  MOSFETs: Look for the switching transistors (often TO-220 or surface-mount packages) which are the most common points of failure.

  | Symptom | Likely Cause | Schematic Clue | |--------|-------------|----------------| | No power, fuse blown | Shorted MOSFET or bridge rectifier | Check primary side components between AC input and MOSFET drain | | Pulsing output (clicking sound) | VCC voltage unstable (startup cap failing) | Locate electrolytic capacitor on VCC pin (usually 10–47µF) | | Output voltage low | Feedback divider resistors drifted | Search for resistors connected to TL431 cathode | | Shuts down under load | Current sense resistor open or CS pin noise | Find resistor (0.1–0.5Ω) from MOSFET source to GND | | BM5291 hot but no output | IC dead or missing VCC | Trace from auxiliary winding of transformer to VCC diode |

  Challenges include high costs for testing equipment and the risk of errors leading to unsafe designs (e.g., thermal runaway in BMS).
