Brand new iPhone 5c screen not working
I got a blue iPhone 5c right... I dropped it, my screen broke so I bought a new iPhone 5c screen replacement off amazon from china. I take the old screen off, unplugged the 3 plugs connecting the screen to the phone(the digitizer and other ones). I put the other screen on that I just bought and I noticed there was only 2 plugs that connected the screen to the phone(missing the plug closest to the side of the iphone 5c) but I was guessing it wasn't going to make a difference cause it came with home button and front camera all put in the screen, I put the phone together it didn't work. I try doing all this home + power button thing and still nothing, I open it back up and make sure its all the way pugged in and I try again and still nothing, I plug the charger in and it will just vibrate on and off until I take it off the charger and it will still make sounds and overheat. How do I fix this?
