Sounds like you have not made LCD connections proper. Make sure that you have properly connected the LCD cables to the logic board. Also where did you purchase the replacement LCD? I have received faulty screens. I would test a new battery and your old screen or a different screen to assure it is not a problem with the phone. Always disconnect the battery before disconnecting and reconnecting the LCD cables. You don't want to trip the backlight fuse.
