Double check if the viewfinder is operable (not the LDC but the little thing you look through with one eye above it). Try pressing the display button to flip through the different modes as you're looking through the viewfinder. If the viewfinder does work (and the LCD screen doesn't come on as you're scrolling through the modes) then it is most likely dead (broken). If the viewfinder works, you're can still use the camera otherwise it's probably time to get a new one.
