No output, whining sounds and voltage drop in components on GTX 1080 Ti lighting
The GPU ceased functioning previously before moving to repair, yet it recently failed under the same circumstances. Four parts are present (shown in the picture below), one at the lower right was removed, it operated normally after fixing but recently stopped with identical issues.

When turned on, three fans spin consecutively, beginning from the rear (display ports), continuously. The motherboard displays a D6 error, and the VGA indicator lights up. There are also occasional whirring sounds (resembling "zzt") inside the GPU after a short time, and some components, such as capacitors, lose voltage abruptly from 14.4 V to 600 mV during this phase. Upon inspection, none of the parts appear to be overheating or warming up.
The Noises

This GPU is a GTX 1080 Ti with lighting; its specifications can be viewed here: https://www.msi.com/Graphics-Card/GeForc...cification (If the above images aren't accessible, refer to the Google Dive image).
Edit: I discovered missing capacitors near the PCI edge on the card. It's unclear if this was intentional or resulted from the repair process or simply due to age.
Here is the updated image showing the missing capacitors.
From the initial picture it seems like a bad soldering attempt or the capacitor failed. If this matches the actual GPU image, consider removing it and checking if the PCB traces remain undamaged. Otherwise, applying a UV mask to the traces might be necessary.
There are also some loud (more like "zzt") sounds coming from inside the GPU after a short while.
By touch, there are no parts that become hot or warm.
If you're handling the card yourself and run a business fixing these cards, it's important to use a FLIR thermal camera to help identify any heating areas and pinpoint the likely cause of a short circuit.
Hi, I soldered the capacitor, but the GPU needed some repairs before I got it (it was used). My soldering iron and blowing station couldn’t melt the lead properly because I set them to maximum. I replaced the broken capacitor, and only three of the 560 are left. I’m handling the repair myself since I don’t have a professional service or special thermal imaging equipment. I recorded some noise and uploaded it; it should show up in the main post. Here’s the link.
If you don’t mind, could you tell me what UV mask you were referring to?
The PSU you're using to power the GPU is unclear, but the near vertical capacitors beside the GPU's die seem unusual. Based on your questions, it looks like you might be risking a card that could still be fixed. You should check nearby repair shops to see if they can bring the GPU back to its original condition for a fair price. Regarding the UV mask, it appears you're referring to a visual indicator of damage, possibly from soldering issues or other component problems.
I'm using the ROG Thor 1200 Platinum PSU (looks similar to here). For the vertical three capacitors near the GPU die, I used a multimeter and discovered some were 0 Ohm. I tried removing a leg from each to check if they would isolate what I thought was a short, but it didn't happen. The last time I inspected the capacitor under the GPU die (the four-piece package) showed no visible damage. My GPU had issues before I began working on it, and I wasn't sure if the previous repair was still functional or if something went wrong this time.
I noticed the card seam has a missing capacitor close to the PCI slot. I'm not sure if it should be omitted or if it got lost recently. Here is the image, it should also show up in the main post.
