Why is there a buzzing sound coming from my Smart TV?

1. Ensure the Volume is Enabled: Check if the volume on your TV is low or muted.
2. Unplug Audio Visual Equipment: Unplug audio or visual equipment connected to your TV, such as sound bars, and see if the buzzing sound persists.
3. Move the TV: Move the TV to a different electrical outlet to see if this resolves the issue.
4. Factory Reset the TV: If the issue is persisting, factory reset the TV and check if the issue still occurs.
5. Service Request: If the factory reset does not resolve the issue, it is recommended to request service.
