What Does A Short On The Motherboard Mean? Full Explanation. Dead iPhone XR

Short to ground? What does that mean? And how do I fix it?

In this video, we’ll show you how to:
✅How to diagnose a No Power device.
✅What does it mean when there's a short.
✅How to use a thermal camera to find a short.
✅How does a capacitor work.
✅How to inject voltage with a DC Power Supply
✅How to clear the short
✅Do I need to replace the shorted capacitor?
✅And more!

This iPhone XR doesn't turn on. It charges at 0.431A via USB. On a DC Power Supply, it draws about 0.700A via the battery connector. Usually that means there's a short on a main power rail, like VDD MAIN, VDD BOOST or sometimes SPKAMP.

In this case, it was a short on VDD BOOST.

Using a thermal camera, I was able to spot the shorted capacitor right away.

Watch the full video to get a full explanation on how this all works. Understanding this fundamental information will help you solve a large majority of No Power situations.

Just watched First of your videos - fantastic Jesse - exactly what I’ve been looking for. Just got some equipment ( no thermal camera yet☺️) delivered and plan to tackle iPad mini 4 WiFi chip repair/replacement 🤷‍♂️ - and your unique and simple explanation of ‘short’ and capacitors etc is very refreshing - just subscribed, and plan to binge a little on your vids - great job - so thank you all the way from Belfast, Ireland 🇮🇪
😊😊😊😊😊
