live view disappears after I push button down halfway on canon EOS R6

[barbstitzer]

Hi, I sent my Canon EOS R6  in to be cleaned and when I got it back, every time I went to take a picture and push half way down on the button, the model would show up for one second and then disappeared from view, both through the viewfinder and on the screen on the camera. I sent it back in and it happened again today. I have dozens of shoots next week because I didn't have a camera last week. Please, can anyone help me?

Or do you suggest anything else?

Is ExpSIM enabled?

Studio lights?  That’s news.

I suggest re-entering your settings bit by bit.  Hold off on using the strobes/trigger until last.  Tell us about your strobes/trigger setup.  

Is this a new problem?  Did the strobes ever work properly?

The strobes had never been a problem. They worked just fine the entire shoot… I just couldn’t see what I was photographing at all. I really didn’t configure my settings much, except to turn the beep off and make is so that I can’t shoot without a card
