Having hard time locating short on PP3V0_NAND


Hi guys,

I have an iPhone 6 was not turning on. After connecting to DCPS I noticed that PMIC heats up. I confirmed that PP3V0_NAND is shorted to ground and using alcohol method I confirmed that PMIC heats up first in that circuit. I removed PMIC expecting that I removed short to ground on PP3V0_NAND but it remained. When I inject voltage up to 3V none of the components heat up but my DCPS showscurrent consumptions. What is going on?

There are not many components on that line but visually they all seem to be OK and none of them produce heat.

My wild guess would be that via within PCB on that line got shorted and thatís why I could not locate it. What do you think?
