Sony TV No Sound – Quick Fixes
If the sound is not working on Sony TV, try resetting it. First, disconnect your TV from its power source and wait a full minute. In the meantime, press the power button and hold it for 30 seconds. Once the time is up, reconnect your TV and see if the issue is resolved.
This will “soft reset” your TV and, hopefully, get it back up and running like before.
1. Press the Mute Button on Your Remote
Sometimes you may accidentally press the “Mute” button on your remote and hear no sound on Sony TV. This may sound obvious, but not all TVs show a “Mute” message or icon on their screens.
So, make sure your Sony TV is not muted by pressing the “Mute” button on your remote.
2. Increase the Volume
Sometimes, the speakers of your Sony TV could be damaged but not faulty, which allows you to hear the sound at higher volume settings.
It’s a common issue when your speakers are worn down or old. To test the health of your TV speakers, try increasing the volume to its maximum level and see if you hear any sound.
I tried this first and foremost, but even with the sound maxed, I still couldn’t hear any sound from the TV. So if you don’t hear any sound, like I did, move on to the next fix.
3. Disconnect All Cables and External Devices
If the sound on Sony TV is not working, there may be an issue with your external device. Sometimes, an external device with a built-in speaker can interfere with the sound signals that come out of your TV’s speakers.
As a result, you may hear any sound from your Sony TV.
One of my gaming friends has experienced the same issue. After trying various solutions, nothing seems to be working.
So, he unplugged the Xbox USB cable, and voila! It worked.
Remember that this does not just happen to game consoles like an Xbox or PS4.
It’s best to consider all other external devices like streaming sticks connected to your Sony TV, such as:
Aside from that, make sure your headphones aren’t connected to your TV.
After unplugging all cables and external devices connected to your Sony TV, restart it.
Now, check your TV’s sound to see if it’s working.
If not, move on to the next fix.
4. Check for Broken or Faulty Cables
If the cables connected to your TV are damaged or broken, you may not hear any sound.
Over time, wires and cables become loose or worn out. So, unplug all cables one by one and inspect them thoroughly for damage.
That way, you’ll know whether you need to replace the cable or not. You can easily purchase new coaxial, HDMI, and AV cables online.
After replacing the cables, make sure all cable connections are secured properly.
5. Power Cycle Your Sony TV
If nothing has worked so far, try soft resetting your Sony TV. To do that, unplug your TV from its power source and wait for a full minute.
Make sure to wait a whole minute before plugging your TV back in. Meanwhile, press the Power button on your Sony TV and hold it for 20–30 seconds. This will drain any residual power left inside your TV, allowing the Sony TV to reset itself.
In my experience, I did a soft reset of my Sony TV. Remember that I maxed out the volume beforehand? Well, when I turned the TV back on, the volume was in full blast! Thankfully that meant the sound was working already.
A soft reset can resolve about 80% of common issues; the remaining 20% are trickier. If the volume on Sony TV not working still, try the following fix.
6. Reseat All Cables Connected to Your TV
Before moving on to the next fix, ensure all cables connected to your TV are properly secured. A tight cable connection is essential to providing stable power to your TV.
So, unplug every cable connected to your Sony TV and reseat them back in. Once plugged in, turn on your Sony TV using its power button.
This should fix the “Sony TV no sound but picture” problem.
7. Change the Volume Offset to “Stereo” or “Main”
The volume offset on your Sony TV enables you to adjust the sound levels to a fixed level.
So, if this feature is set to “Automatic,” you don’t have complete control over the TV’s sound.
As a result, this might cause a sound issue on your TV over time. Fortunately, many Sony TV owners have reported that changing the volume offset to “main” or “stereo” resolved the no-sound issue. Here’s how.
- Go to Settings > Sound and click on “Volume Offset” from the menu.
- Now, choose “Dual” and click on either “Stereo” or “Main.”
Make sure to test your Sony TV on both settings to see if it’s audible.
8. Update Sony TV Software
If your Sony TV runs on an old software version, it could trigger a series of issues.
Usually, your Sony TV will automatically download the latest software update when connected to the internet, but sometimes you may have to do it manually.
Here is a step-by-step guide to manually installing the latest Sony software update to ensure your TV is up to date.
After the update, your audio and video settings may reset back to factory defaults.
It’s also possible that you’re experiencing no sound issues due to automatic software updates. In that case, try turning off the automatic updates on your Sony TV and see if that resolves the problem. Here’s how.
- Hit the Home button on the Sony TV remote.
- Go to Settings > Customer Support > Automatic Software Download.
- Disable this setting.
If it solves the no-sound problem, keep in mind that you’ll need to update your TV software from time to time manually.
9. Reset Sound/Audio Settings on Sony TV

For instance, if you own a Sony Bravia, press the Menu button on your remote. Open Settings > Preferences > Sound and choose Reset. Now, confirm your decision by pressing OK.
This will reset the sound settings on your Sony TV to factory defaults.
If you still can’t hear any sound from your Sony TV, it’s time for you to perform a factory reset.

You can still reset your Sony TV to factory defaults if you don’t have a remote.
First, locate the buttons on your Sony TV. The position of buttons may vary from one Sony model to another. You may find these buttons in the center, on the left-hand side, or the right-hand side of your TV.
Once you locate them, unplug your Sony TV. Now, press the Volume Down and Power buttons at the same time. Continue holding these buttons and plug your TV back in.
Remember, make sure you don’t release the button until you see the green light on the LED or the Sony logo on the screen. Depending on the model you own, this may take 30 to 40 seconds.
