Samsung Microwave hit with 220V

[BestWitted]

I have a Samsung MR5492W microwave that is installed in a trailer as standard equipment. I recently had an electrician inadvertently send 220v to the circuit that the trailer was plugged into. While the microwave was not running at the time, it was plugged in. I see no obvious damage on the circuit boards but there is no working display. Fuse is ok but lacking a schematic…..I have no idea what to pursue for a fix. Any ideas on the most likely spot for damage to occur when plugged into 220v instead of 110v? Thanks, Dave
