My 94 yr old neighbor has this piano with 2 problems
1 the middle E key not spring back. How6if pressing it successively, it springs back.
2 whenever i turn the piano on, it gives a high pitch sound…like distorted electric guitar…when I press the keys, they all have a high pitch resonance. I have yo turn off then on several times , then the noise subside. The keys play normally with no distortion.
What could be done?
I have got a service schematic manual. I have taken out the bad key, it doesn’t look dirty. I could see the spring(22175178Key Spring) but no idea if it is the culprit or not.
Would appreciate your reply
Thanks in advance
