        Unfortunately, the value of r120 is unclear

          Just remove and check its resistance then. What is wrong with R123?

            That circuit migt be very similar to this one, If it is... R120 would be 10K

              The 10k resistor was wrong

                How did you figure out that 10K is wrong value? That is the typical value used between Gate and Source pin of the MOSFET.
