Hi!
Managed to get a Gainward Phantom GTX 980 in an auction for a bin with components.
No video out so I started fault finding and found a blown fuse for 3 mosfets. Started checking for shorts and found what I think is a short through all of those 3 mosfets; 0.1 ohms between "VIN" input and "VSWH" output. All mosfets in this gpu are the same ones (NCP5369) with integrated drivers and when I tried measuring the other ones through these ports they were somewhere in the kilo-ohms range.
So, could I safely assume all of these 3 mosfets are blown and need to be replaced or have I missed something crucial? checked everything after the mosfets and can't detect any other shortages.
Is it common for a mosfet blow and take for example in my case two more with it or is it something with the Gpuchip that would break all these three mosfets and the card is inreperable?
Thank you for any answer, this is my first gpu fault finding and I hope im on the right track with it!
Attatched pictures of the Faulty components and datasheet for the mosfet, and here is the link for the PDF of the mosfets: https://cdn.badcaps-static.com/pdfs/...fa920848ad.pdf
