It turns out that the piano began working perfectly after I took it to a local electronics repair person. It was unplugged from power for several days before he tried it, and when he did there were no problems. He left it powered on overnight and it still worked perfectly. As far as I can tell, it's back to normal.

I have a Privia PX-330 that starts out with what I'll call "medium volume" with volume turned up all the way. The same is true for the other jacks (line out, headphone). After a few minutes of being on the volume drops to almost nothing (you can hear it if the room is quiet). Any idea of what is causing this, and if it's repairable?
