Great job and impressive repair skills, from a 20yrs experienced electronic designer let me say that you can call yourself an electronic engineer more than most of my collegues.
I have been building and repairing computers for more that 20 years but can`t do what you do, you make it look so easy, but I know it is not, I enjoy your video`s very much, thanks and I wish you well.
Thanks for posting your videos. I can legitimately fix electronics after watching you and others on RUclips. Had a lot of previous knowledge, but your put me over the top on trouble shooting and soldering.
"Work smart, not hard." One of the first lessons my Father began teaching my siblings and i when we were kids. That and "If you are gonna do it, do it right."
Its not available right now, even the manufacturer (alpha and omega) doesn't give any details about that mosfet. The closest solution is find any broke 3090 card that produced by gigabyte
@NorthridgeFix That mosfet is currently not possible to buy, because Gigabyte ask manufacturers to not sell them. Gigabyte is taking all produced parts for themselfs. That mosfet is available only in broken GIGABYTE 30XX series cards ONLY!
by taking photos of graphics cards in 8k you help other services, knowing what parts are falling and see where on the pcb what has burned, the service will order parts faster and repair the graphics card faster
For those who asks about why not to use warranty and RMA, I've bought 2 Aorus Extreme 3080, one for me and one for my friend for new builds, I've build the PC's and what I see - total overheating in any application, even in some games. Why that - because absolutely every new card from gigabyte out with garbage thermal pads, which can't handle high temperatures. So I decided to change thermal pads to Thermal Grizzly Minus Pad - gigabyte refused to change it for me officially, so I opened the cards and changed thermal pads, stock pads were already dead, absolutely new sealed videocards on second day after purchase have dead pads after gaming, imagine this garbage pads. So after opening cards I'm void the warranty and my temperatures become normal, especially abnormal memory chips temperature what was around 100°C and even higher, it's 70 degree now in any heavy load
I love your enthusiasm when you fix something. Recently bought some items from you and I can't wait until you have the short circuit injector so I can purchase one from you. Keep up the great work.
You'e really helped me get my "mind right" regarding repairs. In the past I always fixated on the LSI chips. Millions and millions transistors and other internal elements. In a very basic way of thinking it seemed that if you had a group of millions of failure points or a hand full of discrete components, which one has a higher chance of failure. Of course that's not the case. The LSI chips are amazingly resilient and that a "hand full of discrete components" are usually where the smoking (pun not intended) is. Of course when a BIG BOY fails.. clearly it's additional cost and problems than a single FET, CAP, DIODE or... yada yada yads. Much appreciated. Live long, de-solderer and prosper. Cheers.
When you have Alex's work volume it is always a good idea to invest in tools which shorten your work time, even if they are expensive. As the saying goes "Time is money".

