A little over a month ago I got rid of Xfinity cable tv. The Samsung Q80R is also connected to my gaming PC. So when I'm not streaming through an app, the screen is the home screen of the PC and the PC is always on. As I'm shutting off the tv I always back completely out of Youtube TV, Max, or whatever I'm watching and it goes back to the PC home screen then I turn the tv off. But right after I got rid of cable, the tv will turn itself back on. It's usually within 5 minutes after I turned it off. But at night I've turned the Q80R off in the living room, got into bed, then I see the light come back on in the living room and the tv has turned itself back on. I can't figure out what is causing the tv to turn back on. It doesn't do it every time but it's been several times in the last 6 weeks or so after I got rid of cable.
Hello! Thank you for reaching out! As what @ChaosSaber said please try the TV without it plugged into the pc. Also make sure that anynet+ is turned off as this can cause this issue to occur as your pc is always on. You can turn it off by the following: Settings > General > External Device Manager > Anynet+ (HDMI-CEC) and turn it off
Also depending what's on your pc there could be some background process cause the TV to receive a signal and turn on by anynet+. Also depending on what's on your pc make sure there is no background apps that can turn a connected display on or any software that can do this.
