Adding apps to your LG Smart TV opens up a whole world of entertainment and content options. From streaming the latest shows on Netflix and Hulu to listening to music on Pandora and many more, apps make your LG TV even smarter. 

The LG Content Store has a wide selection of free and paid apps to choose from.

Here are 10 potential fixes for issues you may encounter when adding apps to your LG Smart TV:

1. Restart your LG Smart TV:

• Using your LG TV remote, navigate to the "Settings" menu. Select "General", then choose "Power" or "Reset".
• Choose the "Restart TV" or "Reboot" option. Your LG TV will shut off and restart, which typically takes 1 to 2 minutes.
• Once restarted, try installing your app again. The restart should have refreshed the software and cleared any minor glitches.

2. Check for software updates:

• Go to the "Settings" menu, select "General", then choose "About This TV". Select "Check for Updates" or "System Update".
• If an update is available, follow the onscreen prompts to download and install it. This may take several minutes to complete.
• Once updated, your LG TV will restart. Try installing your desired app again to see if the update resolved the issue.

3. Free up storage space:

• Go to the "Settings" menu, select "General", then choose "Storage & Reset". Select "Storage Manager" or "Memory Manager".
• Review the available storage left on your LG TV. If less than 500MB, you'll need to delete unused apps and media to free up space.
• Choose unused apps or media you no longer need and select "Delete" or "Uninstall" to remove them from your LG TV.
• Try installing your new app again with the additional storage now available.

4. Check internet connection:

• Make sure your LG TV is connected to your wifi network or Ethernet cable. Select "Settings", choose "Network" and select "Wi-Fi" or "Wired Connection".
• If wifi, check that your network name appears, signal strength is strong, and it says "Connected". For Ethernet, make sure cable is properly plugged in.
• Try rebooting your router by unplugging for 30 seconds and plugging back in. Disable any streaming on other devices.
• Try installing your app again after ensuring a fast, stable internet connection.

5. Check app compatibility:

• Open the LG Content Store on your TV and find the app you want to install. Select it to view the details.
• Look for any mention of compatible LG Smart TV models. This info is typically listed under "Requirements" or "Details".
• Ensure your specific LG TV model number is listed as supported. If not listed at all or only newer models are supported, the app likely won't install properly on your TV.
• Unfortunately, if your TV model isn't supported, you won't be able to install that app. You'll need to choose another compatible app.

6. Disable antivirus software:

• On the network your LG TV is connected to, disable any antivirus or security software running on your router or other connected devices like laptops or gaming consoles.
• Antivirus software can sometimes detect new app installations as a threat and block them. Temporarily disabling protection will allow the installation to proceed uninterrupted.
• Navigate to your router's homepage by entering its IP address into a web browser. Look for an option to disable antivirus, firewall or intrusion detection and select it to turn off.
• Alternatively, open your antivirus program on a connected laptop or other device and select "Disable" or "Turn off" to temporarily disable protection.
• Try installing your app on the LG TV again with antivirus disabled. Don't forget to re-enable your security protection once the installation completes!

7. Try again later:

• If you continue encountering issues installing your app, the problem could be temporary. Try waiting a few hours or even a couple of days and then try again.
• Problems on the app developer's end or with your internet connection or router can sometimes resolve after a period of time. Waiting and then retrying the installation is an easy first step before other, more technical solutions.
• When you try again, restart your LG TV and router first to refresh the software and network connection. Then attempt to install the app again from the LG Content Store.

8. Wait for other downloads to complete:

• If you have other apps, games or software updates downloading or installing on your LG TV at the same time, it can overload the system and cause your new app installation to fail.
• Check the notification area on your LG TV for any messages indicating other downloads or installs in progress. Wait for them to finish completely before trying to install your app again.
• Multiple installations running simultaneously pull bandwidth, storage space and can sometimes conflict with each other. Once other downloads have completed, restart your TV and retry installing your app by itself.

9. Check for known issues:

• Do a web search for the name of the app you're trying to install along with your LG TV model number. Look for any search results indicating compatibility or installation issues.
• You may find forum posts from other LG TV owners reporting similar problems with tips to fix it, or see that the app developer has listed some known issues that they are working to resolve soon.
• You can also check the app developer's official website or social media pages for any notices regarding your LG TV model. They may have guidance on troubleshooting or news on when an update may be available to fix the issue.

10. Factory reset your LG TV:

• Resetting your LG TV to factory default settings should be a last resort, as it will delete all your accounts, apps, saved wi-fi networks and personal preferences. But it can resolve persistent app installation issues when other steps have failed.
• Go to "Settings", select "General", then choose "Reset to Factory Default". Follow the prompts to confirm and your LG TV will reset and restart. The process can take up to 10 minutes.
• Once reset, you'll need to go through the initial set-up steps again from the beginning. Sign in to wi-fi, any streaming accounts and re-customize settings. Any apps you want will need to be reinstalled.
• After a factory reset, try installing the app that was previously giving you problems. The reset will have cleared out any software glitches or conflicts that may have been the cause of the issue.

Following the steps in this guide, you'll be able to find and install new apps on your LG Smart TV in minutes. You'll have instant access to live TV streaming, movies, music, sports, news, and so much more—all from the comfort of your couch. 

With new apps constantly being added to the LG Content Store, there's always something new to try on your TV.
