Wannien 101v0 Power Supply Schematic Repack __hot__ May 2026
Title: Technical Analysis and Re-Packaging Guide: Wannien 101V0 Power Supply Board
The Wan Nien 101V0 (E88653-S) power supply board, often found in monitors, commonly fails due to faulty capacitors or blown fuses, requiring a +12V DC output for proper operation. Troubleshooting involves inspecting the 94V-0 rated board for damaged components, with schematic insights available through expert forums.

Step 6: Document Your Repack
Add your findings back to the community. This is the spirit of the “repack” – shared knowledge. High Resolution Photography: Take a photo of the
If you are working from a schematic repack, focus your multimeter testing on these high-probability failure areas: Visual Inspection often found in monitors
Common failure: The startup resistor opens, preventing the PWM from oscillating. Symptom: No output, but bulk capacitor holds 310V DC.
Construction: It utilizes standard 94V-0 fire-rated PCB material. Key sections include the EMI filter, a primary bridge rectifier, a high-voltage switching transistor, and an secondary output stage. Common Fault Analysis
- High Resolution Photography: Take a photo of the top side (components) and bottom side (traces) at 300 DPI.
- Trace Mirroring: Using GIMP or Photoshop, mirror the bottom layer so it aligns with the top.
- Chase the PWM IC: Start at Pin 1 of the controller. Identify VCC (usually goes to a small cap and a startup resistor from the 300V rail).
- Redraw in KiCad or EasyEDA: Manually place components and draw nets. This is time-consuming but yields a perfect repack.
- Share Back: Upload your repack to repositories like ElektroTanya or Badcaps.net under the name "Wannien 101v0 Rev X Schematic Repack."
