I had to factory reset my Apple TV because some Apple TV apps weren’t working. Once it reset and I set it up including turning on the tv remote settings everything worked except it won’t control my tv power anymore.
Apple TV 4K, tvOS 14
Verify your settings for Settings﹥Remotes and Devices﹥Control TVs and Receivers﹥On|Off
Control your TV or receiver with your Siri Remote or Apple TV Remote - Apple Support
Also verify the HDMI-CEC setting on your TV, so it will accept such power-on/standby signals.
It does control my tv volume but I can’t find out why it won’t turn the tv on and off like it used to
Apple remote won’t turn on TV
