Hello everyone


I have a Korg X50 keyboard (bought in 2007), and it stops outputting audio, both main outputs and headphones. I have tried factory reset, and making sure the local control is on, but it's still not making any sound. It's working fine when I connect to sound/midi devices (it output midi signal) so I suspect the actual sound board is not working?

Does anyone know how to fix this please.

Thank you

Hi, I suspect the problem is the volume potentiometer. I had the same problem, and solved changing the potentiometer (lineal, 10 kohms, logaritmic) and no has more problems.

The potentiometer is this:
