Why does my TV suddenly have no sound?

If your TV does not have any sound, it might be due to your TV’s audio settings or your connected speaker’s/audio output settings.

You can first check your TV’s audio settings by going to the menu. If you have speakers or other audio devices connected, you can also check if they are properly turned on and connected to your TV. Your speakers’ volume may also be turned down low.

Remove the Sony TV from the power socket.

While it may appear obvious, unplugging your Sony TV from the electrical outlet is the most common method for regaining sound. The key is to wait for the whole 60 seconds. Allow at least a minute to pass before plugging it back in.

While your Sony TV is turned off, locate and press the power button for 30 seconds. Make sure you’re holding the power button on your TV rather than the remote.

This helps to reduce the TV‘s remaining power and allows it to soft reset itself. But while this technique should work in around 80% of cases, the other 20% may prove to be more problematic.

If the sound on your Sony TV is still not functioning, try the remedies suggested below.

Before removing the Sony TV from the power socket, it is crucial to prioritize safety. Ensure that the TV is turned off and in standby mode to avoid any electrical hazards during the disconnection process.

Reinstall the power cord at the rear of the Sony television.

Another easy potential option is to disconnect the power cord from the back side of the TV. Disconnect it for approximately 60 seconds before reconnecting it.

When you plug it back in, ensure the connection is secure. A firm connection is required to ensure that the TV gets consistent power.

Plug the power cord and switch on the TV to use the power button on the TV rather than the remote. Perhaps, you’ll see the TV turn on and hear the sound again.

When you’re out there resetting the power cord, disconnect and reconnect all TV connections.

After reinstalling the power cord, take a moment to organize the cable to avoid tangling or tripping hazards. Proper cable management helps maintain a neat and clutter-free setup.

Update the System Software on Sony TV

Using older versions of Sony software on your TV may cause a variety of problems. Normally, your TV will install the most current edition for you automatically.

However, this doesn’t always happen. Just make sure the software on your television is kept up to date. You may find detailed instructions for doing so here.

After the software update is completed, both your visual and audio settings may well be reset to their defaults. It’s also possible that your TV has gone deaf as a result of automated software updates.

To test whether this is the issue, I would disable software updates for a time and see if that addresses your problem.

To disable automatic software updates, follow these steps:

On your remote, hit the Home button.
Choose Settings, then Customer Support.
Scroll all the way down to Automatic Software Download.
Turn it off.

If this fixes your problem, you’ll only have to remember to manually check for software updates to keep things up to date.

System software updates can take some time to download and install, depending on the size of the update and your internet connection speed. It is important to be patient and avoid interrupting the update process to ensure a successful installation.

The Sony TV’s audio/sound settings must be reset.

Resetting the audio/sound settings on your Sony TV is yet another option for correcting sound issues

For example, on a Bravia Smart TV:

Just use the remote to select Menu.
Go to Preferences, then Settings.
After selecting “Sound”, choose Reset. Select OK.

This will revert your Sony TV’s sound settings to factory settings. If that doesn’t work, it’s time to reboot your TV’s settings to factory defaults.

Sony TVs often come with advanced audio features, such as Virtual Surround Sound, ClearAudio+, or Dolby Atmos support. After the reset, you can explore these features and enable/disable them based on your audio preferences and content being viewed.

How do I reset my Sony TV settings?

A factory reset effectively returns your Sony TV to the configuration it had on the date you bought it. You can check your TV’s menu and then Network Settings to facilitate the reset of your Sony TV.

Choose “Settings” from the menu.
Simply select “Storage and Reset.”
Click “Factory Data Reset.”
Finally, choose “Erase Everything.”
Restart your television to test the sound.

It’s important to note that resetting the TV settings does not affect channel or input configurations. You won’t lose your channel presets or connected device settings during the reset process.

Quick Sound Settings To be Changed

“Dolby Digital Plus” should be changed to “Dolby Digital.”

The first option we’d like to tweak is Dolby Digital Plus Output.

Go to Home, then select Settings.
Go into Display & Sound and choose Audio Output to do so.
Then, under the Dolby Digital Plus Output menu, select Dolby Digital.

Dolby Digital Plus is widely supported across various devices and platforms, including televisions, Blu-ray players, streaming media players, gaming consoles, and mobile devices. It is a common audio format used in streaming services such as Netflix, Amazon Prime Video, and Disney+.

Disable “Dolby Digital Plus Out.”

Following that, if you have a connected sound bar, stereo receivers, or Bluetooth adapter:

Select Settings/Options on your Sony remote.
Scroll to the bottom and select Audio System instead of Speakers.
Return to the Settings/Options menu, choose Audio Adjustments
Select Advanced Settings, and turn off Dolby Digital Plus Out!

Disable “HD-DOLBY.”

If you’re using a cable connection or a streaming device such as a Roku or an Amazon Firestick:

Navigate to the Menu and disable HD-DOLBY.
Go to Settings
Choose Display & Sounds
Select Audio
Press on Dolby Digital Output
Turn Dolby Digital Plus Off on a Firestick, for example.

Dolby HD supports high sample rates up to 192 kHz, enabling the playback of high-resolution audio content. This ensures that even the most subtle details in the audio are accurately reproduced.

Configure the “Digital Audio Out” option to PCM.

Lastly, if you have a Sony Bravia TV, try switching the Digital Audio Out option to PCM.

To do so:

Press the Home button on your Sony remote.
Select Settings.
Go to Preferences.
Select Setup and then AV Setup.
Choose Digital Audio from the drop-down menu and remove it from the menu.
Substitute PCM for this.
