Industrial and display environments can trap moisture. Look at the main wire harness connectors. Clean away any green or white buildup with isopropyl alcohol to ensure clean contact. Wannien 101v0 Power Supply Schematic | PDF - Scribd wannien 101v0 power supply schematic

When analyzing the board or reading the schematic diagram, components are grouped into distinct functional sectors: Component Category General Schematic Designation Primary Role in the 101v0 Circuit Drops 12-15V raw input down to a smooth 5V logic rail. Switching Transistors Q1, Q2, Q3, Q4

If you want, I can:

The power supply was completely dead, with no output voltage. When connected to a 220V mains supply, the primary side of the board was receiving the correct high voltage after initial repairs, but the secondary side remained at 0V, indicating a fault in the primary-side switching circuit or the secondary-side regulation components . Treat the Wannien 101V0 as a useful, low‑cost
