Thank you for some positive feedback! If the spare parts are on stock and it is not a major issue, the turnaround time is usually very good. Also the good thing is that the spare parts and components used on the MR devices are at least partly identical to the ones Yamaha uses which makes any repair easier at the service center.
As I said, they fixed it with no charge. I originally bought 6 MR’s so that may have influenced their decision not to charge me anything. In any event, different problems might cost different amounts to repair.
We don’t make a difference if it’s one unit or six (sorry Chris ) and I can only speak for most parts of Europe here but if the device is still under warranty, the repair is free of charge.
Our repair center is also working for Yamaha so most of the times, spare parts are on stock and the repair is done within 48 hours.
For an old second hand unit, the repair time is the same but the repair won’t be free of charge anymore of course. The repair center can provide a cost estimation though.
