There are a few steps you can take to troubleshoot issues you may be experiencing with your Smart TV:

1. Restart your TV. Unplug the power cable from the back of the TV and keep it unplugged for about 5 minutes. Then plug it back in and turn the TV on.
2. Check that your TV is updated. The updated version of the TV’s software will have the latest troubleshooting features.
3. Check for any loose cables. Make sure all cables connected to the TV are securely plugged in.
4. Check your power settings. Verify that the power settings are enabled, as some models have settings that can cause the TV to shut off automatically.
5. Check your TV’s energy saving mode. Make sure this mode is off or set to moderate.
