Hi guys. First post on this board. Okay. my problem is, that my Iphone 3GS i gone into white screen. I replaced the glass and digitizer and everything went fine, but not the power button, when i squeeze the phone it works. Then i took apart the phone to see if i did something wrong. (Everything worked) When i could not figure out what was wrong, i accidentally took a 3G! screen and tried to connect it. I wondered why i would not fit, and then i realized that it was the 3G screen. so i took it out, and then i used the 3GS screen agian. and when i assembled the phone it just went white. I tried resetting it (Power & Homebutton 10 sec.) Nothing works, i can hear the phone works. and the vibrate and everything works. But not the screen. Anybody has any suggestion why this is happening ?
