I replaced the front screen digitizer assembly on an Verizon iPhone 4. All instructions followed as outlined. Upon trying to turn the iPhone on, I see the backlight but there is no image at all. I disassembled, and reassembled rechecking all connections, etc. same issue. I have tried to soft reset, hard reset. Does not resolve the issue. When I hook the iPhone up to my PC it is recognized without a problem. Still it continues to only light the backlight but no image is displayed. Is something not making contact or should I conclude a faulty screen/digitizer assembly? Or is there another suggestion for troubleshooting?
