Hello, I have an iPhone 10 PCB having internal short ( shorts in many caps test it by multimeter, by connecting the board to power supply and without power on the board started consuming power 0.06 to 0.13 up and down between those values) there’s no sign for heat in the PCB .
how to find the faulty component since No signed of damage?

 

Welcome to AAC.

While there is a chance you will get help here, it is unlikely anyone will have enough experience with iPhone repair to help in any way but general troubleshooting. Without naming any particular one, there are forums and websites dedicate to iPhone repair. You are much more likely to get useful help in one of those places.

Not trying to discourage, it's just practical advice. For a specialized task, specialized sites are more helpful.

Good luck with your phone.
