How to use Device Care on your Samsung Smart TV

If you are having issues with your TV then Samsung Device Care could provide you with a solution. Rather than performing a reset or attempting another fix, Device Care is an in-built self diagnostic that can help troubleshoot many different TV problems. Whether it’s an issue with video, picture, sound or something else, Device Care is a highly intuitive way of diagnosing and fixing TV problems without the hassle.

Optimize your TV with Device Care

Device Care is a data driven TV diagnostic software that allows users to easily see their TV’s current operation status. When you enter the Start Device Care menu, your TV’s Device Care system will diagnose your TV and present a list of any issues with the appliance. It will also notify you of the TV’s current status which is presented in two stages and divided into either Good or Moderate. Once TV diagnosis is complete it will free up memory space by automatically clearing the cached memory and closing unused background apps. All of this will help to improve the speed and performance of your TV and may help fix troubleshooting issues.

In the Self Diagnosis menu, you can test the condition of your TV directly to determine if there is an abnormality. To determine if an issue is being caused by the TV itself you can use the Video Test, Picture Test, and Sound Test allowing you to establish where the issue is. You can also check the HDMI, network signal, and Smart Hub connection using this menu.

  • Video Test: When you experience a problem with your TV's video quality, use the Video Test. A test video will be played using your TV’s highest quality. Examine the screen carefully to check for any flaws.
