Errot 99 Error 99 flashes when I click. I have changed the main battery and the small lithium battery but the problem still persists. What must I do?

Battery is shot and the 99% is a false reading. Send it in for repair.

take out the small battery lithium from +3vdc and measure it, it is lower replace, and clean the contacts, control the RAM, for many different opeation. and try again.
If the problem persist you have problem with the power supply, replace it.
God bless you

restart the computer and HOLD the CTRL or FN +f11 or f12 depend of your mark, go to restore factory default and ready
However if the problem persist, take out the small battery lithium inside measure the voltage +3vdc, if the voltage is lower replace, and clean the contact, and put the battery again, and restart and see what happen all data must be restore,since the battery control the memory RAM.
If the problem persist you have a board video/lcd faulty. go to the repair shop for fix it.
God bless you

Most of the lens issues due to mechanical problem. some of the causes are dropping the camera.
Hard shake like keeping the Camera in the hand while jumping through steps, Moisture condensation, Insufficient battery.. etc If If you feel that the issue is not with the above reason, try initializing the Camera. To initialize the Camera, please use the Initialize option under the setup 1 or Main Settings 1 Menu.
If the issue persists, perform a power reset of the Camera.
Performing a manual power reset Turn off the camera. Remove the battery pack. Remove the button-sized lithium battery. Allow the camera to remain without power for 30 seconds. Reinsert the button-sized lithium battery. Reinsert the battery pack. Turn on the camera. If the issue persist, service is required.

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

Thanks for using FixYa

error 99 means flash is stuck . pop the flash and when it clicks, you have to smack the side of the camera to make it pop open

The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

Hi there.
That's the battery that keeps the time and date and is located inside the camera itself or is in a hidden compartment.
As soon as you change the internal battery the error message will disappear.

Good luck and thanks for using FixYa!!
