This is a common issue that occurs with Samsung, Sony, LG, Vizio, Philips, Sharp, Panasonic, and other brands where sounds go off on one or multiple channels but pictures keep showing with no sound.
Before considering replacing the TV with sound but no picture, try to figure out what is causing the TV to produce no sound but only picture. Because, primarily, a simple troubleshooting method can bring back the thAudiot audio of the TV.
Potential Reasons for No Sound on Vizio TV

Fix Vizio TV With No Sound But Not Muted
#1: Check the Sound Mute of Vizio TV
You can skip this if you are sure that your TV is not on mute.
Before digging deep into why you are not getting sound with media, try to check if your Vizio TV is not set on mute.
Research shows that most people put the TV on Mute during commercial breaks, so it could be you behind the sound not coming from the TV but a picture.
So, double-check the mute status and if TV is on silent, grab the remote control and unmute by pressing the “Mute” button.
You can also unmute the TV by increasing the volume through the remote controller, and the Mute function will be disabled automatically.
#2: Check the Vizio TV Volume Level
As soon as you turn on the Vizio TV and TV gives you no sound but pictures.
Try to increase the volume from the remote controller, and you will find that either the TV volume or Cable box volume was set to low or zero by you or maybe by your kids.
This simple fix can get TV sound back in a matter of seconds without getting panicked.
What if the TV volume is not low and it’s not even set to mute, but still, the sound is absent from the TV? Then you need to try other troubleshooting methods listed below.
But double-check the sound status on the screen first, and if everything seems fine, find out what’s restricting sound output from the TV.
#3: Reboot Vizio TV
The next possible solution to fix the TV with the picture but no sound is to reboot the TV and all the connected devices with the TV.
Restarting seems simple, but he wonders if it’s the underlying issue of no sound from the TV with the picture.
How to Reboot TV?
- Step1: Disconnect the TV from the AC power
- Step2: Unplug the TV from the wall
- Step3: Press and hold the power button
- Step4: Wait for at least 30 seconds
- Step5: Plug it back and press the power
- Step6: Connect the devices with the TV and turn them on as well
Once done, play anything on YouTube or Netflix and check if you hear the sound.
Rebooting the TV refreshes the settings, and all the glitches or issues get resolved during this process, and that’s why you will mostly restore the TV audio after this process.
#4: Customize Audio Settings of Vizio TV
If rebooting doesn’t improve audio, try this little advanced technique to bring audio to your Vizio TV.
All you have to do is check the audio input settings.
Just to let you know, the audio input sends audio signals to the TV.
So, one of the reasons when TV gives no sound but pictures is when audio input settings are not set correctly.
You have to check if the SAP ( Secondary Audio Protocol ) isn’t enabled from the TV audio settings.
If SAP is enabled, that meaAudioe audio is routed towards the AUX or HDMI ports, and if they are connected with the TV, you wonAudiot audio from TV speakers.
So, from the TV’s on-screen menu, you need to check if the audio input goes to the internal speakers, not external speakers or any other input source.
You may have pressed it accidentally, but with compromised input settiAudiof audio, you won’t listen to a thing from the TV.
You can change the SAP to PAP ( Primary Audio Protocol ).
Depending on the TV brand, the process will slightly differ, but a significant part of this process is identical for all types of TV.
For TCL and Roku TV, try this method.
Remote > Home > Settings > Audio > Audio ( Stereo )
For Samsung TV
Support > Self Diagnosis > Start Sound Test
If there is an issue, reset the sound settings
Settings > Sound > Expert Settings > Reset Sound
#5: Examine Headphones Port on Vizio TV
Another big reason for no sound coming from your Vizio TV is when something external ( Headphones or speakers ) is connected to the TV, and due to that TV won’t play audio in the internal speakers.
When wired or wireless headphones/speakers are connected with TAudioe, audio is routed to these connected devices or devices like Bluetoothaccessoriess or any other audio output devicAudion audio will be transmitted into these devices in the internal speakers.
