Sony TV Has No Sound But Not Muted

Last night, suddenly sound went out on my Sony TV; I made the following diagnosis,

It’s incredibly frustrating when you are watching your favorite show on your Sony TV, and suddenly you can’t hear a thing.

It’s a common problem, and you are not the only one facing this Audion audio issue on Sony TV.

The root cause could be anything because there are several reasons why TV shows pictures but no sound.

Quick troubleshooting options include changing TV channels, turning on/off the TV, or checking audio sources.

If the Sony TV doesn’t emit sound after these basic operations, then read this article carefully to figure out the root cause and the solution.

All the methods. Discussed below are simple yet effective to resolve the issue of sound not coming out of your Sony LCD TV.

Sony TV Has No Sound But Not Muted? – Quick Fix

If your TV shows pictures but no sound, it may be muted, the volume may be low, or an external speaker or headphones is plugged in. The quickest troubleshooting option can be to change the channel or restart the Television. Additionally, you can try to check the TV’s firmware, speakers, cable connection, or input settings.

Sony TV Has No Sound But Not Muted

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 TV

  • Extremely low or muted volume accidentally
  • Pending Reboot of Television
  • Wired or Wireless headphones are attached
  • Outdated TV software or faulting settings
  • Incorrect configuration of the sound settings
  • Improperly connected devices
  • Improperly connected cables with ports
  • Signal Source Connector Damage
  • Mainboard Elements Damaged
  • Mainboard/T-Con Short Circuit
  • SAP is turned on

Fix Sony TV Has No Sound But Not Muted

#1: Check Sound Mute

Ignore this step if your Sony TV is not mute

Did you put your TV on mute the last time you were watching the TV?

Because 1 out of 3 people press the mute button during commercial breaks, which can be a reason you only have pictures but no sound from TV.

If sound went out during the show, that’s a different scenario, but if you just turned on the TV, it gives no solution audio.

Then the potential culprit of no sound can be “Mute,” which you can unmute with the remote control.

You can unmute it automatically by increasing the TV volume. The Mute will be disabled.

So double-check the mute status of your Television.

#2: Check the Sony TV Volume Level

What if you turn on the Sony TV and the volume is set to very low, or what if the importance of the cable box is set to low or zero?

I faced this problem, and I believe others might encounter this situation when someone can forget to turn up the TV volume.

Either you did it on purpose, or due to a commercial break, or any of your kids did that, but it’s a potential reason why the sound is not coming from TV but pictures.

Grab your remote controller and adjust the volume by pressing the volume buttons, and you can quickly fix the problem of AdSense of sound from the TV in a matter of seconds.

But, if the TV volume or cable box volume isn’t set to zero, nor is it on mute, then keep reading to find out what’s restricting all sound output from the TV.

 

#3: Reboot Sony 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 Sony 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

This is a little advanced approach to fixing the Sony TV with no sound but a picture, but for a beginner, this can also be a bit technical.

You can try changing your Sony TV’s sound settings to get the audio back.

Just change Dolby Digital Plus to Dolby Digital.

  • Grab your remote and press HOME
  • Now go to the SETTINGS
  • Now select Display & Sound
  • Now choose AUDIO OUTPUT
  • Now set Dolby Digital Plus to Dolby Digital.

To connect a soundbar, speaker, or Bluetooth adapter, go to the settings and change audio settings from speakers to audio system.

For streaming devices like Cable Box, Consoles, or Roku, go to sound settings and change Dolby Digital Output to Dolby Digital Plus.

You can change sound settings from Digital Audio Out to PCM for sony Bravia TV.

TV has audio input settings for routinAudios audio to different sources like AUX, HDMI, Headphones, or external speakers.

For that, TV shows two protocols in the Audio input settings, which are

PAP ( Primary Audio Protocol ): This protocol routes audio to internal speakers

SAP ( Secondary Audio Protocol ): This protocol routes audio to AUX, HDMI, or other external sources.

If, by accident, you have enabled the SAP from the audio input settings, and there is neither AUX nor HDMI connection with the TV, then do not expect sound from the TV unless you join these sources to receive the audio input.

Therefore, you should start by checking the audio input settings because most audio issues occur when audio input settings are not set correctly.

You can change the audio input settings, but the process will differ slightly for different TV brands.

I hope that after playing with the audio input settings, you will be able to solve the TV’s audio problem, which was compromised due to the changed input.

 

#5: Examine Headphones Port

When you sense a lack of sound coming from your Television, the common sense is to check if anything is plugged into the output port because that won’t let TAudioy audio.

Suppose you have a wired or wireless headphone set in the headphones. Jack, the TV speaker, isn’t generating sound for you in this case.

You need to check the headset connected to the io of the streaming media.

Another situation you can face is whAudioe Audio streams to a different wireless headphone in your home because they can override the audio preferences.

