Problem description
MacBook A1706 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
