Canon 40D Error 99 now Error 01

[Az_GTi]

So I have a 40D playing up at the moment. Error 99's now it's doing Error 01 - which I know is a problem the lens, mount etc.

It's not reconising the lens at all as F stop still says 00 with any of my lenses connected. Cleaned contacts etc. Any suggestions?

This makes useful reading re fault codes... http://www.learn.usa.canon.com/resources/articles/2012/eos_error_msgs.shtml


You have tried various lenses, which would suggest the Camera is at fault, rather than a lens - you've cleaned the contacts already - on the camera body as well as the lens ?

Have you removed the small cell battery for a period of time ?

I presume the lenses work no problem at all with your 7D ?

cheers for reply. Yes cleaned all contacts. All lenses work on other bodies but not on this body so definitely a body problem. Removed the CR2032 battery overnight, still no change. May need to get hold a tiny screwdriver and get the thing apart :bang:
