I'm receiving a lot messages as " I bought broken card from Ebay, I baked it but still doesn't work, you know any ideas? ". So here is an answer.
From my opinion you never know what you get. Lottery. You can buy a card and it has a slightly short like with a cap, or it might be short across GPU and memory and then you get a peace of
textolite.
Also in this video shows step by step how to do diagnostic on R9 390 graphic cards. Thank you!
You can always leave your thoughts below)
this video inspired me to learn how to solder.
i then fixed 6 dead graphics cards, sold them and bought new pc parts.
thanks for the inspiration.
Do you have tips on how to learn that ? I right now myself have a r9 280 and the card is working but doesn't give display and if it does after a few restarts, it will crach when it comes under heavy load like csgo or just playing fifa
How did you fix those gpus?
@@mr.stealyourgirl1779 He didn't. This video is 11 months old. His comment is 10 months old. Do you think he went from not even knowing how to use a soldering iron to fixing 6 GPU's in one month? Not a chance. That's not even enough time to buy the 6 dead GPU's, fix them, sell them and purchase new parts, even if he already had the know-how
@@-dazz- thank god we dont have brilliant people like you working for the FBI
@@-dazz- could be possible. I fix electronics for a living. Mostly phones and PCs, just trying to see if graphics cards are worth it.
Can you make a full guide on how you repair a gpu? tools needed, finding shorts, etc....
How do you send power to graphics card to find hot chips???
Would definitely donate if you did!
Yeah! That'd be great actually.
multimeter and that's all. and knowledge about how to use it
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.
Finally found a channel that can actually fix faulty gpus 😃 but why so few subs? You should be on the top of the repair list! Thanks for the awesome vid 😁
Plenty people do it just the people who make the components don't want you to fix them when they have newer better stuff coming up.
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.
@@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.
@@zsoltkohler7096 Ambient heat of a reflow oven is very different from concentrated heat of a hot air nozzle.
I've seen plenty of people hot air tool capacitors until they popped the vent (radial electrolytics) or exploded (SMD electrolytics).
I've had the aluminum foil trick backfire on me since it insulated the heat, I probably didn't have small enough tip on heat gun though.

if he knew anything about editing, he would have saw that spike in audio
I can't afford to be a patreon but Ill watch your videos so I can learn more and hang out :). If you put ads I don't mind. Edit: that was an awesome repair! Good job
I love this kind of videos how one man's trash is another man's treasure. I bought a MSI GTX 1070 ti on ebay still waiting for it in the mail. Pretty much self learning about things right now I also fix broken broken glass ipad air 2 and it's such a good feeling fixing things you just gotta practice at being good about it. You will never break something if you know how to fix it, unless is broken down to a point of no return. I also fix some jbl speakers I do love those speakers 😁
how are your repairs going?
WOW I've been watching your stuff for a while now. I work on robotic automation for my career. so everything you test makes complete sense to me. I bought a sapphire r9 390 with very similar pcb, and the exact same issue. when I was troubleshooting, and got 66 Ohms across to the drmos I instantly remembered this video. just shot here to confirm my suspicion as I normally work on robots not pcb's. Thank you! I will be making a patreon contribution!
rip ears ..
What do you mean...? The audio level is perfectly- *AHHH! WTF!* >_
Bro how is UA-cam not paying you for these videos. So informative, very well produced and edited. Love the music.
same question ? i dont understand how yt not paying him for videos can we get some explanations why?
This is so cool, I wish I had the knowledge to be able to repair stuff like this. :)
I see you haven't been to the Louis school of flux usage.
lets aaad a little bit of flux!!!
@@stonefx83 Ye, first time watching, I was like damn, this man likes his flux..
just the right amount of flux..as said by rossman
A micro-Paul of flux
Your English is spot on. I understand everything you say, thank you for the great work.
You must be some sort of savant to repair so fine a piece with such a huge soldering tip. Like one wrong move and you could have screwed it all up but you moved fast and didn't miss once. Very impressive. You really need some proper equipment because you definitely have the skills.
you can use flux on the solder points so it would be easier just like what he probably did based on the color
I saw the thumbnail and thought to myself that this is going to be one of those "rehot cpu bro" type of videos, but was pleased to find an actually proper repair. Keep up the good work!
Dayum... this guy could bring anything back to life.
Just a few days ago I bought by mistake, an XFX R9 290X 4Gb paid 55$ shipped, on ebay, and today comes a video of Eli on the subject!
I will take a cue and try to fix it, hoping everything goes well.
As for Patreon, it's a nice idea. I wanted to make a donation but I did not know how.
You will surely improve the already excellent quality of your videos, and yes, you absolutely need a tripod for that camera! Ciao!
Can you maybe try if it works to solder a DVI port and flash the BIOS of a NVIDIA P106-100 Mining card?
This would be a great find if those cards could be repurposed as an actual Graphics card including Display out.
