Love learning from your work! You really are providing an invaluable service to the right to repair community. I managed to repair my Asus G751 thanks to your hard work! Been using that laptop for almost 7 years straight now!
You’ve helped me identify board issues in analytical lab instruments at work many times. I don’t have a lot of skill in repairing the boards, but knowing what the problem is helps enough as a Field Engineer.
Amazing job to find that. That was super hard to spot. Your troubleshooting speed is phenomenal. I was so glad to see this video post as I know you are extremely busy Alex. Hope all is well and happy holidays!
Moral of the story: if you don't see something look harder and from a different perspective/different conditions, but most importantly, experience matters when it comes to meaningful observation. Life is like that.
Yay another video :D Great catch Alex :) If no components light up when injecting "voltage"/current, you can measure directly between chips (DRAIN and SOURCE) in mV range while injecting current. The chip with lowest reading is shorting the board. This makes the work many times more effective than removing each chip separately ;) It would also work with multimeter in ohms mode, but you would need an extremely expensive ohm meter that can measure low resistance with many digits and very unreliable since the pressure of leads would change the reading.
the INJECTING OF VOLTAGE technique together with the thermal cam is i think the most effective and fastest way in solving most of the repair... amazing
Watched the thermal footage twice. The heat spot was very visible when the current was switching ON & OFF. The component cools and heats quicky . Masterful technique !!! Would I burn my finger if I used by finger as a temperature probe? Lol
I wonder if by recording the thermal video signal, and playing it back on loop at a higher speed, hard to notice changes become easier to locate. (slight fluctuations made rapid)
I figured when I saw your last video of there being a short on that same 12V plug that it had to be the same issue. Definitely hard to spot, looking forward to getting my card back in working order. Thanks so much for your hard work and expertise.
You make the seemingly impossible repair not only possible, but fully documented! Tell your viewers: "Did you see why I troubleshooted this way?" "You don't need an expensive IR camera. You don't need a microscope. You need a basic understanding of electronics, and you need to pay attention to what the board is telling you!"
What is alcohol gonna do for you? Well.... for one it smells nice - lol. Great job Alex, you are the master in repairing video boards - the immense amount of knowledge has made you the place to go to for these defects. I truly enjoy watching you work.
i watched and re watch even after Alex point out can't see the difference. It is the difference skill and experience had so he can see the miniscule heat.
I don't know why I keep watching your videos to the end. I Know nothing about electronics but there's Carisma in the way you find the faulty component each time, whether it's a laptop, a GPU, an ipad...
A v2 thermal camera might speed up this type of diagnostic proces where it is harder to see the temperature changing after injecting voltage 😉. Thanks for sharing another vid, love to learn about the components on all the boards and the structure of your method makes it easy to follow along. Greetings from the European coast!
The 3080 was released on September 2020. Surprisingly it has no warranty. Must be one of the very first batches to be sold if it ended up in your table.
Have you thought about a stand for your thermal camera? Just a quality of life thing and my personal opinion. I like having as stable of an image video as possible.
Hey alex what do you do if you don’t have any donor boards for asus laptops Mosfets? Do you order non functional laptops or the specific part? Where do you get them if you don’t mind me asking. Thanks!
Hey Alex, love the videos! Thank you for taking the time to upload and share! I was wondering if you had a video going over how to inject voltage/where to inject it/ what tools are needed or anything that covers that aspect of your line of work. I'm sure there are plenty of vids that may discuss that topic but it could make a decent video if you didn't already have one uploaded about that subject. I personally would rather watch your video about the topic than others that are out there.
🥶🥶🥶 If it will be a fix the client should definetly buy performance thermal pads and change them also quality thermal paste. Such consuming card needs very good cooling and the heatsink is not the only thing that matters!!
I have the same issue with my Gigabyte RTX 3080ti, just happened yesterday while playing Valheim. Fans spun to 100%, screen shut off, no HDMI signal. Went to reboot, and it wouldn't. When card is plugged in, PC doesn't boot. When PSU cables are taken out of the card, the PC starts. Sending an RMA for this card, second time now.
On different video cards, the thickness of the thermal pads is different. Each manufacturer has its own nuances. How do you know the thickness of the thermal pads? And what thermal pads do you use when assembling a video card after repair? After all, if you choose a thicker or thinner thermal pads, then the fit of the cooling system will be incorrect, which will cause the video chip and video memory to overheat in the future and they may fail. How does the big boss collect these cards back?
Notification sqaud! lets see if he reads the comments. Did a charge port on an iPad 7, I've done many but on this one I lost display after. Battery was isolated before anything was disconnected up until everything was re-connected. FPC connectors are good, filters tested good and no shorts, any ideas?
This guy has immense knowledge of his line of work.

just like to say i love listening to your thought process during the fix - you are easy and funny to listen to. well done
I like the work you do Alex to educate the community on issues of repairs are concerned. Thanks may the Almighty reward you abundantly.
Ameen. He's a good man.
Finally, a video after 6 days of waiting! feels like a year of waiting. 😁
Good job mate, waiting for part 2
You’ve helped me identify board issues in analytical lab instruments at work many times. I don’t have a lot of skill in repairing the boards, but knowing what the problem is helps enough as a Field Engineer.
You're easily the most genius computer repair person I've seen. Never would I have thought I would enjoy watching videos like this. But I do!

