Volume goes up and down by itself constantly. It is not remote, I have removed batteries and issue persists.I think it might be an issue with the board thats connected to the buttons, speakers, aand another seperate motherboard. When I remove the connection it stops, but I can't hear anything since the speakers are connected by it as well. I have attached a picture of the board in question, but haven't been able to find out if I can get a new one anywhere.
I assume you're referring to a RokuTV. You should contact the TV's manufacturer. Roku only provides the OS and has nothing to do with the hardware.
