Raymarine transducer no signal

Raymarine transducer comes up no signal on both my displays a75 and e97 I've been away and not used the boat for 9 months I've checked the wiring and connections all look fine has anyone had this problem before? Also I've been to white worths and they don't have any in stock

Check for power coming from the head unit

If you have got a mega (voltage meter/circuit meter) check to see if there is any power going to the transducer from the head unit. That is what it sounds like to me, no power to ceramic plate in transducer no signal or noise.
/vibration.

Remove transducer plug from head unit and use mega to find voltage pins if you have a booklet for the unit this should hopefully show you which pins to check.

 Don't use a megger or you probably will damage the unit. 

Does the tranny plug into a sonar module first?
