Finding a free schematic for the Wan Nien 101V0 (often stylized as 101VO) power supply can be challenging because it is typically found inside specific LCD monitor models rather than as a standalone retail unit. These boards generally integrate both the main power supply and the backlight inverter on a single PCB. Core Components & Layout
Based on technical documentation for similar boards in this series, the typically includes the following stages: Power Supply Components: Parts, Functions & Availability
Finding a free, high-resolution schematic for specific hardware like the Wan Nien 101V0 (often associated with model E88653) can be challenging because these diagrams are frequently proprietary or internal engineering documents. However, understanding the core architecture of this power supply board is essential for repairing issues like "no power" or "no display" in devices like LCD monitors.

The Wannien 101V0 is a Power Supply Unit (PSU) board commonly found in monitors and industrial equipment. It is typically a Switch-Mode Power Supply (SMPS), which uses high-frequency switching to convert voltage efficiently.
Key Components: The board generally includes a transformer, rectifiers, filters, and voltage regulators.
Safety Standards: The "101V0" and "94V-0" markings often refer to UL flammability ratings for the PCB material rather than the circuit design itself.
Typical Outputs: These boards often provide stabilized DC voltages such as , or sometimes for backlight inverters. Where to Find Schematic Diagrams
If you cannot find a direct PDF download, these platforms often host community-uploaded or archived service manuals: Finding a free schematic for the Wannien 101v0
Since you cannot download a single PDF called "Wannien 101v0 Schematic," here is how to acquire the functional schematic for free.
This is the holy grail for power supply schematics. Search for "Wannien 101V0" or "101V0."
Note: I could not verify an exact product named “Wannien 101V0”; I’ll assume you mean a small PCB/system using a 5–12 V DC input (common for hobby boards). Below is a general, safe, and practical power‑supply schematic and explanation you can adapt for a small electronics board labeled “101V0.” Treat this as a template — verify component ratings and pinouts against your actual board.
Before diving into the technical details, it is important to address the request for a "free schematic."
The Wannian (万年) brand is typically a Chinese OEM (Original Equipment Manufacturer) that produces budget electronics, often rebranded or sold as generic LED TV mainboards. Unlike major brands (Samsung, Sony, LG), these manufacturers do not publicly release service manuals. Finding a 100% accurate, factory-issued schematic diagram for free on the internet for a specific revision like "101V0" is highly unlikely. Disclaimer: This post is for educational purposes
However, you do not need a specific factory schematic to repair this board. These power supplies are built using standard topologies. If you understand the generic "LED TV Power Supply Architecture," you can read the board without a diagram.
If you have raw DC (high voltage) before the transistor, but zero regulated output, the LM723 may be dead.
Some old electronics repair websites from the 2000s have closed down, but their schematic PDFs live on at archive.org. Try searching: "Wannien 101V0" filetype:pdf.
The Wannien 101v0 is suspiciously similar to the Tenma 72-860 and various generic "Mastech" or "Zhaoxin" models.
If you cannot find a schematic for "Wannien," search for "Tenma 72-860 schematic" or "Zhaoxin PS-305D schematic". You will likely find that the transformer pinouts, voltage regulation chips, and capacitor placements are identical.
