iPhone 5c charging port on the logic board

I have been working in a repair shop for a good year or so, so i am certainly no stranger to the basics of iPhone repair. However i bought an iPhone 5c the other week and it has been working fine except the charging port was faulty, i.e was only charging on one side of the charger.. tried loads of different chargers to only find the same problem. I tried replacing the charging port, and the same thing happened. I tried replacing it again, and then it stopped working at all! i noticed when i put the flex cable onto the logic board, it did not make the confirming "click" when it goes in, and i also noticed it was not seated entirely straight and looked a bit bent. I tried forcing it down straight, and re-fitting the cable many times to ensure the fit was right however the phone will not work at all now. I am assuming this is because the phone went dead, and because the charging port wont work, it wont turn on. Is it possible i have damaged the charging port connector on the logic board? When i look under a magnifying glass it does not appear to be damaged, however i am unsure.

Any replies would be greatly appreciated

Cheers
