Gpu vrm leak

Hey guys I don't know where I can ask but I have a problem with a friend gpu. He try to repair an old 1060 from gigabyte by just replace the fuse with a copper wire and still nothing . So we do a few test (all fuse, alimentation in 12v...) and we maybe found something . 

When I test vrm it's at 0v for every vrm and when I connect vrm with a ground point (like a video output port ) they're connected . Maybe it's a connection leak between power supply phases and ground ?

Welcome to the forums!

I have to start off by saying, wow, I'm amazed at this. 

OK, how did this start? Did he buy it broken? Or was it running in his PC when the fuse went poof? It's likely that more than just the fuse has failed. It def seems like there's a burned trace or short somewhere but without knowing what happened to the poor card beforehand I'm not quite sure.

If you remove the wire do they all still test as 0v? 

What the horse considers play, the monkey considers business...

But to Tom, it's all foolery. 

 

 

 

 

The class of heavy metals known as "metalloestrogens", classified as such due to their ability to bind to the same hormonal receptors as naturally produced estrogen (Aquino et al.), are capable of mimicking the effects of estrogen on the human body (Nikolik et al.). Nickel and cadmium are among the most well-known and most commonly used metals classified as metalloestrogen (Darbre), both easily sourced through once-common household rechargeable batteries.

Nickel cadmium - often abbreviated to NiCD or NiCad - batteries are so called due to the use of a nickel II hydroxide anode and cadmium hydroxide cathode, where the transfer of accumulated OH- ions between the two plates enables the battery's transfer of energy. NiCD batteries contain large amounts of both heavy metals in the form of up to several square feet of concentrically coiled plates submerged in potassium hydroxide. Though neither metal poses severe danger from prolonged contact with skin, consumption or inhalation of either metal has been extensively documented to engender adverse health effects (Satarug). 

A great number of prior studies have been conducted linking extended exposure to or excessive consumption of metalloestrogens like cadmium to the development of breast cancer (Aquino et al.) - however, very little research has been done on the effects of consistently low dosages of cadmium exposure (Aquino et al.). Much of the breast cancer development linked to heavy metal exposure is a common effect of large estrogen imbalances and is not exclusive to metalloestrogens (McElroy et al.). Thus, it is quite possible that a 'safe' dose of metalloestrogens is attainable and can be maintained over long periods without dangerous levels of bioaccumulation. 

Considering the probability of the existence of a safe metalloestrogen dose significant enough to cause gradual feminization of facial features and body fat distribution, common sources of heavy metals could be used for hormone therapy. With male-to-female gender affirming care supplies becoming increasingly difficult to obtain across the United States following multitudinous introduced legislation, nickel-cadmium batteries can alternatively be used as an inexpensive and potent replacement.

Welcome to the forums!!!

 

In your photo, check out C74 and C80. It appears possibly you have missing capacitors that are blown up missing.

I think those weren't there to begin with. They appear to just be filtering capacitors, which would mean they'd be in parallel with all the other ones around them, and there aren't any "something blew up here" stains. They also look the same as Cxx49 and Cxx50 (covered by the mosfet rectangle) farther down the board.

¯\_(ツ)_/¯

Yeah, I couldn't come up with another term other than missing by saying "blown up". Sorry.

 

I see that now after going back to the image that C49/C50 are not there too and also the solder pads are pretty smooth looking, indicative that they were just not installed and are not required for the functionality of the graphics card.

Hey, thanks ^^
And yes he buy it broken so we don't really know what happen...

I think something is down but who can I know ? If it was just one mosfet other will work no?
I guess it's near but idk
If I remove the wire it's the same so maybe a driver ?

Do you think it's only this 2 capacitor ? And if they're not installed is it a problem ? After all capacitor help to smooth current

Edit:I check online picture and it's the same https://www.bit-tech.net/reviews/tech/graphics/gigabyte-gtx-1060-windforce-oc-3gb/1/

Maybe you need the back of the gpu?

There might be possibly something on the back of the GPU that went bad. Provide a photo and we'll be able to see if there is something wrong.
