@marapet Did you ever find a solution for this problem? I was getting perfect recordings from mine, but the DVR and the linear regulator that I was using were getting too hot for my liking. I switched to a DC-DC converter, which took care of the heat, but I have noticed that the quality of my recordings has gone down and I'm getting these pulsing diagonal lines.
Sorry for making a new thread about this. I couldn't figure out how to DM or post a reply
