What make/model Roku TV do you have? They are not all identical, so we need to know the details of what it might have.
I am assuming you are looking for analog inputs. That would be three connections, colored red, white and yellow. Red and white are the audio jacks and the yellow is video. Not all TVs have such connections anymore, and with some TVs you might have a adapter cable that provides the three connections on the end of a short cable with a single plug that connects to the TV.
