Unit was working fine until transducer started going out so I replaced it now everything is working except the down image. It starts to work then what looks like a tight woven fabric pattern takes over and scrolls across the screen. the rest of the locator works just fine its just the down image that has the problem any one have this problem do you think the new transducer could be the problem since i didn't have this problem until i changed the old one out. I moved the wires thinking interference that didn't help
