Over the weekend I was fishing and around noon my 360 screen (Helix 12) just blacked out and stopped working. It was working perfectly fine all morning Saturday then shut off. Sunday didn’t work at all. Every other function on the Helix unit itself worked perfectly fine. When pull up the 360 view can see the little radar style line moving in circular motion except the circle is 100% blacked out with no reading. I tried to trouble shoot it by turning off the unit several times, stopping the ping then restarting. I’ve tried the basic stuff. Any suggestions? Would a loose wire at the hub be causing this. I’m assuming a loose wire could be possible since it just stopped working when it was working perfectly fine? Or I’m guessing something with the 360 just went out?. Clueless
