Furuno probably wouldn't want to get into it becuase it could also involve the waveguide, magnetron, MIC, TX board, IR board, Motor, and Chasis. Taking it apart, figuring out whats needs replacing and replacing it might cost more than just buying a new one, and would leave you with a questionable unit there after- if they don't replace the Mag, and it goes bad six months down the road, would you expect them to warrenty it, knowing the unit took a hit?
You may get lucky at a local Marine Electronics Servicing Dealer, but they might turn it away as well.
