My first guess is that a cable on your new display is unreliable: As the cable flexes when you close up your iPhone, one or more conductors in the cable are losing their connection. * If evidence shows that there is an iffy conductor, I'd remove and reattach the display, in hope that it's simply a poorly seated connector. * To determine if it the simple case that the display is simply not displaying anything, I'd try using a USB cable and see if the device shows up in iTunes even with a non-functional display. * If the old working-but-cracked display is still available and viable, I would temporarily re-install it and see if the old screen's behavior is normal.
