Are you talking about the loop ports on the system? If so how do you know they are not working?

not only the loop port, both loop & the main port (specific number 10) are not working.

If you have put the same camera on a different port and gotten a video, then I would have to say you have a DVR problem. I would say return it and get a new one.

 

I have seen even 4000$ DVR's arrive smashed to pieces inside.
