Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
When I watch the Roku channel on my stand alone roku device, I am able to go the "live tv", select a channel and press the back arrow button to get the guide. However, when I do this on my TCL Roku TV, nothing happens when I press the back arrow button.
What software version is on each device from Settings->System->About? If one is on v9.2 and the other is on v9.3 that could explain it Or, what version of The Roku Channel do you have on each one? Press the asterisk button * when you have the channel highlighted on the home screen to find out.
