Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
We're very sorry to hear of the troubles and I'd be happy to help.
Have you tried performing a factory reset on your Roku TV to see if that resolves the issue you are experiencing?
For more information about how to perform a factory reset, visit our Support page here: How do I factory reset my Roku® streaming device?
Keep us posted and we'll continue assisting from there if needed.
