A warm welcome here in the Roku Community, @SugarBell1965!
Thank you for reaching out regarding the issues you're currently experiencing on your TCL Roku TV. I'd be happy to help you contact the right support.
In cases like this, it may be possible that this is a hardware failure. I highly recommend directly reporting this case to your TV manufacturer which is TCL. They are responsible for their hardware operating system and can further assist you.
