Re: Errot 99

Hi Rexveg, there is a good solution in Fixya. You just have to clean the lenses with a pencil eraser. Here is the link to that thread: Good luck

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


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

Cannon Eos 400D Err 99?

Error 99 is a NONSPECIFIC error message. It is almost always associated with the LENS. I first got this error on my EOS 20D whei I tried to use an older Sigma zoom lens (7 years older than the camera). I don't use off-brand lenses with my Canons. Try removing the main battery first followed by the time & date battery which is hidden in the battery compartment beside the main battery. This will reset your camera. Good Luck!

Flash Not working

Sounds like the flash unit is not charging up, or the charge sense circuit is defective. Could be something as simple as a loose solder connection on the PCB. No simple way of fixing it without taking the camera appart and poking around with a DMM or oscilloscope.
