So, I changed the proximity sensor on my iphone 4 (at&t) and it seemed to go well. However, once I got everything back into place I found that my screen was dim (back light only), very frustrating. Here are the symptoms:

  1. It seems everything is still working although I can not see the screen (i.e. can still make calls using voice commands, can hear incoming calls although can not accept since I can not control the screen)
  2. I’ve tested two other screens and neither of them worked. However, the two other screens flash bright white when activated.
  3. When replacing the power button bracket I found I had to leave the two screws unscrewed by about a full rotation to allow the power button to “click” I’ve tried a hard reset, no dice. I’m letting the battery fully drain as we speak. Any suggestions on what the problem may be? Thanks a lot for your help

Good (and bad news)! So, unfortunately after letting the battery die the screen did not miraculously come to life as I hoped it would. I thought for sure I fried my “6r8” coil (I dont really know what that is) and was preparing to take the phone in to get professionally worked on. However, just to be sure, I tried my old screen one.. last… time… VOILA! The hard reset/battery drain must have worked for them! So I must have been too rough on the cables when installing the power button and torn something.
