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!

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?

[@atifservicecenter]

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

[@eatont9999]

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.

[@CmdrSoyo]

I already did a fix like that on a GTX 780 (you can look up the video on the channel page) sadly the card never worked out because of other issues it had

[@geforce5591]

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.

[@justforupload3337]

[@newgame09794]

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?

[@Sarah.Lemontea]

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 ?

[@Dmiliunas]

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.

[@DarkoPetreski]

That's not repairing. You can't repair flip chip GPU's with reflowing or reballing. It's just a temporary fix. But if you can reball a gpu sucessfully you can sucessfully replace a GPU chip.

[@3d4arab]

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 ?

[@CmdrSoyo]

that's how i do it

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!

[@GremaxLP]

You dont have,1, 5V, the bios Chip always has an 25&20 or simular makings on it (kile 25h16 or so) and the most are vrom winbound. In all gpus as far i know, the 1V rail if its there, is on the pcie express Front side near the mem. 1,8V is mostly in the back of the card.

[@mundogamer3006]

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!

[@krisrobitzsch]

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

[@fersaherez2128]

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?

[@amtpdb1]

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.

[@CmdrSoyo]

The card has to be properly powered up to measure voltages. If it is not running and just getting 12V in the power plugs then you will get just that. Only 12V on the power plugs. Everything else will stay turned off. As soon as there is voltage on a part it powers up and gets hot. Not much to do about that except be fast and maybe find something to cool it down for a few more seconds

[@marlontilborg9691]

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?

[@fuzzykeuh]

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?

[@farizfadillah7557]

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....

[@3d4arab]

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 ????!!!

[@CmdrSoyo]

Place a small piece if metal on the core, turn it on and make *one* measurement. Turn it off, let it cool down and repeat

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:)!

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

[@CmdrSoyo]

You know what is what from what they look like. Usually fuses have their amperage rating written on them and the resistors have their resistance written on it that can help. The shunt resistors are used in nvidia's power monitoring system. Buildzoid made a video about how it works exactly

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?
