A:Answer Hi ClarkK,
If you are using the device through HDMI, it could cause the auto-on, as Anynet+ is enabled.
Occasionally connected devices such as game consoles (PS5, Xbox) or cable set-top boxes send a turn-on signal, for example, if they have software updates.
We recommend you try turning Anynet+ off as it may be causing auto power on.
Go to Settings > General > External Device Manager > Anynet+, then disable.
I hope this helps!
