If you’ve landed on this page, chances are you are staring at a faulty Wannien 101V0 power supply. Whether it’s a dead LCD monitor, a non-responsive CCTV power box, or an industrial display unit, the Wannien 101V0 is a common yet elusive piece of hardware. The golden ticket to repairing it is, of course, the Wannien 101V0 power supply schematic. And you want it for free.
2. Open Startup Resistors
One or two 120k-150k ohm resistors in series from the main DC bus to the PWM IC’s VCC pin often go open circuit. With the schematic, you can quickly locate and test them. wannien 101v0 power supply schematic free
Good for finding the datasheets of the specific ICs (PWM controllers) used on the board, which usually include a "typical application circuit" that is 90% identical to the actual board. Wan Nien 101V0 Power Supply Schematic - Expert Q&A The Ultimate Guide to the Wannien 101V0 Power
2. Dead Set (No Standby Light)
- Check the Fuse: If the black fuse is open (infinite resistance), do not replace it yet.
- Check the Switching MOSFET: The large transistor attached to a heatsink near the transformer. If the legs read 0 ohms to ground, it is shorted.
- Check the PWM IC: Often, when the MOSFET shorts, it takes out the PWM driver IC and a current-sensing resistor (a low-ohm resistor, e.g., 0.33 ohms or 1.5 ohms, usually marked R15 or R22).
