Thanks for the post.
We would first recommend unplugging your TV for 5-10 minutes then plugging it back in to see if the issue is resolved. If you still aren't able to clear up the issue, please contact your TV's manufacturer directly to report this issue and request additional support. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
You can reach TCL here: https://support.tclusa.com/televisions or at 1-877-300-8837.
Thanks,
