Ok well I replaced the LCD screen on an iPhone 3G and everything came on and worked except for the home button. So I reopened the phone to check if the number 3 cable had come loose. Once I closed everything up again I could not get the screen to turn on. Then after awhile the screen would come on, but it would just be white. However, now I cannot get the screen to display at all. The phone is recognized in iTunes, vibrates, and makes all the normal noises. The screen just won't come on. I have now tried restoring normally, restoring in DFU mode, disconnecting and reconnecting the logic board, removing the logic board and putting it back in, and doing the reset using the home and power buttons. I have also tried using the broken LCD screen to see if it would work and it won't either. I'm not sure what else to do.

hi, i have the same problem where the lcd is not working about removing it and then putting it back. have you found a solution. thanks. saquib

i have the same exact problem. ANYONE WITH a solution???

You may want to try posting to the hardware forum -- you'll likely get more people viewing it who have had similar issues than just posting in the 3G section... As you've checked the obvious (connectivity, etc) there's not much I can think of to tell you. I can't imagine you all got bad LCD/digitizers, but the hardware gurus will probably have a few more things to test.

got the exact same problem please someone help me
