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.
When you say TV programs are playing, sounds like you mean your TV is playing OTA/antenna programs and you are not seeing the Roku Setup or Home Screen. Try using your TV remote (not the Roku remote), and selecting the HDMI port that the Roku device is plugged into. (look for a button on your remote that says Input or similar).
