Many owners of LG brand TVs are faced with a lack of sound. If old models rarely had such a problem, then new devices with the Smart TV function have this phenomenon quite often. It can occur due to a banal system freeze, or due to a serious breakdown. Let’s consider for what reasons the sound disappears, and how to fix the problem yourself.
No sound on LG TV – how to fix it?
If the TV lost sound, then the first thing to do is to restart the device. To do this, unplug the cord from the outlet and wait 60 seconds. After a minute, you should turn on the device again and make sure that there is sound. As a rule, this method helps to solve the problem in 70% of cases.
When disconnecting the TV from power, it is extremely important to wait at least 1 minute. While the device is off, try holding the power button for 30 seconds. The key is located on the body, not on the remote. Be careful.
In the off state, the TV performs a soft reset. This process is different from the usual plugging/unplugging the device from the power outlet.
Eliminate commonplace reasons
If the TV lost sound, this does not mean at all that the problem is in incorrect settings or system errors. First of all, you need to check if the Mute function is active. Sometimes users press this button by accident and then cannot find the reason for the lack of sound. To disable the option, you need to add sound using the appropriate keys. If this does not help to solve the problem, then we proceed to check the operability of the remote control. Perhaps his batteries are dead or he is completely out of order.
If the remote works properly and the Mute function is disabled, then check if the TV has other connections. For example, headphones. Perhaps the sound is coming to them and you can’t hear it.
Another common cause of no sound is problems with the cable supplier. If the operator carries out maintenance work, then some channels stop broadcasting normally. To test this theory, just switch to another TV channel or launch the application (relevant for Smart TV).
Update the software on your LG TV
Outdated software often causes problems in the system, including causing the sound to cut out abruptly. To prevent this situation, try to update the TV as soon as a new firmware is released. Sometimes this happens automatically, especially if the user gives permission to download programs from the Internet. In other cases, confirmation from the owner is required.
To check for a fresh update, use the instructions:
- Press the Home button on the remote.
- Enter the “Settings” section, and then the “General” category.
- Select the “About TV” section.
- Check for updates, and also check the box next to the “Auto-update” function.
If the Internet connection is weak, the update procedure may be interrupted. That is why the old firmware remains on the TV, which continues to malfunction. To reinstall the software, you will need to carry out the procedure manually.
To do this, you need to follow a simple algorithm:
- Go to the Product Support page.
- On the main page of the site, enter the number and model of the TV.
- Download the file and extract the archive data.
- Send the files to a flash drive, giving them the name “LD_DTV”.
- Insert the flash drive into the TV and install the programs.
After installation, try to turn on any channel again and check for sound. Most likely, it will appear immediately.
Along with the settings, check the connectors and connectors. They allow users to connect set-top boxes, computers, projectors and other devices to the TV. If the same connector is used frequently and for a long time, then wear occurs. Over time, it loosens and ceases to securely hold contacts. Check the integrity of the connectors and replace them if they are out of order.
Reset to factory settings
Resetting the settings to factory settings often helps to solve the problem with no sound. This happens when errors appear in the operating system. After a reset, all functions return to their original state, and accidental errors disappear.
Work on rebooting the system is carried out through the “Settings”. The appearance of the interface depends on the brand and year of manufacture of the TV. As a rule, “Reset” is located in the “General settings” section.
Check the speakers for proper operation
If the sound on the LG TV has disappeared, you should not involve the masters or call technical support. It is enough to check the banal reasons and, excluding them, check the speakers for performance.
First of all, you need to turn off the external audio outputs and free up all the ports available on the TV so that the sound is not redirected to the speakers or speakers. After that, turn on the TV and turn up the volume using the remote control. It is important to turn on any TV channel or video.
If there is sound during playback, but it is fuzzy, has an echo or loud musical accompaniment compared to the speech of the characters, then the problem is hidden in the wrong settings. To reset, go to the “Menu” section, enter “Settings”, find the “Sound” item, and carry out the “Reset”.
After going to the “Sound” section, you need to check the sound quality of the speakers. In the appropriate section, set the value to “TV Speakers” or “Speakers”. If this is not done, then the TV will redirect the sound to the speakers, and you will not hear it.
In rare cases, users are not to blame for the lack of sound. This problem occurs when starting analog data transmission. Check if your device supports the broadcast of the installed format.
