Some Basic Checks
Here are a few checks that can help you solve the problem and get back your TV sound.
Double Check Mute
Mute can fully disable the sound on your TV. So, it is very important to double-check this setting.
Sometimes, anyone other than you can mute the sound and you may not know about it.
Even if you have checked it earlier, we recommend checking it now to proceed further.
Turn Up Volume
If the volume is turned to zero or a very low level you will not get any sound coming from the TV.
Check your TV speakers’ volume and if you are using External TV Speakers, make sure to check their volume is high.
Moreover, check the volume of the connected device. Many media devices take control of your TV and its volume. If the volume is zero on them, no sound will come from your TV.
Switch The TV Channel
Sometimes there occurs a transmission problem and you fail to get sound from a particular channel.
The problem is not on your end. You should change different channels and see if you get the sound.
The problem could be on your end if you don’t hear sound at any channel.
Check Headphone Port
A headphone may be connected to your TV that is away from your eyes. Mostly the headphone jack is in front of your TV.
So check if the headphone jack is empty and nothing is plugged in there.
Examine Connection Cables
Sometimes plugging or unplugging can leave the connecting cables slightly loose or disconnected.
It is also possible that you moved the TV which loosens the cables. This can result in no sound and you will just see the picture.
It is better to plug all the connecting cables again to make sure they are connected properly.
If you see any damage to a cable, try changing that cable as it may have been damaged.
Moreover, clean the connection ports to remove any debris. Accumulated lint is one of the common causes for loose connections.
Check External Speakers
To check if the TV is delivering the sound, you should connect an external audio device like a receiver, surround sound, or any other device to play audio.
Test if you can hear the audio from external speakers. Connect them with some other device to check their performance.
Check TV Settings
Some wrong settings can also cause no sound issue on your TV. You have to check the following settings;
Disable Secondary Audio Protocol
You will not get any sound from your TV speakers if your TV is set to Secondary Audio Protocol (SAP).
This feature functions to play a program in a language different than the language in which it was recorded. So, you can watch an international program in your local language.
However, this feature is available on antennae, set-top boxes, DVR, satellite receivers, or other media devices.You can turn SAP by the following method;
- Check your TV remote control to find the ‘SAP’, ‘MTS’ or ‘AUDIO’ button. Press any of these buttons to turn OFF/ON the SAP feature.
- If your TV remote does not have these buttons then you can disable SAP from the settings.
- Press the ‘Menu’ button on the remote control and choose ‘Settings’.
- Click on ‘Audio’ settings, find the ‘SAP’ option, and disable it.

TV Audio Input Settings
Sometimes audio input is changed accidentally by you or anyone else having remote of your TV and you are unaware of it.
For example if anyone with the remote of TV presses “AUX” button, the audio input will be set to AUX but there will be no such device connected.
In this case the audio will be playing through the device that is not actually connected to the TV.
So double-check that you are using the right input option.
Troubleshooting the TV with no Sound
Now, we will apply some quick and effective troubleshooting tricks to fix the sound issue.
Reboot The TV
All the gears need to be rebooted overtime to keep running properly. For every electrical equipment, a reboot always works as a little reset and solves a lot of problems.
You should also try turning off your TV and other devices connected to it. If there is any temporary problem, it could be solved just by a reboot.
Reset The TV
Change in settings can cause a lot of problems. Especially, when you change the settings you don’t know about them, they disturb the functionality of the device.
As with TV we often change things even if we don’t have complete information about them. To get factory settings of your TV, the best solution is to restore the TV to its default settings.
This could erase all your data but it is the only step to make sure that all the settings are fine.
This sometimes solves the problem. If the problem persists, we will be sure at least that settings are ok and will be able to proceed further to next steps.

You should check which version of software your TV is currently using. TV manual can help you a lot in this case.
Check if there are updates available to the software. If an update is available you need to update it at the earliest.
TV software can be automatically updated if connected to the internet. You can also update it manually VIA USB drive.
Inspect the Hardware
If nothing works, the hardware of your TV may be faulty. It can be a small defective component or a larger part that has failed.
Damaged Built-in TV Speakers

There are a few chances that any circuit in the TV is damaged.

You can perform a signal check by going into the settings of your TV. Open support, self-diagnosis, and signal information.
