How to Fix No Sound in Sony TV:
Initial Checks
Before diving into more complex solutions, it’s essential to perform some basic checks to ensure the issue isn’t caused by a simple oversight. These initial checks can often resolve the no sound problem in your Sony TV quickly and easily.
Check the Volume
The first and most obvious step is to check if the volume is turned up. It might seem trivial, but sometimes the simplest solution is the correct one.
- Use the volume up button on your TV remote to increase the volume.
- Look for the volume indicator on the screen to ensure it’s not set to zero or mute.
If you see the volume increasing on the screen but still don’t hear any sound, move on to the next check.
Verify the Mute Function
Sometimes, the TV might be accidentally muted, causing the no sound issue.
- Look for the mute button on your Sony TV remote. It usually has a speaker icon with a line through it.
- Press the mute button once to unmute the TV if it’s currently muted.
- Check if the sound returns after unmuting.
Ensure Power Connections
While it might not seem directly related to sound issues, proper power connection is crucial for all TV functions, including audio output.
- Check if the TV’s power cord is securely plugged into both the TV and the wall outlet.
- If you’re using a power strip or surge protector, make sure it’s switched on and functioning correctly.
- Try plugging the TV directly into the wall outlet to rule out any issues with the power strip.
Restart Your Sony TV
A simple restart can often resolve temporary glitches that might be causing the no sound issue.
- Turn off your Sony TV using the power button on the remote or the TV itself.
- Unplug the TV from the power source.
- Wait for about 1-2 minutes.
- Plug the TV back in and turn it on.
- Check if the sound has been restored.
Check TV Settings
If the initial checks didn’t resolve the no sound issue in your Sony TV, the next step is to dive into the TV settings. Sometimes, incorrect audio settings can cause sound problems.
Audio Output Settings
Your Sony TV might be set to output audio to an external device instead of its built-in speakers.
- Press the ‘Home’ button on your Sony TV remote.
- Navigate to ‘Settings’ or ‘Setup’ (the exact name may vary depending on your TV model).
- Look for ‘Sound’ or ‘Audio’ settings.
- Find the ‘Audio output’ or ‘Speakers’ option.
- Ensure it’s set to ‘TV speakers’ rather than ‘Audio system’ or ‘External speakers’.
Sound Mode
Incorrect sound mode settings can sometimes cause audio issues.
- Go to the ‘Sound’ or ‘Audio’ settings as described above.
- Look for ‘Sound Mode’ or ‘Audio Mode’.
- Try different modes like ‘Standard’, ‘Cinema’, or ‘Music’ to see if it resolves the issue.
- If you find a mode that works, you can keep it or continue troubleshooting to fix the other modes.
Digital Audio Out
If you’re trying to get sound from an external device connected via digital audio out, check these settings:
- Navigate to ‘Sound’ or ‘Audio’ settings.
- Look for ‘Digital Audio Out’ or similar option.
- Ensure it’s set to ‘Auto’ or ‘PCM’, depending on your connected device’s compatibility.
Advanced Audio Settings
Some Sony TVs have advanced audio settings that could potentially cause sound issues if set incorrectly.
- In the ‘Sound’ or ‘Audio’ settings, look for ‘Advanced settings’ or ‘Expert settings’.
- Check options like ‘Dynamic Range Control’, ‘Dialogue Enhancement’, or ‘Volume Offset’.
- Try turning these options off or adjusting them to see if it resolves the sound issue.
Verify External Device Connections
If you’re trying to get sound from an external device connected to your Sony TV, it’s crucial to verify these connections. Improper connections can often lead to no sound issues.
Check Cable Connections
Loose or faulty cable connections are common culprits for audio problems.
- Inspect all cables connected to your TV, including HDMI, optical, and analog audio cables.
- Ensure each cable is securely plugged in at both ends.
- If possible, try unplugging and re-plugging each cable to ensure a good connection.
- Look for any visible damage to the cables, such as frays or bends.
Verify HDMI Connections
If you’re using HDMI to connect devices like a cable box, game console, or Blu-ray player:
- Check that the HDMI cable is plugged into the correct HDMI port on both the TV and the external device.
- Try switching to a different HDMI port on your TV to rule out a faulty port.
- If possible, try a different HDMI cable to eliminate the possibility of a faulty cable.
Test with Different Devices
To determine if the issue is with your TV or the connected device:
- Try connecting a different external device to your TV.
- If you get sound from the new device, the problem likely lies with your original device or its connection.
- If you still don’t get sound, the issue is more likely with your TV.
Check External Device Settings
Sometimes, the connected device might be the source of the audio problem.
- Ensure the external device is powered on and functioning correctly.
- Check the audio output settings on the external device. It should be set to output audio via HDMI or whatever connection you’re using.
- If using a cable or satellite box, try changing channels to see if the audio issue persists across all channels.
Update TV Software
Outdated software can sometimes cause audio issues in Sony TVs. Keeping your TV’s software up-to-date can resolve many problems and improve overall performance.
Check Current Software Version
Before updating, it’s good to know your current software version:
- Press the ‘Home’ button on your Sony TV remote.
- Navigate to ‘Settings’ or ‘Setup’.
- Look for ‘System Information’ or ‘About’.
- Note down the current software version.
Enable Automatic Updates
Sony TVs can be set to update automatically, which is the easiest way to keep your software current:

