I pluged the battery before the screen.

So i changed the Taptic Engine on my iphone 6s and when i finished i wanted to test it so i plugged the screen and then i plugged the battery , it worked fine and then i wanted to get the screws back on , soo i unplugged the screen by accident and then i replugged it and then a saw a light comes form it :D </3 the phone is still working i can tell form the sound of the vibration and the charging sound , i suspect that the screen connector got shorted or the screen broke but i’m not sure i need help please.
