Make sure to select all cec options on tv

Hi, Tim. My name is Ron, I'm an independent advisor. I will be more than happy to help you.

Make sure to check first if your TV support the HDMI-CEC feature which sends commands to and from CEC-enabled devices (such as TVs and AVRs) that are connected to the console.

To turn off the TV along with the console, please do the steps below using your console.

Press the Xbox button  to open the guide, then go to Profile & System> Settings > General > TV & display options > TV & A/V power options.

You will need to turn on the HDMI-CEC function there, please also make sure that HDMI-CEC is also enabled on your TV settings.

After setting all of that up, on the TV & AV power options screen check the HDMI-CEC box to activate CEC then turn on the following setting "Console Turns off other devices."

To turn on your TV automatically when you turn on your Xbox using the CEC option, you can follow these steps

Press the Xbox button on your controller to turn on your console.

Go to Profile and system.

Select Settings.

Go to Generals.

Select TV and display options.

Select Device Control.

Enable HDMI-CEC

If you've already enabled CEC in your TV settings and you're still having issues, it could be that your TV doesn't fully support Xbox's HDMI-CEC feature.

In that case, I would recommend that you contact Xbox support for additional assistance, remember that I am a gamer just like you with a little more experience in the field of Software and Hardware.

Hello Rodrigo, I have tried both energy saving and the suspend options.

Apparently this happens when you turn the system remotely by pressing the Guide button on the controller. Sometimes (not all) when you turn the system by pressing the power button on the console itself, CEC kicks in and the TV turns on. Also, resetting CEC in the settings (disabling, restarting, enabling cec and restarting) makes the Series X turn the TV, which makes me think it's not related to the TV CEC configuration, or a hardware or cable failure, since it only fails when turning the system from the controller I think it can be assumed that the problem is on the software side.

I will check the reddit, though I don't use reddit myself, for more help, thanks for the resource. I will be waiting for more responses and hopefully by me making noise here someone at microsoft notices there's a bug with CEC in their high end videogame console.

Cheers

Hello, please check if your console has HDMI-CEC enabled. If yes, turn off all the features temporarily.

You can check this doing the next in your console. Open Settings > General > TV & display options > TV & A/V power options.

You can find more about this here:

After that, disable HDMI-CEC features in your TV as well. You should be able to find that via TV settings.
