Dear List, I have a puzzler for anyone out there who is familiar with the new Mark III Yamaha Disklavier pianos. We got a new DGH1BA MkIII in the other day, and the first thing we noticed, after I tuned it was that the keys were bouncing all over the place upon playback. After tightening the screws, and bedding the keyframe, doing some minor regulation, everything seemed pretty OK (which most Yamaha pianos seem to come in at least pretty Ok), I performed Soft and Loud pedal measurement. The answer was, pass, adjust loud pedal. After setting the loud pedal to the specs, it still said to adjust loud pedal. Then I did Keyboard measurement, and came up with a lot of keys with pass numbers, almost all of which were pedal numbers (18,28,38) in both pedal phases. I went in and adjusted the pedals again today, and when you get the bottom measurements to spec, the top doesn't work properly (bad lift, timing is wrong). When you get the top working as it should, the measurements are way off spec. To top it all off, I noticed a "clicking" sound when keyboard measurement was going on, and I found a solenoid laying across some other solenoids, way out of place. Any ideas out there, all you Yamaha experts? I need help, and Yamaha didn't call me back in time today (although I'm sure they will). Clark Sprague Associate Member Detroit
