Flash not working error sign E 91;01 on the lcd screen model dscw110

Hi,

The E:91:01 is the self diagnostic code display of the Camera which indicates the symptom of the issue. This can easily be identified with the help of a authorized service technician.
The E:91:01 code indicates the abnormality of the Camera when the Flash is being charged. Normally this can be resolved by some normal troubleshooting steps and if not changing the Flash unit.
Try recharging the battery in the Camera to Full and then power resetting the Camera. To power reset the Camera, remove the batteries from the Camera, press and hold the power button of the Camera for 30 seconds and then re-insert the battery pack after 1 minute. If the issue persists, try INITIALIZING the Camera. To Initialize, press HOME, select SETTINGS--> MAIN SETTINGS 1-->INITIALIZE-->OK
If the issue persists after resetting and initializing, service may be required to resolve the issue with the Flash unit
