1. Pre-Intervention Electrical Safety Protocols
  • !High-Voltage Safety Protocol: Disconnect 230V power before unplugging edge connectors or removing PCB.
  • !High Voltage DC Warning: Wait at least 5 minutes for SMPS and inverter filter capacitors (up to 380V DC) to discharge safely.
  • !Electrostatic Discharge (ESD): Ground yourself to the metal chassis or wear an antistatic wrist strap before touching circuit tracks.
3. Preliminary Mechanical & Visual Checks
  • Inspect PCB tracks with a magnifying glass for blown triacs, darkened copper tracks, or cold solder joints on power relays.
  • Check electrolytic capacitors for bulging tops or leaked electrolyte residue around pins.
  • Verify edge connector locking clips are intact and pins are free of vibration fretting corrosion.