If, due to back luck, you cannot hear sound in the headset or speaker plugged into the headphones jack, then make sure the connector is inserted correctly or clear the jack from any debris which can cause problems.
If the TV intercepts audio, check for any other wireless headphones in your home because they can override the audio preferences. So the sound of streaming media will be playing in any other headphones altogether.
Where do I find the headphones jack?
The headphone jack is mainly installed on the rear side of the TV for most brands and models, but for some, the location can be different, and you may have to find that yourself depending on the brand and model you have.
Another scenario can be when you are using your TV as a monitor for playing games where you have connected your gaming devices like your PC, console, PS4, or NVIDIA Shield,f you face probation audio; you can check whether the streaming devices are correctly connected.
#6: Examine Connection Cables
It could be that the HDMI cable is not connected properly or damaged and that’s why it’s causing disruption with audio.
You can start checking with the HDMI connectivity to see if you can retrieve audio of your Vizio TV.
HDMI cable can be loose, damaged, cut, so you should better start checking it on both ends or better swap the ends of the HDMI cable and insert again properly and firmly. Another option can be to change the HDMI cable with a new cable and then head towards checking the HDMI port.
HDMI port can also be a culprit of improper audio from your Vizio TV so check if there is anything stuck in the port or debris in the port. Sometimes, the port is damaged when too much pressure is applied while inserting cable so the port could also be non-functional in some cases.
By the way, you can also test the HDMI port within the TV.
damaged cables can be replaced; when the TV seems to produce no sound, check if cables are secured, not any cable is cut, removed, disconnected, or loose,
Double check the connection cables when TV is giving no sound but pictures because when the external media devices or hardware devices like gaming consoles, satellite receivers, Blu-Ray players, and cable TV boxes are not connected properly, the TV struggle with audio.
Similarly, when you connect different cables with the TV, like HDMI cables, SCART leads, Phono cables, Optical cables, Auxiliary cables, RCA connections, Coaxial Audio cables, or any specific cable or component that controls audio, you should check the physical connection.
If not, check that the wire isn’t disconnected, cut, damaged, or loose because these are the potential reasons why the TV doesn’t produce sound.
The simple option can be to unplug everything, plug them back, and reconnect firmly to avoid any more issues.
You can try the HDMI test for Samsung TVs by going into the HDMI settings.
- Go to TV settings
- Scroll to Support
- Find Self Diagnosis
- Find Signal Information
- Click on HDMI Cable Test
- Click on Start Test
By doing so, you will make sure that HDMI isn’t causing the audio problem with the TV. Any problem there is will be taken care of by the built-in TV program.
#7: Check Internal and External Speakers
the issue with your TV speakers, internal speakers, external speakers,
Until now, if nothing has worked for you to fix the TV audio, It could be possible that the internal speakers are damaged or there is some issue.
It could be a reason if you have been using the TV at total volume or using an amplifier that is more potent than speakers and can push the TV’s internal speakers to limits.
Similarly, due to any reason, the IC of the speaker could have been damaged.
By the way, IC drives the internal speaker and can heat up and fail. So, you may have to replace either the IC or the mainboard/motherboard of the TV, which is beyond an ordinary person’s skills. So, it’s better to get the help of a technician for that.
The motherboard part number is 1AA4B10N260A0, and the number of the IC is LV4906, in case you purchase them.
Now, if you have been using external speakers with your TV, you should also check if those speakers are working fine or not. Otherwise, you will keep saying that the TV has some issues, which is why the TV gives no sound but pictures.
For sony TV, you can follow the process below when using an external soundboard or A receiver audio system.
- Set “Control for HDMI” for both audio systems to “On.”
- Turn on Audio Return Channel on Soundbar
- Set the audio output destination from the TV to “Audio System.”
