Hi,

You can try to open it and re-connect the LCD flex cable, but I think that it is for replace.

:-(

Use this manual:

iPhone 4 (GSM/AT&T) Screen Replacement

but after disconnecting the battery go directly to step 13, 14 and in step 17 you will see the connector of the LCD and the digitizer. Reconnect both of them.

Regards
