Humminbird Helix 7 Display Problems
I have a Helix 7 at the console and bow. The bow Helix is glitching, dim display, and sometimes reads upside down. Now the screen is so dim I cannot even read it. I put the other Helix on the bow and ran it independently and it works. I also put the bow Helix at the console location and it still does not work. My cranking battery is almost five years old but fully charged so I don't think it's a power issue. I know the flat rate for Helix 7 repair is $189.95, but was wondering if anyone might know what the issue is before I have to send it off. Again, I don't think it's a power issue but let me know if you think otherwise.
