    Hi,

    I dropped my iPhone 3GS and my lcd screen was broken. I ordered a LCD screen + digitizer + home button + earpiece and flexcable assembly (with frame) from ebay and installed it. I have done this a couple of times, so I know how to do this.
    But I have a problem: when i press the home button/power button, only the backlight of the screen turns on, but I does not see anything.

    I also tried to restore my firmware (iTunes recognizes the iPhone perfectly), but that didn't work. I also searched google, but I could not found anything like my problem.
    My question offcourse: how to fix this? Is this a problem of the logicboard, or is the lcd screen not good?

    Thanks for your help.

    By backlight do you mean a blank white screen?

    No, I mean from black (backlight off) to grey (backlight on).

    I am not quite sure but I do recall from some video in youtube about assembling a new Screen when its shattered,that if you by mistake forget or misconnect any of the connectors of the digitalizers then you will get grey screen or no display at all. I know you are expert and everything but mistakes do happen with experts too right? The other possibility is your digitalizer and LCD is corrupted or damaged.

    Thanks
