    This is something that should be taken to the dealer for repair.

    From reading a little on it, it sounds like it's most often the inverter/converter. If it were me, after inspecting wires and stuff I would probably look into a used one to swap out and if that doesn't work just re-sell it. As was mentioned though, it's probably best for a professional to do it since you are dealing with electricity. I deal with electricity for my job so I'm comfortable with it.
