LG TV No Sound

While LG has been one of the leading producers of top-quality TVs in the past years, even their products can sometimes suffer from trivial issues like having no sound output. This issue has been highlighted by a number of users, claiming that the TV’s display is working fine, however, there isn’t any sound coming out. So, how can you fix that?

Your LG TV’s sound output may malfunction if the system has outdated software, loose HDMI cables, LG’s Smart Sound is enabled or maybe there’s a glitch in the TV application you’re trying to run. To solve these issues, you can try plugging in new HDMI cables, updating your TV’s software, or just disabling the Smart Sound setting.

While all these fixes may seem simple at first glance, the multiplicity of options confuses most people. Fortunately, we’ve compiled a detailed explanation of all the reasons that cause your LG TV’s sound to malfunction, along with step-by-step fixes to solve the problem.

Reasons For Your LG TV Not Having Sound

Before we head on to fix the issue at hand, you need to understand and identify what may be causing the issue, so you can jump to the right solution. Here are a few common causes that result in your LG TV’s sound output malfunctioning:

Reason 1: Sound Settings

If you are not getting any sound on your LG TV, the first thing you should check is the actual sound settings of your TV. People often change the sound settings by mistake, which leads to the TV giving no sound output on some devices and applications, even if the display keeps running.

The most common root of the issue lies with the Smart Sound setting in LG TVs. While this setting automatically filters out sound, it can often result in eliminating the volume altogether.

Reason 2: Damaged Cable

Whether you are using an HDMI cable or an optical audio cable, you need to check that they have been plugged into the TV properly if you want to hear high-quality sound from your TV. Furthermore, you need to ensure that the cables you are using have not been damaged in any way. You can also try swapping your cables with new ones to make sure that they aren’t faulty.

Reason 3: Damaged HDMI Port

Another plausible reason for the lack of a sound output can be a damaged HDMI port in your LG TV. The simplest way to diagnose this issue is to plug the same HDMI cable into a different HDMI port. If the no-sound conundrum is fixed, you’ll have your answer and will probably need to get the original HDMI port repaired.

Reason 4: Outdated Software

If your LG TV is running on an older firmware, you can often face the no-sound issue. Plus, newer devices connected to your TV may not be compatible with its outdated firmware, resulting in the TV’s sound malfunctioning. Updating to the latest software on your LG TV will give you a higher level of compatibility with newer devices and can get rid of any bugs or issues you may be facing.

Reason 5: Application Glitch

Sometimes, the application you’re trying to run on your LG TV may be facing some glitches and errors that can affect the complete system. Such glitches can often end up in disabling the sound system and can be fixed by either uninstalling the application, restarting your TV, or waiting for the application to get an update that’ll fix the current bugs.

Fixes To Solve The No-Sound Issue

Once you’ve understood the leading cause of the problem, you can start attempting the fixes listed below to get your sound back running. Let’s get to them:

Solution 1: Perform A Soft Reset

Restarting your TV to fix the issue might seem too clichéd but it can be extremely effective. A simple soft reset allows all applications on your TV to restart from scratch, taking care of any glitches or errors that might be preventing your TV from outputting any sound. Here’s how you can do that:

Step 1: Unplug your TV from the wall and keep it unplugged for the duration of the soft reset.

Step 2: Press the power button on your TV for about 30 seconds to allow any residual power left to leave the system.

Be sure not to press the power button on your remote, as this will have no effect on an unplugged TV.

Step 3: Wait for about five to ten minutes before turning your TV back on and look to see if the issue has been fixed.

Solution 2: Disable Smart Sound

The Smart Sound function in your LG TV allows the system to remove any extra sound, which can often lead to it completely preventing any sound from coming through the speakers. While the setting may be a good option when streaming at a high volume level, it is best to keep it disabled if you’re comfortable listening at a normal level.

To disable the setting, follow these steps:

Step 1: Click on the Home button on your remote and select the gear icon to open up Settings.

Step 2: Press the Sound tab and head over to the Smart Sound option.

Step 3: Turn off the Smart Sound setting and restart your TV to check if the issue has been fixed.

If there still isn’t any sound coming from the TV, head over to the next fix.

Solution 3: Check Sound Output Settings

If you’ve connected your TV with an external speaker, it could have a conflict with the TV’s internal speaker system, which can cause the TV to not produce any sound from either of the speakers. If your TV’s primary speaker is turned off, it can also result in a lack of sound output.

To fix this issue, you need to check if the sound output is set to the right speaker. Do this by heading over to the LG TV’s Sound Settings and switching between different audio output options, i.e the internal TV speaker or the HDMI cord. The audio outputs that don’t produce any sound, even when selected, need to be reconnected properly or replaced/repaired.

Alternatively, if no audio output option produces any sound, then you can proceed with other solutions.

Solution 4: Update TV Software

As mentioned before, outdated firmware is a major reason your new device is not configured with your LG TV. To ensure that you have the latest software installed to allow your TV to cater to all the connected devices, here are the steps you’ll need to follow:

Step 1: Press the Home button on your remote and select the Settings icon.

Step 2: Click on All Settings → General → About this TV.

Step 3: Press the Check for updates option to see if your software is up to date. If not, you will be prompted to install the latest software. Follow the prompts and wait for the TV to turn on with the new software to check if that has fixed the issue.

For the future, you can also enable the “Automatic Updated” option over here to make sure that you don’t have to manually download and install the software the next time there’s an update.

Solution 5: Perform A Factory Reset

If nothing else has worked, resetting your TV to the default settings might be the only way to fix the issue. However, bear in mind that this will remove all downloaded applications and files available on your TV, so it’s recommended to back up your files on an external hard drive before proceeding. Once that’s done, here’s what you need to do:

Step 1: Press the Home button on your TV remote and select the Settings option.

Step 2: Navigate your way to Advanced Settings → General Settings → Reset to Initial Settings.

Step 3: Reset your TV to factory settings and restart it once the process is completed. Hopefully, you’ll be able to hear a sound output now!
