Hi Candy8795
Thanks for the post.
Have you tried re-pairing the remote to your Roku TV? We suggest giving it a shot.
Check out this link if you need instructions with the suggestion above: How do I resolve issues with my RokuĀ® voice remote?
However, if the issue persists after the troubleshooting steps above, we would recommend reaching out to the TV manufacturer's support team to report the issue and for further help. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
For a list of Roku TV manufacturers contact information, visit our Community post here: Contacting Support for Your Roku TV
All the best,
Kariza
