Last Update date : 2024-01-05

If you are having trouble with your TV, you may think it's better to reset and start over. Although it could be one of the solutions to its problem, it may not be necessary. Your TV also has several built-in self-diagnostics to help you troubleshoot problems with your video, picture, sound, and many other things.

Optimize your TV with Device Care

Device Care is TV diagnostic software based on TV data that shows the current TV's operation status at a glance. When you enter the Start Device Care menu, Device Care diagnoses your TV and shows a list of the issues and status your TV currently has. TV operation status is notified in two stages and is divided into good and moderate. You can access Device Care in the Customer Support menu.

You can also check and clean your storage space, diagnose problems yourself, or request technical support. When the TV diagnosis is complete, it clears the cached memory, frees it, and closes unused background apps to free up memory. Please follow the guide below on how to run a Device Care scan on a Samsung TV.

In the Self Diagnosis menu, you can test the various conditions of your TV directly to determine if there is an abnormality. If problems are being caused by the TV itself, use the video test, picture test, and sound test to determine the cause. You can also check HDMI, network signal, and Smart Hub connections in this menu.

  • Video Test: When you experience a problem with your TV's video quality, use the Video Test. The test video will be played with the highest quality on your TV, and then you will look at the screen carefully for a few seconds to examine for flaws.
