Wannien 101v0 Power Supply Schematic Exclusive ~upd~

. Check continuity across the input fuse with a digital multimeter. If open, check the primary MOSFET for an internal short before replacing the fuse. Output Voltage Fluctuations (Clicking or ticking noises)

The 101V0 board follows a classic Flyback Converter topology. Based on trace analysis and component population, the signal flow is as follows: wannien 101v0 power supply schematic exclusive

The feedback loop has broken down, preventing the PWM IC from regulating correctly. What to check: wannien 101v0 power supply schematic exclusive
