How to Fix / Troubleshooting

Ensure safety by unplugging before opening panels.

  • Check outlet and breaker: Test the wall outlet with another device and reset any tripped breakers or GFCI outlets.
  • Inspect power cord: Look for visible damage. If the cord is cut or burned, it must be replaced.
  • Access main PCB: Remove the rear lower cover. Look for an inline fuse or board-mounted fuse. Test continuity with a multimeter and replace with the same rating if blown.
  • Inspect PCB: Check for burnt components or bulging capacitors in the power supply area.

If replacing a fuse results in immediate failure again, or if the PCB shows damage, the main control board should be replaced by a professional.
