TV auto on
I have seen this happen on Sony, LG, and Samsung TV's. The fix for this on all the TV's was to disable the wake function on the HDMI inputs under settings power management. The HDMI-CEC will allow your devices connected be controlled by your TV remote, but this also allows connected devices to turn on your TV, I had a external speaker that would randomly wake up my Sony TV, a firestick that would wake up my LG, and the cable box for the Samsung. I turned off all the CEC related power management, which is problematic on all TV's, and have not had any issues after doing so. I was beginning to think I had some ghosts that liked watching TV. Lol
