Screen replacement with few issues.
Replaced screen and no display. It connects to itunes. Home button works as i can feel it. The vibration does not turn on when i press the switch down. Also the original screen does not work. Any ideas?

Disconnect all the flex cables from the motherboard and examine both ends with a magnifier for damage and debris. There are small soft gaskets around all of the plugs on the motherboard to help keep the phone water resistant, and if you aren't careful it's pretty easy to pinch that gasket between the conductors when you're plugging in the cables. This will disrupt the signal and can cause the screen to appear to not work.

I checked all connections. No obstructions.
