If this is your first time with ramps and LCD2004, on my LCD2004 there is a contrast control on back that needs to be adjusted.

If you got the lcd and the ramp's lcd adapter separately there is a good chance the cables need to rotated 128 degrees. The issue is there are keys to stop you doing this.
