Charger Has No Power
When a wall-mounted charger shows no lights at all, the first question is whether the unit is receiving power. A tripped breaker is a common culprit, and a problem in the circuit or wiring behind the charger can cut power off entirely. In some cases the charger hardware itself has failed. An electrical service provider can check whether power is reaching the circuit and whether the breaker, wiring or connection is the source of the outage.
