I literally just had a kitten of mine knock an RX 6700 XT off of a shelf last week, it fell 2 meters onto my concrete floor. No cooler attached, just backplate and bare PCB because I enjoy looking at the PCB. The card is completely functional, no issues whatsoever. It fell from 6 feet ONTO CONCRETE. Directly onto concrete. Nothing damaged. I genuinely don't even understand how people break GPUs anymore. It literally fell. From 6 FEET. ONTO CONCRETE. And it's perfectly fine, no issues whatsoever. I'm still in disbelief that not even a pad underneath a memory chip or the GPU chip was damaged, but, it works fine with the cooler put on.
I enjoy watching your videos , like if someone told me I would sit for hour and half watching you fixing GPU , hahaha , I even learn in progress . Awesome
Thank you so much for talking while you work. This helps a ton to understand especially the 1080ti. Having 5 different ones also helps the overall flow. It helps us when you don't have the specific board view for this board because to see you figure out what is going on is sometimes hit or miss.
Thats one of the most difficult fixes, really excellent job , you don’t have exact breadboard file or schematics or similar board to find the missing components and then you did it 👍
I like watching your videos, learning more and more. Thank you very much 33:28 When measuring resistance, please note: No voltage must be applied to the measured object I have never actually measured it this way. Interesting...
oh men, you were going from missing components into missing components, that at some point i wondered how you didn't gave up on this one. You're a master chief! Awesome commitment there!
I love these multiple part videos, I’m thoroughly enjoying and learning from them. I’m an ET in the navy, so I deal with stuff like this, however not GPUs but I find it so fascinating. Keep up the work! ❤️
Fr tho probably some guy who buyed alot of junk gpu with missing componants and waste northwestrepair time and effort to resell them after at high prices sending 5 broken gpu by the same person make me thing he gonna make profit on people head lol. I hope Northwestrepair charge him good for the repair !
My guess it really was the mosfet all along and not the transistor.. The mosfet wasn't powering on so it was in protection pulling low/high another transistor inturn pulling the transistor you replaced low.. Removing the transistor was a great idea though.. I've used that technique in the past to get the rails up and running and in your case it basically led you straight to the problem imo. It's always a good idea to check all the phases to make sure they are working correctly especially on boards with knocked off components.. Anyways keep up the good work and God bless..
you go to such extreme lengths to save these cards.. so cool to have such knowledge and skill. i have a evga 2070 super that my friend gave me, and when i play cyberpunk the hot spot goes up to 99c... i should probably replace the thermal paste right ? or is that okay ?
Well, it's within official specs buuut I'd repaste/repad your card. I did it for my 3080 this month and hot spot temp went down 15 degrees C from 105 to 90 under full load.
99c is quite high, definitely in need of pad and paste replacement before it cooks itself to death, maybe also underclock and undervolt in case the new paste doesn't help much
yeah repaste it i think, the 2070super isn't particularly powerful, mine's running rn with just one fan and still fine temps, so you could definitely drop that hotspot
The famous reference design with cropped edges. God bless the nvidia engineer who put 1.8, 5v 12, and memory below each other. Btw if you find 4 or 8 lines of cap-resistor-coil combos, thats hdmi or DP or dvi. btw #2 the chip IO floating voltage is never gone be 5v. It will fluctuate and wont stay high for enable. btw you can jumpwire at least.
The flux they used is actually rosin, it comes from pine resin, so when you said tree sap you weren't wrong haha, It can be used as an isolator as well protecting pins from oxidation in case of liquid damage
I love this short format of videos, when you can spend so little time to watch only main moments, but maybe next time you can make a bit longer video, so we can have more time to enjoy 🤣
I was amazed that some of the components actually got knocked off at all after seeing you struggle to remove them with a large iron and a load of solder. Great fix though.
leads, wool, strings, rope, laces all tangling and tying themselves into knots makes me believe that String theory is definitely the answer in physics...
This card was messed up so badly (from previous repair attempt ?), anyone else would have given up mid-repair. Nice work indeed. But was it worth it for a 1080Ti, how many hours did you spend on this one? If the answer is yes, you're probably not charging enougth for the repair 🙂
Alex's name is Hussain Ali. When in school his friends started calling him Ali, shortened it to Alex as a proper name and he became Alex to all his friends. He has a degree in Electronics. So when out of school he became a used car salesman until his uncle started a repair shop. Alex discovered he could make his uncle more money when he found out how to repair boards. Any board. Now he has piles of work and since he repairs on the internet people discovered they could send him their boards and got swamped by video cards.
I like youre mumble here at 5am with a ton on my mind you help me stop the thinking you seeem like our kind gotta stop the brain with for you soldering for me building pc builds for whoever is the client hehe thanks for helping slow down my thoughts asnd laugh with you bud
so, there are many pads that have no components on them, but how do you know which ones must have components in them and which ones don't. for example when you soldered the chip on the first card, there was also 5 empty pads similar to the pads that you soldered the chip on, why didn't you solder another chip there ? (this question applies to caps and resistors also,)
Right before you mentioned Alex i was just thinking he sent you those cards, probably donor cards or pure garbage cards to make you spend time on them and lose money..
i don't know if you will notice but i just want to ask if 800ohms on 3.3v is normal? card keeps blowing the core vrm, already replace the controller, fets and drivers at it keeps frying the fets and sometimes the driver too, core is not dead short, just above 3ohms
I think that some one made that mess on purpose, being curious if you would find out what he did. Then he send you this card as a "broken". Idk, just my guess .
where do you find these schematic for gpus i really need the schematics specially for older gpu s and i dont know where to look or what is that software you are using or anything at all about where i can find these schematics for gpus would you please just point me to the right direction please
its probably from someone who had a miner. we like to use similar cards. Looks like he used wrong cables or adapters and fried a bunch of stuff then tried to fix it himself lol and mangled it.
I have a MSI Suprim RTX 4090. It isnt the liquid OR the Suprim-X and it’s hard to find information on the non x version. I don’t recall having seen one of those come through on one of your videos. I am hoping that means they have better than average quality, or at least the funky little stand they have in the box (that I am using) with their cards helps enough to prevent the cracking issue. If anyone reading this has had any experience with the 4090 MSI Suprim could let me know if it’s a card to hang onto, or to sell before I have issues that would be awesome!
This one resistor was standing up for the right to repair ✊
Got'em.
Really shows why it's good to have a backplate on your graphics card, even if it's only plastic, protects the small SMD parts from being knocked off.

