Iphone screen not working, please help!

[chiphaven]

I cracked my screen but it was still working before trying to fix it. After replacing the touch panel I tried to test the phone and it sensed my finger but all I got was a dimly lit screen and there was no color. After taking apart and reconnecting plugs 1,2, and 3 I tried it again and this time I got absolutely nothing. The phone is still on and when I call it still rings but I cannot slide to answer it. Any suggestions would be greatly appreciated.

Isn't there a ribbon there? Sure you didn't break it?
