Wannien 101v0 Power: Supply Schematic Repack

The 101V0 is typically a multi-rail power supply designed to provide the necessary DC voltages for both the main logic board and the high-voltage inverter circuit. Primary Side:

Rapidly switches DC power to drive the high-frequency transformer. Schottky Diodes, Smoothing Capacitors

A proper typically includes:

As Jonah probed, the lamp light tilted shadows across the paper and revealed a second, smaller note clipped to the bottom: “If repack — retime TL431 and add 10R in series with output sense.” It was stapled, not part of the original CAD. Now it made sense: the regulator was marginally stable unless the compensation network was altered to account for changed ESR and stray inductance introduced during repack. The 101V0 is typically a multi-rail power supply

Limits inrush current when the bulk capacitors are uncharged. X-Capacitor (CX1): Attenuates differential-mode EMI.

Often caused by a blown main fuse or a shorted switching MOSFET. Now it made sense: the regulator was marginally
