Iphone4 screen replacment

[micky345]

I replaced a new screen for the iphone 4 but i nipped one of the connecter cables putting it back together is this enough to stop it working, It will ring but I can't answer because the screen is blank. Any sugestions do I need another screen?

i would check and make sure it was installed correctly and all connections are in place securely....if still no display, then yes u most likely damaged connector making it no good. good luck.
