I am working with a Mavo LF with the Kineback-W that we received about three ago. Suddenly, I cannot get an SDI signal out of the camera. It worked a couple of days ago, but now I do not get any signal. I have rebooted, changed cables and monitors, but still no luck. At the moment, I am running off of HDMI, but I need to solve this SDI problem. Any help is appreciated.