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$. If the mod works, you could transform them into a full GTX 1060 6GB
wow man: it takes more than a bios flash to turn a crypto miner into a graphics card. Even welding on an hdmi would need a mux chip.
@@paublusamericanus292 I don't know if modern GPUs still use dedicated mux chips. At least AMD have them integrated onto the GPU as far as I know. Not sure about nvidia though.
But probably there are a lot of passives missing like resistors and capacitors.
Mate I didn't know we were going to the club at the end of this Haha ; )
Cool video man. Keep posting and improve your audio.
YO ? how is UA-cam not paying you for these videos. So informative, very well produced and edited ? i dont understand how yt not paying you for videos can we get some explanations why?
don't know where you are eli, but you are the boss. good work, and quickly figured out this one, it could have gone way further while failing, but now it will run someone for 3 or 4 years.
HI and thank you again. Good to see you witha patreon page. I would ask for videos on following: 1. identify common voltage rails on a video card and the components you should be looking for where you can test for these voltages. I have a 1080ti card i have been working on for all year on and still have not been able to work out what is wrong with it. This may help. Thanks again. Alex...ps: SYKAAA
eli: with that memory chip up top row looking so ragged I was sure it wouldn't fire up. good job eli. way to go.
This video inspired me not to buy defective cards, spares and repairs and in bad condition! Thanks!
I'm a little confused, how did you figure out it was that capacitor and memory controller? how did you know what parts to replace them with? Great video btw!
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?
finally found real tech who explain well with actual result :)
thanks! I learned something today. Thank you for sharing your expertise.
wow this is very cool! you just replace 2 tiny components and the gpu works again! :0
borefittyfie: the trick, or the huge knowledge is knowing what and why. that you do with your knowledge and he is brainy.
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 Eli,
recently I've discovered your UA-cam 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.

Wow .Fabulosa the combination of light, músic and electrónic solder
You are good on this. Keep going don't stop.
Wow you are brave. De-soldering near electrolytic capacitors with not covering them :)
Love the vids man, keep it up. I hope you get to 100k subs soon.
Song used in video is: Siro - Xinspiratio ;) ;)
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
Did you flash the proper bios? You might need a cheap programmer from eBay. It has a clip for the ROM chip
Hy man did you find the problem?
this one "thumb down" is from the guy you bought this graphicscard .... xD

Hello, if you could make a video of everything that needs to be checked and how to do it in detail, it would be a great contribution to the community that follows you. And you would also help those of us who have graphic paperweight cards. Thanks
ye I buying GPU regularly on ebay before and buying broken gpu I make nice money over year but as I move out of UK I can do this anymore but is always definitely good idea nice to see your channel improve I wish you have this gpu repair videos about year ago as will defo help me now is for me just for get some information good job as always my friend
wow bro youre so skilled from where did you learn all this things, ofc practice makes better but ..wow youre like an engineer from SILICON VALEY:D big up
U hear this constantly I have a gtx 980 ti am familiar with electronics not much with surface soldered boards but enough to know flood soldering is a tedious process.. card gets power fan stays on high with a black screen ...mosfets or ? There is no short in pcie plug
Impressive..... this guy deserve way more subs that he have allready...
Respekt, well done 👍🏻👍🏻
Subscriped you ✌🏻
This guy is a genius! Love u♥
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 wish I could have such diagnostic skill ......
Please do a Mail-In Repair Business... your Skills are really outstanding.
sir could you help troubleshoot and repair my friends videocard...he has an evga gtx 1080ti FTW3...it has no display and led indicator is red-blinking and green/green
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.
So if I got it right; the fuses (DRAM fuse?) was blown due to a faulty/short DRAM controller/driver?
"Suka já zaplatil sto" killed me :D
Man, I love your chanell. As I repair laptops/GPU/mobos myself, I really enjoy watching you. :D
You are very talented. I wouldn't know what to check where with multimeter to begin with not to say about soldering smp components, your gear is elite too. Good work!
Very interesting, Just curious as to the name of the stress test you used at the end of the video?
I love your camera quality and lighting! keep it up with the music too!
I have purchased several broken boards on ebay to try to learn electronics and how to fix these boards. Could you tell me how to find out what the chips behind the GPU are and how to find out the value to purchase replacements. I have several of a couple of brands boards and some of the black chips have no information on them or the board. I have taken it that these are inductors. If not, what are they if you can tell me. I put them on a transistor tester and they read 1139 ohms and at one point one of them read 43.25H. I have no idea about these numbers as they are 0603 parts. Any help will be appreciated. Thanks and stay well.
Great work, i dont know anybody who is skilled and able to repair like you. I think you can earn money teachin interessted people in your area. Soldering for beginners, soldering for advanced, electronic repairs etc.. I would come if i live in your area, but i dont - so hoping for more videos. Subscribe is set.
What replacement resistor/fuse did you use? it looked like a straight 10A fuse.
