Welcome to the Roku Community, @Zulumuppet73!
We'd be happy to look into this further regarding the trouble you've experienced with your Roku TV and thanks for trying the steps to resolve the problem.
Please disconnect the HDMI cable from your source device and the TV and then reconnect to ensure the connection is secure.
If the issue persists, we recommend using a different or new HDMI cable. Connect your source device to a different HDMI port on your TV, and then change the TV input to match the port used.
Feel free to keep us posted on how it works.
All the best,
Chel
