Default Depth Finder not reading

I have a Humminbird 788ci and for some reason the depth isn't showing. I went through some rough water yesterday and hasn't worked since.

I restored factory settings and nothing. It's not even showing a number where it should be.

Hello, is the boat out of the water? If so a little tip, turn on the unit for depth, put your ear under the transducer and listen for a faint "clicking", if you can hear it, the transducer is emitting, if not it might be not working, check the wiring to the unit (screen) for any loose connections. Hope this helps.

You say it stopped working after running through rough water. That makes me think that you may have lost good contact with the cable prongs in the base. This can happen with the quick connect bases. Try removing the head from the base, make sure each cable is seated well and not loose in the base and then reseat the head. If you are lucky, you only lost contact of one or more cables due to the jostling from the rough water.
