Hello MB19565,

The following would be recommended given the reported symptoms:
- inspect the transducer for signs of fouling and remove an fouling found
- if the transducer is a transom mounted transducer, ensure that the transducer's kick-up bracket has not been triggered. The transducer should be locked into its down position.
- inspect the transducer for signs of damage ... replace or test with another transducer for isolate the sonar fault
- a Sounder Reset should be commanded from the MFD's Fishfinder menu.
- System Settings and Data Reset should be commanded from the MFD's Diagnostics menu. Any waypoint/route/track data of value should be backed up prior to performing this action to permit them to be imported back into the MFD's memory after having performed the reset.
- the Transducer selection menu option should be exercised within the Transducer Settings menu of the MFD's Fishfinder application. The model of transducer installed onboard may be verified per the FAQ found here. https://forum.raymarine.com/showthread.php?tid=794

- should the MFD be reporting the symptoms specified, then it would be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked
