Picture flickers with HD SDI system

[Dust_man_99 0]

Hey everyone, I had a question about my "Black Series" HD SDI camera system. I have it all set up, but the picture flickers on and off and it says " Video Loss" in the center of the screen. Its a good picture, but the flickering on and off is annoying. Any ideas? I appreciate any help.

HD-SDI operates on a very high clock speed around 2 Ghz. Very vulnerable to cable conditions. Please make sure of tight coupling all along the input path, not to be loose in connections. Can you state how long the cable is. I mean how far from the camera?
