One CCTV monitor has a blue screen, how can I solve it?

A. 1

There is a possibility that a short has occurred on the line.
Check if the line itself is out of touch.

I had the same symptoms, but the problem was the camera adaptor, so it was solved after changing the adaptor.

In general, if there is blue, it looks like a line and blue, but if there is a logo, it is known as an adaptor and other power problems.
