Before I even called lowrance originally the first thing I checked was the power cable and it was getting full power. I replaced the power cable with the brand new one supplied in the AT box and bam. That was the issue, for some reason the power cable was causing the issue even though it was getting power. So replace power cable with new one and see if that works.
