LXI TV-menu options keep scrolling. How do we stop...

Question

My neice wanted to watch tv and helped herself to pushing an array of buttons and now the tv keeps scrolling a menu of options/features. (This menu is almost like a "TEST" would be when you get a printer, and push a button and it prints out the features.. make sense)??

Is there any combinations of keys we can push, to get this menu to stop scrolling down the tv? please??
