It is a super difficult source does not appear in any diagram even on the devices that use it. But, having the concept of how it works. The most important thing to know is that if there is no voltage of 17 and 24 then the IC of the primary is not oscillating or else, the mosfets are bad, and in the end it is necessary to verify the zener of reference and the opto.
