iPhone 4: Removing Metal Covers On Logic Board

Fri, 17 Aug 2012 21:30:46 -0700

Hi everyone. I am attempting to repair an iPhone that has water damage. It powers on and everything but the backlight doesn't work. I've read that the culprit could possibly be the backlight ic coil and I understand it to be under one of the metal shields. I was able to remove two shields from the logic board but I cant figure out how to remove the shield that covers the IC coil. I'm now assuming that this one is perhaps soldered to the board but I wanted to make sure before I attempted to remove it with a soldering iron. Thanks!

iPhone 4: How do I install my Backlight IC coil thing? Any tips?

Wed, 13 Mar 2013 15:24:26 -0700

I dropped my phone in water, and now my backlight doesn't work. I heard that I should replace the backlight on my phone, but even if I buy the backlight IC or coil thing, I don't know how to install it. Do I need to know how to solder? Or is there someone that I can be referred to that can install it for me for cheap? Thanks.
