Canon 6D will not focus or flash in "Live View" mode.

[Shadowcat]

My Canon 6D will not focus or flash in "Live View" mode.  I have a canon 430ex II  and a E-ttl flash connected with a sync cord for E-ttl function.  The camera does simulate shutter action, but no photo is taken.  How can I over-come this problem. 

Once in a while, after trying to take several photos it will start working, but usually not.

Hi Shadowcat!

Thanks for posting.

It sounds like the AF Method is set to Quick Mode.  When the camera is set for Live View Shooting, there are different AF Methods that can be set.  In Quick Mode, the camera uses its dedicated AF sensor to focus when you press the shutter button down halfway. 

The image on the LCD will be interrupted while the camera tries to focus because the shutter closes and the mirror drops back over the image sensor.  This may look as though the camera is taking a picture, but it is not, it is only focusing.  No flash is fired during this process either.  Continue to hold the shutter button halfway until focus is achieved, at which point the image will return to the LCD.  Then you can press the shutter button the rest of the way down to take the picture.  The flash will fire and an image will be recorded.
