Hi @blueayres65,
Congrats on your first post in the Roku Community!
We understand you have a query about the overheating message. Does the issue only occur on a specific channel or across other channels installed on your Roku TV? If the overheating message pops up regardless of the channel you are accessing, we recommend contacting TCL support directly to report the issue and for further help. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
Please keep us posted!
All the best,
Chel
