Removing Metal Covers On Logic Board

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!
