The Samsung TV receives a connection from streaming devices via the cable wire. Once the TV fails to receive signals, you will experience the Samsung TV black screen of death error. There are some common causes of the failure.

  • Loose cable ports/connection
  • Inactive power sources
  • Improperly plugged cables

If the screen is black when the LED light of the Samsung TV is on, it is likely that the TV’s cable connection is loose or faulty. It is recommended to check the status and connection of all the TV cables after the Samsung TV screen black issue occurs.

Ensure that there’s a proper cable connection between the external sources and Samsung TV. For that, you can unplug all the cables and then plug them back.
