• Fault cause:

  3. Charger internal malfunction.

  
  

  Troubleshooting:

  Frist, ensure the  power supply is working and voltage is normal.

  1. Check if the charger plug is loose, if so, reinsert it.

  2. If the plug is fine, inspect the charger input wire for damage. Repair or replace the wiring as needed.

  3. If both of the above are fine, the charger itself is faulty and needs replacement.
