How to fix missing filters & capacitors on logic board?
I recently replaced the screen and digitizer of my iPhone 4S. After reassembling the iPhone turned on and connected to the computer but the screen was black (Apple logo during restart but no backlight) so I took to a technician who took it apart and spotted the problem:
I tore off these components: C76, FL4, FL3 and C405.
I have a donor board with all of these components, but the technician told me that FL4 might be harder to resolder since the soldering point has also been torn and that he has to find where FL4 line on the logic board goes in order to solder a wire from FL4. Therefore I wanted to verify that the components I tore are the actually the ones I pointed out and if there’s any other way to successfully resolder the damaged components? Is the bridge the best solution for FL4?
