Thanks for the post.
If the remote that came with your Roku TV has a headphone jack, it's possible that it may be a faulty remote.
Have you tried contacting your Roku TV manufacturer support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
