TZTXL Side scan Intermittent No connection error

[Benfishin]

Recently professionally installed brand new Furuno TZTXL suite that includes side scan. Three MFDs, radar, autopilot. Hub 102. Everything works well except the side scan.

When I touch the side scan icon it enters side scan mode and sometimes gives an beep and error message with a white screen displaying "no connection". After sitting for a few minutes it will then connect and work providing images on the screen. Randomly it will lose connection and start beeping again. I have checked the transducer cable connection at the back of the unit. Moving the transducer cable around at the unit doesn't seem to cause it to connect or disconnect . Transducer is on a flat pad on the rear of the transom as a through hull attachment.

Advice on where to proceed to look next?

Are you running a normal transducer on same unit that you are running the side-scan?

Are you running a normal transducer on same unit that you are running the side-scan?

Yes. When I run the sidescan I select it from the drop down menu.

Sorry, I guess I wasn't clear. The machine that you have your side-scan transducer connected to physically, do you also have a normal transducer connected to that physically as well?

Yes I have the side scan transducer plugged into the appropriate plug on the MFD and another transducer (B175L) plugged into the back of the same MFD in its appropriate plug. Those are on my starboard MFD and I have a B175 HW plugged into my port MFD.
