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,
