I have a furuno radar model 1800 from late 80's when in turns on it has a x 14 in the upper right hand corner of screen I don't remember seeing this I forget, it worked fine last year and is giving me problems this year it works has power and sweeps but I can usually only see land or objects for one sweep then they disappear . I noticed on plug that attaches to monitor in back might be missing a pin any help would be thankful chris , I have been trying to tune in front not back yet per manual as it did work fine
