Joe, thanks for the reply.  I opened it up and found the problem.  A couple of the solder joints connecting the volume knob pot to its PCB were loose.  A little solder iron work and everything is back to normal.  The old PX320 is as good as new!

Hello,

I have a PX-320 and the internal tone generator is not producing any sound through the left channel.  Nothing comes out of the left channel through the headphones, line-out, or the built-in speaker.  The right channel is fine.  The problem only happens with sounds from the tone generator (playing the keyboard, metronome, demo songs, etc...).

If I plug an external device into the line-in, it comes through the left channel just fine.

I tried a factory reset by holding down the "Function" and "Rhythm" buttons while turning the power on, but that didn't fix anything.

Any suggestions would be appreciated.

thanks,
