Screen Replacement Does't work

Hey! So I bought a new Ipod 5 32GB screen and I replaced it today. I brought up a video on youtube from iCracked and followed it exactly! But, now my screen will not turn on. I know that power is still going to it because when I plug it in to charge, it still makes the charging noise, Voice over works when i hit the home button, but the screen will not turn on no matter what I do. I disconnected and reconnected the connectors, and nothing, even my old cracked screen will not turn on anymore... any ideas
