What kind of piano is this? It could be a broken rep spring, (or one that is out of the grub), if the action had thread loops, one of them could be broken, I have even seen this happen when a backcheck leather finally wore in two and one of the pieces captured the hammer below the point where the action could reset. I have also seen this when the rep lever post had come unglued. What kind of piano? Regards, ED Foote
