Wannien 101v0 Power Supply Schematic Verified [2021]

OUTPUT STAGE: +V_Raw → Collector of Q1 (2N3055) Base of Q1 → Series Resistor (100Ω) → Driver from Control Board Emitter of Q1 → Output Positive Terminal

: If the monitor has power but no backlight, the high-voltage transformers on this board are the primary suspects. Voltage Regulators

When a display using the 101V0 board fails to power on, a systematic diagnostic approach is the standard alternative to having a full manufacturer schematic. wannien 101v0 power supply schematic verified

Absorbs high-voltage transient spikes from the main AC line.

Suppress differential and common-mode electromagnetic interference (EMI). OUTPUT STAGE: +V_Raw → Collector of Q1 (2N3055)

Because these boards generate significant heat during transformer scaling and regulation, inspect the underside of the PCB for fractured or dull solder joints around high-heat components like the transformer pins and power transistors.

Look for bulging or leaking electrolytic capacitors, which are notorious for causing voltage instability. Inverter Failure: Inverter Failure: A verified schematic splits this board

A verified schematic splits this board into four core functional stages:
