check the power supplier and replace it with a new one if neccessary.
Some channels display just a black screen even if
they receive video sources.

image. Sometimes, this problem may occur on a camera that is not
properly connected to the video source.
Check if the camera is properly supplied with power.

from a video distributor that is connected to multiple systems. In this
case, input the video source of the camera directly into the DVR. This
may find the cause and solve the problem.
