While specifications can vary based on the specific transformer winding used on the 101V0 platform, the standard configuration is as follows:

An optocoupler and TL431 shunt regulator that monitor the output voltage and signal the "hot" side to adjust. Common Faults & Maintenance

Official schematics for Wan Nien boards can be difficult to find. You can often find them in service manuals for the specific device it powers (e.g., specific HP or ViewSonic monitors) or via specialty electronics forums like for the capacitors or finding the specific monitor model this board belongs to?

: Over time, terminals for motor connections or power leads can develop corrosion, leading to unstable voltage input. Troubleshooting Steps
