What list of things would I do?

1. Verify that your TV’s accessories and cables such as the batteries in the remote, the power cable, and the HDMI cable are properly connected and functioning.
2. If not, try replugging the power cable to the TV.
3. Check if it will respond to a Power Reset. On most smart TVs, this can be done by holding down the Power or U+SELECT button for 15-30 seconds.
4. Try holding down the menu button of the TV itself, then press the same button one more time.
5. If the issue persists, please contact your TV manufacturer.
