Hello everyone! I just assembled a friend’s display and after putting everything back together the display doesn’t display anything correctly. Here are some images: This one is supposed to show the Apple logo on startup. http://cl.ly/1E0Q0t0T3t262p0X1e0C This one is the lock screen: http://cl.ly/3M2c0i3G390t0F1R0N1p I really hope you guys can tell me what the problem is. I hope its not a faulty display! Thanks!

That looks to me like a faulty LCD. You will get them 1 in every 1000 or so. Anything that is powered by electricity has the possibility to be faulty, just a fact of life. I bought a brand new cannon handy cam for about $1000, and it just decided to turn on and off whenever it felt like it. Why? Who knows. Because the LCD is actually attached to the Digitiser itself, you will need to buy a new iPhone 4 Digitiser assembly (that is unless you have a heat gun and lots of patients to separate the LCD from the Digitiser) Show these pictures to the supplier you got the original Digitiser from and they should be able to refund you or send you a replacement. Hope this helps! :)
