I have not fully watched all of them, but made it so far to number 4. I would like to thank you for these. Though I had already found the fault in the gpu I was repairing, it helped me rule out any other issues on the gpu. Saved one from the landfill. This guy is awesome.
An excellent introduction to graphics cards, even though I doubt I will ever try and repair one I have always wondered about their layout. Your practical step through is most absorbing. I look forward to the subsequent videos.😊
@LearnElectronicsRepair Thank you so much for this channel! I'm just beginning my journey of learning my away around a graphics card and these videos have been so enlightening. Thanks again!
Just a word of gratitude for teaching me a few basic steps on how to repair a graphics card. So thank you. I've wanted to learn how to repair electronics, but it's been difficult here in the US to find someone willing to instruct me. Out here, noone is willing to share that information. They're really stingy and self centered and it makes me a bit sad. So it's a breath of fresh air to have someone willing to share their knowledge. Anyway, Id love it if you could give me a list of everything that I need to buy in order to repair graphics cards. Everything from test leads, scope, solder, cleaners, software for diagnostics etc... I really would like to purchase an identical video scope like the one that's behind you in the video on the left side. Do you have or can you design one for purchasing? Also, thank you for taking time and teaching me from your video. I am eternally grateful.
Yeah, I know the feeling that is why I quit, after 6 years of the " noone is willing to share that information". I worked my way up in corporate jobs as It HelpDesk-> Network Engineer-> and now DevOps Junior. I miss the whole diagnosing and repairing laptops though.
@@FlorinLupas-l1w well, if you ever find a worthy teacher, or a vetted class, please let me know because I would love to sign up. I'll always have a desire for repair electronics. I've got a history with repairing some electronics because I am a, HVAC(R) technician and have 25 years of experience. So it'll help me get started at least with basic knowledge and how things work, especially with understanding the sequence of operation.
Please be sure to tell us if you are using diode or ohms mode each time you change a check or operation. "Again we are still in diode mode with black on the ground" or " We are still in diode mode or Change to ohms mode and we will check". This is only as I was not sure if you were still in diode mode when you turned the board over. Just trying to learn! Thanks for the video.
Commenting for the algo. I'm sure this info is gonna help me a ton trying to figure out why my repair didn't fix. 😆 Just hope I don't need any extra fancy tools
Hello. Thank you for the video. I have a question. What version of driver is suitable for this graphic card? My screen go grey or pink solid color sometimes and system needs to restart. Is this because of driver or physical issues?
4:33, That top-right mounting screw looks quite crusty, especially at the top right next to the diagonally to top-right pads for the unpopulated capacitor C2761. At 23:23, I might have misheard you but while measuring the voltage you say Watt instead instead of Volt, twice.
Hello and thank you for your informative videos.

