Hi Guy's, I am wanting to create a video out port on my fish finder so that I can hook the video to a larger screen that will be viewable from a further distance in the boat. I have a 15 inch led monitor that runs on 12 volt with a variety of ports on the back that can be used to input the video to. (HDMI, USB, VGA, RGB, and AV). I have the Fish finder apart and found that the existing screen is being run by a flat ribbon cable with 44 conductors. The majority of the components on the board are surface mount. I do not have a schematic for it and the manufacturer is not interested in helping to supply a schematic or are willing to perform the task for me. I have a bit of experience soldering on boards and have built a few gadgets in the past with success. I would really appreciate some help in designing a circuit and tapping into the video signal so that both screens are displaying video at the same time.
