This inquiry has been posted two weeks ago, but so far, NOBODY seems to know factory-supported service solutions for Sony mics or can recommend an experienced independent technician with access to Sony schematics and parts?
How does this company sell microphones in a country without official service support (which, to my knowledge has been the status for at least 25 years now)?
I can recall two other, well-known professional condenser microphone manufacturers whose similar lack of proper parts and service representation in the U.S. not only reflects badly on the products (among the best in the world, in my opinion) but on their sales in the U.S.
The logistics, costs, and time delay of shipping expensive, fragile mics which sometimes only have minor issues to another continent for servicing is nightmarish, especially when you add customs and duty hassles and costs.
Some companies use the convenient solution to delegate responsibility to a third-party agent in the U.S. who acts as shipper and intermediary. But that, too, is not appealing to me. Often too much of a client's concerns gets lost in translation before the mic reaches the intended recipient.
That is why I routinely recommend to clients NOT to buy products, all-else being equal, whose manufacturer is not willing or financially capable to invest in proper parts and service support for the product they are nevertheless eager to sell here.
