Welcome to the Roku Community!
I understand that you are inquiring about a replacement remote for your Roku TV.
If you need a replacement remote or information for a Roku TV remote, you would need to contact your TV manufacturer. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
You can reach them here: TCL Support or at 1-877-300-8837.
You can also purchase a remote that is compatible with your Roku TV here: Roku Accessories | Streaming Accessories for Roku Devices & TVs | Roku
In addition, please be aware that we can't guarantee partner buttons, the channel shortcut buttons vary even on the same Roku models.
I hope I have addressed your question appropriately, let us know in case you've still got any questions.
