Good morning, I'm hoping some one can help with this issue I'm having with my 7. I got the 7 back in Dec. and used it for my fishing trips.In March it started shutting off on its own and it was giving a message saying Repairing Files. I got a hold of Gopro and they said to send to them and they would replace it. So I did and I finally got it back after three weeks and I took it out this past weekend it started doing it again. I have it plugged into to my boat for a constant power source. I'm using a USB port that plugs into a cigarette lighter. I've tried with the battery in and with out the battery... Any help would be great.
