I thought I would give you all an update to the loud popping sound I heard on my Privia PX350. It turns out that the popping sound was due to a bad CPU. Casio honored the warranty and the music shop I brought it to ordered and replaced the CPU and the problem has been solved. It seems that the issue is not a common one. The tech at the music shop had never heard of it before. I guess I just got a lemon.

I found this forum to find a solution to the EXACT problem on my Privia PX350 that Cinderfella has posted. I too get what I call a popping noise when in the piano bank when I depress the sustain pedal. It doesn't happen all the time but when it does, it's usually a series of 4 or 5 loud popping sounds. Also, I do believe the sound is coming from the left side of the keyboard as someone else has reported. I am quite certain that this is in no way a normal function of the keyboard. I am a pianist and have played several digital pianos and keyboards as well as acoustic pianos and have never heard this sound before. I have owned my Privia 350 for exactly 2 years and it has just started making this noise. I have to say that because I also have an acoustic grand piano, I have not used my keyboard very much but now that I have retired and want to record my own music, my keyboard has developed this malfunction. So yes it's 2 years old but I probably played for only a total of a couple of weeks. To say I am very disappointed in this is putting it mildly. As a matter of fact, as I am writing this, my keyboard is at a music specialty repair shop certified in Casio repairs getting the problem diagnosed. Hopefully the problem will be detected and will be able to be fixed. I even recorded the popping sound on my phone and played it to the technician to hear. Like many people have said here, he has never heard that sound before. Fortunately the warranty is within the 3 year window. I will update this post after the findings from the repair shop. I really like the keyboard but it is virtually unplayable making those sounds for a pianist performing in entertainment venues and doing gigs. I have attached a video/audio where you can hear what the popping sound is like. Ignore the static sound throughout the video which is coming from me holding the phone while playing. You will hear 2 series of popping sounds each having 4 to 5 popping sounds. 20161016_093349.mp4
