Canon 5d Mk III error 20

[Moze]

Today during a shoot I got error 20 on my canon 5d mk3, and form that moment camera is not responding, I have tried to remove battery, change the lens and sometimes it gives error 20, sometimes when I turn it on it is completely dead.
Anybody had a similar problem?
And if yes, is it repairable in a decent period of time or I will have to wait more than few days?

Call the excellent help staff at Canon's Virginia call center: 800-828-4040. Follow the prompts for "Technical Support" and say the model of your camera.

Good luck, and please report back what they say the cause of an error 20 might be.

Link to a discussion on the 5D II and error 20.  Not sure it applies but it sounds like error 20 is a standard Canon error.
