Won't turn on, power supply broken | 100pf ceramic capacitor connected between the drain and power supply of the mosfet, I prefer to place two 220pf in series, even if one of them shorts out, the power supply continues to operate well. | Other cis that can be used in this power supply is the ld7530, leaving only a 47nf capacitor between pin 3 and ground, or the ld7531, leaving only the 91k resistor between pin 3 and ground. | Davi.sls |