I apologize if this is a question that has been answered previously, but how do you personally mitigate ESD? Are the table top covers specifically ESD safe, or is it just a combination of proper handling and the type of materials you lay components on and touch them with? There seems to be a huge focus on ESD in the gamer community, but I am well aware they are not pros like you.
I got my cards and miners at IMINERS,CO and they are great group of people. Cards and miners are awesome, support is insane, shipping is fast and they provide wholesale discount. My recommendation for them.
Nothing. Besides gaming and streaming, nothing ^.^ But in this case, it's just poor card design. So many people with the same model are having the same issue.
It is not just what you do but how you do it, great hosting and top skills with a lot of exp gained over the years, thank you for sharing your knowledge and keep posting Videos. Cheers
i'm only 3:07 in but i just wanted to say that if the issue was the mosfets, especially on a high-spec 3090 - then we should be more careful about which ones we buy and wait for the 6 month reviews for reliability updates on the cards. you might say that it might be because it was overclocked/overvolted too much, but the motherboard is supposed to prevent that sort of thing from happening. so either it was a faulty mosfet? or the mobo was unsuitable for OC/OV.
Hi Alex, Came across your channel a couple of weeks ago, needless to say sir you are a master of your craft. Enjoy your videos immensely. Being in the same trade for 20 plus years I truly have learned a lot from yourself. Keep it up ;-)
I have questions, I just wonder if why sometimes you check first before replacing anything and sometimes you are directly replacing parts until it works. Why is it so? No hate just curious. I just want to know the technician's perspective because I am inspired to repair things as well. Thank you. I love your channel!
Nice Video. With the right equipment and most important thing are KNOWLEDGE and EXPERIENCE make you know what to check and identify the problem. You have my like, subscribe and respect man. Keep it up.
Because you’re from the SF Valley and operate right near where I grew up, I'll help you out. Most of the time when you have a non catastrophic failure on 10/20/30 series Nvidia, it's the lowside mosfet failing closed and blowing the fuse. If no fuse, it will blow the inductor downstream. A blown inductor is easy, just replace it and the lowside mosfet that feeds it....and back in business.If a blown fuse, you have to locate the short like you did. Catastrophic failures such as a blown mosfet/capacitors/etc are usually from a failed highside mosfet. If it’s GPU power phase, then GPU is probably OK. You'll usually lose a power phase when that happens, expecially if no fuse. If it’s memory power phase, then probably shorted VRAM and maybe damaged memory controller on core. Replace all VRAM, mosfets, and voltage controller (gives you your "power good"). If artifacts after full repair, then bad VRAM replacement or GPU core is damaged and needs replacement. To test if VRAM, you need to run MATS. If you can't boot the card or power it up, you can't run MATS. VRAM and any other BGA component should be reballed if taken from a donor card. Without proper reballing, thermal cycle will kill it again.
Definitely going to send in my old hardware to see if they can be repaired. That being said, I'll be waiting until I see less inventory in your shop, because it seems that your queue has grown with your popularity lolol Edit: Also, you should likely buy a lot of components that this video card has, especially those related/sensitive to power. I don't know if you know, but the memory chips on the 3080/3090 (GDDR6X) can heat up to 110C , though miners / gamers are not supposed to push the card that far, I could see a lot of these chips failing due to factory crappy thermal pads not cooling the chip well. Most users don't want to replace the thermal pads, so temperatures suffer. Thus, I believe the memory chips will eventually need lots of replacements. Hopefully you can get your hand on those, though it may be difficult!
I have a card which produces no video signal, but I was able to get it appearing and reporting as an Nvidia device in lspci inside linux. I think this means that it does not have a short, but I think I should still hunt for shorts, since you made it look so easy!
@Northridgefix Alex, I'm looking to expand my computer repair in to nearby large metro area in Kansas. What do you think are things to look for in LOCATION. On peoples' way to and from work? What do you think is the ideal location for our line of work?
sir I would like to ask what brand of sodering station you are using and at what temp and airflow and approximately how many seconds until the lead melts and able to lift the part. Im asking because I just bought a cheap soldering station but I can't lift the chip ncp302150 eventhough i'm at max temp 500c and almost full airflow.
Very nice and helpfull video. Hope you can do a second part of it. Damn, you have so many videocards to repair…thats really a lot of work. Thanks for this video, i‘m looking forward to the next videos
The first revision of the Gigabyte 3080s & 3090s (that are based on the reference design with the small extra cable to the pci charging socket, ergo VISION, EAGLE, GAMING) have been known to have problems with a loose contact between motherboard and the pci socket. Best always check that first, might save some trouble. My card had the same problem and got quickly repaired by Gigabyte. There are some lists online to check if your serial number is affected (old batch), but that is bogus. Officially my card (according to the SN) should have been part of the fixed version, but had to be repaired nonetheless.
Hey mr. flash, how are doing. Today I tried to repair my msi 970 gaming motherboard, I found out that vrm section was shorted. I narrowed it down by flux & injecting 3.7v from a 18650 battery and removed 4 of the mosfets out of 32 mosfets. I was so happy but the sad part was I didn’t find the replacement mosfets (PK616BA & PK632BA) anywhere online. The search is still going. Anyways, just wanted to thank you for all the information you’ve shared & teaching us how to do it, hope you’ll find you solutions too. Best regards 🙏🥳
Fixed an RX 580 that had a bad voltage regulator and a GTX 980 with a bad 10A fuse but barely see them come in until recently with the video card shortage. You certainly see way more cards though.
I subscribed you as my future insurance policy, if need be. Also I’ll try to donate chips (with lesser air in packages 😉) if and when able. Will refer you to others if ever I come across anybody. All the best. God bless you.
You do know your work, but, add some flux all around the component to be removed. Spreads the heat, solder melts quicker, component comes off quicker. And it also offsets some of the heat shock to the rest of the board.
Alpha & Omega Semiconductor: First line = Part Number Code. First two symbols on second line are Year Code & Week Code respectively, the next two symbols on the second line are the Assembly Lot Code. Like the other guy said this appears to be similar to AOZ5332QI (Alpha & Omega Semiconductor).
After seeing that never ending waiting list of the cards that need to fixing, plus other devices that come to him I wonder how he manages a youtube channel, family, a e-commerce website all at once.

These 3000 series cards are practically brand new. Why aren't people returing those cards for under warranty replacement / repair.
Because here, better than factory
exactly, agree. never buy expensive card without warranty, never.
Bought it 2nd hand, Gigabyte refused to RMA.
Becuz they broke the warranty, by overclocking etc.
Or a benchtest that blow up the card.. It happens
Cos even if RMA it'll take forever to get it back.
I don't know why I celebrate with Alex every time he finds the issue as if I was involved lol.
Same reason I do probably - he looks so happy and proud when he's fixed the device or debugged a difficult problem.
Every gamer who has had their cards busted knows the pain.. all of us celebrate life when a card is brought back to life 👍👍

You just need the same board regardless of manufacturer. Go to tech power up for board pictures

How nice of them. Refuse RMA and then prevent 3rd parties from repairing the card by ensuring parts are not available.
And this is why "Right to Repair" exists

Then they would be guessing not repairing.

Fixed an RX 580 that had a bad voltage regulator and a GTX 980 with a bad 10A fuse but barely see them come in until recently with the video card shortage. You certainly see way more cards though.
I subscribed you as my future insurance policy, if need be.
Also I’ll try to donate chips (with lesser air in packages 😉) if and when able. Will refer you to others if ever I come across anybody.
All the best. God bless you.
You do know your work, but, add some flux all around the component to be
removed. Spreads the heat, solder melts quicker, component comes off
quicker. And it also offsets some of the heat shock to the rest of the board.
Your videos are addicting!
Alpha & Omega Semiconductor: First line = Part Number Code. First two symbols on second line are Year Code & Week Code respectively, the next two symbols on the second line are the Assembly Lot Code. Like the other guy said this appears to be similar to AOZ5332QI (Alpha & Omega Semiconductor).
After seeing that never ending waiting list of the cards that need to fixing, plus other devices that come to him I wonder how he manages a youtube channel, family, a e-commerce website all at once.
Super human I would say. Also family seems to be a huge help as well
