ByKevin Wood Updated on20 October 2022
why does my tv sound keep cutting out

Like other home electronics, televisions are subject to failures, and why does my TV sound keep cutting out is one of the myriads of issues TV owners have to deal with.

Most TV manufacturers are good at what they do, and it’s scarce to have an audio problem that causes the sound to keep cutting out.

Your TV sound is cutting out because of a faulty cable, software problem or channel problem. All these three issues can be tackled differently and resolved relatively quickly without spending too much time or money.

This is a detailed article that elaborates the various reasons your TV has intermittent sound and has a step-by-step guide on how to fix such sound glitches.

Reasons Why TV Sound Keeps Cutting Out

Your TV has to have excellent sound to fully enjoy the shows, movies, or songs you are watching.

Here are some of the probable reasons why your TV sound keeps cutting out:

1. Wires

It’s not uncommon to confuse or mess up wire plugging, affecting the TV sound. Damaged wires will also often affect the quality of TV sound.

2. Stereo Receiver

If your TV is connected to a stereo receiver that’s not working, you should expect the sound to keep cutting out because of obstructions.

3. Electronic Devices

Where you place your TV matters a lot. Smart TVs, in particular, are susceptible to electronics that may create signal interference which will cause the sound to cut out periodically.

Remember that your TV sound issues could also be caused by speakers going wrong or being damaged mechanically.

Typically, TV sound cutting out often happens because of a TV Box issue or a cable issue.

But there is more to the problem because sound systems are susceptible to both software and hardware faults.

Here are the different viable solutions for TV sound cutting out to get your TV sound working again.

Solution #1 Unplug All Wires then Plug Them Back

If you’re using a Smart TV, it’s probably connected to other devices to enhance your experience.

While you may be wondering why does the sound keep cutting out on my TV, these secondary devices may have cable problems which may be the reason for the sound hitches.

It would be best to consider unplugging the cables then plugging them back to fix the sound issues.

Here’s how to do it:

  1. Disconnect the power cable from your TV.
  2. Disconnect coaxial wires.
  3. Disconnect all home theatre wires.
  4. Unplug all cables to the stereo receiver.
  5. Unplug all cables from the A/V receiver.

Once you reconnect the cables to their correct ports, you should restart your TV first to fix the sound.

Solution #2 A Cable Channel Problem

Programming errors also occur, and they are often limited to different geographical locations.

  1. Isolate the channel.
  2. Disable Secondary Audio Programming (SAP).
  3. Ensure the coaxial cable is hand-tight.
  4. If it doesn’t work, ensure you contact your cable provider.

Check the audio settings on your television. If you have connected the tv to the external sound system, check that the audio is set to stereo.

Note: In case you have sound on most channels, but TV sound keeps cutting out on some or all of your local network channels, you may be able to fix the problem by turning off the Secondary Audio Programming.

  3. Select Advanced system settings.
  4. Select Factory Reset.
  5. Choose Factory reset everything.

When your TV sound keeps cutting out, it could be a firmware problem.

Most TVs run on Android OS, and like other Android devices, you have to update the firmware to keep your television up to date.
