I have a 2 year old Carbon with ATS 1 powered by it's own battery. Has worked flawlessly until the last two trips. The screen goes blank only with vertical lines. I have to remove the power connection and shut it off. The first time it happened I left it off for a couple of hours and fired right back up. So I thought it maybe overheated. Today it did it again after about 2 hours of fishing. Anyone have this problem before? I starting to think maybe a bad connection or jiggled loose.
