Hi @hnakamura75,
A warm welcome here in the Roku Community!
Thanks for letting us know about this. We'd like to take a closer look at this issue.
Have you tried using a different HMDI cable to see if the problem persists? For troubleshooting purposes have you tried connecting the Roku device to another TV to see if the same issue occurs?
Let us know the details so that we can further look into it.
Regards,
