Why is my Smart TV not recognizing any of my HDMI inputs?

1. Check all cables. Be sure to double check that both ends of your HDMI cables are securely plugged into your devices and the TV.
2. Confirm TV source or input setting. Use your TV’s remote or physical buttons to make sure the ‘source’ is set to the input you are trying to use.
3. Check for Firmware Updates. Connect your TV to the internet to search for and install any available firmware updates.
4. Perform a Power Cycle. Turn off your TV and unplug any HDMI cables or other devices. Let the TV remain unplugged for 2 minutes before plugging everything back in.
5. Call Tech Support. If none of the steps above have resolved the issue, contact your TV manufacturer’s technical support team.
