MacBook Pro A1707 Not turning on, pulling no current at 5V repair

Problem description
MacBook A1707 not powering on, drawing no power and the USB-C charger is stuck at 5V, this is most likely caused by a short on PP3V3_G3H.

Symptoms

 * Not turning on
 * Not charging
 * Zero power draw at 5V as measured by a USB-C meter.

Solution
PP3V3_G3H is most likely shorted to ground with a 0–1 Ω short, most likely due to bad capacitor. When PP3V3_G3H is directly shorted to ground, it won't produce heat—the PP3V3_G3H power IC is usually smart enough to just turn off when it detects a straight 0 Ω short.

You'll need to identify and replace the shorted component. How to find short circuits
