As a frustrated TV owner, I recently experienced an annoying sound delay when watching my favorite shows. After doing some research, I discovered there are a few common causes of this issue. In this post, I’ll be sharing the tips and tricks I used to solve the issue along with other solutions I discovered. So if you’re experiencing the same sound delay, this post is for you! We’ll be discussing the various causes of the sound delay and the solutions available to fix it.
TV sound delay can be caused by a variety of factors, including outdated software, a faulty connection between the TV and the source device, and a channel broadcast issue. Other causes include game mode activation and deactivation, as well as a full cache.
| Cause | Explanation | Solution |
|---|---|---|
| Outdated TV Software | Smart TV firmware needs to be updated to fix bugs and glitches, including sound delays. | Connect your TV to the internet, navigate to Settings > Device Preferences > About > System Software, and update to the latest version. |
| Poor Connection to Source Device | A bad connection between your TV and the source device (cable box, DVD player, etc.) can cause sound delays. | Ensure cables connecting the TV to the source device are securely plugged in. Unplug and reattach them one at a time. Replace cables if necessary. |
| Channel Broadcast Issue | Sound delays may be caused by the channel itself, not the TV. | Test other channels to see if the problem persists. If it only affects one channel, notify your cable or satellite provider and power reset your TV (by unplugging and replugging the power cable or using the TV menu). |
| Game Mode Activation/Deactivation | Game Mode should only be activated during gaming. Enabling it while watching TV can cause sound delays, and vice versa. | Navigate to Settings > Picture Adjustments > Picture Mode > Game Mode, and enable or disable it as needed. |
| Full TV Cache | A full cache on your TV can result in various issues, including sound delays. | Clear the cache by going to Settings > Applications > Manage Installed Applications, selecting each app individually, and choosing “Clear cache.” |
Cause #1: TV Software Isn’t Up to Date
Similar to your smartphone or computer, smart TVs contain firmware. This is essentially what operates your TV. It improves system performance and increases features. It also allows you to download and watch movies on various streaming applications.
If your smart TV isn’t updated to the latest version, you may miss out on several new features. Not to mention, there can be a lot of bugs and glitches. These bugs could include a distorted screen, faint colors, and, of course, audio delay.
Solution
To update your TV system software, you must first connect your TV to the internet.
Firstly, use your remote’s ‘Home’ button to navigate to ‘Settings’ and then ‘Additional Settings.’ From there, select ‘Network & Internet’ from the drop-down menu.
Next, you may select your preferred Wi-Fi network. Once connected to the internet, go back to ‘Settings’ and choose ‘Device Preferences.’ Then, select ‘About’ to locate the ‘System Software’ option.
When you choose ‘System Software,’ your TV will begin checking for a newer version available. If there’s one, it’ll display the message ‘System Update Ready’ and begin upgrading its software.
Cause #2: Poor Connection to Source Device
One of the most common reasons for TV sound delay is a bad connection between your TV and the source device. This applies to a cable box, DVD player, Blu-ray player, or any other device you may be using.
Solution
Check if the cables connecting the TV to the source device are plugged in securely and correctly. To do this, you can unplug each cable and then reattach them one at a time.
If you suspect the issue might be from the cable itself, grab yourself some new cables.
Cause #3: Channel Broadcast Issue
Sometimes sound delay might not stem from the TV but from the channel itself. So, try switching to another channel to check if the problem persists.
If you continue to experience sound delay, then the cause is most likely local. However, if the other channels are working well, then the problem is due to the broadcast of this single channel.
Solution
The first thing you should do is notify your cable or satellite provider of the problem. In the meantime, you can try power resetting your TV.
There are two ways you can do this:
Unplugging the Power Cable
- Turn the TV off.
- Remove the power cable from the wall outlet.
- Wait for 60 seconds.
- Replug the power cable into the wall outlet.
- Turn the TV on.
Using the TV Menu
- Press the ‘Home’ button on your remote control.
- Navigate to ‘Settings.’
- Select ‘About.’
- Choose ‘Restart.’
Cause #4: Game Mode Is On/Off
Most of the newer TV models include a “Game Mode” feature. This allows the TV to skip numerous video processors, reducing the amount of time the TV requires to process visual signals.
This feature is designed to reduce game lag and ensure that controller actions reach the screen as fast as possible. That said, game mode should only be activated during gaming. This is because enabling it when watching TV might create sound delays, and vice versa.
Solution
To enable or disable game mode, hit the ‘HOME’ button on your remote. Navigate to ‘Settings’ and then to ‘Picture Adjustments.’
Select ‘Picture Mode,’ and you’ll find ‘Game Mode.’ From there, you may enable or disable it as needed.
Cause #5: TV Cache Is Full
A cache is a type of memory storage on your TV. Many applications use your TV’s cache to store temporary data, which helps them operate faster.
However, the cache might fill up over time, resulting in a variety of issues, such as frozen TV memory and sound delays.
Solution
Clearing the cache on your television improves its performance and reduces lag. Here are five steps to clear it:
- Press the ‘Home’ button on your remote.
- Go to ‘Settings.’
- Choose ‘Applications.’
- Select ‘Manage Installed Applications.’
- Select each app individually and then choose “clean cache.”
Final Thoughts
TV sound delay is one of the most annoying bugs that can ruin any movie night. Luckily, you can easily fix it using these easy steps.
Sound delay is usually caused by out-of-date software, a poor connection between the TV and the source device, or a channel broadcast malfunction.
It’s also triggered by the activation and deactivation of game mode, as well as a full cache. To help you have the best movie night ever, we’ve covered all the reasons and fixes for TV sound delay!
