The AC voltage from the main transformer is rectified by a series of output rectifiers. Schottky diodes are commonly used here due to their high efficiency. Test each one with your multimeter for shorts or opens. wannien 101v0 power supply schematic exclusive
If the primary side is restored but the board still doesn't output the correct voltage, the issue lies in the secondary side. This section is easier to work with as it's at a much lower, safer voltage. ), these boards are widely available on the
The voltage ripple on the output is filtered by a set of low-impedance capacitors . Over time, these can degrade, leading to high ripple, poor voltage regulation, and system instability. Replacing them is a common and effective repair. If the primary side is restored but the
The “exclusive” Wannien 101V0 schematic is not publicly available. Your best path is to identify the main control IC and use its reference design as a reliable substitute.
