Don't complain buddy, you have a BOOMING business. You do EXCELLENT work and I think of you as my mentor ... ill come help you out so you can take a week off .... you have convinced me to start my own Electronics repair shop. " Jersey Shore Fix " still setting it up, I'm very close to retiring from my Telecommunication Engineering career after 45 years. Tired of all the corporate BS. Thank you for all you do and share.
As satisfying as your methodical fault finding process is, nothing is more satisfying than your face lighting up when you find an issue. Just goes to show you love your craft. Good on ya bud
Also a small business owner for over 20 years with a crazy amount of work, constantly. I found myself in the same situation many times. You just have to pick a date and go enjoy your life. Your customers will still be there when you get back and you’ll be happier and more productive when you return.
Poor thing! I've seen a similar problem before. It ended up being the VRM controller being defective and it would send a bad signal to the Gate of the Mosfet, making it blown up. So, you need to verify it. Also, if that card has doublers in order to drive all the Mosfet, it could be just the doubler for the phase that is bad. A scope and probing the PWM signal driving the doublers could help you narrow it down between the controller and the doubler. That's how I would do it. Wish you luck!
Here from Utah. I’m working on getting myself to be as good as you are so that maybe one day we can work together. Thanks for doing what you do and taking the time to post these videos. I feel like a masters apprentice and have learned so much from you. The wealth of knowledge you possess is immense and I appreciate all that you do!
Good! We don't have many even willing to try, and even less that are competent. I'll bring you all my water damaged modules from cars, you'd just love that I'm sure.
Given the current GPU supply issues and high demand from those wanting to upgrade or build their first rig, these cards are selling on the secondhand market for their original retail price, if not more. I suspect the owner would be very happy to see it back in working condition again if it’s economical to repair.
1080 (TIs especially) sell for maximum about the retail price at release, but still under it. On the other side, i sold my GTX 1070 for even 40$ more than i paid brandnew in 2016 lol. But it makes sense, my 1070 was similar to a GTX 1660 Ti, but with 8 instead of 6 GB VRam on the 1660. And even a "slow" 1660Ti cost nowadays nearly as much as my 1070 in 2016. Sad that the performance you get for your money is stagnating or literally GETTING WORSE.
@@harrison00xXx all I can say is I sold mine for more than I paid for it at the tail-end of the last mining boom. I expected it to tank in value with the “release” of the RTX 3000 series but the silicon shortage decided otherwise.
Thats the thing, at some point you have to discard it as a no repair cuzz it takes too much time... It will be great if you could do that to your own stuff on your freetime. By the way, whats the price of a 2060 Super?
Damn thats a tricky one….i think you should give this card a second chance. But you are getting better and better on those videocards, amazing to see👍💪 Greets from austria
A dead video card isn't something you can just go out and replace. I wish NVidia would just focus on making one card series that does everything instead of having a separate sku for miners. Those mining only cards have no resale/reuse value once the mining steps up.
On a result like that i would go another round of testing. If you can somehow follow all of the traces for that mosfet of course, i know we don't always have access to board diagrams. But if the source of the fault were within the next couple components I would hate getting so close and not finishing. But of course you're right, and going down a rabbit hole can just end up leading to nothing. You may find every component is perfectly fine, and the only explanation could be something unfixable like the GPU itself or maybe compromised layers.
I have just watched the video and I know it's too late for making correction to that board but if you noticed dear brother that there is blown capacitor at the end of the video at the time of 27:27 pause the video and you will notice that there is blown capacitor between the MOSFET and the C188-Capacitor that you missed it. but honestly you are doing great job and wonderful videos that deliver educational content.
Well, I trust you have already scrapped. That is a buck regulator (MOSFET and simple inductor), the overheated capacitor is a dead giveaway. Not sure which went first, the MOSFET, or a short on the output of the supply, but clearly the capacitor got to see the unbucked voltage. This means that every part on the supply got the unbucked voltage and has likely departed.
You're the pioneer of using thermal camera to find shorts. I've watched big youtubers say crap about thermal cams and promoting alcohol to find shorts. But now we all know that thermal cameras are better and more convenient. You don't have to poke your finger everywhere and end up in burning yourself. You're a genius.
This video just fortified my reason of putting tiny copper heat sinks on any chip-like component that I come across! I push my GPUs harder than most people and have never had one fail on me! Bottom line is, adequate cooling is the key to longevity! The so called "safe" +80°C from the manufacturer is way too hot. Anything higher than 65°C is not acceptable and will damage your hardware in the long run!!
for the free time, you can say no... or explain that packages accepted will have a xx week delay etc. Overwork yourself will lead to a bigger queue in the long run. But I guess you already know this.
Why not try replacing mosfet again and check memory banks for short with thermal camera on first boot. The other thing i can think of is replace both memory mosfets and driver altogether, because sometimes one of those 3 can short something of the remaining 2 parts, even though they seem to be fine when measured with multimeter. I hope this helps and would love to see more gpu videos. Best of luck!
I use to do low level electronics repairs. I did it for years but took a break and step back from it. It’s like you said it takes up so much of your time, and it’s funny when you step back for years it shocking how much you forget things when you go back to it. I still do it but more for myself than others. Sorry I’m not Local I would give you a hand.
Why not just continue using your "voltage injection method " after the mosfet ? It's only configured as a switch /"relay". Set the normal voltage and limit it to 10mA to 100mA and increase it if necessary. If there is some short, it should pop up on your thermal cam (like it did in the stage that did control the fet ). Way to late to add some thought to the table on this issue, but I just saw the video so its new to me 😊😅. It's interesting watching your work 😎👍
replace the SOP-8 beside the inductor.. wording (IADPH).. that is the one caused missing 5V..without 5V.. u will not have 1.8V 1V Vcore and Vmem voltage
Build a test MOSFET fuses only. As for employees,check the local college computer lab professors for potential cantidates for on the job training/ credits.
I agree be finished w it if all that and does not work. But include a post visual inspection to see nothing overlooked. Considering how many repairs you made , not for nothing. If it ends up a donor is a plus. Congrats on graphics card fix.
🐨 Yeah Calling Chips that are the same as a "sister" or "Brother" I agree should preferably be referred to as a sibling.. "APU" Err-"As Per Usual" I dropped a 👍 because of your out loud thought process, if only every one in the world communicated their line of deduction as cleverly as you do..
The replacement chip number is AL 00 0H 1L But the original chip was AL 00 0U 1N Idk if both of these modules work the same but i noticed they are different By the way your work is unique good job man 👍
my 1080ti is 4 years old now and still rocking, also saved me from heartache of not able to buy the RTX 3000 series because of zero stocks or paying almost double the SRP
Need to pause your online ticketing for new packages and then you can focus on clearing up your waiting list and once it is done then you can go on vacation
If you have too much work and you can't hire additional staff, raise your prices. The workload will naturally decline and you'll make the same if not more money.
I would recommend, moving out of your store location, stay away from walk-in and over the phone customers, they just take up more time explaining. Focus on the online store.
Id rather be a poor man than look back at life and see all the years missed with family. Just to make videos for us and fix others peoples stuff. Always always put yourself 1st.
He might be working extra hard to ensure his children are able to have an easier life. It's what a dedicated father does. When your family is the most important and you come from hardship, you can't help but want the best for your children.

