Samsung TV speakers are rattling, buzzing, humming or popping
List of possible causes:
• Loose or incorrect cable connections
• Defective or broken cables
• A defective device connect to the TV (DVD Player, Game Console, etc...)
• A problem with the TV itself
How to troubleshoot your TV
The cables connected to your Samsung TV might be the problem. A loose cable may diminish picture and sound quality and create the humming. Connecting a cable to the wrong port on the back of your TV also may result in audio and video problems. Check if the cables are connected securely into the appropriate jacks to avoid audio noise and distortion.
Although less conclusive than the other possible troubleshooting muting your speakers can determine the source of the problem sometimes.
Press the MUTE button on your Samsung remote control and mute the TV's speakers. If the noise continues it is not caused by the TV's speakers but by an external device or a component in the TV itself.
Determine the source of the noise. If the noise is from the TV then it will require service. If the noise stops it is confirmed that the sound is coming from your TVs speakers. Although this noise could be caused by the external device or the connection wires
Try other troubleshooting to determine if the source of the noise.
If your TV was manufactured in or after 2009 you will have a Self Diagnosis function built into your TV. This can be accessed in the Support section of the Main Menu.
(Menu> Support> Self Diagnostic> Sound Test).
Self Diagnosis will allow you to perform a sound test to test the internal speakers of the TV.If this test passes then your TV's speakers are working properly and the problem is with the connection wires or the external device itself.
Try replacing the wires connecting the external device to the TV or contact the external devices manufacturer for further support.
If this test fails your TV will require service.
Press the SOURCE button on the remote control. Change the channel to determine if the sound is a result of a specific broadcast issue.
If the noise disappears after changing the source, then the problem is caused by the connected device or the cables. Verify input source operation. For example, Disconnect the connecting cables from both the TV and the device, and then reconnect them. Ensure they are connected securely to the properly ports.
If the problem persists after reconnecting the cable, replace the cable or contact the device's manufacturer for further troubleshooting.
If the noise continues after changing the source, then the problem is caused by the TV, and the TV must be repaired.
