Hi @Taaron12,
Welcome to the Roku Community!
If you are having an issue with your Roku TV screen going black when playing content on the YouTube channel, we recommend unplugging your device for 5-10 minutes then plugging the Roku TV back resolves the issue.
In addition, Have you tried removing any unused channels from your Roku device including the Youtube channel, restart your device, and then try to add the Youtube channel back to see if you are still experiencing the issue you are seeing?
Lastly, what are you seeing on screen? Can you provide a video of the issue you are experiencing?
We look forward to hearing from you and looking closely into this issue. Thank you!
Best regards,
Mary
