Xbox One CEC Powering off with TV

Thendercleetz, HDMI-CEC support doesn't have to be an 'all or nothing' feature. If given the proper configuration settings, Kinect IR blaster and HDMI-CEC could work in tandem quite well. As you say most cable boxes don't support this feature, so they would
be continued to controlled by the Kinect, the rest by HDMI-CEC (with the ability to turn this on/off). As for the Power On/Off, HDMI-CEC is a two-way communication if you turn the Xbox on and the TV and AVR are both already powered on it's checks that and
does nothing. For powering off, we would need to be given an additional option (just as PS4 does). 'Power off console only', and 'Power off all components'.

Hi TexasMaster9351! My name is Ricardo an independent advisor ready to help you with this situation!

HDMI-CEC is supported only on Xbox One X, Xbox Series S, and Xbox Series X. You must also enable HDMI-CEC on your TV.

Xbox Series X|S consoles can use an HDMI feature called Consumer Electronics Control (CEC) to send commands to and from CEC-enabled devices (such as TVs and AVRs) that are connected to the console.

This feature can be turned on and off via the TV & A/V power options settings screen. Press the Xbox button  to open the guide, then go to Profile & system > Settings > General > Sleep mode & startup > TV & A/V power options.

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."

xbox does not support CEC

Be that the case, I dont need the xbox to control the input (which is what cec is for) i want the xbox to turn on and off the tv respectively. That feature no longer exists and i did before. THat is the point of this thread for the powering on and off of
the tv through the xbox. THanks @Tezzarrific

It's probably due to the TV sending a
CEC signal via HDMI.

Check if your TV has a setting to turn these CEC functions off. However, most TV makers don't call it CEC, but something fancy like VIERA Link, Anynet+, Aquos Link.

Turn off those CEC commands, and your Xbox should stay off when you start the EPG.
