Wannien 101v0 Power Supply Schematic Fixed Free -

If you need to trace the board:

Usually, the primary switching MOSFET has suffered a thermal breakdown, shorting its Drain to Source pins. This passes raw high-voltage DC directly to ground, immediately vaporizing the main fuse. wannien 101v0 power supply schematic free

Since a "free" PDF schematic is rarely hosted on official sites, engineers typically troubleshoot based on the standard SMPS block diagram: If you need to trace the board: Usually,

Often integrated into a single multi-pin IC package (such as a Viper, Fairchild, or OnSemi variant) or split into a standalone Pulse Width Modulation (PWM) chip driving a discrete high-voltage MOSFET. This component rapidly switches the high-voltage DC on and off through the primary winding of the main transformer. The Secondary (Cold) Side wannien 101v0 power supply schematic free
