Just replaced the LCD/Digitizer on my iPhone4 the screen works fine. Then, it gets fuzzy after some time and then blacks out. Then I have to lock the screen, then unlock, the picture comes back to normal. The picture only lasts for about a few seconds before it gets fuzzy and blacks out and i have to repeat the process.


  1. Reset the phone
  2. Reseated the cables onto the logic board
  3. Readjusted that yellow tape on the LCD cable
  4. Cleaned the connections to make sure there was no dust

One thing to note: on the digitizer i got a few specs of dust on the mirrored side, does that matter? Will that cause the picture to be inconsistent? Help!
