Regulates output voltages (typically +5V and +12V/15V). Issues here often manifest as "pulsing" power caused by dried-out capacitors near heat-generating components like FETs. Inverter Section:
: Standard factory schematics for these boards are often difficult to find. A "proper" repack provides clear signal naming and component mapping, which is essential for diagnosing the "no power" or signal failure issues typical of these units. wannien 101v0 power supply schematic repack
