6 Reasons Why Your Samsung TV Has No Sound But Not Muted [Easy Solutions]

It’s not just a single time, I have faced this issue with my Samsung TV when it has no sound but is not muted. Indeed, in my previous TV, this problem happened at least once a month.

Actually, it was an issue with the issue with the audio cable. So, when I changed the cable, the probability was gone but not completely. Later on, I figured out some other issues that can also cause this issue.

You must have a quick look at those issues in the previous section. Now is the time to learn about those issues with in-depth solutions.

1. The Volume Or Mute Button Is Stuck

The first thing you should do when your Samsung TV has no sound but is not muted is check the remote. There can be different reasons the mute button of your remote control is stuck and it causes the TV to have no sound.

Here are the possible things that can cause your remote mute button to be stuck.

• Dust, dirt, or debris can gather around the volume and mute buttons on the remote control, and that causes it to produce no sound.
• Frequent use of the volume and mute buttons can lead to wear and tear on the remote control or the TV’s control panel and make it muted completely.
• Liquid spills or accidental contact with liquids on the remote control can also cause button malfunction and make the mute button unresponsive.

How To Fix It:

If you’re experiencing the issue of a stuck volume or mute button on your Samsung TV, there are three things you should examine. The first one is the remote itself, the next one is the TV’s control panel and the last one is the buttons that are not functioning properly.

Inspect The Remote Control

Check your TV remote control for any visible signs of damage. It can have sticky residue or debris around the volume and mute buttons. Carefully remove the batteries from the remote to prevent any unintended signals.

You need to clean the remote’s buttons and the surrounding areas with a soft, lint-free cloth. Using an isopropyl alcohol can be necessary as well. Just try to make sure that the remote is completely dry before reinserting the batteries.

Inspect The TV Panel

If the issue is with the TV panel buttons, you should first unplug the TV from the power source to ensure safety. Then, carefully examine the TV’s control panel for any physical obstructions or sticky substances around the volume and mute buttons.

You can use a soft cloth dampened with a small amount of isopropyl alcohol to clean the buttons and the surrounding area. Be cautious not to let any liquid drip inside the TV.

Button Manipulation

Finally, you should check if there is any button that is not functioning properly. You should try gently pressing and releasing the stuck button multiple times. It will dislodge any debris or dirt that may be causing the sticking.

If the button remains stuck, you may need to open the remote control or consult a professional technician to inspect and repair the TV’s control panel.

2. Outdated Software

Another reason why there is suddenly no sound on your Samsung TV despite not being muted is outdated software. Samsung TVs, like many other electronic devices, rely on software to function properly.

When it has outdated software, there can be anything going wrong. It can even cause different audio problems, like the Samsung TV volume being loud when turned on.

With outdated software, it may not be able to properly communicate with other components of the audio system. As a result, the TV volume can be muted.

However, manufacturers of Samsung TVs regularly release software updates. It helps the running TVs improve performance and fix bugs and other compatibility issues. So, to fix this issue, you can simply update the software.

How To Fix It:

Updating Samsung TV software is easy and it takes only a few taps on the remote control. However, follow the instructions below to update the software.

• Turn on the TV and take the remote control.
• Now, open the Setting option.
• Go below and tap on the option, Support.
• Click on the ‘Software Update’ option in the Support.
• Now, you will find an option, ‘Update Now’ if your TV has outdated software.
• So, tap on the option, ‘Update Now.’
• When the update is completed, you have to restart the TV. It will take a few seconds to turn on.

So, when the software is updated, the issue should be solved. For this kind of hassle, you can turn on the Auto Update function. It will keep your TV software always updated.

For that, you can enable the “Auto Update” feature. You will find it in the Software Update option from where you can update the software. Once you find the ‘Auto Update’ option just hit on ‘Enable.’ That’s it.

3. Issues With The Audio Cable And Connector

The frustrating problem of having no sound on your Samsung TV, even when it’s not muted, can also be the result of issues with audio cables and connectors. These seemingly minor components play a critical role in delivering audio from your TV to external devices such as soundbars or speakers.

