How to find small shorts on iPhone circuit
i have an iphone 7 that wont turn on i believe there is a short somewhere on the board
but i can't find it as the short is small and i believe it's somewhere on data line
or maybe an IC is defected so when i connect phone to power supply the current is zero which means no short on pp_vdd_main but when i try to turn it on it stuck on 0.07 amp and stays there i did change the Tristar and Tigris but no luck so i come to conclusion that there maybe a small short i tried really hard to to find it but no luck would be great if you guys can help to locate this short that stop the phone from booting
just to let you know i dropped the voltage to run more current into board but only goes up to 0.10 amp which still doesn't help to locate the short
Is this a good question?
