I have an l770 and another hsb plus display on my boat. I cant get a bottom picture on either machine. I have 2 dsp 250 boxes, 3 hsb cables, and have tried a few transducers that all work on other machines. Any Raymarine guru care to help? It worked for a few hours last friday then on saturday morning no go. The gps and radar are working fine. I spoke with raymarine and they did a little trouble shooting and said send it all back to them. The dsp has a solid amber with the display off and a blinking amber with the display on.
