Your favorite hospital drama just dropped a new season. But several minutes into the show, the streaming app on your LG TV starts buffering, then freezes. The situation isn't looking good—will clearing the cache on the LG TV help?

Sounds like a problem for Asurion Experts. We help millions of people keep their tech running smoothly. Here's how to clear the cache on an LG Smart TV so you can get back to your show.

Why LG TVs don't have a clear cache button

Before you start digging around the menu options on your device, know that there is no specific LG TV clear cache option built into individual apps. Instead, newer devices feature it within the Web Browser application or Memory Optimizer tool. That's where you'll want to go to delete the cache for all apps.

If you have an older device that lacks a specific clear cache on LG TV feature, there are alternatives. Power cycling or clearing system memory can help.

Clear the cache on your LG TV

Try these solutions to clear the app cache on an LG TV:

1. Run Memory Optimizer

Some LG OLED models have a built-in Memory Optimizer you can use to delete background data. If you're unsure whether your device is an OLED, find your TV's model number on the back label. You'll see "OLED" within the model name if it is one.

To clear the cache on an LG OLED TV, take these steps:

1. Open the All Settings menu.
2. Click General > OLED Care > Device Self Care.
3. Click Memory Optimizer > Start.
4. Wait for the TV to restart before using your streaming app again.

2. Power cycle the TV

A full power cycle erases your device's temporary files and may stop apps from lagging or freezing. To perform a power cycle on the LG TV and delete the cache, try this:

1. Turn off the TV and unplug it from its power source.
2. Press and hold the Power button on your TV for 30 seconds.
3. Wait at least 60 seconds before plugging it back in.

Restart your LG TV after the power cycle to see if that helps.

3. Delete and reinstall the streaming app

If you're still having trouble, you can try reinstalling apps on your Smart TV. This is a dependable way to clear the cache on an LG Smart TV with your remote, but you will need to re-sign in to the app.

1. Press Home on your remote. Click Edit App List.
2. Locate and click the app you want to delete. Click on the Trash icon. Click Yes to confirm the deletion.
3. Press Home on your remote. Click Apps > Search icon.
4. Enter the app name and select it from the search results. Click Install.
5. Wait for it to download before signing in.

4. Clear the web browser cache

Some TVs have a Web Browser app that includes an LG Smart TV clear cache feature. Taking advantage of it may resolve buffering and freezing issues. Here's how to locate it:

1. Enter the Home screen and open the Web Browser app.
2. Click Menu > Settings > Clear Browsing Data.
3. Click Clear Cookies and Clear All Browsing Data.

What to do if apps are still slow

You have a few options if other LG TV clearing the cache methods don't work.

• Update your TV's software: Outdated software may cause apps to glitch.
• Check for app updates: Make sure you have the latest app version, since an outdated one may freeze.
• Use stable Wi-Fi: Check your LG TV's Wi-Fi connection and move the router closer for optimal performance.
• Delete unused apps: This frees up space on your device, giving it more room for temporary data.

A factory reset is another option, but only use it as a last resort since it completely erases all your user settings. To perform one, open Settings, then click General > System > Reset to Initial Settings.
