Hi @Taurus17,
Welcome to the Roku Community!
Thanks for posting and we'd be happy to take a closer look to see how we can help get you up and running.
Can you please verify if the issue only occurs on Live TV or all channels on your Roku device?
If you are having an issue with your Roku TV screen going black but can still hear the audio, customers have reported that unplugging your device for 5-10 minutes and then plugging the Roku TV back in resolves the issue.
Please keep us posted and we'll continue assisting you from there.
Best regards,
Mary
