Hi Community users!
Thank you for keeping us updated.
We understand that the black screen issues with your Roku TV are persistent; at this point, we would recommend performing a factory reset with your Roku TV by locating the reset button at the back of the TV, pressing and holding it for 10 seconds.
Let us know if this helps.
All the best,
Janadee
