I'm trying to take a picture of but the pictures keep coming out blurry! The background of the pictures always come out...

When I turn the camera on, the LCD screen stays black no matter what I do. help!

The flash is actually an external component of the camera that is attached beneath the flap on the top of the camera. Your flash is most likely not attached properly.
