My fish finder isn't showing depth or temperature anymore. I was fishing one day and my temp started blinking and went away, then my depth began blinking and went away. Soon after this my screen wasn't showing any structure or anything. When I run my self test it shows my temperature is unconnected, but my temp is built into my transducer. Could this be a faulty transducer?

Yes... or it is unplugged... or the wire is broken...
Typically you hear a clicking sound at the transducer when it is powered and running but in your case all function is missing from the display and temp and depth is off of the transducer..
