Sometimes, The Peacock streaming service app may not work properly on some LG Smart TVs. There can be several possible reasons for the Peacock app not functioning as expected on LG TVs. 

Here at Smart Home Apt, we shall look into different effective methods for resolving this issue.

Reasons Why Peacock is Not Working on LG Smart TV

1. Outdated LG TV Software

Outdated software on your LG Smart TV can cause compatibility problems with streaming apps like Peacock. Go to Settings > Software Update and check if there are any pending updates for your LG TV. Install the latest software update and then try accessing the Peacock app.

2. Outdated Peacock App

The Peacock app on your LG TV may also be outdated. Go to the app store on your TV and see if there are any updates available for the Peacock app. Update the Peacock app to the latest version and then open the app to check if it's working properly.

3. Internet Connection Issues

For the Peacock app to function on your LG TV, you need a reliable internet connection with adequate bandwidth. If there are any connectivity issues with your Wi-Fi or Ethernet network, it can disrupt streaming on apps like Peacock. Check your internet connection and see if there are any problems. Restart your router and modem and then try accessing the Peacock app.

4. Clear App Cache and Data

The Peacock app on your LG TV collects cache and data over time which can become corrupted and cause issues. Go to Settings > Apps > See all apps. Find the Peacock app and select 'Clear cache' and 'Clear data'. This will delete the app cache and data and refresh the app. Try launching Peacock again to see if it's working fine now.

5. Account Login Issues

If you are unable to sign in to your Peacock account on the LG TV app, you will not be able to stream any content. Make sure you are using the correct login credentials for your Peacock account. You can also sign out of the Peacock app and sign back in with your username and password. This will verify your login details and resolve any temporary issues.

6. Restricted Content

Some TV shows, movies and events on Peacock may be restricted based on your location or device. The content you are trying to access on Peacock app on your LG TV may not be available due to location or device restrictions set by Peacock. You may need to use a different device or internet connection to stream that content.

7. App Permissions

The Peacock app may require certain permissions on your LG TV to function properly. Go to Settings > Apps > Peacock app. Make sure the app has permission to access your location, storage, microphone and any other permissions. Denying certain permissions to the Peacock app can prevent it from working on your LG TV.

8. Device Limit

The Peacock service allows a limited number of concurrent streams based on your subscription plan. If that limit is reached, the Peacock app will not stream any content. Sign out of the Peacock app on other devices to end any active streams and try accessing again on your LG Smart TV. You can also verify how many concurrent streams are allowed on your Peacock subscription plan.

How to fix Peacock app not working on LG Smart TV ?

1. Ensure That Your LG TV Is Compatible With Peacock

To use the Peacock app on your LG smart TV, you must have a model from 2017 or later that runs LG's webOS. You can identify the year of your LG TV by looking at the model number, which can be found in the system menu or on a sticker on the back of the TV. For detailed instructions, please refer to this page.

If you have an LG TV from before 2017, you might want to consider purchasing a streaming stick as a more cost-effective and straightforward alternative to replacing the TV.

You can easily access Peacock on any TV, be it a smart TV or not, by connecting a Fire TV Stick or a Roku streaming stick. Both of these devices are user-friendly and offer a variety of popular streaming applications.

2. Power Cycle the LG TV

Most app issues can be resolved by simply turning the TV off and back on. This is usually due to software glitches, which are a common occurrence in software.

When you press the power button on your LG webOS TV, it won't actually reboot the device. Instead, it will go into standby mode, allowing it to start up faster. Although this may seem convenient, it can cause software issues to accumulate over time.

To force your LG TV to reboot fully:

• Unplug it from the power outlet.
• Press and hold the power button on the TV (not the remote) for at least 60 seconds.
• Then plug the TV back in.

Give the Peacock app another shot. If you're experiencing any issues, remember that restarting your device often helps solve TV bugs. Keep these instructions nearby just in case.

3. Test the Speed of Your Internet Connection

Poor internet connection can lead to buffering issues when using Peacock and other streaming services. In some cases, the connection may be too weak or unstable to even establish a connection with Peacock's servers.

To check your internet connection speed, you can run an Internet Speed Test on your computer or phone. Ensure that the device you are using is connected to the same network as your TV. For optimal results, disable your phone's mobile data and connect only to a Wi-Fi network.

