fernandotcl Posted March 3, 2018 Share Posted March 3, 2018 Hi, I'm hoping you guys can point me in the right direction. My 3-4 year-old Privia PX-150 had been turned off (and unplugged from mains) for a few months. I turned it on and started playing today, but noticed something very weird: when I play D2, D2# or E2 and hold the key down, I hear a loud clicking noise coming from the left channel in addition to the proper sound of the key. Here's a video showing the problem (note that C2 is fine, it's only specifically D2, D2# and E2): Note also: - It doesn't matter if I'm using headphones or the built-in speakers. - The loudness of the noise seems proportional to the loudness of the sound produced by the key press. - It's definitely electronic noise, not mechanical. - The problem persists after disconnecting the pedals. I'd be very thankful for suggestions on things to try before figuring out how to get this to a repair shop... Cheers, Quote Link to comment Share on other sites More sharing options...
fernandotcl Posted March 3, 2018 Author Share Posted March 3, 2018 Something else that I tried: the demo songs also trigger the same problem when they play those notes. So clearly not related to the key mechanism itself. Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted March 3, 2018 Share Posted March 3, 2018 Are you still under the 3 year warranty? Quote Link to comment Share on other sites More sharing options...

Brad Saucier Posted March 3, 2018 Share Posted March 3, 2018 In that case, hurry. That unit needs repair. You can find Casio service contact info on their main support site for your country. I'm guessing Europe? https://www.casio-europe.com/euro/support/product-repair/musical-instruments/#tab Quote Link to comment Share on other sites More sharing options...

Stephan Posted August 27, 2018 Share Posted August 27, 2018 Ha, seems exactly same issue as with our AP-650. Did you get yours repaired and do you know what was done? (Ours is unfortunately out of warranty.) Quote Link to comment Share on other sites More sharing options...
fernandotcl Posted August 28, 2018 Author Share Posted August 28, 2018 No, I didn't. Mine was actually out of warranty already, turns out. So I'm still unsure what I'm going to do. I'll post it here if I eventually get it repaired. If you do get yours looked at, please let me know! Quote Link to comment Share on other sites More sharing options...
Pavan Kumar Kamaraju Posted November 15, 2023 Share Posted November 15, 2023 Sorry about bumping this thread after an elapse of few years. Exactly the same problem occurred with my Casio Privia PX-150. The service engineer from Casio, Hyderabad checked it, and said it is a motherboard problem.

Brad Saucier Posted November 16, 2023 Share Posted November 16, 2023 Unfortunately that's correct. Fortunately, the issue is usually isolated to the stereo piano tones only. It may be possible to continue using the keyboard with those other tones normally. It's also possible to use the keyboard as a USB MIDI controller with software sound sources like Pianoteq.
