Found this channel today and feel like I just stumbled across a gold mine

You gained a sub and like brother, obviously a comment too. Really happy I found your channel. I have been doing PC repairs for years but self taught. I learned alot and will be watching more of your content. Thanks again keep it up

This is the best tutorial on KZfaq by far. Very clear informative guidance. Thank you

30 min of video but i won't mind if it lasted 60 min. Thanks very much for the info. You earn a subscriber. would love to see more content like this.

16:45 is what i was watching this video for. I had hoped i could diagnose my artifact issue more, as i got unlucky with a 2nd hand GPU purchase (ex mining card). I have a micrometer, heat gun, and soldering iron already luckily. Just can't be bothered to spend more money buying new memory on this GPU. Think i'm going to heatgun it and hopefully get a bit of life out of it. Great videos btw. Have subbed as very educational!

Thank you bro I needed help with my graphic idk why it’s not showing any signal now I know how to use the power multimeter

Thank you so much for doing this. I now have the confidence to repair my 1070ti GPU. Thanks again for the clear precise diagnostics.

Geile Nummer, wirklich gut erklärt und bin begeistert wo Du dir das alles her geholt hast. Es ist wirklich schwer infos zu bekommen.Danke

Thank you for your help and explanations on how to repair and how to use multimeter!

This video is a gem..thank you so much for this💓

Finally found a video of how to check GPU with multimeter! Thank you!!! :)

I love your stuff. Nice and detailed. Thanks!

Crazy amount of great information! Liked and subbed my friend🍻

You're German? Danke für das Video habe soooo verzweifelt nach so etwas gesucht, sogar auf englisch. Dein Kanal ist eine echte Goldgrube!!!

officially subscribed, we have the same mousepad, ty for the lesson man :D

you should make more of these videos, the quality is great compared to what is out there

Thanks for this very informative video. Makes me want to open my burnt gtx 980 ti and try to repair it. Greetings from Manila, Philippines.

30 minutes of your video gave me more knoweledge than the teachers did in my electro specialised high school. Well done and thank you👍🏻

Your the best! Been looking for repair data on GpUs! I have a few cards that have different symptoms of failure. Will be using your instructional videos to trouble shoot and repair. Question: what is the best way to contact you to discuss details if I run into a snag?

just love this guy

excellent video friend congratulations few people do what you do share the knowledge I congratulate you and thank you and if you can make a video no matter how many minutes you explain the starting sequence of each graph it would be of great help

Thank you. This is a very helpful video.

Wow 😀 thanks danke obrigado shukriya Needed this badly 🙌

Hello, nice and informative video, what to measure for when GPU shows image on boot screen, but after that it goes black while system still works. Thank you.

Really informative. Could you please make a video about artifacts. And reballing the main gpu. With all this information, the one can start repairing dead GPUs.

Thank you so much for your effort.

Hello thank you for these super videos. I have an issue with my 1080 ti gigabyte. Fans running led too, but no pic on the screen and card not detected, the core temp increase when i put my thumb on it, there is no burned component and i made a lot of measurements, but I don't know if what i measure is in the good range :( Any advice for this kind of problem ? Best regards Silas

Well done, sir!!!

Thank you very much for the video

Very helpful thank you ❤️🙏

underrated channel

This was a great vid idea

Hi @Zoras Tech, please also make a guide on how to identify which are the Bios chip, 1.5v chip, 1.8v chip, pex rail etc. This is the best video ever!

Hi, I loved your videos, lots of information there.... So, recently i got a broken Zotac GTX 750 wich have odd behavior. the card didn't show anything on display monitor (no display), but VRM's voltages on GPU and Memory are present, wich are 0.9 v and 1.5 v (indicating VRMs are work, isn't?). The gpu get hot when i turn the PC. When i probing resistance between PCIe's 12V rail and ground, it was too high, around 1,7k Ohm ( other working GTX 750 with same PCB has 600-700 Ohms). But interestingly, when i flip the probe (red on ground and black on Caps near 12v pin) the resistance are same with working one, around 400 ohms. it's seems like a faulty diode, right? or another component can causing this too? thanks....

Can you do a video about repairing a short inside a multi-layer PCB? For example, when a mosfet melts down and burns a hole through the PCB, bridging the ground plane with the 12v plane.

great video, I have RX580 4GB that has default 1750Mhz on mem but when I run unigene heaven it just crash then blackscreen. Tried to downclock the mem to 1500Mhz and it run 20 minutes of unigene heaven just fine. Is this case of degraded vram?