@@sipansibabdreddknot5179 They might know of each other, But Louis is Macbooks, he has other techs for Data Recovery etc. besides, Louis is in Florida right now with Erica.
I just remembered. I saw a vid where if a MOSFET didn't get enough voltage on the gate it wouldn't full switch on, and so burn out quite easily. Maybe it's the control chip.
depends on the hot air station. some use 480, some 450 some 500, seen many different settings. and air is also different with each. just have to get one use it on old or dead boards and find whats best for you to work with.
I think you have to change your camera position when we see yourself.... please try to make video oike another youtuber do....it will definitely help you sir ❤️❤️ Bytheway lots of love from 🇮🇳
My guess is that someone gave that poor card an electrostatic discharge, the ESD death. You did a good job trying to rescue it but even if it start to work there can be timing problems at the bus or memory errors creating all sorts of patterns on the screen.
try to replace the mosfet driver ic and if the problem still there,remove the mosfer and power it on it should boot up on limp mode then flash the bios then replace the driver and mosfet again
You need to tell yourself that you work to live, not that you live to work. Take vacations and enjoy your family before it passes you by and you have to deal with regrets. Your reputation proceeds you, you will always have work to do.

Driver for MOSFET is blowing , because its Complementary MOSFET package( 2 complimentary MOSFETs P and N) try to find the MOSFET driver and replace it, then the card probably starts working.
Very nice video! I had a problem on my GPU that the HDMI ports didn't share the same Ground pin and it didn't post any signal until I have soldered a cable coming out of the ports to the ground pin on the PCIEX slot pin.
Logically what would cause a MOSFET to blow, ie, would it be a short after it switches causing an overload/overheat. I guess it's whatever it turns on.
12:23 I'm just a hobbyist techdude, but can you rely on resistance readings when components are on the board concidering they could be in parallel with other components?

That was a major power failure. No power to memory rail means that the vram memory was shorted as well. Not repairable.

Looks like it could just be shadow cast by the flux tbh. It doesn't look crunchy, just dark. Hard to tell on camera sometimes

I think a general rule is to always replace mosfet driver when mosfet is short right?
@@gpudoctor Yes, it is although if you don't have the parts at hand you can try just replacing the single part

Check for more shorted tantalum capacitors.

Sir you are one of my inspirational GURU (means teacher in hindi language). Please tell me how much maximum time you spent on a repair article.
Driver for MOSFET is blowing , because its Complementary MOSFET package( 2 complimentary MOSFETs P and N)
try to find the MOSFET driver and replace it, then the card probably starts working.
Very nice video! I had a problem on my GPU that the HDMI ports didn't share the same Ground pin and it didn't post any signal until I have soldered a cable coming out of the ports to the ground pin on the PCIEX slot pin.
check the back of the pcb,check for bad fuse(near pcie) or diode,it may also be the controller
You are great
thanks for sharing your knowledge your videos are great 😎✌ 🐱👤
The core is fried, You can remove the PEX Inductor and if the short is on the GPU side then it's the core. which this most likely is. Cheers Alex!

Logically what would cause a MOSFET to blow, ie, would it be a short after it switches causing an overload/overheat. I guess it's whatever it turns on.
Is it fine to apply hot air to those capacitors? I don't doubt you know what you're doing, I just thought that was risky with capacitors
