Everytime I turn my xbox one on it turns on and off my tv. I have my other Xbox one out in my living room connected to a vizio, yet when ever I power on the xbox connected to the vizio it turns on my samsung tv in the bedroom. Ive tried turning stuff off in the tv setting but its not working. I have no idea why its controlling the tv if its hooked to a totally different one.
Out of curiosity, did you connect your XBox one controller to the television by any chance? If so, go to the televisions Bluetooth settings and remove the controller from the device settings.
