Wont turn on, computer not recognizing, gets hot

Okay so I replaced my lcd screen back in April. A couple of weeks ago it started to get fuzzy so I thought a ribbon cable might have gotten loose. When I checked to see if all of the cables were connected, I accidentally put a longer screw where it shouldn't have gone...I know rookie mistake. Anyways the phone was still responsive to notifications and was able to be recognized by my Mac. I let it sit and I guess it eventually died on me. I plugged it into the charger and it gets super hot right near the front camera. Even though power is getting to it the computer won't recognize it anymore. Please help
