    Hello MacRumors forumers!

    I recently bough an iphone 4 with the front glass broken. I also bought a display and front glass to make the iphone like new. I managed to put the display and all the things worked out fine. But i forgot to put the protection sieve at the ear-speaker and had to tear it apart and reasamble again. After that the iphone is working but only the backlight lights up like the video shown down here:

    The problem is that no other display works... So I'm thinking is something from the motherboard!

    I have this same problem, if you all find a solution let me know.


    I changed the home button and the battery connector came un soildered so I got it connected back to the logic board but the backlight works but the screen doesn't. So I don't know if one of the connections that maybe powers the LCD is not making a good connection or what. I can't find any info on the internet.
