Hello! @Dgerda1980,
A cheerful welcome from the Roku Community!
We appreciate you reaching out to us about your Hisense Roku TV. We're pleased to assist.
If you have tried a system restart, network reset, and factory reset, but your Roku TV™ system continues to be unresponsive, you can use Recovery Mode to try and restore normal operation. Recovery Mode is a feature supported on some models that allows you to clear all data and software from your TV and reinstall the operating system.
For more help with less invasive methods, learn how to system restart or factory reset your Roku TV system.
Please keep us posted on what you find out; we will happily continue assisting you further. We look forward to hearing back from you.
Thanks,
Arjiemar