So, when it has something wrong, it may end up completely muting the sound. The audio cables can become worn or damaged over time. Loose connections, frayed cables, or faulty connectors can be the issues as well.

These issues can disrupt the regular flow of audio signals from your TV to external audio devices. As a result, Samsung TV sound problems can appear.

How To Fix It:

First, you have to figure out whether it’s really the audio cable or something else. For that, you need to properly examine those cables. If the TV is connected to external audio devices like soundbars or speakers, check those cables too.

The cables can also have parts with wear, damage, or loose connections. In that case, you need to change them. Also, you have to ensure that all the cables are securely plugged into their respective ports.

The issue can be the result of an HDMI loose connection. In that case, you have to push them in on both ends to make sure that they are not loosely connected.

Secondly, you have to examine the TV audio setting. For that, follow the steps below:

• Take the TV remote control, and press the Home button to access the main menu.
• Select the Settings in the menu options.
• You will find the Sound option in Settings. Tap on it
• Then, select Sound Output to get the audio output settings.
• Confirm that the audio output is set to the appropriate option for your TV setup.

By default, many Samsung TVs are set to “TV Speaker.” However, if you’re using external audio devices, ensure the output corresponds to your setup.

Depending on the type of external speakers you’re using, you may have several output options to choose from.

After adjusting the audio output settings, test the sound by playing a video or audio content. Gradually increase the volume to ensure that the issue is resolved.

4. Firmware Glitch

Like the outdated software issue, firmware glitch is another problem that can cause so many malfunctions. Indeed, it can cause your Samsung TV to experience no sound, even when it’s not muted.

Firmware is the software that operates your TV’s hardware components, including its audio system. When this firmware becomes corrupted or encounters errors, it can disrupt the audio output. As a result, your TV can have the absence of sound.

How To Fix It:

If your Samsung TV software is outdated, only then firmware glitches can appear. So, the easy solution is simply to update the software. The previous section must have told you how to do that.

Once you have updated the software, make sure to reset the TV. After the restart, check if the sound problem has been resolved. Simply play a video or switch channels. If the firmware glitch was the issue, now it must be okay.

If these steps do not resolve the issue, you may need to try a factory reset. For that, simply follow the steps below:

• First, go to Settings on your TV.
• Here, go down and find the Reset option.
• Select the Reset option.
• Alternatively, you can navigate the option, Support.
• Here, find the option, Self-Diagnosis.
• Tap on this option and then, select Reset.

It will take a few minutes for the TV to turn on. This process generally erases all stored data unless you’ve backed it up. It will restore your TV to its original factory settings. At this stage, not just the audio settings, many more unnoticed problems will be solved.

5. Issues With The Audio Output Settings

Another possible reason a Samsung TV has no sound but is not muted is the problem with the audio output settings. These settings determine how audio is routed from your TV to external devices like soundbars, receivers, or even internal TV speakers. When these settings are not okay, they can lead to audio issues.

The Samsung TV sound settings can become problematic because of different factors. It can be simply a misconfiguration where the TV is sending audio to the wrong output or a disabled audio output. There can be a hardware-related issue as well.

It can also happen when the TV sends audio to an external sound system but there’s no soundbar or receiver connected. Similarly, if the internal TV speakers are disabled, it can result in the same issue.

How To Fix It:

There are indeed many different ways you might have to follow to fix the issue. It’s because finding exactly where the issue lies is a little bit difficult. However, you can try the following fixing methods in this case:

Check Audio Output Settings

If your TV’s audio setting is the issue, it can be solved if you change the setting. For that, visit the TV’s menu and then the audio settings. Check what audio output is enabled. Change it if necessary. 

If there are any external devices like soundbars or receivers connected, check their configuration too.

Ensure External Devices Are Powered On

If the TV is connected to some external speakers or sound systems, you should check it. Make sure they are powered on and functioning properly.

