IPhone 4 screen problem after re-assembly?

I had a replacement, but it broke. So i had to resort to the old one. The LCD came detached to the actual screen (that little thin*** wire connecting to the two that go to the motherboard). But, I taped it back. However, I'm still not getting anything. Any ideas? I'm just curious, if it's actually broken beyond repair at least I'd know what's wrong.

You are kidding me right tape.really its *** now if the lcd came out its *** secondly tape really now?

  • White Screen of Death on My IPhone 3GS After Replacing Screen? I recently replaced the cracked screen of my IPhone 3GS. After reassembling it, I got the White Screen of Death. I've tried holding the power button and the home button to try to reboot, but it does not work. The phone seems to still be working normally other than the screen. In fact, it is currently playing music. Does anyone have and suggestions on how to fix this?

  • What would happen if assembly line wasn't made? If Henry ford didn't invent the assembly line what would be happening today? Like how much would famous products cost be? Like iPhone, how much more would the price for iPhone be, or any other famous products? What would be cars prices? Would there be less cars? What would be the situations for employment would there be less people or more? How does assembly line help the daily life for all of us?
