How do I fix a black screen on a Samsung TV?

Last Update date : Jun 04. 2024

A black screen could just be a sign that the TV is turned off, although if it is producing sound then you know that's not the case. When your TV has a black screen even when it's on, it could be an easy way to fix the issue, or it could be more complex and require professional service. To diagnose your issue and narrow down the problem, follow these steps.

  • If the menu is cut off by the black part of the screen, visit the Support Center or contact us to request service.
  • If the menu displays completely, service is not required, but the following steps will help you identify a resolution.

Some TVs have an HDMI cable test. Some models only have this test after a software update, and older models do not have it. If your model does not have this test or is not connected by HDMI, skip to the next step. The test is designed for HDMI cords less than 6 feet long and may not give accurate results on long cords. 

To perform the test, make sure the TV's source is still on the HDMI setting for the cable you want to test.

You can find the Self Diagnosis in the Device Care menu. Navigate to Settings > Support then select Device  Care  > Self Diagnosis > Signal Information > HDMI Cable Test > Start Test.

If the test says the cable is bad, replace the cable. Service is not required.

For models before 2020, navigate to Menu > Support > Self Diagnosis.

Try connecting a different device or using a different Source port. If you were unable to test the cable in the previous step, then try swapping the cable too.

If the TV can display a picture in any other setup, then the TV is not the cause of the issue. Keep trying various setups until you identify the device or cable that is not working, and then troubleshoot or replace it.

If none of the troubleshooting steps above solve your problem, visit the Support Center or contact us to request service.
