Well thought, but its analog in the beginning: The FB control is a
potentiometer with a DC value that is converted to digital. So if the
potentiometer or the parts arround it are not acurate enough, they dont
reach the voltage for the 1.000 value. Which part it is can be found with a
volt meter...
Sorry for this one!

could cause it, but probably you would note other problems like hum in the