@@RNG-999you know it was just a lucky one :)
@@RNG-999tell us again how high did it fall and what did it land on....
@@Jasontvnd9 Yeah can't quite tell 🤕
@@RNG-999 try that again with the full cooler on it.

The VGA Whisperer in action ^^, thumbs up Sir!
I can understand you initially not wanting to show yourself on the internet. But you are good at what you do.
This is a therapy for me, thank you

amazing job, rooting to see the second part!
What a heck is ppl doin to their graphic cards!? Dragging the naked cards over their carpets ripping of components!? 😳
These were all probably used as donor cards 😂. Used donor cards lot off Ebay or something lol

dammn dude, this one was a challenge, well done on the persistence
Another great job! Well done
Man partner, I could feel your tired all the way over here : ) Amazing job, well done!
What are you? a God or something???!!! you are great ... enjoyed a lot ... keep up the good work.
Fantastic work.
Thanks for the video, it is like I always hopping you trow one of those against the wall at some point. XD But yo did it!
What an awesome display of technical prowess.
I think you should wear a solder vapor protection mask.
The vapor is very dangerous to your health in the long term.
Thats what the fume extractor are for
@@Thelemorf That's not enough for him.
He's very close to the source, so the vapor will touch him before get suck out.
Amazing fix as always.
That nasty flux you mentioned is plumbing flux. Plumbers use it when working with pipes and such. The wrong stuff for circuit boards obviously LOL
you go to such extreme lengths to save these cards.. so cool to have such knowledge and skill.

Make sure the heatsink is having good contact with the core, could be part of the issue
You need to add a flux cleaning and screw sorting charge to his bill. 😅
impressive. enjoy your sense of humor!
The famous reference design with cropped edges. God bless the nvidia engineer who put 1.8, 5v 12, and memory below each other.

