  2. 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:

  1. 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.