Amazing... it was very hard to spot but due to your experience working with these cards you know. Great fix so far. Part 2 will show the end result
the INJECTING OF VOLTAGE technique together with the thermal cam is i think the most effective and fastest way in solving most of the repair... amazing
gone for six days, i was checking my notifications daily, this is the only channel i have the bell on, invaluable knowledge

Nice to see the experience we have gained
Helps you find the fault quickly
was curious why you haven’t uploaded any videos in the last 6 days, but alex is back at it again
I figured when I saw your last video of there being a short on that same 12V plug that it had to be the same issue. Definitely hard to spot, looking forward to getting my card back in working order. Thanks so much for your hard work and expertise.
It's really good to see you back. I've missed your videos.
That, my friend, is a very ingenious technique.
Thank you.
Great to see you back!! Missed your videos the last few days!!😁
I couldn't see a bloody thing Alex, but I knew I could take your word for it!
Looking forward to part 2 to confirm your genius!
This guy is crazy efficient in tracing out the issue.
The FLIR-camera is a great tool for locating shorts, myself use a FLIR I60 for repairs.
I don't know much about the electronics but I love to watching you fixing that stuff very good job

Nice catch, Alex...we all should call you Eagle Eye! Keep up the good work and I hope to see a parte 2 ASAP. Regards from Italy.

You find very fast the issue, my respect from Spain!!
That was pretty good how you spotted that heat on the thermal cam.
Alex, you’re a savage. Keep up the amazing work!
i watched and re watch even after Alex point out can't see the difference. It is the difference skill and experience had so he can see the miniscule heat.

Well done, experience is the key to your success.
Love your videos. I used to live a few miles away from your shop and wish I would come by to say hi!
Feels like video released after a month 😃
It's been like 6 days but every video is worth the wait. This has become my favorite channel on TH-cam. Thank you Alex.
Keep on going 👍😎 so far so good. Awesome work with the thermalcamera 🤯
Hats off, sir... you are true master of your craft.
Really enjoying these videos.
nice and fast fix , can't wait part 2 👍👍 may be the owner on this card have a weak power supply ,it have to recommended 1000 w

Alex, I missed you. You were gone for a week. I actually got worried. May Allah keep you & your family safe and happy.
keep up the good work, brother from morocco 👍👍
Colloquialisms are definitely the hardest part to learn about our language!
Alex is a master short finder
Love your watch Alex. Good job.. better than factory
your trouble shooting style is awesome..
Hard work and clean work, thanks for sharing, I love it.
Old camera angle 💕
Congratulations, you are great!!
We know how much you are Busy ! But please don’t stop making the videos.
When the going gets tough….Northridge fix get going.
Week feels like year.... Finally i can see some more magic now.
Alex, check that big black cap near that cip. It seems like a hole on top of hip
Can't wait for part 2!!!!!
This guy is quickly becoming dear to me
What’s the temperature of your hot air station when you desoldering chips like this one ?
The frame goes by really fast so i cant be sure. But at 5:52 looks like a cap has a hole in it. Can you check just for prosperity sake?
Woah !! Εxperience beat chip short !!! Good Job Alex ...Again👌👌!!!
I'm watching from Philippines Sir. Thanks for your tips and ideas.
The 3080 was released on September 2020. Surprisingly it has no warranty. Must be one of the very first batches to be sold if it ended up in your table.
Have you thought about a stand for your thermal camera? Just a quality of life thing and my personal opinion. I like having as stable of an image video as possible.
thats was a perfect short maybe 0.02 ohms? Cause if was something like 1ohm or 2 you certanly gone see it clearly in the thermal camera right?
Is this new place video or old place video.
Didn't received any 4090 For repair ..
I think some cards might still boot even with a power stage missing? Probably not all of them though. At least you'd know if the core is dead.
Hey alex what do you do if you don’t have any donor boards for asus laptops Mosfets? Do you order non functional laptops or the specific part? Where do you get them if you don’t mind me asking. Thanks!

Nice, i hope you can fix it.😮 good work at this time. Great. Thanx for the video. Greets
At 05:51 at right side of chip black component - I cannot see clear is that a designation or hole in diode (or whatever is that black component)
Could you test the card without this chip? If chips are in parallel, a card should get a picture up, no?
Great job like always
Isn't injecting 1.49v too much for vcore? Like if there's possibility that all that voltage goes straight into the gpu.
When removing BGA chips, do you use flux?
🥶🥶🥶 If it will be a fix the client should definetly buy performance thermal pads and change them also quality thermal paste. Such consuming card needs very good cooling and the heatsink is not the only thing that matters!!
0:00 GTX 3080? What kind of model is that? 😉
The diode next to the chip has a hole on it. Check it again

Are only Nividia Cards send to you? No AMD/Partnercards up to now or am I wrong?
What chip was that? I see many pins are joined by the pads underneath. Could it be a mosfet or mosfet junction?
Usually they are highside and lowside MOSFETs that have integrated drivers and logic aka drMOS.
Why does production solder need more heat to desolder it?
no lead in the alloy.
Good job mate 👍

Nice i like wen u do repair on video card .
Notification sqaud! lets see if he reads the comments. Did a charge port on an iPad 7, I've done many but on this one I lost display after. Battery was isolated before anything was disconnected up until everything was re-connected. FPC connectors are good, filters tested good and no shorts, any ideas?
Is it that the iPad is turning on but the display is not showing anything? Or is the iPad not turning on? And have you tried another display?
why these chips get short.. and how we save these chips..
Can someone explain to me what exactly does PEX do in GPU PCB, there are supposed to be like 3 of them or just one?
Perfect Job, 👍👍👍
Here your friend desorden82, keep up the good work bro. See, you soon. I need more new toys for repairs.
But I have to wonder though, what is the cost of repair vs buying a new card?
no donor board for this card?
5:52
Is that cap okay?
Love from India
Would the new programmable chip work ?(do you re-p chips ?)
Why not cool the entire board down slightly, so that a heat source from a short circuit will be more pronounced
Good job💯
Came in for repair.
Karachi sr ho
you can test the card after removing that mosfet to see if you have a dead gpu core.
Why didn't he send it back under warranty?
