Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
I'm not sure what you mean by "set up option". Could you be more specific?
Also, a TV from 1986 is from before HDMI. Current models of Rokus are HDMI-only. However there where older Roku models with a composite connection. Which Roku do you have and how have you connected it?
