I was doing a web search and came upon my old post. Here's a followup. My PX350-M was a fine keyboard for me but when it became evident that there is no fixing this issue, at least not at a reasonable cost, I decided that the time had come to buy a new one. I looked at a number of models from different brands in the mid-price range. Because I had been happy with my Privia until it failed I was drawn towards something like a PS-X3100 but ultimately I had to decide if I wanted to spend more money with a company that had already sold me a product that I was unable to get any meaningful support for. My answer was no, I am not willing to do so. I have a Roland PF-30X on order now. It comes with a five year warranty and for 43 Euro more I was able to extend that to ten years. As Brad mentioned the Privia still works fine as a midi keyboard or with non-piano sounds. I will keep it around an maybe experiment with it as a keyboard for software synths.

Thanks, that's kind of what I had guessed.

It was initially the grand piano sample but it seems to be spreading to others. I tried the reset a few times and it didn't seem to be helping. These things are pretty complex and no doubt beyond my abilities. I guess I'll get as much use out of it as I can.

Hi Guys, Thanks for the replies. Sorry that I'm slow responding but life got complicated for a while. Here's a couple recordings of the sounds I'm experiencing. They seem to be getting worse. I moved from the US to Spain a while back so trying to get the piano serviced is a challenge and when you get down to it the PX-350 is not a high end unit and may not justify the expense of repairs. Since this sounds like an AC hum I replaced the power supply but doing so had no effect. I tried resetting the piano but likewise it had no effect. I have an oscilloscope but my electronics skills are at the Arduino and basic circuits level. I've attached videos demonstrating the problem. At this point I'm trying to decide if this can be fixed or if I should just buy a new keyboard (and if so, what). Perhaps if I do I can use the PX-350 as a Midi device.

Hi, I've had a PX-350M for a number of years. It's started producing an occasional loud AC hum when I'm hitting several keys simultaneously in the lower register and seems to be more likely to do it when the sustain pedal is pressed. I replaced the power supply but that had no effect. I moved to Spain a while back and don't have any repair shops nearby but I do have an oscilloscope and some rudimentary electronics knowledge. Is it possible to obtain a schematic or service manual for this piano? Thanks, Eric
