listed in your Alexa app as a Sonos room and as an Alexa-enabled device. You may need to go through voice settings in the Sonos app if that isn't listed, remove and re-set them up. These steps may help.


Thanks Ryan, I’ll keep trying. Volume commands work fine on any HDMI port, it’s just the “off” command that is ignored unless HDMI ARC source is selected. Samsung support haven’t got a clue :D


Have still not managed to get the TV to turn off if any other source is selected other than the HDMI ARC. samsung ue55mu6220. All other commands work fine. Have tried all recommendations so must be the TV not allowing CEC commands when other HDMI ports are in use.

Anyone had any luck resolving?

The command to turn the TV off should be: "Alexa, turn off the TV" or "Alexa, turn off the [room name] TV".

There are some things I've seen work for some TV's, like renaming your Beam to TV or just another name. Also, there are some TVs that you need to turn on a specific setting within them for enabling other devices to turn them off. In a few cases, it helps to use a cable with your other device that doesn't support CEC. To see if it's another device taking over, you could try unplugging that device from the TV, and see if Off and On work from Beam (make sure you're using a different input on the TV, not the HDMI for Beam).

Also, some TV manufacturers don't have off supported or have limited support for it on some models. It may be best to contact the manufacturer and ask if CEC (Simplink for LG) supports turning the TV off from another device.

Would anybody know why I can turn ON my tv using the Beam with Alexa but can’t turn it back off using the voice commands?

If the problem still persists try using your Sonos Beam as the Source (NOT Xbox, PS, Blueray, etc). Fixed the same issue on my Samsung TV.

@All

First let me say that I don't work for Sonos; nor am I affiliated with any technology licensing agency.

I have a 5-6 year old Sony TV with HDMI_ARC connected to a Beam. The issue I had with on/off is that Alexa would ask "which device do you mean as there are several devices called TV". Guess what...she was right. I had two FireTV's on other TV's. The solution was to change the name to Sony and not just TV. Now the command is "Alexa, turn on Sony" and vise-versa.

My point here is I don't think the issue is with the Beam or Alexa...well sometimes it's Alexa :8. The problem is that HDMI-ARC is a standard protocol but how it's implemented is not. Every TV manufacturer has a different name to say that theirs does more than someone else's. Think Windows 10 after the PC manufacturer adds all their "bloat ware" to the OS. Ring a bell:?

Sonos (like Microsoft) can't account for every tweak that a manufacturer may add to their set and how it implements HDMI_ARC protocol with the Beam. Obviously, my 5-6 year old Sony was an early adapter of the HDMI_ARC protocol before it became so widespread; and before manufacturers (including Sony) had a chance to tweak the code.

Bottom-line it won't be Sonos that fixes the problem it will take a consortium to set guidelines as to how HDMI_ARC can be implemented much in the same way the "Wi-Fi Alliance a non-profit organization promotes Wi-Fi technology and certifies Wi-Fi products for conformity to certain standards of interoperability". Until then it will probably be a hit or miss in terms of how HDMI_ARC is implemented in each scenario with a TV manufacturer. Some good, some not so good.

Cheers!

I've just bought a Beam this week and am experiencing this same issue where you can't turn off the TV using any variant of 'Alexa turn off the TV'. I can however turn on the TV, mute and unmute successfully. My TV is an LG 49UF680V connected via HDMI ARC with SIMPLINK on, Auto Power Sync enabled and no other devices connected which could be interfering with the CEC/SIMPLINK.
Does anyone have any additional pointers to try and resolve the turning off issue?

Similar issue on my side with LG TV, can't wait for further updates.
