Why is my nikon d3000 screen not working?

Added (1). I'm not an idiot, I know that this model does not allow you to view what the lens is seeing from the LCD screen before I take the picture. The problem I'm having is that the screen does not show anything at all-- the menu or the pictures that I have already taken after I summon the "play" function. Does anyone have any USEFUL non-condescending advice?

It has an off mode. Try turning it on. If it never works, contact Nikon to start the repair process.

If you are wondering why it does not display the scene you are planning to photograph, that is because it never does. DSLR's only do that when switched to live view mode, and this model does not have a live view mode.

Ehh… Because you have no clue whatsoever what you're doing.
