Does it work in simulator mode? If it does I'd say you have a bad transducer or pinched a wire.
Works in simulator mode. HB Greg and another good trusting soul gave me some ways to test the problem. rnvinc loaned me a transducer to test the control head. Then when I got home I HB Greg posted on another forum how I could use my 788 to test transducer after changing some settings. This is something that the lady at customer support didn't know how do do. It is good to have the people @ HB watching these forums

Thanks all
