The simple times when a TV was just a flickering box to switch on and off are long gone. Nowadays, smart TVs are widespread. They come with all kinds of apps and functions that are either pre-installed or can be downloaded via an internet connection. Smart TVs are, therefore, becoming more and more like a PC or smartphone. While this brings many advantages, it can also create new problems. That’s why TECHBOOK explains how to clear the cache on your TV and when and why you should take this measure.

Smart TVs Also Have a Cache

Many people will be familiar with the cache from their computers, especially from their trusted web browser. “Just clear the cache” is also a common recommendation when you’re having trouble surfing the web. But why, actually?

The cache is a temporary memory where certain information from websites is stored so that it can be accessed more quickly in the future. This could be thumbnails or login data, for example. This can significantly reduce loading times, making the experience faster and smoother.

However, the cache can eventually become too full. Then, the opposite effect may occur. Instead of speeding up, the processes slow down. Problems can also occur, for example, if a page of information is retrieved from the cache rather than new information. This can lead to crashes or login issues. In such cases, users must take action. Therefore, it’s important to clear your TV’s cache as well.

Clearing the Cache on the TV — What You Need to Know

Clearing the cache on the TV can solve several problems in terms of memory, performance, and functionality. However, providing detailed universal instructions for this is not straightforward. After all, the procedure, menu navigation, and names can vary from manufacturer to manufacturer and sometimes even between individual models.

However, it is important to know in advance which information you really want to clear or delete. ZDnet points out that consumers can often choose between two options at the relevant point: “Clear cache” and “Clear data.”

While the former refers to the removal of temporary data, the latter means the permanent deletion of website information. If this includes login data, for example, you will have to enter it again manually. Thus, it’s recommended to start with the “Clear cache” option. You should only use “Clear data” if any problems persist.

How to Clear the Cache on the TV

A simple web search combining your specific device model with the query “Clear cache” should quickly yield the desired result. Generally, the process can be distilled into the following four steps:

  • Go to the settings of your TV.
  • Navigate to the apps or the app manager.
  • Select the desired app and look for the corresponding option to clear the cache in its settings.

Below, we provide specific instructions for several leading smart TV manufacturers:

LG

  • Press the “Home” button on your remote control.
  • Go to “Settings,” then to “General” and “Memory”.
  • Select “Clear cache” here.

Samsung

  • Call up the settings and go to “Support.”
  • Then select “Device maintenance” and start it.
  • Then go to “Manage memory.”
  • Select the app, look in the “Details,” and clear the cache there.

Android/Google/Sony

  • Go to “Settings” and then to the apps.
  • Select “Show all apps.”
  • Select the app and then “Clear cache.”

Roku TV

Roku devices don’t have a traditional cache. So if you experience problems, you should restart the TV. Alternatively, you can also remove and reinstall apps.

It is generally advisable to clear the cache on the TV regularly. Take action if your TV starts responding slowly, applications crash, or memory runs low.
