I have changed the power button cable to my Iphone5, then it keeps in restarting every 3~5 minutes, when I check the logic board I found it missed 3 part “resistors or capacitors”? I am not sure. attached photo for that area, and I need your help to identify which parts those are, and from where to buy?
Thanks in advance.
From left to right: C9, C279, FL11 C9 is just a ripple filter, you won’t die without it. C279 is a filter for battery management I/O FL 11 is an inductor for battery management I/O. Without it the system cannot read battery status so it keeps powering off as a safety measure.
Ramadan, this is strictly to augment Tom Chai’s answer. He is absolutely correct and I do just want to complete the answer to your question.
Reference designator C9 is a 56PF 16V 5% capacitor in a 01005 package Reference designator C279 is a 56PF 16V 5% capacitor in a 01005 package Reference designator FL11 is a 120OHM-210MA filter (TDK MMZ0402S121C) All parts should be available at places like Mouser.com or Digikey.com as well as many others.
