"Err99" code in Canon display screen

by revbochuk / August 10, 2011 12:25 AM PDT

HELP!! I have a three year old Canon EOS Rebel XTi. Recently I tried to take a photo, and after snapping the shot was greeted with a message in the display screen that read: "Err99" The instructions said to "Turn the power switch off and on, and/or reinstall the battery." I have done this repeatedly with no change in my ability to take photos. What is going on, since I waited so long to purchase an upscale digital 35mm camera and now have this problem. Is this a common problem with this model of camera? I called a camera store in OKC and was told they could fix it but it would cost about $250. This is ridiculous!! I thought Canon sold a good quality product. I am thinking I should stayed with my Minolta SRT101. Please help as I'm going on a trip the first week of September and wanted to take the Canon with me (along with my Nikon Cool-Pix).
Thank you, Charles Baumann

New Battery

I would try installing a new battery to see if that solves the problem. If it does not, then you will know the problem lies with the camera.

Thanks for the advise, but I have already done this -- with no success.

Thank you for your suggestion. The batteries I have are both fully charged, but are not brand new. How long should these batteries last? Thank you also for the link to instructions for a reset. Unfortunately after trying this twice I still get the "Err99" code and am unable to take photos.

Rechargeables get about 300 cycles then are suspect.

While we often get more, figure 18 months if we use them a lot.

Canon uses the same error codes for all their DSLR cameras.
Canon uses that code as a catch-all.
If something happens that the camera can not diagnose, it reports Err99.

It can be something transient or associated with bad connections of many types.

Try another lens and see if you continue to get the Err99.
Do the same for memory card and battery.

Clean the contacts on the lens and body.

Some people report that they had to have the shutter mechanism replaced.

If you are unable to clear the error then you should call Canon Service.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
