Yes, I think it’s the screen driver going out as well. Issue will occur regardless of voltage. The video I posted was taken three hours after I just received the unit back from Humminbird, after the charged me $300 for the repair. When I asked what they did for the repair they told me they installed latest updates and reset the unit. Ticks me off since I sent photos of what the unit was doing. I just emailed them a link to the YouTube video, and now they tell me it is corrupt data, and the solution is to delete all nav, tracks, and waypoint data. I deleted everything two years ago, when the issue first occurred. Hummingbird tells me the link on YouTube doesn’t work, but I’m guessing you guys didn’t have that issue. They’re telling me it’s corrupt data on the unit, but didn’t bother to fix it when they repaired the unit last week. They also didn’t bother to check out the video of the issue. Anyone out there ever have the issue of corrupt data causing similar screen issues?