Thank you so much for the fast replay for my previous question. let me ask you another related question. i am thinking to turn on the card using only power supply and riser (No Motherboard) , i will connect the pcie power to card and raiser power and jumper the motherboard power connector pins 3+4 , i assume this will turn on the card and i will be able to measure all voltage rails. what do you think ?

hello and thank you so much for this valuable information. in minute 25:39 you mentioned that you turn the card on and start measuring different volts on the card. this is ok if the main chip is not getting hot , but in some case the card is not detectable but the main chip start to get hot and the card is naked (lol this make sense) so what you will do in this case , for how long you can keep the card without heatsink and fans while measuring the volts specially you need to measure in different places in the card in front and in the back ????!!!

Finally after many months,another tutorial on gpu tutorials❤️❤️

You think the bios chip or memory could be the culprit when the GPU isn't recognized in the device manager and the resolution refuses to go past 1024x768? If I try to go past 1024 x 768, the screen artifacts.

Hi, I would like to know if dried flux must be cleaned in order to get good reads? Because as far as I know, flux isn't electrically conductive. Danke schoen!

hey guys i have a gpu that had a blown fuse(f10a), i replaced it with a 12 amp fuse(f12a) and now the motherboard is powering on again but i still dont have video output and the fans are not spinning, however when i turn on the motherboard i do see a very tiny spin in the gpu fans so something is happening. How would i go about and diagnosing this? help is much appriciated guys much love!

The fuse of my Gigabyte GTX 760OC is blown. Is there anywhere you can find shedules of these cards to know what type of the fuse it is?

how do you figure out which is the pex (not sure if spelling is correct) which is the 5 volt and all the minor rail? how do you identify them and where to stab them to find short?

I saw the Stabbing Guide title and was expecting an Alfred Hitchcock presents presentation.

How do you know what's a normal resistance ? I've got a 5600xt water dammged been watching so many vids trying to figure out how to test it lol I've got as far as testing the main powers not shorted that's it lol

I need more videos like this ... What about shorted gpu and some missing part from gpu , i have 4 shorted HD6990 How to figure out and fix the problem

i have buzz in vram capacitors on my sapphire nitro+ rx470 , how to remove this short circuit , help me please

Hi i am a newbee, i have a problem and i hope you can point me to the right direction. I have this video card Gigabyte GTX 1070 Ti 8 GB BIOS (GV-N107TGAMING-8GD) And what happened is that he recognise the card but I get no bios screen, the screen lights a bit but overall a black screen. I have already check memory with mods and they seems to be ok. other suggestions please?

When you are trying to measure voltages for reference, is it a good practice to have the card out and power the 12 volt plugs with a power supply? Would this be of any help in checking a board? If you put it in the computer and power it up, wouldn't the cpu start heating up right away so that you could not leave it on without a fan and heat-sink long enough to check voltages? I just subscribed, have you done a video card repair from the start showing what to check and why first and what you would expect to see and why? I have been looking for a channel that shows this with explanations as you seem to hear. I have purchased several broken cheap video cards trying to learn repair without any luck yet. 4 more boards to try to figure out coming next week! Thanks for the video and its content. Stay safe and well in these times.

Zoras i found shorted mosfet on my gpu and removed it. But i didn't replace that mosfet with new one. My gpu back to life(installed driver and played some games etc.) After a week the gpu dead again. Lights on and fans are spinning but no display. Gpu chip is do not get warm also. Do i have vrm problem again? Or gpu is totally dead?

I try to measure GTX 750ti's vmem resistance is 500 milli ohms ( too low resistance which is normally 50 ohms). Is the vmem short ?

bro I have aasus gtx 1060 strix 6gb card . .it doesnt detect by any motherboard... how can i troubleshoot this..

Much Better Do It Straight To The Point!

Hello sir do you have zotac GTX 960 4gb schematic, of yes it would help me a lot l, i got a burnt GTX 960 some components burnt off.

Hi. Great video. Please can someone tell me what could be wrong in gpu crashes under heavy load. Gpu is not overheating. If I undervolt it than it a little better but also restarts randomly. Power supply is 750w. Gpu is rx470 and rx580. Thanks

Do you accept repair jobs? I have an Asic compute board that had (6) chips come off attached to their heat sinks.

