Water Damage Fixed, but Rear Camera Not Functioning

Hey, I have an iPhone 4 32gb (CDMA - Verizon) that I just cleaned up for water damage (removed all corrosion with isopropyl alcohol). The phone boots up & work's near-flawlessly now, however the rear camera/Flashlight simply wont work.

I attempted switching in its place a new camera (in the same phone), but it still wouldn't work; leading me to assume that it may be one of the components on the board. Upon closer inspection in the logic board, I could see that the corrosion ate into the metal rear camera connector and its surrounding components - here's a picture:

Do any of you know which parts I'd need to fix this, or if the problem is even from the logic board? I personally am new to smd soldering and am buying Elenco's smd training equipment/guides, soldering supplies, and a smd magnifying glass. Do you guys think that's a good place to start, before diving into a repair like this? I'm open to any suggestions, thank you!

Answer this question I have this problem too

Is this a good question?

Most likely the problem is on the motherboard as you said, over the contacts of the camera has small components are related to the camera but before exchanging should check with the new camera could be that the contacts of the camera need to re-solder.

This correction level is difficult if you have no experience you will have a very difficult fix and most likely will cause damage to the motherboard, I would recommend that you go to lab or expert to handle it.

It may sound stupid, but are you sure you used an iPhone 4 camera? The iPhone 4/4S cameras look very similar. Also, make sure that you properly pressed the camera connector into place, as this can sometimes be tricky, and is the main cause of failed rear cameras after replacement. If it still doesn't work after that, I'm afraid that I am of no use ;)