Love the voltage injector probe mod!
Great job!
I love this short format of videos, when you can spend so little time to watch only main moments, but maybe next time you can make a bit longer video, so we can have more time to enjoy 🤣
If you get it disassembled send it back disassembled. You done your job repairing the graphics card. Cheers!. 😊
But if owner messed up the assemble before testing it, he would send the card back for no fix. It's a hassle but assembling it is the best option.
What is wrong with these customers?!?
I call those standing components (that resistor) "Tombstoned"
Great, a long one... I will save this for my night shift. It makes it go faster. Thanks.
That resistor is waving at you. 😅😅😅
7:44 add the voltage on the box and connect to the same existing ports and have the secondary on 0, increase voltage when needed
I was amazed that some of the components actually got knocked off at all after seeing you struggle to remove them with a large iron and a load of solder. Great fix though.
leads, wool, strings, rope, laces all tangling and tying themselves into knots makes me believe that String theory is definitely the answer in physics...
If the transistor in question is 2N7002DW - this is a double mosfet, and they do go bad. Rarely, but they do.
That time travel sneeze xD
Hi there, you are really incredible
2:40 Just say No. At 1:08:27 Did you leave that screwdriver beneath the board powered on? Hopefully there was some clearance.
2:08 ah I see, that must be the rare 10gb variant
All these 1080ti videos are making me nervous about my recent msi 1080ti purchase lol
Is that a custom 3d printed bracket for your microscope attached to a TV wall mount? I’ve seen a few and I thought about trying to make one.
This card was messed up so badly (from previous repair attempt ?), anyone else would have given up mid-repair.
Nice work indeed. But was it worth it for a 1080Ti, how many hours did you spend on this one? If the answer is yes, you're probably not charging enougth for the repair 🙂
Great video. Question: What kind of soldering iron do you use?
A hot one
I also have a broken 1080ti, great card! Shipping it to you would be 80$ one way 😢
Binge watching Tony. Who woulda thunk it? Part 2 coming up!
That stuff around the coil looks like rosin
you do good job on this 1080ti , what brand of solder balls you use ?

Lifted coils is a sign that they had searched for a core short
thank you
12:02 You drew a pigeon there.

that one resistor is how the card is wirelessly powered with nikola telsa technology lmao
think this guy buy a lot of 1080 donar cards and sent to you to fix them all.
looks like somebody unknowingly purchased some old doner boards and now your fixing them - lol
That tool you use for powering the cards is a DIY project? I want to copy that
Needs good lighting and white table and everything will be perfect.
Do you also work on motherboards? Or just GPUs?
are you sure that was not one of them new Bluetooth resistors, but i like the connection to the cosmos.
Right before you mentioned Alex i was just thinking he sent you those cards, probably donor cards or pure garbage cards to make you spend time on them and lose money..
This user decided to use his internal flux to fix the board
best show around !
This video made me want to stop trying to learn GPU repair, and cry...
27:40 maybe its "nasty" because it soluble in organic things like fuel or sth like that and not in water like acids?
i don't know if you will notice but i just want to ask if 800ohms on 3.3v is normal? card keeps blowing the core vrm, already replace the controller, fets and drivers at it keeps frying the fets and sometimes the driver too, core is not dead short, just above 3ohms
Have you ever fixed a GeForce 2MX that is PCI (Not PCIe) based?
I have only one question. Is Wick ok?
maybe cause of the non working phase the en signal was going low, had same issue in 3000 series gpu.
I think that some one made that mess on purpose, being curious if you would find out what he did. Then he send you this card as a "broken". Idk, just my guess .
How in the hell do so many ppl break their gpus? I have owned dozens of gpus and never broke any
what scope are you using and camera for it?
where do you find these schematic for gpus i really need the schematics specially for older gpu s and i dont know where to look or what is that software you are using or anything at all about where i can find these schematics for gpus would you please just point me to the right direction please
Bro, you gotta get a 4K camera. Please!
The first one is the least bad?! Dang. I thought it was nasty already.
1 down 4 to go!
its probably from someone who had a miner. we like to use similar cards. Looks like he used wrong cables or adapters and fried a bunch of stuff then tried to fix it himself lol and mangled it.
lol for the picture !
Big boss mustache ? 🥸
Why there is no tantalum capacitors on this PCB? were theyv been removed?
Wowza

From my limited experience they are very good cards. Solid build quality and good fans/heatsinks etc.
put link to your thermal cam
I wish I was grounded to the cosmos bro! lol
You are very pretty. Have a nice day, you're very intelligent too!
Is 1070 ti worth a fix?
29:38 I literally shit my pants 🤣
Without the exact schematics for the board, thats not cheating
Seems like someone bought donor boards and send them for you fix.
🥳🥳🥳
I don't understand who the hell repairs 1080Ti when a used one costs only about $ 70 USD here in my place.
1080ti s live on!
Yes
I have one in my system, the thing remains a beast even today
