Lowrance Elite 5 not reading water temp?

[Pikebreath]

My Lowrance Elite 5 has started flashing 32 F constantly,,, I can't seem to find anywhere in the settings that deals with water temperature,,, restoring defaults doesn't fix it.

I suspect could be transducer problem,,, anyone else have a similar problem and what was the fix?
