Make sure you enable the correct HDMI input under the RokuTV settings (Settings/TV Inputs) using the RokuTV remote. Then select that input from the RokuTV Home Screen. (again, using RokuTV remote).
Once you see your Roku streaming device's Home Screen appear, then use your Roku device's remote (not the RokuTV remote) to go to Settings/Network/Setup Connection and connect your device to the network.
Post the model number of your Roku device if still having issues.
