It's difficult to make a diagnosis from the distance. But I suppose that the
module is defective and has to be repaired. Maybe the module was connected
in the wrong way to the bus. Probably some of the integrated circuits have
to be replaced. For details please contact our A-190 specialist Matthias
Marass ( keyboards@... ).
