Learn Electronics Repair #062

In this video we look at VRM circuits. These are very common circuits, especially on Motherboards and Graphics Cards. In order to diagnose these devices we need to understand how the VRM works and how to find the faulty component(s) when they fail

This is an important fault finding tutorial - make sure to watch it and if anything is not clear then please post in the comments section below and I will help you because you really need to understand this one
