Hi EveryBody. I have a question plz only for general knowledge because I m learning about smd board repairing. I have an iPhone 6 plus. If I check the voltage on c2414 it will be 5 volt right? My question is : the voltage wil be same with or without lcd connector attached? (obviously iPhone must be turn on :) ) I m asking because I have an iPhone 6 plus with no touch responding. I check the voltage on c2414 and it was ZERO. I reball u2402 and touch screen begin to function perfectly, but the voltage on c2414 is zero. So I m confuse, I m not understanding which is the way for understand where is the fault, before recall or changing ic’s. Thanks a lot for attention and forgive for bad English :)
Yes, you will have to have screen attached to see the PP5V7…Rail is referring to the particular circuit…The 5v you are looking for is on the PP5V7 rail, as seen in the picture I added…everything red is thePP5V7 rail, the other side of the capacitor is on ground. Here is a video that describes what you are asking as well…it starts at 3:30 into it but it is very helpful in Touch IC troubleshooting in the future.
