Hope this helps.

Take a look at this.

power on to auto lens up and dowen

take the battery out and let the camera sit for an hour or two, take out the memory card, try to view photos on computer, if it does not work, you will have to format the card and start over. Some times when the format on the card is bad, the camera will not work properly. I have two cybershots myself.

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.

I found this solution in Yahoo Answers. go into the Setup Menu and find "Initialize". Select Initialize to reset the camera adjustments. Then try using the camera again.

Your Brother Killed the Battery so Your brother goes and buys you another, And this time use the appropriate charger routines as outlined in the manual

Check the manual- it may be in the menu or a separate button. When you are sure it is switched on put the camera to your ear and listen for the flash charging up[a High whistle sound] If it does not come on or the ready light does not show - then assume it has failed.
