Injecting voltage not producing the expected results, help please!
This applies to more than just the iPhone 7. When there is a short on a line I’ve learned that you connect a lead to ground and one to the line the short is on and apply voltage so I did. I have a Flir One Pro thermal camera to help spot the shorts but what is happening is the heat is always staring from where I am injecting the voltage, which is usually a test point on that line and spreads from there. I must be doing something wrong. This has happened on all devices that have shorts that are not on VCC. VCC shorts have been easy to find. Any suggestions, or video tutorials you can point me to would be appreciated.
