backlight not working after replacing the screen?

Just replaced the entire screen and when I turn it on it appears the backlight isn't working, so what could have caused this problem? I have tried a hard reset and restore but those haven't made any difference.

Answered! View the answer I have this problem too

Is this a good question?

also to add: sprayed the iphone with an air duster on its contacts and the backlight seems to be working! I can't get bypass the passcode (bought it 2nd hand) so I can't restore it or change brightness settings

Put the phone in DFU mode and then do the software update. Warning: it would clear everything that you may have on the phone prior to update.

the old screen was cracked and didn't show anything, that's why I replaced it (sorry should have mentioned that)
