Long story short, I use my EOS Canon Rebel T6i as a webcam with the EOS Webcam Utility. Recently I took it down from it's mount to take pics but the LCD does not want to present itself.I then noticed that the LCD screen comes back when I plug the cam...
Those were my initial thoughts, however there's a loophole I guess? So yeah, camera on (not video) set to "P", no LCD picture and when I look through the viewfinder; if I hold down the capture button halfway I see a blinking "busy" for about a minute...
I've already inspected and made sure nothing was obstructing the viewfinder. It's just really strange to me that the screen works fine when plugged into the Mini USB but not when I disconnect it from that.
