iPad mini touch won't work after replacement

Well, after the replacement done by myself touch won't work. The home button is working perfectly, the pins both on male and female side looks perfectly fine (images attached) and I tried hard reset, still nothing. Any clues what it could be? I bought the digitizer with the ic chip soldered, so I guess bad soldering shouldn't be an issue... Any clues?
