I have a Motherboard with a short circuit in the VRM. It's easy enough to diagnose the fault but not so easy to find the actual shorted component. In this video we look at both theory and practical short circuit finding in a multiphase VRM. Learn how to diagnose this type of fault, then I look at five methods to locate the actual short. Only two of these methods worked and you may be very surprised to see what they were! Watch ALL OF this video and you will be able to locate VRM shorts like a pro! Skip parts and you can continue to mess around like an amateur, Your choice :-)
