Hi @ShariC1961,
Welcome to the Roku Community!
Can you please provide us with more information? What model Roku device are you using? Are there specific channels that you are having this issue with? How are you powering the Roku device? Is the device plugged into the TV USB port or is it plugged into a wall outlet?
With more detailed information, we will be able to assist you further.
Warm regards,
Lianna
