LG TV Volume Adjusts Itself, Won’t Work, Goes Up or Down

Imagine watching a movie on your LG TV, only to be interrupted when the volume suddenly dies off or becomes very loud. It happens to many LG television owners, but before you schedule a repair, you should try to troubleshoot the problem at home first.

If your LG TV volume adjusts itself or won’t work, try cleaning the remote with isopropyl alcohol, perform a factory reset to override any changes, and update the firmware in the Support menu. The internal TV speakers, app, or external speakers can also cause volume issues.

There are easy fixes for most audio problems you may encounter with your LG TV. Read on to discover how you can fix these issues.

LG TV Remote Won’t Control Volume

There are occasions when your LG TV remote acts up, and you cannot adjust the volume when you press the correct keys.

LG TV Volume Will Not Go Down or Up

If the remote is acting up, the first thing that you should check is whether the batteries still have enough juice for the remote control to work. You can stock up on batteries such as these 24-piece packs of Energizer AA batteries.

If the remote still doesn’t work properly, even after installing fresh batteries, the volume keys might be stuck. To correct this, you can try the following:

  • Take out the batteries.
  • Press and hold the power button for one minute.
  • Press on all the buttons, especially on the volume up or down button.

Opening and Cleaning the Remote Control

If your LG TV volume keeps turning down or if your LG TV volume turns up by itself, and you’re sure that there are no stuck buttons on the remote control, then you may need to open the remote control and clean it. You’ll need to pry it open using a thin plastic card or a small screwdriver.

Once you have the remote control opened, you can clean the board with 70% isopropyl alcohol. You can choose something like Chem Corp. 70% IPA or this MaxTite Isopropyl Alcohol.

Replace Your Remote Control

If these steps fail, you may need to send the remote back for repairs, or just buy something like the LG AN-MR19BA Smart TV Magic Remote Control, which works with several models, including:

  • W9
  • E9
  • C9
  • B9
  • SM99
  • SM95
  • SM90
  • SM86
  • SM81
  • UM80
  • UM75
  • UM73
  • UM71
  • UM6970 Series

Or you can upgrade to a smart remote control like the Logitech Harmony Companion. Smart remote controls allow you to use Alexa or your smartphone to control the TV, aside from the unit itself. You can even control other devices such as gaming consoles, Blu-Ray players, Apple TV, satellite boxes, etc.

LG TV Sound Distorted

If your LG TV has distorted sound, chances are it’s because of a faulty audio circuit. This defective circuit might be in your TV or the external speakers connecting to it.

If you’re using a home theater system or an external speaker, be sure to toggle the Internal TV Speaker option to Off. How do you do this?

  1. Using the remote control, press the Settings menu, represented by a gear icon. Then go to Settings and then Sound.
  2. From the Sound menu, choose Sound Out, press ENTER, or push on the WHEEL.
  3. You can choose your device for the single sound out, internal speakers, optical, HDMI ARC, or Bluetooth. Choose the option that matches your set-up.
  4. You can also choose to have two sound-out devices. This setup is when you have an external speaker that you want to pair with the internal speakers.

Conducting a Sound Test

How do you know if it’s a signal problem or if there’s some issue with your LG TV? You’ll need to conduct a sound test to see if the problem is with your TV’s internal speakers. To do this, first, go to the Setting menu and choose All Settings.

Then go to the Support tab and then choose Additional Settings. Choose Sound Test. This sound test will behave differently depending on your setup. For instance, if you’re using an external speaker, the sound test will turn it off and instead use the internal speakers.

As such, the sound test will help isolate the problem. When doing the sound test, if your audio isn’t distorted, then it means that it’s not a problem with your LG TV. You might need to check the speakers or the home theater system you’re using for your TV’s audio.

If you’ve checked your external sound systems and you still have problems with distorted audio, you can try to update your LG TV to the latest software and firmware versions.

To do this, go back to Settings and then go into the Support menu. Look for Check for Updates and wait for the process to finish.

Not the TV, but the Distortion Remains

If you’re using a single over the air channel or a single device and the sound is still distorted, this rules out the TV. If you still hear the distortion on all channels, then you should:

  1. Open the SOUND menu again by following the steps above.
  2. Select Sound Mode Settings from the sound menu and see if the distortion is gone.
  3. Press the Settings button Icon on the remote control and select Settings > SOUND> Sound Out, then press WHEEL or ENTER.

If these steps fail, it’s time to schedule your LG TV for repair.

LG TV Volume Goes Up and Down / Keeps Turning Down / Turns Up by Itself

If your LG TV volume automatically goes up or down and it’s not the remote control that’s causing the issue, then you might need to do a factory reset.

Sometimes, having your TV’s volume automatically adjust itself might be because you’ve configured something wrong. LG TVs have a factory reset that allows you to use the default settings configured by the manufacturer. A factory reset will override any changes you made to your TV.

So if you configured something wrong, then a factory reset will be an excellent way to undo these settings. To do this:

  1. Switch your LG TV on, and then tap on the Home button on your remote.
  2. Open the TV menu and choose Settings.
  3. Look for the General options and choose Reset to initial settings.

Once you’ve done this, your LG TV will display a message for you to confirm reset. Enter the reset password, and your TV’s configurations will revert to their defaults.

Note, however, that doing a factory reset on your LG TV will result in all your apps and application data being wiped out.
