This video will showcase several different motherboard repair skills. First I identify that there is a short on the motherboard, causing no power. I measure the most common lines first (main and boost) to find they are not the culprit. I split the motherboard interposer (sandwich) to expose all the components and determine the PMIC is the cause of the amp draw before prompt to boot (the problem). This is seen with the help of freeze spray and voltage injection.

The PMIC removal is done with great technique. If you struggle with underfilled chips, pay close attention that part.

I had no replacement PMIC's in stock, so you will also see how I harvest a donor iPhone 13 Pro PMIC from a donor motherboard and reball it. This requires careful work. The PMIC is very delicate so it is quite difficult to pull and clean it without damaging it.
