Brand new unit just recieved it yesterday and wired it up yesterday afternoon. After playing around a little this afternoon I would believe it to be be a bad filter circuit and maybe even a rectifier, I put a rectifier on the supply and it clened up some, but it was even better when I addded a filter Cap. I aslo called JVC and the tech there suggested that the camera was the problem. At first I figured I needed to jumper something or change a DIP. Thanks.
