LG TV Has No Sound But Not Muted

Are you facing a sudden audio loss on your LG TV while the picture is showing?

The same happened to me while watching my favorite show on Netflix, and I couldn’t hear a thing while the screen kept working perfectly fine.

Frustrating right?

Guess what? I tried different channels but still no sound and my LG TV was not muted as well.

I tried a handful of troubleshooting options which I have discussed in detail below, and luckily, I got the sound back after trying different things.

I hope you can also fix the Audion audio issue of the LG TV by trying these simple ways to resolve the problem when the TV emits no sound but shows a picture.

LG TV Has No Sound But Not Muted – Quick Fix

If your LG TV has 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.

LG 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

  • Volume turned to Zero
  • Problem with sound settings
  • Improperly connected devices
  • Volume muted and forgot to unmute
  • A restart of the TV is pending
  • Signal source connector damage
  • External speakers or headphones are attached
  • Internal speakers are damaged and need replacement
  • Examine connection cables
  • TV Software needs to be updated

Why LG TV Has No Sound But Not Muted

#1: Check Sound Mute

Ignore this step if you are sure about the mute status.

Before digging deep into why you are not getting sound with media, try to check if your LG 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 LG TV Volume Level

As soon as you turn on the LG 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 LG TV

The next possible solution to fix the LG 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

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

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

You can try changing the sound settings on LG TV like you can start with turning off the Smart Sound mode.

Grab your remote and press Home/Start and choosing settings and then sound.

Similarly, you should also change sound out settings if you connect external devices like Speakers, Sound-bar, DVD players, then the output sound should be adjusted.

So try Audio Out, followed by LG Sound Sync and finally, Internal TV speaker + Audio Out.

For those having DOLBY sound can try to turn off the Dolby Atoms from the sound settings.

Once done, go to Sound Out and make sure Optical > Sound Out is set to PCM.

 

For other TV brands there are 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.

 

#5: Examine the Headphones Port of LG TV

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

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: Check cables

If you still have no sound but pictures on your LG 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 LG 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: Update LG WebOS Software

In some cases, update the TV software/firmware to fix the TV with no sound but a picture.

Sometimes there can be a glitch in the software that can make LG stop to stop giving sound. Simply updating to the latest version of the firmware can handle the sound issue.

To update LG TV software automatically, you can

  • Grab the remote and Press the Home/Start
  • Now choose Settings
  • Now enter All Settings
  • Choose General
  • Go down to About this TV
  • Check for automatic updates if unchecked

Automatic updates can be annoying sometimes when the TV starts to update while interrupting your viewing experience.

Manual Firmware Update of LG TV

  • To manually update the firmware of your LG TV, you can visit the official product pa.ge
  • Enter your model number to see the latest version updates
  • Download the file and save ittoo your flash drive
  • Keep the USconnectionedtoh your laptop/PC and unzip the file
  • Create a folder with name “LG_DTV” and place a file called EPK in that folder you made
  • Now insert USB in the LG TV and follow the on-screen instructions

Once done, the firmware should be installed,d and the latest version of the firmware should erase all the sound issues from your LG TV.

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.

#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 follow the on-screen instructions to reset the TV for factory settings.

To factory reset, you can go to the

Settings of the TV > Click on Reset Factory Settings

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.

 

Contact LG TV Support

The last option you have to save some bucks on a new TV Just because your old LG TV is not giving you sound is to contact the suppor. Maybee, they can help you.

LG TV support team can be reached at 1-833-378-0003

Monday – Sunday, 8:00 AM – 9:00 PM EST

Luckily, they also have text messages and live chat options for quick chatting.

Check LG TV Warranty

If your LG TV is still under an active warranty, you can get a new replacement for the TV or at least get your older LG TV repaired for the sound issue.

If the warranty covers your TV, you could be able to get in-home service as well.

 

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

In a nutshell, your LG TV may not be facing a real sound issue,e but it could be something simple like loose or damaged cables, sound set to zero or mute, or connected wired or wireless headphones. So, you canindeedy resolve the issue by either resetting the LG TV, upgrading the TV’s firmware, or getting a replacement for your warranty if nothing helps.
