Before we can fix the problem, we need to identify the source of the humming sound. To do this, try the following steps:
- Turn off your TV and unplug it from the wall.
- Disconnect any external devices, such as gaming consoles, Blu-ray players, or soundbars.

Common Causes of TV Humming and How to Address Them
There are several common causes of TV humming, including:
- Loose or damaged cables: Check all cables connected to your TV for any signs of damage or loose connections. Replace any damaged cables and ensure all connections are secure.
- Faulty internal components: If the humming sound is coming from the TV itself, it could be due to a faulty internal component, such as the power supply or speakers. In this case, you may need to consult a professional technician.
- Electrical interference: Nearby electrical devices or wiring can cause interference, resulting in a humming sound. Try moving your TV away from other electrical devices or re-routing any nearby wiring.
The Role of Grounding in Eliminating TV Humming Issues
Proper grounding is essential for eliminating TV humming issues. A poorly grounded TV can cause electrical interference, resulting in a humming sound. To ensure your TV is properly grounded, check the following:
- Make sure your TV is plugged into a grounded electrical outlet.
- If you’re using a surge protector or power strip, ensure it’s also properly grounded.
- Check your home’s electrical wiring for any grounding issues and consult a professional electrician if necessary.
Troubleshooting Power Supply Problems to Fix a Humming TV
A faulty power supply can cause a humming sound in your TV. To troubleshoot power supply issues, try the following:
