For many months all has been working well. Then recently (nothing was touched) ch4 stating lost video.
- rebooted the box, nothing
- swapped the BNC cable with another camera, all works for 2 seconds and video is lost.
So no matter what I do ch4 comes up for 2 seconds (when I switch the to a different channel the video) and then goes away. How do I trouble shoot this?
ps
Any other video I put on ch4 works. ONly that one cammera on any channel will only last for 2 seconds.
