1. Check for any power-saving options on your Smart TV that could be causing it to turn on automatically.
2. Consider moving other devices away from the Smart TV. This will reduce the likelihood of the TV being affected by electrical interference.
3. Unplug the power cord from both the wall outlet and the TV.
4. Disable the CEC (Consumer Electronics Control) feature on your Smart TV if available.
5. Turn off other devices connected to the same power source as the Smart TV (e.g. Blu-ray or DVD player).
6. Purchase an isolation transformer to reduce potentially harmful electrical surges that may cause the TV to turn on automatically.
