Sleeping Apple TV 4K turns my Samsung TV on.

After I received and set up my new Apple TV 4K, I shortly noticed that my Samsung TV would not stay off. After trying several things, I realized the Apple TV was involved.

I tried different HDMI cables.

I tried different HDMI ports on the TV.

When the Apple TV is not connected to the TV or the Apple TV is not plugged in, the issue goes away. The TV stays off.

I turned the HDMI-CEC functionality off on the TV and that too resolves the issue. However, HDMI-CEC needs to be enabled for my soundbar to work over HDMI-ARC.

In short, my sleeping Apple TV 4K is turning my Samsung TV on shortly after I turn the TV off, every time. I brought my Apple TV to Apple. They tested on other brands but this issue didn’t present itself.

Others on other threads are experiencing this as well. Samsung needs to push an update to handle the Apple TV correctly over HDMI-CEC.

Can you turn off the HDMI-CEC function on the Apple TV instead of the Samsung TV?

I forgot to mention that.

With CEC turned on, on the Apple TV, when I put the Apple TV to sleep, my TV turns off and then, seconds later, turns on.

I get how bothersome that this may be.  By any chance are there any other set top boxes connected to the television?

Yes.

I have a Verizon FiOS STB connected via another HDMI port.

I also have a Bose Soundbar 700 connected to the HDMI-ARC port.

Are there any settings on the Apple TV itself that may be like the CEC setting on the tv?

There is a "Control TVs and Receivers" option in the Apple TV settings.

When the setting is enabled, putting the Apple TV to sleep, the TV will turn off. Seconds later, the TV turns back on.

When the setting is disabled, putting the Apple TV to sleep, the TV will remain on. I turn off the TV and seconds later the TV will turn on.

If this is the only device that this is occurring with, I recommend reaching out to Apple regarding this.
