Ok I am in need of some help. I have used my 788CI HD DI twice this year, was going out for the 3rd. time and 788CI HD DI will not power up at all. I have check all the obvious… Battery, fuse, power at the plug at the fish finder and even check for voltage on the inside of the unit. All is good. I have contacted Humminbird and they sent an e-mail with all the usual checks. Everything checks good to what they wanted checked.
Anybody had this problem? And any possible cures. I can’t even reset it back to factory setting because it will not power up. Completely dead.
Thanks all… Any help is appreciated!
