I have not seen this piano yet but am doing a service call tomorrow on it. A church purchased a new P22 and it played fine at delivery. However after one night the pianist is encountering all sorts of issues in the mid section and above. Keys are sticking, trouble with repetition and response, slow hammers, problems when the damper pedal is used. backchecking and blocking hammers. The piano is in a small church choir room in which the temperature is kept in the 70's. I suspect there is a humidity issue based on my years of experience with the issue on the South Carolina coast and inland. We have had some rather wild weather swings of late with some heavy rains but also cold temperatures at night going warm to hot in the day At the moment it is 73 but going up to 90 today . Churches and schools are not known for their control of the environment and many air conditioners fail to do the job they need to do. I have solved many humidity piano issues with Dampp-Chaser installs but that may be something down the road for stability .
My question for techs - have you had any new P22's in the past months with problems like this ? My first approach will be to assess and document all of the problems I find followed by doing some action center testing, checking the letoff rail position, lost motion, damper timing, backchecking, bridal strap slack, action tightness, action brackets, blow, backcheck distance, letoff distance, pedal rods, Key fit need to ease bushings/ease balance rail hole.
Of course I plan to have a temp and humidity gauge to record what the environment is and will possibly place a data logger.
From what I was told the piano was fine right after delivery and had none of the reported problems.
Could there be a structural issue ? Could it be poor factory or dealer prep ? I doubt it because Yamaha pianos I have seen have not had issues although I have not seen any of the new uprights....