Verify Cable Connections

Next, you should check the audio cables. Try to recheck all the cables including the HDMI cables. There is a possibility that your Samsung TV has no sound through HDMI. All the cables should be securely connected to both the TV and the external audio devices. Change the cable if they are damaged.

Check Wireless Connections

If you’re using a wireless audio connection, ensure that it’s active. Also, you should check whether there are no issues with the wireless transmitter or receiver. If they have, change them too.

Adjust Volume Settings

Next, you should check the Samsung TV volume settings. Confirm that the volume settings on both the TV and any connected devices are appropriately adjusted. You can also disconnect them for a minute and then connect again to let them start being connected again.

Reset Audio Settings

Still, if the issue remains, you should reset the audio settings on your TV to default values. You can do this easily. For that, follow the steps below:

• First, press left on the remote from the Home screen to get and select Settings.
• Now, choose and select the All Settings options.
• Select Sound and then go to Expert Settings.
• After that, navigate to Reset Sound and finally, select Reset.

If none of the above steps resolves the issue, you should contact Samsung customer support. But there is another cause that can happen as well. Let’s learn about it for the next reason.

6. Issues With The TV’s Mainboard Components

In the worst case, the issue can be with the TV’s mainboard components. The mainboard and the motherboard are the same thing for a Samsung TV. It lets you coordinate and control various functions, including sound output.

When one or more components on the mainboard malfunction, it can severely impact the sound system. These components need to function properly for processing audio signals. They also ensure that sound is delivered correctly through the TV’s speakers.

However, if the issue is with this mainboard, I guess you can’t figure it out so easily if you are not a professional mechanic. Actually, identifying mainboard issues is challenging for the average user. That’s why you should try all other troubleshooting before you try to find out an issue with the mainboard.

How To Fix It:

As I said earlier, resolving mainboard issues is a complex task. If issues with the mainboard are confirmed as the cause of the sound problem, you should seek professional assistance. Here’s what you should do:

In this case, you can reach out to a qualified TV technician or Samsung’s customer support to diagnose and address the mainboard issues. Depending on the severity of the mainboard problem, the technician may attempt to repair the board. It might need a replacement if necessary.

Troubleshooting Samsung TV with No Sound But Not Muted

There are lots of troubleshooting tricks that can help you fix this issue at home. Even though the reasons are unknown, these troubleshoots mostly help. Let’s see what are those easy tricks that can save you time and money for taking the TV to the repair shop.

1. Check If The Content Has Sound Or Not

First of all, you should check the audio source. Sometimes, the content has no sound and you might consider it as an issue with the TV. So, for the first time when you face this issue, change the channel to see if the issue is with the TV of that content.

2. Run A Sound Test

It’s a very common test and it never removes the previous settings like a factory reset. So, you can perform a sound test anytime you want. 

Besides, if you find an issue with the test, you can reset the Samsung TV audio setting. You can do it following the solution of reason 5 that we have discussed earlier.

3. Turn Off The Sound Sensor

Sometimes, the sound sensor of your Samsung TV is on and that makes a clash with another component. As a result, your TV can stop producing sound completely.

In this case, you just have to find out the sound sensor button and disable it. You will most probably find it in the bottom or rear panel of the TV.

4. Power Cycle The TV

Power cycling is all about turning off the TV and disconnecting it from the power source to clear any temporary issues. It’s a very common troubleshooting trick that can solve numerous internal issues.

To perform a power cycle, follow the instructions below:

However, for the fourth reason, I have elaborated on the process of a factory reset. You can follow that if you want to factory reset your Samsung TV.

6. Contact Customer Support for your Samsung TV

Finally, you can call a technician to repair your TV. If your Samsung TV is still under the official warranty, make sure to contact customer support first. If a local technician attempts to fix it, the warranty policy might be violated.

However, if you don’t know how to contact Samsung Customer Service, just visit the official Samsung website. You will get the Support or Customer Service section on the right side of the top. Check this section.
