The LCD malfunction after digitizer replacement

Cracked my digitizer weeks ago, and ordered a new one. After replaced the crack one and connected the LCD to the motherboard, I found that the LCD does not work anymore. It can be turned on but looked like a damaged LCD. The pic is attached. I suspect that I damaged the LCD accidentally during the replacement. Also, the computer is not able to recognize the ipad when I connected it to my laptop. Guys, is there any chance that I could get this fixed and work?

Any help appreciated
