Why is my graphics card missing two chips?
I'm currently trying to repair an MSI GTX 1080 Gaming X graphics card and want to replace two chips. I bought the card at auction for €50. According to the previous owner, the GPU stopped displaying images from one day to the next after a system backup. I opened it and immediately noticed that two chips were missing?! Does anyone know more than I do and can tell me if this is correct and if there's a connection?
I can't find anything about this on the internet, it would be great if someone could find something there too.

Well,
that is a missing voltage phase.
The GTX 1080 should also run without these.

Do you know if there’s a driver chip somewhere to buy? I found the Mosfet on the Internet.
The HF coil is missing.
I don’t know where to get them.
There are also manufacturing differences.
Is the card even recognized?

Well, ventilators turn, LEDs go on and they get warm, but no picture.
Nope is not detected where is the coil missing?
In any case, this is not so planned, as it looks strong that there were chips. In some cards it’s normal that chips are missing, but this doesn’t look like it.
Accordingly, it cannot actually know anyone other than the person who had the card before it was broken should be bought it needed.
That’s normal. Is ne Powerstage and the associated driver that were provided in the reference design but were saved away
Edit: My mistake, that was the 1070 Gaming X. Here the two should be present, were probably removed from someone. So it is possible that the error is
Can you buy the driver chip somewhere? Or a similar one of the same purpose fulfilled?
It’s difficult, it’s a very old card. The Powerstage is ne OnSemi 4C86N, unfortunately I don’t know the driver
Nevertheless, thank you very much.
If you don’t know how well you’re with PCBs, why are you even trying to fix such a card?
For each card there are online blueprints to the boards, as you can see if there really is a component missing or not. Where exactly you find the blueprint on this map, I can’t tell you.
An attempt is worth it, and you can learn a lot about brazing. There are pictures, he’s not missing. Thank you.
