Your TV may display a black screen if it's connected to a source but the external device is turned off. For instance, if your cable box is connected to HDMI 1, you should set the TV source to HDMI 1 and make sure the cable box is turned on.
If the TV is set to the correct source, but there is still no image, unplug and reconnect the connections one cable at a time, from both ends of each cable. If there's any damage to the cable, it will need to be replaced. After you've reconnected the external device, turn it off and then back on.
