My Roku TV volume turns all the way up by itself for no apparent reason. I’ve restarted the TV every way possible. I STRONGLY suggest you not buy / spend your money with Roku TCL tv they are **bleep** and not even worth the headache. I've had this TV all but 4 months for it to malfunction like this.
