No sound on Sony TV – causes of this problem
If you’re having a hard time pinpointing the cause of no sound on your Sony TV, we’d be happy to help. Here is a comprehensive list of reasons why your Sony TV may be experiencing audio issues:
Obvious reasons
Most of us are familiar with the common troubleshooting techniques used in any technology related field. The “off and on”technique is obvious.
This often works and solves most problems with your device. So we recommend starting with it. If it doesn’t work, try the following points:
- Mute setting
Your TV may have the mute function enabled.
Or, your TV’s volume has become very low, and this may cause your Sony TV to look like it’s not working.
While almost every TV model shows the word “MUTE”displayed on the TV screen, some do not. So, check if your TV is turned off.
- Extremely low volume
It’s also possible that your TV’s speakers have failed over time. This can cause your TV’s normal volume level to be much lower than normal.
You need to try turning up the volume for the sound to be heard.
- Free connections
If your connection cables are loose, it may interfere with the sound of your TV.
Also, if the connecting cables or port contain a lot of dust or debris, this may be the reason why your TV is not working properly.
You need to make sure that your TV and all other devices (stereo, HDMI, etc.) connected to it have secure connections. Also, check the wires for wear.
Other possible causes
If you got to here, then the obvious reasons did not help much in your case. Don’t worry; Here are a few more steps you can try:
- Streaming device issue
Your streaming device, such as an Amazon FireTV flash drive, Blu-Ray player, or any other satellite dish, may be malfunctioning.
For example, you are watching a TV show with
device such as Fire TV. In this case, check the device settings to make sure that the sound is output only through the speakers of your Sony TV and not elsewhere.
- Check if the TV speakers are turned on
Sometimes the Sound/Audio section of your TV settings is set to something other than Sony speakers.
To check this, go to the “Sound/Audio”section of your TV’s settings and see if it reads “TV Speakers”, “Sony Speakers”or something similar.
Otherwise, the TV will not know where the sound should be played.
- Incorrect audio input setting
Your TV may be set to play sound from a different speaker.
Or you probably had a headset plugged into your TV, which could have changed your TV’s default audio settings.
- hardware problem
It is also possible that your TV’s internal hardware is damaged or malfunctioning. It can also affect the sound quality of your TV. Also, if you only use your TV’s built-in speakers.
They too could be damaged; hence your TV sound is limited.
- Damaged software
It is also possible that your Sony TV software is corrupted or outdated. In this case, your TV will not be able to work normally.
You will need to reset or reboot it in order to update the TV software. Or you may need to update it to get rid of current data on Smart TV.
How to Fix No Sound Problem on Sony TV – 5 Solutions
If your Sony TV was not playing sound, apply the following fixes one by one until your TV sound issue is resolved:
- Try unplugging the TV from the wall
- Disconnect the power cord from the back of the TV
- Update your Sony TV software
- Reset sound/sound settings on Sony TV
- Restore your TV to factory settings
Solution 1: Try unplugging the TV from the wall
This probably sounds like a no-brainer to you, but many people forget to try it. Unplugging the TV from the wall outlet is a common way to try and restore TV sound.
So, you must unplug the TV from the wall outlet and wait 60 seconds. Then plug it back in after waiting 1 minute.
Also, hold the Sony TV plug for about 30 seconds. This should help drain the TV’s residual power and the TV will automatically reboot.
This is different from simply turning the TV on and off with the remote control.
Many users report that this has worked for them. However, sometimes it can be a little tricky. If you are still struggling with no sound issue on your Sony TV, try the following fixes.
Solution 2 – Disconnect the power cord from the back of the TV
This is another easy way to fix your TV. All you have to do is unplug your TV’s power cord from the back of your TV and leave it there for about 60 seconds. Then reconnect it.
After you have connected it, make sure the connection is tight and secure. If the connection is poor, it may cause your TV not to get enough power. When the power cord is securely connected again, turn on the TV with the power button, not with the remote control.
This should fix the no sound issue on your Sony TV and you should be able to hear sound from the TV again. If not, then move on to the next solution.
Solution 3: Update your Sony TV software
If you are using an older version of Sony software on your smart TV, this may cause several problems.
Ideally, your Sony TV should download the latest software on your behalf. But sometimes this may not happen.
In this case, you just need to make sure that your TV software is always up to date.
Once the software update is complete, your TV’s AV settings should be reset to their original defaults. Follow the instructions below to update your Sony TV software:
- Press the Home button on your Sony TV remote control.
- Choose Help > Status & Diagnostics.
- Select System Software Update.
- Your TV will now start looking for the latest software update. If an update is available, the TV will display instructions to download and install it.
Solution 4: Reset sound/sound settings on Sony TV
This is another way to solve the problem of no sound on Sony TV. We need to reset your TV’s audio/sound settings.
To do this, follow the steps given below:
- Press the Menu button on the TV remote.
- Continue down the TV menu list using the arrow keys until you find “Settings”.
- Select “Settings”and then “Settings”.
- Navigate to the “Sound”option and select “Reset”.
- Press the OK button on the remote control. This should reset your TV audio settings to factory defaults.
Sometimes the original sound settings can create problems with your TV’s sound system.
Issues such as Sony TV volume not increasing or decreasing properly.
If you can’t detect the change in volume, try pressing the mute button to make sure the TV isn’t muted.
Now check if there is a cable in the audio jack. External cables or headphone wires will carry the sound from the TV speakers to the external cable system. So, unplug your external sound systems from your Sony TV.
The next step is to go to your TV’s Settings menu and look for the Headphone/Audio Out option.
Set it to Audio Out if it’s not already set to that. Now go to your MTS settings and use “Basic”or “Stereo”as your main option.
Another thing to do is check the main menu and turn on the speakers. This will activate the speakers.
The two audio settings above should help you make sure your speakers are your main audio source, as well as fix the problem if it’s not hardware related.
Solution 5: Factory reset your TV
A factory reset can restore the TV’s default settings. To do this, follow the steps given below:
with remote control
- Press the Home button on the TV menu.
- Select “Settings”from the TV menu and then “Customer Support”.
- Select the “Storage and Reset”option.
- Then select Factory Data Reset.
- Finally, choose Erase Everything.
- After that, restart your TV and check if the sound works.
Note. Keep in mind that this will cause your TV to lose its previous custom settings, but everything, including sound features, will revert to a normalized version.
Without remote
There are certain buttons on your TV that will help you restore factory settings. Also, you need to check your TV model.
Based on this, you will be able to find the buttons to reset the TV.
These buttons can be located on the left, right, bottom, or even under the TV.
You need to connect the TV to the network and press the reset button. But the procedure may differ for different models of Sony TVs.
Final Thoughts
In case the last resort i.e. factory reset also failed to resolve the “Sony TV no sound” issue, this indicates that your TV’s audio cables and speakers likely have a problem that can cause malfunctions in sound work.
If this is a problem, please contact the customer support channels. Your TV’s audio system may have failed, and if you’re under warranty, you can get a replacement through Sony.
