Thanks for the post.
Having you tried using another HDMI input on your TV as well as switch the HDMI cable used to connect the Roku device to see if that resolves the issue?
For troubleshooting purposes have you tried plugging in the Roku device into another TV to see if you are experiencing the same issue?
Please keep us posted what you find out.
Thanks,
Danny
