EOS70d- Can you Help? Black viewfinder screen. No shutter actuation.. No takey pics...

I handed my 70d over to my sister to take a shot and when she took it from me an error message flashed and it pretty much quit working. I'm hoping she just pressed some menu item or button by mistake! The msg flashed so quick there was no time to make note what it said. I was given back a camera with a black screen on the back; so now I can't navigate through any menus to find out what happened. There is also no shutter actuation when shutter button is pressed. I've changed out lenses. I've charged battery. Nothing. However, on the top nav window I can see I have a full battery, and can nav thru all the settings available, in both video and camera mode. So, I at least know the camera is alive to some extent. I've searched but cant find any subject covering this. Any ideas?? Here's a few photos of said camera. Also, dont know if my mirror is locked...could that make my camera behave like this? Thanks for any help. I miss my baby.

ok. I will give the hdmi a try. that might explain the back screen and allow me to access menu....but any ideas why the shutter doesnt work? Weird that two major items would quit at the exact same time. hmmm......

I think the only way to diagnose the problem is to send the camera to Canon. If you decide not to repair due to cost, you may ask them to send it back.

yea. im keeping that as a last resort option. not real confident tho....those repair costs are so high its almost best to just buy another body.

You're going to have to hypnotize your sister so she can remember what switch she flipped when you handed her the camera.

My guess is that it was the "On" switch that did it. The 70D is known to have a component on its circuit board that is to prone to failure when the camera overheats. Such failures commonly manifest themselves the next time power is applied, because suddenly applying power is one of the most stressful actions that an electronic component has to endure. If the component was weakened by overheating, it's likely to fail the next time the camera is turned on.

Thanks for the chime in, but i hadnt turned it off when i handed it to her. Does that problem totally kill the camera? I can still see the settings on the top lcd.... just the rest of the camera is paralyzed.

You sure the camera is not in video mode ?
