This can't be the solution. The Roku remote only uses IR to control the TV power and volume. It uses an RF signal to control the Roku itself. No line of site needed.
I would really rather have someone from Roku respond to this post with a real solution to the problem.
Thanks for the post.
Can you please provide more information about the issue you are experiencing?
With more information we will be able to assist you further.
Thanks,
Danny
Me2; resetting the remote made it normal again
