Hi, I am having the same problem on my Casio AP-250. The shooting sound is equal to the one shared by brucepedalty, and happens when I only hit one of 3 keys in the higher register. I'm attaching a video so it's more clear. I can hear the sound also when using headphones, so it's definitely not the speakers but an electrical fault. The problem started yesterday, after almost 3 years of owning the piano. I will go tomorrow to the shop where I bought it and hope they will find a solution to this, it's very annoying and makes playing impossible.
