Korg Wavestation A/D headphone problem

My Korg Wavestation A/D headphone out does not work
All the rest is fully functional.

I saw on the service manual there is a module KLM 895 wich provides the jack for headphone out and circuit.

I opened it up and can’t see any damage, no capacitors or stuff that seem to be faulty.

Maybe this klm895 board can be replaced?

Kind regards