Similar studio audio is intercepted when headphones, speakers, Bluetooth accessories, or any other audio output device is connected to the bed; that’s a different case now.

You can check if the connector is inserted correctly because if the headphone is not inserted properly in the audio-out jack, or there is debris in theAudio, audio will be compromised.

Where do I find the headphones jack?

Traditionally, the headphones jack is placed on the back side of the TV, but the location can be different for different brands and models of TV.

Additionally, if you are using your Television as a gaming monitor connected to your gaming consoles like Xbox One, PS4, or NVIDIA Shield, then you are supposed to check the ports for streaming devices, consoles, and cable boxes.

 

#6: Examine Connection Cables

If you still have no sound but pictures on your TV, there might be loose or damaged cables causing the TV to produce no sound.

Because you have to make sure that any of the connected cables are not cut, removed, disconnected or loose, or the sound could be compromised.

There is a large number of external media devices and cables that we connect with our TVs, like AUX, HDMI, SCART leads, Phono cables, Optical cables, Auxiliary cables, RCA connections, Coaxial Audio Cables, Component connections, gaming consoles, satellite receivers, Blue-ray players, or cable box.

You have to check the cable that controls audio to ensure the connection is secure; if not, you can try to unplug and reconnect firmly so that the audio signals are not disturbed.

You can do an HDMI test for Samsung TV to ensure it’s not causing the Audio problem.

You can do that from TV 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 TV volume can be changing the channel because sometimes, one channel is not working correctly, so changing the track solves the problem.

#9: Check for TV Software Updates

In some cases, update the TV software/firmware to fix the 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.

Software updates can reset the audio and video settings back to their defaults.

So, how to update the software for Sony TV?

  • Turn off automatic software updates.
  • Grab your remote and press HOME
  • Choose SETTINGS
  • Choose CUSTOMER SUPPORT
  • Scroll down to AUTOMATIC SOFTWARE DOWNLOAD
  • Turn this OFF

Some people are annoyed by the automatic updates because it just starts during the show you are watching, interrupting your viewing experience.

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.

#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 Television

You can verify MTS settings for Television when you play with the settings of the 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 TV settings

What worked for me was to reset the 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 factory reset the Sony Smart TV to handle the audio issue.

How to Factory Reset Google and Android Sony TV with Remote Control

  • Grab your remote and press MENU
  • Now choose SETTINGS from the menu
  • Now select “Storage and Reset.”
  • Now select “Factory Data Reset.”
  • Now select “Rease Everything.”
  • Now reboot your Sony TV

How to factory reset Sony Bravia TV

  • Grab your remote and press and hold the UP button
  • During this, press and release the power button on the TV ( Not on the remote )
  • The TV Screen will turn blue, and the TV will shut down
  • Turn on the TV, and it will be like a new one

Resetting can eliminate the sound and other issues your TV is experiencing, which will be fixed permanently.

Once done, check the sound; you will see the audio playing smoothly.

 

#13: Signal Source Damage

Another possible reason for a 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 TV.

 

#15: Check for hardware problems.

Finally, you can check for any hardware problems with the 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.

 

#16: Reset Audio/Sound settings on Sony TV

You can resolve the Sony TV no sound issue by resetting the sound settings.

Support you have Sony Bravia Smart TV in your home, and you need to reset the audio settings.

  • To reset Sony TV With Remote
  • Grab your remote and press MENU
  • Now from the menu, select SETTINGS
  • From there, select PREFERENCES
  • Now scroll down and choose SOUND
  • Now select RESET and hit OK

 

#17: Contact Sony TV Support

The last hope is to contact Sony’s customer support to resolve the issue. You can either call them at 1-239-245-6354 from Monday to Friday or try the live chat option for a quick response.

#18: Sony TV Warranty

If your TV is still under an active warranty, you can get a replacement or get a free repair done at your home. Usually, the Sony TV warranty is only for one year, so contact them if you think you are under contract.

 

The best part is that we have discussed and ensured these methods are for all brands like Samsung, LG, Sony, Vizio, TCL, Element, Insignia, Sharp, Hisense, Philips, Loewe, Mitsubishi, Panasonic, Toshiba, RCA, Sanyo, Emerson, Olevia, Funai, Sceptre.

These methods will work fine regardless of the type of TV, like LCD, LED, OLED, Plasma, Smart TV, 8K, 4K, QLED, 32-inch to 110-inch TV. So, start reading and implementing these methods to figure out what’s causing the TV sound not to work correctly while the picture is showing and resolve it ASAP.

Conclusion

That’s a wrap for Sony TV’s sound problem, and the common reasons for Sony TV to experience sound issues are 

  • Loose or damaged cables
  • Internal speakers damaged
  • External speakers connected
  • Outdated firmware of the TV
  • Changed sound settings of Sony TV 

So, if all these options are of no use, you better call a technician to resolve your issue.
