Problem when switch between live view shooting and quick control screen

[Spooky2308]

I bought a Canon 700D T5i 3 months ago, it's worked well so far but suddenly somehow when I switched the camera from live view screen to quick control creen, it returned in black instead of showing information like it did before. Only when I press the Q button, it shows up again. Another problem is the camera did not show the review image after taking. Anybody have the same trouble, pls help me with.

There are various settings in the camera that can affect LCD behavior.  For example, you can turn off the momentary preview on the LCD of every shot that you take. 

When you are "LiveView", you really should exit LiveView mode before pushing "Q" for the quick control screen.
