Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

The screen coming out upside down does not seem to me to be the fault of the transducer at all.

Add to that, lines on the screen... and I think it is fair to say, you almost certainly have a defective Furuno 585.

It will need repair or replacemnt. This sort of thing is not likely to be a transducer fault at all.

But the transducer might be improved by having its connection checked, cleaned, and re-seated. Ask me for directions if you're interested in trying this in a manner that is likely to be effective.
