Msi Geforce RTX 3060 Ti Twin Fan 8G (Missing Capacitors)

[jossbnr34]

Hi, recently acquired a second-hand MSI Geforce RTX 3060 Ti Twin Fan 8G LHR graphics card. After spending two days trying everything and going crazy because my PC didn't detect it, and the fans weren't spinning, I couldn't figure out where the problem was. Yesterday, I found that some capacitors were missing, and some were broken. I imagine it might have been due to a fall or something like that. I'm trying to find a diagram of my card to see what type of capacitors it uses and their voltage to attempt a repair if possible. I'm new to this, but I have done some simpler soldering repairs on video games, which were much easier. However, this is a more complex and delicate issue, here are some photos of its current state, and I look forward to your opinions. Thank you very much.

board code ?

board code ?

this is the board code?

[ktmmotocross]

nope thats not.

this is the similar photos of my gpu

[ktmmotocross]

try other side. MS-xxxx

[jossbnr34]

only have this serial rear to the board very strange board

The three capacitors marked with green and pink lines in the first photo appear to indicate that the green line represents 5V, although I'm not completely certain as I couldn’t find the schematic documentation. However, for the other seven capacitors shown in the second photo, I found a reference in the MSI_MS-V397 schematic, specifically in the V397_61 file.

V397_40 is way closer as they use 8pin 5V ic just as his board

这是微星公版图纸A3060-6C，可以参考v397_40

Thank you very much for your information and help ktmmotocross.

谢谢 kisnovo, I'm new to this and would like to repair the GPU, but i don't know which SMD capacitors i should buy right now or where exactly to place the missing ones. If you could help me,

I would really appreciate it. Thank you very much for help.

5V ic is connected to missing part so just trace that pin on that BV. other missing component looks like pcie lanes so all lower positions is capacitors like that white component and higher is resistors like all that black components

Many thanks for your help, the ones from the PCI, which are 7 missing in total, the first 6 in the schematic show 1pF, and the remaining black one, which is the resistor, shows 40.2 ohms.

Then, regarding the three in the photo related to the 5V in that V397_40 schematic, only one appears, which shows 10nF, but the other two missing from my board do not appear in that schematic.

It's such a complex world and at the same time interesting, just like fixing car engines, which is my thing, . Greetings, my friend!