Hello what is the problem of my video card rx570, its running normally when it first use but after a 20mins my pc turn black screen. And my video card is in normal temperature.. thank you
in a perfect world will be like this to fix them all.
What do you think about uploading fails too?
that's what makes a win
Where do you buy your chips?
I have a question please what if the video card has a power but it freezes when I'm opening the computer with lines sometimes its rainbow or red
I like the work you do very interesting. Keep up the good work and if I ever have a broken graphics card I will be sending you a quick message lol
How do you just look at a graphics card and tell what the problem is? There are so many things going on in a GPU, it’s crazy and you would literally tell which components are malfunctioning is very impressive.
im ready to buy a 2080 ti broken! can you fix it ;]
If its an Evga card under warranty then it can be worth it. I bought what was supposed to be a working Evga GTX 1070 FTW for 200US on ebay, the card was DOA, i claimed warranty with Evga and now I have a brand new card. 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.
same case as my 980ti i guess.. can i ship it to you for a fix?
Good day @Eli Tech, what are the common repair for gpu turns black screen and hangs? Thank you
I think someone who is very good at electronics repair and has all the necessary equipment, can make a lot of money buying damaged graphics cards from online auctions. if you can get 600 dollar card for 100 dollars , you will make 500 dollars for couple hours of work.
I bought a bad GEFORCE GTX 1070 FTW. It won’t post, I checked and the fuse is blown. Is this something you might want to repair?
Hi , i have problem with my vga card , its flicker blackscreen , its can get boot in windows , but after few seconds its turn into blackscreen/not detect and detect agan repeat . . . What cause of this problem
I learned quite a lot from your videos. I will send some rubles your way once you set up your Patreon. удачи
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! Im interested in where to find parts for these graphic cards.. I have a msi r9 380 4gb with the same problem as this one in the video any suggestions
ir3553m
Why don't you use flux when soldering
Also, Ebay is full of scammers. Some people lie that you sent the component broken or with parts missing, and they ask for refund. They're also taking parts of the component and sell them separately. I wouldn't advise you to do business on Ebay.
is is easier to get a card that is oblivious broken (burnt components) or a mystery
I bought a dead r9 290x during the great gpu shortage and used heat gun to revive it... I able to revive it 2 times but both time lasted only 10minutes before dying again. Desperate times.
i need help getting a RX 560 4gb gpu back. just got it from ebay but idk whats causing it to work. the fan on gpu spins for a few seconds, then stops for a couple of seconds, and it does that on repeat. idk whats going on. please help.
I have a question, recently I have a gtx980 which has one of those little things (I dont know its name in english) got burn, I was thinking to replace it I mean its already dead, so I cant loose anything else right? but I saw you make some other stuff beside retire the old one, what happens if I only heat it up until it can be "unpluged" and then I install the new one using the same melted tin?
my components are glued before welding, I am at 430 ° with the hot air station, the component does not come
hi dear i have hp omen rtx 2080 it showing the device is not working properly code 43 did you can repair it ?

Thank you for the free tips
Hey bud can u please share your station temps ? I mean what u use for your heat gun and soldering iron. Love your repair vids
Eli i am your fan Numbers One .
great music! I know this is an old video but dang. Good music.
That is so sick...I would love to know how to do that.
I am trying to replace the main power chokes on my Vega 64 and can't seem to find the exact ones (0.56uH 1712NB). Would this be okay to use(Susumu PCMB104T-R56MT) or should I keep looking?
Hello Eli, which temperature are you using? I have problems to find out ideal temperature for desoldering. Also which soldering paste are you using?
Thank you.
If its a good card hell yeah...even if not fixable keep for parts..
Hey Eli, great Videos! Really like your work! I am thinking of supporting u on patreon. U would be my first patreon than ;)
But i want to ask you, if you could make kind of a list to know what to look for when trying to repair.
So lets say, fans spin and there is no screen and the PC beeps.
What should i check? What measures should i get (voltage on memory, phases, gpu and resistances on parts)?
And if this or that has 0 V or a to high to low resistance, what is the way to repair?
I am from germany and just started this as a hobby. I had luck with one "broken" GTX 970 where i only needed to flash a new BIOS and everything works great.
Right now i have a GTX 780 which don't worked at all. I replaced two 5K Ohm resistors which where burned. Now i have fanspin but no picture and beep.
This will be the Card for my Son (11) which plays on an old GTX 560 :/
Perhaps you could help?!
Hey I’ve got this exact card but the trix oc x editon I believe it has the exact same issue. Can you post a link to the IQR chip I believe is what it is. I’ve already got the white fuse.
Considering you most likely don't have schematics for all the different cards you work on, how do you know what voltage or resistance to expect? Thanks for the video.
Through experience and I bet he took note of resistance ranges and other measurements as his basis everytime he repairs ;)
I just bought a Gigabyte 1060 Windforce OC 6GB in excellent condition for $78. Checked Amazon and it is $379 new.
