Possible Causes

Blown internal fuse on PCB, Failed external power adapter (for low-voltage models), Faulty power switch or loose mains cord connection

How to Fix / Troubleshooting

Safety: Unplug from mains before opening. Mains voltage can be lethal.

Basic checks:

  • Verify outlet: Test the wall socket with another device.
  • Check external adapter: For models with a separate adapter, inspect the cable for damage and test the adapter output with a multimeter. Replace if no output.
  • Inspect power cord: For mains-powered units, check the cord and plug for cuts or kinks.

Internal checks (advanced):

  • Open base: Remove the bottom cover to access the PCB.
  • Check fuse: Locate the small glass or ceramic fuse on the board. If visibly blown, replace with the same type and rating.
  • Look for damage: Inspect for burnt components or tracks. Significant damage indicates the board should be replaced, not repaired at home.

If a new fuse blows immediately or you are not experienced with mains electronics, stop and contact a professional technician.
