YOU OBVIOUSLY DON'T KNOW HOW TO USE IT OR YOU WOULDN'T BE ON THIS FORUM ASKING WHY YOU CAN'T SEE PICTURES ON THE SCREEN.
TWO THINGS TO DO:
1. If new read the book you got with camera.
2. Take it back it may be a faulty screen.
3. If you bought in from some person in street you've bought a crap camera.
My digital stills camera has a menu list which allows me to turn off the screen and onl view through viewfinder that is to save on battery power. So either it has that feature or as above in 2 screen is faulty.
