Apple tv app freezing on new tcl tv

Is that on the Google TV platform, or a different OS for apps?

• Verify that the TV system software/firmware is up-to-date. Install a newer version, if available.
• Try deleting the Apple TV app, then reinstall, and sign in again.
• Try a cold restart of the TV (through the menu or disconnect from power; not just standby-wake).

If the issue persists after that, then contact the Apple Support staff for further assistance.

Unplugging the tv actually worked…

Thanks for your follow-up. Excellent, sometimes the old remedies* just do it. Enjoy!
