Thanks for the post.
The issue you are experiencing may be related to a hardware issue.
Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
You can reach them here: https://support.tclusa.com/televisions or at 1-877-300-8837.
Thanks,
Danny
