In this article, we will share with you several ways to fix your TV with no sound when it is not muted.

These are most of the common fixes to the most common sound problem you can experience with your TVs. 

Why Do I Suddenly Have No Sound on My TV?

Six Ways to Fix a TV That Has No Sound But Is Not Muted

There are several reasons your TV would suddenly have no sound, either due to an incorrect setting or a wrong HDMI. 

From research, some of the commonest reasons why your TV suddenly has no sound include; 

  • Very low volume on your TV or external speakers. 
  • You are incorrectly configuring your sound settings. 
  • Improper connection of the soundbar or external speakers. 
  • Hardware failure of the internal components of your TV. 

You can fix some of these problems by yourself, but other times, you would need to call on a professional for help. 

Either way, ensure that you do the right work, so you do not have to spend on the same problem twice in a short while.

7 Ways to Fix a TV That Suddenly Have No Sound 

Some ways you can fix your TV that has no sound include; 

#1. Checking the Volume 

This fix may sound funny, but this is most likely the problem. So before panicking, ensure that you check for this issue. You can fix this problem by increasing your TV volume, and you’re already. 

If the audio settings are a problem, ensure that you do not open up the TV, as that may lead to further complications. 

So before taking any other step, you should first take your remote and check if you have increased the volume. 

#2. Checking for a Headphone Jack 

Checking for the headphone jack is another simple way you can fix your TV’s sound issue.

A lot of TVs come with a head pot back for your headphones. If you plug a wire in, the TV won’t play audio you can hear.

So, you must put on your headphones to hear the sound, if it is connected, or better still, disconnect your headphones from your TV. 

Another issue now is how to find your headphones jack. Unfortunately, this question doesn’t have a definite answer because it depends on the model of your TV. 

Generally, the TV headphone port is located at the back or side of your television. 

#3. Checking Your Connection Cables 

So, the next issue is your cables. After confirming that the issue is not from your headphone jack and the volume is not on mute. 

This one can be kind of tricky because there are several types of cables that you would need for your TV’s audio.

These cables are the following; 

  • HDMI cables. 
  • Phono cables. 
  • Optical cables. 
  • Auxiliary cables. 
  • Coaxial audio cables. 
  • SCART cables. 
  • Component connections.

These are not all the cables, and if you connect your TV to external speakers, then there would be more cables you would need to evaluate. 

So, to check for cable issues, you should be on the lookout for damaged ports, damaged cables, and a firm connection with the cables. 

You must unplug everything from your TV port to fix cable connection issues and securely reconnect them. Testing for a damaged HDMI cable is not as easy as checking for other cables.

To test for your damaged HDMI cable; 

  1. Go to settings and click on support. 
  2. Keep scrolling down until you see an option that says self-diagnosis. 
  3. Tap signal information, select HDMI cable test, and choose start test. 

After they run the test, the system will inform you if your HDMI cable is the one with the problem or not.  The best way to solve this problem is to contact a professional for help. 

#4. Check Your Internal and External Speakers

If your TV still has no sound after doing all the above, it is high time you give the internal and external speakers a check. 

Your internal speakers can get damaged for two major reasons; too much pressure and using a more powerful amplifier than your speakers. 

When you’re always blasting music from your TV speakers at full volume, your internal speakers are most likely to develop a fault. 

It also relates to using a more powerful amplifier than your speaker can take in. so when the amplifier gives off too much sound, you push the speakers past its limits. 

To check if your internal speakers are damaged; 

  • Get your remote and go to the audio menu. 
  • Locate the pan control, and pan left first, and check if you hear a sound. 
  • After that, you can pan right to check if there is a sound. 

If you hear no sound from both sides at the end, you need to replace your internal speakers and check your extremal speakers to see if they were unaffected. 

Unlike the internal speakers, checking your external speakers for faults can be very tricky as it depends on the TV model you use. 

#1. For a sonny TV: 

  1. First, set the control for your HDMI and TV to “on.” 
  2. Set the audio return channel on your audio system to “on.” 
  3. On your TV, set the output destination for your audio to “audio system.” 
  4. Press the input or TV button on your remote audio control system. 
  5. Turn your TV and audio systems on.

#5. Changing the Channel

As funny as it might sound, changing the channel you are watching can fix this issue. 

The problem is not mainly from your end in every case; sometimes, the problem might be from the channel you’re watching. 

You can do a simple test by changing the channel to see if other channels have sound and then come back. 

This issue is mostly temporary, so you must keep enjoying other channels until the sound on that channel is restored. 

#6. Restart Your TV 

If none of these options seem to be working, don’t worry; you have another solution that has fixed a lot of TVs in the past; restarting. 

Restarting your TV helps to refresh the settings, including the sound settings. Therefore, there is a high chance that this solves the issue. 

Restarting your TV depends on the model you use, but there’s a general way people restart most TVs. These are;

  • Disconnect all cables and connections from the TV and unplug your TV. 
  • Replug your TV and power it back on. 
  • Wait for your TV to reboot and check out for the sound again.

  2. Search for any updates for your TV software. Then, download it on your computer and transfer it to a flash drive. 
  3. Plug in that same flash drive to your TV and download the updated version on your TV. 

After doing this, you should be able to hear the sound again.