Test Internal Speakers
If the TV has a speaker test function, use it to check if the internal speakers are working:
- Go to ‘Sound’ or ‘Audio’ settings.
- Look for ‘Speaker Test’ or ‘Test Tone’.
- Run the test and listen for sound from each speaker.
- If you don’t hear sound from all speakers, there might be an issue with the speaker system.
Check Audio Formats
Ensure your TV supports the audio format of the content you’re trying to play:
- Go to ‘Sound’ or ‘Audio’ settings.
- Look for ‘Audio Format’ or ‘Digital Audio Out’.
- Set it to ‘Auto’ or ‘PCM’ if you’re unsure about compatibility.

- Look for ‘Advanced Settings’ or ‘Expert Settings’.
- Try disabling features like ‘Surround Sound’, ‘Equalizer’, or ‘Sound Enhancement’.
- Test the audio after each change to see if it resolves the issue.
Check for Hardware Issues
If software troubleshooting doesn’t resolve the no sound issue, it’s time to consider potential hardware problems.
Inspect TV Speakers
Physical damage to TV speakers can cause sound issues:
- Visually inspect the speaker grilles for any visible damage.
- Gently touch the speaker areas while audio is playing to feel for vibrations.
- If you notice any rattling or lack of vibration, there might be a speaker problem.
Check Headphone Jack
If your TV has a headphone jack, it could be causing the issue:
- Check if anything is plugged into the headphone jack.
- If so, remove it and see if the TV speakers start working.
- If nothing is plugged in, try inserting and removing headphones a few times to clear any potential debris.
Test with External Speakers
Connecting external speakers can help determine if the issue is with the TV’s audio output:
- Connect external speakers or a sound system to your TV.
- If you get sound through the external speakers, the TV’s audio output is working, but there might be an issue with the internal speakers.
- If you don’t get sound, the problem might be with the TV’s audio processing or output.
Look for Physical Damage
Inspect your TV for any signs of physical damage that could affect audio:
- Check for any cracks or dents on the TV body, especially near speaker areas.
- Look for any signs of liquid damage or corrosion.
- Ensure there are no objects obstructing the speaker grilles.
Reset TV to Factory Settings
If all else fails, resetting your Sony TV to its factory settings can often resolve persistent audio issues. However, this should be a last resort as it will erase all your custom settings and installed apps.
Backup Your Settings
Before resetting, try to backup your settings if possible:

- Reinstall any apps you previously had.
Test Audio
Once the setup is complete, test the audio:
