Wan Nien 101V0 is a power supply and inverter board commonly used in older LCD monitors, such as the Wan Nien 101V0 monitor

Troubleshooting: Use a multimeter to test for stable voltage input and check all connectors for corrosion. wannien 101v0 power supply schematic free

Step 3: Map the Secondary Side

• Follow the transformer’s secondary winding to a Schottky diode (e.g., SR360) and then to the output capacitor (1000-2200µF/16V or 25V).
• The output voltage is regulated via a TL431 and an optocoupler. The TL431’s reference pin connects to a voltage divider between the output and ground.

• Connect STATUS LED from each rail via appropriate resistor.
• Optional power-good output from regulators to an MCU reset supervisor.

Safety Rating: Frequently marked with 94V-0, indicating the PCB material meets standard UL flammability safety requirements. Wan Nien 101V0 is a power supply and
