It's VERY hard to show how to use years of experience in a short time. Go check out louis rossmanns videos. They are very good. He also tells the gist of it: Many failures have to do with the power delivery. They can be fixed. But on GPUs it's not rare at all to see a dead GPU chip. This will not be permanently fixed by heating those chips. Replacing them requires very special equipment. So if GPUs have a black screen it's a good sign. Artifacting cards most likely have issues with the package it self and therefore are not worth fixing. You can try to bake them to extract a few extra months of usage.

You need to shield those capacitors from the hot air tool, you're boiling the electrolyte when you hit them with the hot air directly. Not only will they be permanently damaged, you risk having them explode in your face. Regular aluminum foil from the store works as a shield, just tear off a big enough sheet and make it 4-6 layers thick to block the heat. Damaged capacitors can ruin your repair if you don't replace them. If they go high ESR, become electrically leaky or short out, they'll cause more damage that may be difficult or impossible to repair.

How do you measure ESR on such capacitors? They already have a super low ESR that looks like a short on a DMM. I guess you have to remove them, probably can't test them in circuit due to the nature of the synchronous DC to DC converter.

@GGigabiteM

@@haz939 You need a capacitor tester, and optionally a leakage tester. DMMs can't reliably test capacitors. You can get capacitor testers on Ebay for $20. I use this one myself: www.ebay.com/itm/222520569499 You'll need an ESR chart to know what the numbers mean, it won't tell you that a capacitor is bad unless the capacitor is so bad that it doesn't register or shows up as a short. This tester won't show leakage, but you can infer leakage if the capacitance result is wildly out of spec. If you have for instance, a 1500uF cap and it tests at 4500uF, this is far outside the usual 20% tolerance and infers the capacitor is electrically leaky. If the charge that the tester puts into the cap keeps being drained away by parasitic resistance, it will confuse the meter into thinking the capacitor is a much higher value than it actually is. Leakage testers are also useful, but they aren't really made anymore. Your only option is to buy a 40-70 year old unit and restore it, or build your own. In either case you need to be cautious because these leakage testers can operate at high voltages, sometimes up to 2 kV.

Electrolytic capacitors usually don't like hot, but only when they are heating themself. When soldering them in (think about SMD reflow) the heat can be as high as 260 Celsius for a couple of ten seconds. You can check any datasheet about this. So hitting with the hot air for a short time is not so critical. They will explode under current only.

From what I've heard, nvflash locks those cards, but you have soldering equipment and a chip flasher. Those cards can be bought for around 70$.

Wow .Fabulosa the combination of light, músic and electrónic solder

I have a ZOTAC GTX 970 AMP Extreme Core Edition (long name I know) that sometimes works well with heavy rendering and modern games, but sometimes it randomly crashes while rendering, gaming, idle or even booting.Tried it on different computers but there's no difference. The crashes are very random like: full screen random single-colour, black screen whether before boot or after boot and sometimes the fans go full blast at boot with no display not detected with 6 beeps from the Motherboard. These can happen at anytime. I took the card to a technician but he was unable to point out a faulty component. I've been randomly watching repair videos and the card seems OK. One big thing to note is that I removed 3 shorted Mosfets (with no shorts on the main 12v rails) but turns out the Mosfets were not faulty, I put them back the shorts were gone. Later on the shorts on the Mosfets are random so are the crash symptoms still random again. The Mosfet models are five of MDU1513 and ten of MDU1511 the PWM controller is NCP81174. I'm suspecting a contact between the layers of the PCB. It's driving me crazy man. What are your thoughts?

Hi Eli, recently I've discovered your KZread Channel and watched all of your videos. First of all I've to say that you're pretty talented and got a lot of knowledge. But I still don't understand wherefrom do you know where you have to read the voltages. For example from 3:42 to 5:10. How do you know which pins you have to read with your multimeter? Thanks in advance, happy new year and good luck for the future. Moritz

You're my hero! I'm having some trouble with my card... it works but .. I feel something is failing. If you were in my country definitively I would send my failing electronics for repair :-D.

I had a few broken graphics cards off Ebay. Only managed to fix 2 of them. The last one Palit 1050 ti had a blown mosfet in the VCore selection of the VRM and I lose resistor for the 12v sense line that prevented the card from powering up, just drawing around 30ma for the linear regulators. Fix those 2 issues but the card had no display, fans spin and all the voltages and current draw seem normal. Even tried to reflash the BIOS, still had no effect. After all that I managed to short the GPU!! Still good experience I guess. The card wasn't exactly cheap paid more than I should have. The previous owner / seller had already tried to resolder the mosfets as they were not even sitting straight. The warranty sticker on the screw was broken as well. I wouldn't recommend buying a card that someone has already messed with. didn't heated up the GPU in an attempt to reflow the the BGA balls, but that just getting desperate in my opinion. The card probably way too new to have issue like that.

Indeed you explain the way of repairing video cards properly but dude.. the camera is angled way too shitty. At some points we (your audience) cannot even see where you are pointing to the GPU.

Hi Eli, I had a question. I have a vega frontier edition. i took off the stock cooler to triedto water cool it, but i think the thermal paste i used was slightly conductive. I turned it on and it wouldn't show any thing on screen and the whole computer would turn off. I took every thing off cleaned the die and put the stock cooler on. with both 8 pin power connectors plugged in it showed nothing on the screen, but if i plug in one power connector it works, i can alternate this. So as long as one connecter is plugged in it worked. but not after some more testing nothing seems to work. any ideas on how i can repair this? Thanks

Hi one question, I made a mistake and bought one of those cards from a chinese site.The cars is XFX RX570 4GB dual fan. The card works in games perfectly with no artifacts but has the following problem: When in idle status or when browsing a web page,the gpu disconnects (you hear the disconnect sound) monitor turns black and instantly reconnects and keeps doing it many times! I have tried to 1)change PSU 2)try different port (hdmi,dvi) 3)try different pci-x port 4)flash bios 5)tried many different drivers 6)changed the time limit gpu has to give response Nothing works.The strange thing is this problem happens not the day you connect but the following day! Can this problem be repaired? I repeat ths card doesnt have problems ingame

great music! I know this is an old video but dang. Good music.

That is one nice camera holder you got buddy.

I would suggest not to spin a fan while it is connected to the PCB (as can be seen at 2:20) since this induces a voltage to the PCB which can be unexpected and can kill components on the PCB. Also make sure to fixate fans when you use blowers or vacuum cleaners to clean systems with fans.

It was worth it, seeing as I paid $200 for a new GTX 1070 FTW. I think the card died due to stress as it was covered with a silicone grease and one of the small pieces looks like it exploded.
