Screen lights up but no picture, phone works but screen is black

Had a broken home button which I've just replaced today but after reassembly the phone appears to be dead when power button is pressed.

It will eventually start and the screen goes from being completely black to a lit up black when home or the power button is pressed, its recognized by iTunes and will sync so all seems to be working fine except the screen.

any ideas what the problem may be?

or have I broken the screen accidentally during repair

Answer this question I have this problem too

Is this a good question?

try holding the power and home button for 10 seconds to force your phone to restart. if that doesn't fix it then open the phone up again and check under the wifi antenna and make sure the data cable for the display is securely pressed down. if it is then you damaged the display and need to replace it.

Tried holding home and power, still no difference, will fully take apart and reassemble again and see if I have any luck.

Thanks for the reply

Sorry to be the one with the bad news Zeruel but your going to need a new front screen assembly, you either flexed your LCD while prying it from the mid frame and damaged it or damaged your LCD-Digitizer ribbon cables assembling it, its real easy to do, good luck.
