I live in France; until now I didn't need servicing for the unit but I asked yamaha france to connect me with a competent technician for disklaviers in my area (or any area ) and they couldn't do that...! they told me to contact a dealer (any) and proceed from there... This advice was a disappointment for me since I find myself at the mercy of a dealer which are all too quick to point out that i didn't buy py piano from them so... Since I have not succeeded in finding a specialized person (just to overcheck my whole system, nothing being basically broken). Im contemplating asking a uk person... So this behavior in France is not very surprising they are not good here with the notion of after sale service (I found the same with Apple france for exemple compared with apple uk or canada or even italy).
