Denon Receiver Tech in BR

My Denon AVR-2310ci that I use outside must have gotten wet when I was cleaning with my pressure washer .

When I turned it on I heard a pop and saw a spark underneath the unit.
It powers up but then the power button starts blinking red.

Is it worth fixing and were in Baton Rouge should I take it?

I like the Denon because I can use Zone 2 to listen in a different area.
It looks like somethin new would be over $300.
