Gigabyte RX 6500 XT shortage

[Traptor]

Hi guys,
I have a Gigabyte RX 6500 XT gpu.
The gpu has a shortage where I drew the red circle. I measured 0ohm resistance.
The card won't power up.

Then I desoldered the coil and gave power to the card.
Many voltages are there as you can see on the picture.
On the mosfet of the coil I measured 3.258V, and the shortage there is on the other side of coil.

Somebody knows what is this coil?
Maybe this is the 3.3V line?
(I dont have boardview or schematic so I'm just guessing...)

Good idea injecting 1V here this point to finding the parts what makes the shortage?

hi, have you fixed this gpu card? I have here the same board for repair with no short but I have 12v power rail only. I think first thing to do is to check 3,3v power rail and when you do it maybe all the others voltages will be ok in my opinion.

the gpu card powers ups but with 12v power rail only. Actually a injected 0,80v on 3.3v coil and the voltage went down so I imagine I have a short but I still don't know where. I will desolder 3,3v coil, power up the card and see if others voltages come up.

Hello again, my situation is: I do not have EN voltage on pin 2 of gs9216 in order to make 0,75v goes up. I attached an image for clarify my situation. I assume that my point of start is where my image file shows because I have 12v, 5v and 3,3v from pcie slot only. any help is pretty appreciated. is there any compatible boardview or schematics file to help? ty. Yellow line connects: gs9216 pin 2 to a resistor and resistor to dual Nmosfet pin 6 where I have 770mV only.

I jut managed to repair this board and on coil that you say you measured 3,258v actually is 1.10v power rail.

Hi, what does that voltage correspond to? PEX?

Hello, it is 0,75V power rail.
