The most direct and promising action is to contact user "pronet" on Badcaps. While you wait for a response, use the search tips and basic troubleshooting steps outlined in this article. With persistence and a little community help, you'll have that power supply working again.
What are you currently seeing on the board? Are any components visibly burned or damaged ?
Provides stable DC voltages (often +5V and +12V) to the monitor's main logic board. Inverter Section: wannien 101v0 power supply schematic free
The Wannien 101V0 is a Power Supply Unit (PSU) board commonly found in monitors and industrial equipment. It is typically a , which uses high-frequency switching to convert voltage efficiently.
Even without a schematic, a systematic, component-level approach can often identify the faulty part. Here is a step-by-step guide. The most direct and promising action is to
A sacrificial component (typically 2A to 3.15A, slow-blow) that opens if a short circuit occurs.
The Wannien 101V0 is a standard switched-mode power supply (SMPS). It converts high-voltage alternating current (AC) from a wall outlet into stable, low-voltage direct current (DC) required by sensitive digital logic circuits. The board is divided into two distinct regions separated by an isolation barrier: the primary (hot) side and the secondary (cold) side. 1. AC Input and EMI Filtering (Hot Side) What are you currently seeing on the board

When replacing filtered output capacitors, always select high-quality components rated for high-frequency operations and 105°C temperatures. Standard capacitors will overheat rapidly under high ripple currents.
