Hi @Shwebik,
Greetings from the Roku Community!
If you're having trouble with a Roku TV made by a Roku partner, start by contacting the maker. Each television manufacturer offers direct assistance for its models. You can contact them via Hisense customer service.
Please feel free to let us know if you need any additional assistance!
Kind regards,
The Roku Community Team
