If you want to enjoy watching and listening to your favorite content on a large screen, you need a quality TV. Unfortunately, TVs aren’t perfect and can refuse to give out sound. So, if you can’t hear the sound but crave the best experience, you should fix the issue fast. You can use the tips below to do this fast at no cost.
Why Does My TV Have No Sound
To fix your TV with no sound, you need to have a rough idea of the underlying cause of the sound problem. During the troubleshooting stage, you’ll use the information to diagnose the exact issue and find the most suitable solution.
Some of the most common reasons your TV no longer produces sound are loose or damaged cables, unsuitable audio settings, and signal issues. If you’ve set the volume too low or your external or built-in TV speakers have been damaged, you’ll most likely have the same experience.
What’s more, you might have the same sound problem if your TV’s apps or operating system is outdated or software glitches are hindering your TV from operating normally. It’s also possible that your TV’s volume is not working.
Of course, hardware issues can cause hinder your TV from producing sound. Remember those hardware problems are the most difficult to fix. If you troubleshoot and discover that they are the culprits, you should consider calling a certified technician to resolve the issue.
Please also note that some TV brands are prone to this issue. For example, we have a separate guide on how to fix Vizio TV with no sound.
How to Fix a TV with No Sound But Picture (Step By Step)
Here are a few crucial steps you can rely on to fix your TV with no sound but pictures and restore its ability to give you the best quality audio:
1. Double Check Mute
Irrespective of the make or model of your TV, “Mute” can disable its sound. For that matter, you should confirm whether your TV is muted before attempting to fix the problem. If it is, press on the “Mute” icon to disable it.
2. Increase the TV’s Volume
Ensure your TV’s volume is turned up high enough to allow you to get high-quality sound. You can use your remote control.
Press the volume button to increase it. If you’re using external speakers, check the speaker’s volume as well. Increase the volume gently as you try to listen to the sound.
It would help if you did the same with your set-top box. Ensure the device’s volume is neither muted nor reduced too low.
3. Reboot the TV
Rebooting your TV is the best way to reset and fix lots of temporary software and configuration glitches. So, it’s simple but can save you a lot of time and money.
To reboot your TV, you should turn it off for approximately five seconds. For the result, press the power button on the device for a few seconds after plugging it into the power outlet. You should also turn off other devices connected to your TV to remove the errors fast.
4. Check TV Audio Input Settings
If you or anyone else presses the “AUX’ button, your TV’s audio input will change to AUX. Other actions can lead to the same result. You should change the setting to get sound from your TV since your TV won’t play through a non-connected AUX device.
5. Switch the TV Channel
You can do this to troubleshoot whether signal transmission issues from particular channels are responsible for the dilemma. If switching channels don’t fix it, the problem is likely on your end. If there are signal issues, the best you can do is wait for your station to rectify them.
6. Check Connection Cables
Ensure your connection cables are firmly connected. You can unplug all of them and plug them in again if you suspect any damage to the wires.
You may also need to try replacing them.
In addition, some connections are more complicated than others. If your TV doesn’t have an audio output for example and you wish to connect external speakers to it, you will need a switcher box or something similar if you cannot use optical.
7. Check your Headphone Port
If a headphone is connected to your TV, you won’t hear the sound from the in-built or external speakers. The same can happen if a different device is plugged into the headphone jack. The solution is to remove the headphone jack, if applicable, and ensure it remains empty.
8. Update Your TV Software Version
Ensure your TV’s software version is up-to-date. If the television is connected to the internet, you should go to the settings and choose an option that automatically allows your TV to install the updates.
Alternatively, you can update it via your USB flash drive. To do this, you should:
- Plug your USB flash drive into your internet-enabled computer.
- Go to your TV manufacturer’s website.
- Search for updated software.
- Download and save the software on your desktop.
- Transfer the file to the flash drive.
- Plug the device into your TV.
- Install the software.
9. Factory Reset the TV
When you factory reset your TV, you erase all your data and the TV settings and configurations. In other words, you restore your television to its default settings. So, if you or anyone changed the settings you don’t know anything about, this will fix the issue. It will also erase other stubborn software-related problems.
However, you may need to back up your data to minimize the risk of losing it.
The typical steps you can try to use to reset your TV are:
- Hold down your TV’s menu button for approximately 10 seconds.
- Go to “Settings.”
- Navigate to the restore factory settings.
- Follow the on-screen instructions to complete the process.
There’s no doubt the make and model of your TV determine the exact steps you should follow to factory reset it. So, you should read on if you need more on model-specific ways to factory reset your TV.
10. Seek Professional Help
If you’ve followed the above steps without success, your TV’s motherboard might have encountered a severe problem. It’s the spine of your television. Other than that, the type of repair that you require may go beyond the scope of a regular person’s skills. So, the solution is to call the manufacturer or an approved repair expert.
Note: For model-or-brand-specific troubleshooting tips, you can consult your user manual. In most cases, you’ll be able to fix the sound issue without the user manual since most TV models and brands produce sound in almost the same way. Their audio settings have also been designed with the needs of end-users like you in mind.
Let’s see how you can fix the sound issue on Toshiba TV and others without necessarily consulting the user’s manual.

If your Samsung TV has no sound, troubleshoot the problem by pressing “Menu” on your remote and selecting “Support.” Then go to the “Self Diagnosis” option and choose “Sound Test.” The TV should play a melody out of the built-in speakers.
