4. Critical Component Values & Repair Notes

If you are attempting to repair a "Wannien 101V0" board, pay close attention to these common failure points: wannien 101v0 power supply schematic exclusive

Scenario A: No Output, Fuse Intact

1. Measure C2 (Bulk Capacitor). Should read ~330V DC (for 230V input). If 0V, trace back to the NTC thermistor (TH1).
2. Check R2 (Start-up resistor). 220k ohms? If infinite, replace it.
3. Probe IC1 Pin 12. Needs 12V+ to start. If stuck at 8V, the auxiliary winding or C22 is failing.
