My first Humminbird Gripe!
Got my 797 back today from getting worked on at Humminbird customer service (they said it was something wrong with the "board"), put it in the cradle and it will not get past the loading screen. I tried both cradles that I have in the boat and same result. Cost me nearly $200 bucks and doesn't appear they even checked it before they left the service dept. Took the battery out thinking it might be something with the battery and replaced it with another. Same thing!!!!
Here is the real . Let me preface this by saying that both are my units have a 1 amp inline fuse between it and the battery, so this shouldn't be related to anything that I have done regarding wiring. Put the 777 on the cradle and it is doing the same thing as as the 797 was. "Blurred" screen, and everything is shadowed. Must be the board on this as well. I am going to send them both back. I ran both of these units exactly the same way the last 2 years and had no problems. I can't believe both these units decided to crap out at exactly the same time!
There goes another weekend without being able to fish!!!!!!!
