Last Updated Jun 3, 2022

Sound delays can happen for several reasons on your LG TV. Weak cable connections, skipping DVDs, or even the broadcast itself can affect the sound quality. Thankfully, many aspects of your LG TV are customizable. You can adjust your sound delays based on what you’re watching.

Continue reading to learn more about fixing your TV’s sound delays and what possible troubleshooting options you have.

How to Fix Audio Delays on webOS LG TV Models

How you fix the audio delay on your TV largely depends on what type of TV you have. If you bought your TV after 2015, it operates on webOS. If you bought your TV before 2015, it works on Netcast.

To address sound issues on a newer, webOS LG TV:

  1. Press the home icon on your remote.
  2. Select the gear icon.
  3. Choose “Sound.”
  4. Select “AV Sync Adjustment.”

Now, you can use the on-screen slider to adjust your sound settings. Sliding it one way slows down the sound while sliding it another way makes the sound faster. You might need to adjust this a few times before you find the setting that’s right for you.

How to Fix Audio Delays on Netcast LG TV Models

If you have an older Netcast LG TV model:

  1. Press the remote’s home icon.
  2. Choose “Settings.”
  3. Select “Sound.”
  4. Choose “AV Sync Adjust.”
  5. Use the sliding scale to adjust your TV’s sound.

How to Fix Audio Delays with the LG ThinQ App

If you don’t have your LG TV remote, you can download the LG ThinQ app. This transforms your smartphone into a television remote. After you download the app, simply follow the instructions listed above for webOS TVs. Make sure that your TV and the app are on the same Wi-Fi network; otherwise, it won’t work.

Troubleshooting LG TV Sound Delays

If you tried the above measures to no avail, the problem might not be your TV; it might be an issue with an external sound system. For instance, suppose you purchased an LG Soundbar, and you’re experiencing audio delays.

Try the following:

  • Reset your soundbar. You can learn more about this by consulting your product’s user manual.
  • Disconnect your soundbar. Use your TV without the soundbar. This can help you identify the source of the problem.
  • Change applications. Something might cause one of your TV’s apps to malfunction, creating audio delays. First, cycle between apps to see if it’s an across-the-board problem. If one app has sound problems and the others don’t, delete the app and reinstall it.
  • Change streaming devices. In response to a 2019 Reddit post, an LG representative said that newer LG TVs only work with the latest HDMI technology. While LG was working on a patch to address the issue, it recommended that, in the meantime, you update your streaming hardware.
  • Check your external devices’ connection. If you’re watching a movie using a DVD, Blu-Ray, or video cassette player, check your device’s connection. Try plugging in the AV component or HDMI cable into another slot. Perhaps use a new cable if you have another one on hand.

Try Connecting a Bluetooth Speaker

If you don’t already have a Bluetooth speaker connected to your LG TV, this could be the answer you’re looking for. By connecting your TV to an external sound system, you could possibly bypass any audio delays. Make sure your Bluetooth speaker isn’t connected to any other device (like your phone) before pairing it to your TV.

To connect your LG TV to a Bluetooth speaker:

  1. Put your speaker in pairing mode.
  2. Navigate to your TV’s settings.
  3. Choose “Advanced Settings.”
  4. Select “Sound Out” from the sound menu.
  5. Choose “LG Sound Sync Bluetooth.”
  6. Press “Detect.”
  7. Choose your speaker from the drop-down list.

Many Bluetooth speakers should work with your LG TV, though you may be better off connecting your device to an LG brand speaker since certain brands—like Sony—do not offer compatible speakers.

Call LG Customer Support

If you tried the above recommendations with no success, you should reach out to LG’s customer support team. After asking a few simple questions, they can provide you with troubleshooting options over the phone.

To reach out to customer support:

LG says that before reaching out to customer support, consider browsing its YouTube channel. There are tons of videos online that could provide insight into your problem.

Consider Filing a Warranty Claim

LG covers all its products under a limited warranty. If you purchased an LG TV within the last year, you could file a warranty claim where the company would assess the problem and fix it at little to no charge.

Your warranty claim’s eligibility depends on the source of the problem. For instance, LG addresses most factory-specific problems at no charge. However, if you altered your TV with “mods,” LG may not be responsible for the audio delay.

In Summary

The steps for fixing your LG TV depend on whether it’s a newer or older model. For the most part, by accessing the sliding scale buried deep in your TV’s settings, you can configure your TV’s sound quality. For more information about adjusting your LG TV, read your user manual.
