Dimmer lamp 1

Likely causes and remedy:

  1. The charger has failed, try a different, identical, charger (extreme care – the details on both chargers AND the connectors must match exactly
  2. A simple, repairable internal fault has occurred, open it up for a look.
  3. An internal component has failed or burnt out –unlikely to be economically repaired
