settings display always stays on

I bought the camera used. When I turn it on the screen shows the settings for whichever mode I am in. I cannot get it back to where I can take a picture. I want to put it in Auto mode. The first time I tried to do that I was no longer able to see anything but the displays. The only time the set up options are not showing is when I am in video mode. How do I get it in Auto mode and get rid of the settings display so I can take pictures?
