I think you got other problems here ;-{ It appears the connector has lost a few of the contacts! The posts look like the screws are still inside! Did you need to use a lot of force to get the screws out or did the heads just pop off? As the pictures are a bit blurry I can’t tell if the someone forced things and tried covering it up. The logic board also appears to have corrosion damage as well. The connector can be replaced, the posts can be saved with some TLC using a left hand drill and taking the time and care to take the logic board fully out and using an ultrasonic cleaner after getting the screw remnants out. Basically, this is going to take someone with the skills, tools and access to the needed parts to try to fix. If you think this is not possible given where you are then the only other option is to replace the logic board.
