Thanks for posting in the Community!
To make sure we're on the same page, is your Roku TV not responding to any buttons pressed on your remote? You can try re-pairing the remote and performing other remote troubleshooting steps available on this link: How do I resolve issues with my Roku® voice remote?
Moreover, you can use the Roku mobile app as a remote so you can still navigate on your Roku interface while you're having issues with your Roku TV remote.
We look forward to hearing from you soon.
All the best,
