| Designator | Value (Schematic) | Function | | :--- | :--- | :--- | | F801 | T3.15A/250V | AC input fuse | | R831 | 0.22Ω/2W | Current sense for main FET | | C822 | 100µF/450V | Bulk capacitor (smoothing after bridge) | | D902 | SB3100 | Schottky diode for 5V output | | R724 | 15Ω/1% | LED current sense (safety critical) |
Remember: always match the to your physical board. Use trusted sources like ElektroTanya or Badcaps forums, and respect safety rules when probing high-voltage primary sections (up to 400V DC). tpv56pb801 schematic diagram pdf upd