- Press Input or TV from remote
- Turn on the TV, Turn on the Audio system
- Set TV’s digital audio output setting to PCM
For LG TV
- Go to the scenes on the TV
- Find All settings
- Locate to sound
- Click on Sound Out
- Choose HDMI ARC, Optical, or Bluetooth
For Samsung TV
Settings > Sound > Sound Out > Sound Expert > HDMI ARC, Optical, Bluetooth,
#8: Change Channel
The quickest fix for the Vizio TV volume can be changing the channel because sometimes, one channel is not working correctly, so changing the track solves the problem.
#9: Update Vizio TV Firmware
In some cases, update the TV software/firmware to fix the Vizio TV with no sound but a picture.
Updating the TV’s old or outdated OS/firmware from the previous version to the latest version can remove all the issues and glitches within the TV. Hopefully, the sound issue will also get resolved after this.
The firmware update procedure can be different for different TV manufacturers.
Either you can connect the TV to the internet to download the latest firmware version or install the software on your laptop/PC, copy it into the flash, and insert the moment into the TV’s USB port to install it.
After upgrading the TV software, the TV should play snow if that was why the TV was not producing sound.
To update the firmware of Vizio TV follow this method:
- Grab the remote and press V
- Choose System from the on-screen menu
- Select Check for Updates
- See if there is an update available to install
- Select the update and confirm the installation and restart TV
Once the TV restarts, chances are the TV will no longer face the audio issue.
#10: Perform an Analog Broadcast
Another quick fix for a TV is not giving sound but the picture to perform an analog broadcast.
When you use a TV with an analog broadcast, you will listen to the noise while turning, which means the TV is working fine. If no sound comes, that means the TV has an issue.
#11: Verify MTS settings for Vizio TV
You can verify MTS settings for Television when you play with the settings of the Visio TV Stereo.
When you see that the TV is giving the lowest sound if only one speaker is working, that means TV is not set to stereo. And it’s not able to transmit signals from stereo settings.
You can replace or adjust the source device.
#12: Reset the Vizio TV settings
What worked for me was to reset the Vizio TV to its factory settings.
I must tell you that resetting the TV does remove all incompatibility issues, glitches, or faults in the TV.
But a factory reset will erase all the data, preferences, information, and configurations you had done previously.
After the reset, the TV will act like a brand-new device with new audio settings that will eliminate the audio loss issue.
When you reset the TV, it clears the short-term memory of the TV and resolves all other issues, which is why the sound is restored after this process.
You can follow the on-screen instructions to reset the Vizio TV for factory settings.
Let’s see how to factory Reset Vizio TV with a Remote:
- Grab the Remote
- Press System on remote
- Choose Reset & Admin
- Select Reset TV to factory defaults
- Enter passcode, Four zeros ( 0000 )
Let’s see how to factory Reset Vizio TV without a Remote:
- Press and hold power button on TV for few seconds
- TV will ask you to press and hold the input button
- Press it and keep it pressed for few seconds
- TV will turn off and restart automatically
- After TV restarts, the sound issue will be resolved
#13: Signal Source Damage of Vizio TV
Another possible reason for Vizio TV with no sound but pictures can be the damaged signal source.
The source of the TV signal should be more than 20dB.
Luckily, Samsung TV allows you to do that yourself by
Going into the settings > Support > Self-diagnosis > Signal information.
#14: Mainboard Elements Damage
The mainboard, also called the motherboard the rich, is the backbone or the spine of the TV set; if it turns into an error or problem, the TV will surely lose the ability to produce sound with a handful of other issues.
The bad news is that you cannot do anything here because playing with a TV’s technical parts is beyond a regular person’s skills unless you are a TV technician.
Recovering the mainboard can help you restore the sound of the Vizio TV.
#15: Check for hardware problems of Vizio TV
Finally, you can check for any hardware problems with the Vizio TV, like if the signal source is damaged, internal or external speakers are damaged, or the mainboard is damaged. In this case, all you can do is get help from a professional TV expert.
