Let me know which would be most helpful for your project.
The Wannien 101V0 (often associated with model E88653) is a switching mode power supply board widely used in monitors and industrial equipment for its high efficiency and adjustable output capabilities. Core Circuit Architecture
The 101V0 schematic features a robust design optimized for regulating DC voltage and controlling multiple power outputs:
Primary Regulation Section: Steps down a 12–15V DC input to a highly regulated 5V output using a dedicated IC voltage regulator.
Transistor Switch Network: Includes four discrete transistor switch circuits (labeled out1 through out4). These are independently toggled by trigger circuits to manage specific power rails.
Signal Management: Uses a combination of resistors, capacitors, and integrated circuits to stabilize triggering signals and prevent voltage fluctuations. Technical Specifications Input Voltage Typically 12V–15V DC Adjustable Output Voltage range of 0V to 30V; current up to 5A Efficiency Rated up to 80%, minimizing energy waste Protection The Wannier 101v0 power supply features several protection
Built-in Over-Voltage (OVP), Over-Current (OCP), and Short-Circuit Protection (SCP) Troubleshooting & Maintenance
The schematic is an essential tool for repairing Wan Nien monitors when they exhibit "no power" or "no display" symptoms.
Common Failure Points: Faulty capacitors and blown fuses are the primary causes of board failure.
Testing Protocol: Use a multimeter to verify voltage input stability and check for corrosion on connectors.
Component Replacement: Detailed diagrams found on platforms like Scribd or through repair-focused Expert Q&A sites allow technicians to accurately identify and replace damaged resistors or transistors. Wan Nien 101V0 Power Supply Schematic - Expert Q&A

Unlike cheaper supplies, the Wannien 101v0 includes a MOV (Metal Oxide Varistor) located at RV1 on the schematic. This clamps voltage spikes. Directly behind it is a common-mode choke (L1) with a 20mH rating. Exclusive tip: If the supply is dead but the fuse is okay, check RV1 for a short circuit.
