Ghost ? Carbon 12 ? 3 in 1 transducer ? Or network

Well not sure which is the culprit. Have 2 carbon 12's, a ghost tm, 3in1 on the ghost. 1st i should say the ghost is no longer showing on the device list on the carbons. The ducer is giving a inacurate temp reading and side imaging is a line down the center with black panels on each side. The side scan defect just occured today. The temp and device list a few weeks ago. Have checked network connections all are snug. Talked with lowrance rep last week he sent me instructions on resetting ghost. I did as instructed. Today was first day on water since reset and 1st time side scan problem. He also mentioned it could be circuit board under foot pedal. I believe updates are done automatically. Any advice would be greatly appreciated.

Untill your Ghost shows up on the Device list NMEA is NOT working. The Ghost is controlled by NMEA 2000 Fix that and the rest may follow. Where you on the water when testing the Structure scan? It only works on water no driveway testing on that.

Yes, was on the water.
