TCL 43P718 : Apple TV and HDMI CEC won't turn the TV off

Hi all,

I've got a new TCL 43P718 to go along my Apple TV 4. I've enabled all HDMI CEC settings on both the TV and the Apple TV.

But I've got a problem : when I use the Apple TV remote, I can't turn the TV off automatically. I can turn it on, but not off.

Whereas, when I use the TV remote, I can turn the Apple TV on and off automatically.

So why can't I turn the TV of automatically with the Apple TV remote? I've tried switching HDMI ports, I've tried turning on and off all the HDMI CEC settings, both on the TV and the Apple TV, I've reinitialized the TV settings, I've updated it… still no progress.

Any idea what I'm missing?