If your internet connection has a speed lower than 3-4 Mbps for standard streaming and 5-8 Mbps for HD, you will need to take the below steps to improve it:

• Investigate any potential sources of interference that may be affecting your router and TV, such as too many walls between them. 
• Additionally, try restarting your router and modem to see if that helps (see the next Tip).
• Finally, contact your internet provider to determine if there are any network issues or if you need an upgrade.

4. Restart your router and modem

Many times, it is your home Wi-Fi that is causing the issue rather than your TV or the Peacock application.

Rather than spending time diagnosing and resolving each potential network issue, a simple restart of the entire system is often the most effective solution. To keep your network running optimally, restart it at least once a month.

Before you start, make sure that no one in your home is currently using the internet. This process will temporarily disconnect all internet and network connections for approximately five minutes while the device reboots.

Alright, let's get going.

• Disconnect the power cables from your router and modem.
• Allow 30 seconds to pass.
• Reconnect the power cables.
• Give a few minutes for the modem and router to restart.

Once your TV connects to the network again, try to run the Peacock app. If your network speeds were slow when you tested them, this is also a good time to run another test. Restarting your router will often boost your speeds for a short while, but it won’t fix every underlying problem.

5. Perform LG TV Firmware Update

Firmware updates can be an effective solution for resolving TV app issues, much like app updates.

LG smart TVs come with an auto-update function, however it's also possible to manually force a firmware update. Although it's not generally necessary, it is a useful feature to have in the event that the automatic update is switched off or fails without alerting you.

To proceed:

• Press the Settings button on your remote.
• Go to the General tab in All Settings. 
• Select About this TV and click Check for Updates. 
• Once the update is installed, power cycle your TV as instructed.

After updating the firmware, attempt to use the Peacock app again.

6. Reinstall Peacock App

Reinstalling the app is a simpler way to clear its data and potentially fix app-specific issues on LG TVs, rather than manually clearing the cache.

You'll have to uninstall Peacock and then install it again to complete the reinstallation.

To delete the Peacock app from your remote:

• Press the Home button.
• Select the Peacock app icon and hold it.
• Then click the trash bin icon above the app. 
• Confirm the deletion by pressing Yes in the pop-up.

To Reinstall the Peacock app on your LG TV:

• Press the Home button on the remote.
• Select the LG Content Store and then click the magnifying glass in the top right corner. 
• Type "Peacock" in the search box and select it from the results. 
• Finally, press Install to complete the installation.

Give the Peacock app another go and Input your credentials once more. Your login details won't be saved from the prior installation, so you'll need to re-enter them.

7. Agree to LG's User Agreements

In order to use all of the features and apps offered by LG, you must agree to all of the associated license agreements.

To do this:

• Press the Settings button on your remote.
• Then go to All Settings and open the General tab. 
• Once there, select About this TV.
• Then click on User Agreements. 
• Make sure to check that Accept All has been selected.

8. Check the TV Location Settings

Most streaming services and apps are limited in availability, depending on your geographical location.

Peacock and other streaming services have their own methods of verifying your location. However, they may also use your LG TV's own location setting to confirm that information.

To do this:

• Press the Settings button on your remote.
• Then navigate to the General tab under All Settings. 
• Select System and then click Location. 
• Change the zip code to your current area if it is not already correct.

9. Turn Off VPN if applicable

Most video applications and streaming services attempt to prevent access from VPNs. If Peacock has successfully blocked the VPN you are using, you may be unable to access your streaming content. To test this, the simplest solution is to disable the VPN and try the connection once more.

10. See If Peacock Works on a Different Device

If Peacock isn't working on your TV, try opening it on other devices on your network. 

If it works on those devices, it may be time to contact LG support. 

However, if Peacock isn't working on any of your devices, the issue could be related to your Peacock account or Peacock's servers.

11. Check the Status of the Peacock Server

Using Downdetector, you can check to see if other users in your area are having issues with Peacock. Generally, Peacock outages tend to be local and are usually resolved quickly.

If you have been unable to locate any information on Downdetector, it may be wise to reach out to Peacock support or view their Official Twitter Page for the most current updates.

12. Perform Factory Reset on Your TV

It's time to try a final solution: a factory reset. This will clear all of the settings from your TV, including those for your Peacock app. While this will cause you to lose all of your app data, it could be the only way to fix any streaming app issues.

To do this:

• Press the Settings button on your remote control.
• Navigate to the All Settings option under the General tab.
• Select the Reset to Initial Settings option, and confirm by clicking OK.

Attempt to run the Peacock app again. This should have resolved most software or firmware issues that may have been preventing Peacock from working on your LG TV.
