It does not turn on, the opto, ic regulator of the supply, 36v zener was changed. According to the diagram, the two capacitors, I already get voltage in the secondary, in the +b it outputs 50v. The 3.3 plus 1.8 appears but the 12v does not appear. What I have noticed is that there is a voltage fluctuation between 11v-15v in the primary, if you could help me I would appreciate it. | The power IC was found, a 1k resistor, the opt, and a burnt zener. | ||