How do you do same to gaming laptop GPU ?

Hi, thank you for the video, i have a 12v(of the pci-e) to ground short , where could the problem be located??

how about using thermal camera and plug in power to check which component overheat fast and solve the problem ? or is it still better to use multimeter ?

My 3090(strix) won't power on while in my pc. My pc shutdown while playing Cold War. It gets red lights on the pcie power ports if plugged into the mobo, but pc will not power in if I plug the power cables into the gpu. My PC will turn on with a 2070 super installed though🧐.

Hello, My GTX 1070 broke and I think it might need a chip :(. Anyone knows how or where can I get it? Thank you.

Alternative Title: Repairing in London

Is there a database or sth where we can found all of the nominal core resistances for different card gens listed?

Very good video. I have rtx 3070 my windows can't detect it at all and in device manager it not appear . Is that ok if i send to you this vga by dhl and you repair it for me and i pay all shipping and repairing cost. Waiting your reply Thank you

You will get the correct impedance by putting your red probe to ground and continue testing impedance with black probe.

omg thx so much

can you damage anything wile in resistance mode on 200, if you touch the wrong point on a gpu?

Dear friend,i start recently to repair graphic card,and i have a r9 390 with 20 ohms rezistence on 3,3volt it means i have a bad gpu? or is possible to find something else defect Thank you

I have a 970 and it works but it won't boost and it will stay at low clocks while having 100% usage can anyone help plz

Dear friend, do you make repairs to others or you make it for yourself or schooling, I have one gtx1080ti in box with simptoms of dead memory module, I have no tools and experience to make it alone, I am in Germany in BW and sending with DHL is easy game. Grus

Gibt es dieses Video auch noch mal auf Deutsch? Man versteht es zwar, aber so manches wäre doch schöner auf deutsch. Aber trotzdem danke. :)

Started watching and thought to myself that is German accent isn’t it? Then you said Germany and I knew it!

Do you have a repair guide or schematics for a reference EVGA 980Ti? CIN:4995AI154518. Picked up the card from a friend who said screen suddenly went black while playing, now there's no signal. Should note the card wasn't tampered with in the past. Visual inspection of pcb doesn't reveal any burnt marks. I suspect its a faulty MOSFET, but I'm just beginning to learn how a card works, unfortunately. Cheers:)!

I can post this video on my blog for you if you like its very good video I have a GTX 1060 6GB from Asus I'm trying to fix can't get to the bottom of whats wrong with it.

gtx 950 invalid format on tv how to fix it

8:21 me: realise (was desoldering and remove all capacitors and resistors near the inductor(because i think that is short))

Can I email you abouy my problem if you have time to help me?

This world is so hard to get a gpu i left all my gaming dreams cuz I can't get a gpu .

gofundme to get you a better multimeter

27:46 - "Power it with one of these" What is it ? please, anyone. At least if I know the name I can research it. Thanks for the vid, I now know how and where to measure resistances and voltage on a pcb with a multi meter. Slowly improving my knowledge.

How to know if something is a fuse or just a "shunt resistor" (what's that?)

But still good job

Can I send you a card for repair? From Canada.

yes what do i stab on graphic card hmm

hahahaha stabbing guide

Hey,I just wanted to say thank you for this very in depth video!So,I got an issue with a Sapphire Nitro+ Rx 570,the 4GB edition.The card was originally in my sister's pc for 3 years with not so good of an airflow and she preferred silence so it was running around the thermal threshold while she was gaming.So what this card does is,the screen goes black and i get an audio glitching effect,then it crashes and I get no display signal,but if i leave it off the pc for say like 2 or 3 days and install it again it works for a few days and it starts crashing again.While playing I get no artifacts and the card itself overclocks really well for a 570,If it powers up it can clock up to 1450/1480mhz stable on the core.Temps are in check with custom fan curves and never exceed 55-56C.Could it be a short of some sort or does the die itself need a reball?

In your videos you often mention your other videos but dont put links to them

24:30

Are u elleh tech??

Totally confusing and self confusing types. I got same situation on gtx 1050ti and rtx2060 but I couldn't find a single tips from this video. Only fan spinning with no display after connecting to riser and external psu.
