Anyone ever had hummingbird fish finder problems ?

I have a 788 hummingbird fish finder and when I turn it on the screen just flashes. It worked fine for the first two years now the screen just flashes. I have tried a new transponder and still does the same thing.

Anyone have these problems ?

Power problem? Check power cord connections, wiring and battery.

So, is it working now?
