I replaced everything on the screen the digitizer and display and still nothing im not sure if the battery is bad or what but Ive had it plugged in for a good hour and a half and I cant seem to get it to turn on
Does the screen even light up? If not, you didnt plug the cable in, or its damaged.
If the battery is dead and you connect the iphone 6S to a charger nothing is shown on the screen, you need a working battery to see any life on the screen.
