Hi,Kimani from Nairobi here.
Am having exactly the same problem with my sony cyber shot DSC-W30 digital camera(my flash wont work and E:91:01 keeps flickering).
I've tried refreshing the settings by initializing the setup again and again as per the owner's manual but nothing doing.Need i say i use it everyday for about a year now but this error code started showing in mid May.I now can't shoot photos in dark areas and at night with good results.Pls help.
E:91:01 is error code related to Flash Circuit abnormality. It requires qaulified technician to fix and such person would be available at nearest Sony repair shop.
