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 we got the TV my fiance was messing with it and somehow deleted the app that comes pre-installed on the TV and we can't find a way to put it back on. Any help?
I'm assuming you are talking about The Roku Channel.
If so, go to Streaming Channels > Search Channels
Enter "ROKU" in the search box.
If The Roku Channel doesn't display, then there are some concerns, beginning with where are you? The US? Another country? Not all apps are supported in all regions, and that includes the Channel Store.