Im looking for mosfet replacements but cant seem to find any. Where do you get yours? the mosfets markings are: AL00 9Y 1F Some other mosfets are on the board but i think the AL00 's are the VRM circuit. Other mosfets on the board: QA311 926 09R GS9219 0NVM
Great video as always Richard, thanks for creating a comprehensive guide for GPU repair. I was watching your videos for some time now, you inspired me to try some repair myself. Just now I was checking not working GPU (GTX 980 TI) I bought on eBay, it has some blown fuses on 3.3V and 12V. While checking data lanes, 9-th lane from both side reads a bit different, front ones reads about 0.77 but one side of the 9-th - only 0.64, from the back all reads about 0.64 but also one side of the 9-th - only 0.59. Is this enough indication of shorted core? I'm not finding shorts on any coil.
I would say the 9th lane reading 0.77/0.64 is enough difference to be suspicious, if the graphics card powers up but does not detect it could well be a damaged GPU core that is causing the problem. Have you tried the card on a single lane mining adapter? I would give it a go and see what happens. Of course if the GPU silicon has internal problems, it may still not detect. Keep watching as I will go much more into step by step detail iin the next episodes
Hi i used to work for a computer repair shop and i asked my boss at the time if i could take this broken gtx 970 home to see if it is repairable and he said sure. So i brought it home and put it in my rig to test. It booted into bios fine and stayed on while it was there. And it did boot into windows but it would only stay stable for like maybe a anywhere from a few minutes to secs. I have torn the card down a few times to make sure it is clean and i even tried the oven method and i also did probe it with a multimeter and everything seemed from for resistance wise (because i dont have the proper tools to test it while it is on for voltage). I had it work long enough to try and install the drivers for it, but it ultimately crashed and restarted the computer. I dont think it is repairable, but if it could be, what should i try to do?
Hie Richard ,I like your videos because of the use of pen and paper .The pcie lanes capacitors ,why are they connected in series with the power line ,not across power and ground. If series what is the use of them ,since this is a DC circuit,Thank you're
The PCIe lane capacitors are not in series with the power line, they are in the LVDS (low voltage differential signal) data lines. As the data is transmitted at very high frequencies it easily passes through the capacitors, but they block any DC voltage differential between the motherboard and the graphics card which would easily damage the input circuitry that receives the LVDS signals.
would it be possible for a gpu with some corrosion near one of the memory module to work until you clean it with alcohol. I cleaned the back of a gt 710 and noticed the green corrosion very close to one of the memory. After cleaning its artifacting
Hi! My desktop pc graphics card, MSI GeForce GTX 1060 3GB has an issue: it cannot detect vram, so can't work as expected. I measured resistance at the PCIe 6 pin connector as you did, and while two grounds are ok, the center ground measures 92.4 kilo ohm. Could this be the issue? What is solution? I can't trace the path, i lose it. Can i short the three grounds together for testing purpose? Is it safe?
Please answer, when laptop detected show error 43, but after disable enable working properly but still not show on task manager, one inductor, mosfet, mosfet driver on vrm was remove because shorted high side
The so-called "mining adapters" are risers/extenders commonly used in cryptomining setups, where multiple GPUs are connected to one system in order to solve cryptographic hashes as fast as possible. As you usually cannot plug more than at most two GPUs into the PCI-e slots on a motherboard, these adapters are used to mount the GPUs somewhere else, even externally to the case. As PCI-e bandwith isn't a big issue when doing cryptomining, these adapters usually have a full (16-lane) PCI-e slot at one end, but just a single-lane PCI-e plug-in adapter at the other. This works because all PCI-e compliant devices are required to function (albeit slower) with only one lane connected. It also means these "mining adapters" are ideal for doing repair work, as you can easily connect any GPU to any PCI-e slot without having to plug it directly into the motherboard. You can even have the GPU running while lying disassembled on the bench, as long as you take reasonable measures to prevent overheating.
Hi sir need help, all voltages getting generated the vcore and vram are up but still no.display no blank display so its not vram could you please guide what should I check to find fault ? Its Rx 580 and rx 560
The lesson is called step by step GPU guide. Todays lesson is what do the shiny gold strips mean. Now I know. Sounds like you already knew. Maybe wait for a later lesson to get to the part you don't know yet

He said point seven five one that's why you misheard him.
It feels like im enrolled into a real class. I educate my self with this kind of stuff coz i want to learn how to repair gpu.
I have one with open circuit on 12v rail. As a beginner looking forward for part two.Thanks.
You`we got my sub and likes from now on sir. This is great material. Thank you.

My Msi rx 570 8gb armor card have no voltage on pex. 0.8 v missing. what should I do?

You are excellent teacher of electronics.
Please do more video about graphics card.
Do you have any telegram channel or WhatsApp?
Awesome!
I have been searching for the video about how the GPU works and couldn't find it! Can you put the link to it in the comments

Hi thanks for the effort but there are faster ways to diagnose.
The lesson is called step by step GPU guide. Todays lesson is what do the shiny gold strips mean. Now I know. Sounds like you already knew.
Maybe wait for a later lesson to get to the part you don't know yet
You didnt check the output coils😉
There are a lot more things to check, This is just the first step and I want to keep the videos down to about 30 mins each, Wait for part 2.
I love your videos Good work

Hairy fingers 🤣
Cant deal with all these adverts its just got silly now
What ads
Personally I don't call that a graphic card, I call that a door stop 😹
