Wannien 101v0 Power Supply Schematic Repack Jun 2026

Before touching a soldering iron, take high-quality images of both sides of the board (the top components side and the bottom solder side). Compare your board with online images from other repair logs. If a resistor burns up, you have a photo of what it used to look like.

: This power supply has a non-isolated primary side with hazardous voltages. Do not probe unless you are experienced with live SMPS troubleshooting.

This is the most common complaint. The board receives AC power but outputs 0V DC. Repairs often involve checking the primary side components first. Technicians have reported that replacing the T3.15A fuse , the bridge rectifier , and the 0.33µF X2 capacitor often restores function to the primary side. wannien 101v0 power supply schematic repack

A "repack" in this context usually means replacing all essential capacitors and testing the main transistor switches. Tools Needed Soldering iron (30-60W) Desoldering pump or wick Multimeter Replacement Electrolytic Capacitors (105°C rated) Replacement Power Transistors (if needed) Step 1: Physical Inspection Open the device and inspect the board for signs of failure: Bulging or leaking capacitors. Burn marks near the transistors or resistors. Dry/cold solder joints. Step 2: Component Replacement (The "Repack")

Before altering any internal electronics, verify you are working with the correct hardware platform. Before touching a soldering iron, take high-quality images

In monitor versions, these high-voltage coils can develop internal shorts.

: Look for burnt resistors, leaking electrolyte, or cold solder joints. : This power supply has a non-isolated primary

Raw 12-15V DC arrives at the board. Initial capacitors filter out noise.

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