| Block | Purpose | Why You Need It | | :--- | :--- | :--- | | | Line filter inductors & X/Y caps | Diagnosing blown fuse or noise issues. | | Rectifier & Bulk | Bridge diodes & main cap | Measuring 300V DC input. | | PWM Controller | IC, timing resistors (Rt/Ct), VCC supply | No startup, no oscillation. | | Power MOSFET | Switching transistor & gate drive resistor | Short-circuit failures. | | Transformer | Pinout (primary to secondary) | Testing winding continuity. | | Output Rectifiers & Feedback | Diodes, caps, TL431, optocoupler | Regulation problems (over/under voltage). | | | PWM Controller | IC, timing resistors
If the part is an IC, look for a secondary manufacturer logo or code (e.g., TI, ON Semi, or ST) which might lead to a standard Datasheet .
can sometimes provide internal photos and block diagrams for devices with wireless capabilities. SERVICE MANUAL - iFixit
