You can try leaving it on the charger for a few hours to see if it turns on itself. Sometimes your battery will drain during a repair and it can take awhile to get it back up and running on a normal level. The other possibility is that you got a bad charge port. This happens, especially when ordering parts online or wholesale. I typically expect faults in about 1 out of 20 parts. You may need to return it to the seller for a new one.
