How To Locate Short Circuit Mosfets on a GPU. Learn Electronics Repair #063. Short Circuit Tracing
Learn Electronics Repair #063
In this video we look at the VRM circuit on a Graphics Card (GPU). We have a short circuit high side MOSFET, but there are 12 MOSFETS in the VRM circuit and we need to trace the fault to find which phase actually has the faulty MOSFET
This uses the same technique as the video I uploaded which looked at CPU VRM circuits. In that case we removed the CPU to aid in fault diagnosis but will the same method work when we can not remove the GPU chip from the board. The GPU itself has a very low resistance from Vcore to Ground, in fact it is less than 1 ohm. This is normal for a GPU but will it prevent us from tracing the faulty MOSFET?
You will just have to watch the video to find out!
You can also watch the CPU VRM video here
