Whether placed in a waiting room or mounted in the employee lounge, the Sony Bravia LCD or plasma TV provides access to high-definition sports, movies, shows and more. If your Bravia starts emitting a buzzing sound through the speakers, it doesn’t always mean the TV is malfunctioning; often, you can fix the problem by adjusting your Bravia’s settings. Sony recommends that you go through a troubleshooting process to correct the buzzing before sending the TV to them for repair.
- Press the “Volume” button on the remote control to turn the Bravia’s volume down. If you set the volume to a very high level, you will hear buzzing through the speakers.
- Press “Menu” on the remote control to view the options screen. Select “Sound” and “Sound Mode.” Choose a different sound mode, such as “Standard,” “Clear Voice” or “Dynamic.” Select “Custom” to adjust the bass, treble and equalizer manually.
- Connect devices to different inputs, if possible. For example, if your DVD player is connected via component cables, try connecting it to the TV with an HDMI cable instead. Press the “Input” button to select the new input on the TV.
- Replace the antenna if you use one to receive high-definition programming. If the antenna is damaged, you will hear audio interference through the speakers.
- Connect the antenna to the Cable/Antenna port on the back of the TV. Make the connection using a 75-ohm coaxial cable. Do not use a 300-ohm coaxial cable. This type of cable is often affected by radio interference that can cause a poor signal and audio problems.
- Move the antenna away from other cords and cables to reduce audio interference.
- Disable SCENE, a feature that automatically adjusts the picture and sound of the TV based on the current program. Press the “SCENE” button on the remote control, then select “General” and “Off.”
