Canon PowerShot S400 Troubleshooting

The battery itself may be the problem. Remove the battery from the camera and insert it into the charger. If the light on the charger is red, the battery does not have a charge. Leave the battery in the charger until a green light is displayed, indicating the battery is fully charged. If the light does not transition from red to green, replace the old battery with a new one. If the charger indicates a charged battery and the camera still does not turn on, check the wiring or replace the battery.

If the charger indicates a charged battery but the camera still does not turn on, check the wiring and the contacts between the battery terminals and the camera.

The camera will not flash

If the camera will not flash replace the flash bulb.

If the camera still will not flash replace the capacitor.

Note: The capacitor carries a charge and can deliver an electric shock if handled improperly.
