naneek 0 Posted November 7, 2013 Hi, I am new on here so if this is in the wrong place or already has a thread I apologise! I have a Nevio EVS410 video encoder with 4 BNC outputs. The board itself needs to fit inside a pod and for that reason the 90 degree connectors have to be changed to straight. The card worked before I changed the connectors but once I changed them over the picture becomes black and white and rolls vertically down the down screen. Nothing else has been altered. I am an electronics student and apart from having melted something whilst soldering I cannot think of any other explanation than crap connections. Any help would be greatly appreciated otherwise work is gonna kill me! Lol. Share this post Link to post Share on other sites
ssnapier 0 Posted November 7, 2013 How did you re-terminate the coax? It sounds to me like you just have a badly terminated cable (or several) and my suggestion would be to get new connectors and do it again. Most installers prefer to use the crimp on style connectors, and my personal preference is to buy the ones that have the center conductor already in place so you aren't crmiping that tiny little pin. Also make absolutely sure that you have NO shield wire.... let me say it again... NO shield wire touching the center conductor. That will cause all kinds of weirdness, and generally is one of the causes of the rolling you described. Here are two videos on how to terminate RG-59 using a BNC: This one is just for crimp on: fVtaRWiK5jo This one covers all the common stuff: VfWmwP9Hbj0 Share this post Link to post Share on other sites
