Thanks for the post.
When you say the correct channel, are referring to the correct HDMI input? Have you tried replacing the HDMI cable used to connect the device?
For troubleshooting purposes, have you tried to connect your Roku device to another TV to see if you are experiencing the same issue?
With more information we will be able to assist you further.
Thanks,
