i have an f* load of old and broken gfx cards and mobos... some of them i can even see exploded capacitors and fuses... the problem is i wouldn't know chips to replace them with so they have been sitting in a box collecting dust... i love watching this kind of videos... it really changes the fate of those parts and preventing them from being discarded due to premature failures...
Cool. Im returning mine, I got RX460 windforce 4GB. Fans work at 100% from the boot, and doesn’t disable after boot. Don’t give video signal on the HDMI port and it’s not recognised by windows or the bios which one was the problem with your GPU?
I am using an old Fluke Multimeter the cheapest multi-meter with a speaker will work its best to have needle pointed probes. For the Heat gun, I use Quick 681DW its best to use an under heater on some of these cards they absorb so much heat.
Damn it those ICs are hard to pull off, but did it eventually, thats a great video man! I bought all those tools and watched this for like 20 times and tested on some junk PCBs before the real deal. Thanks, my RX470 owe you its life 😅
hello nice video i had similar problem 2 fuses blowned and one mosfet out but it was the 3rd one from buttom i had to take 2 to find the culprit......i resolder the good one back , my question is is there any replacement mosfet for these one ? also i am having difficulty to read the part # of these mosfet ( wich one you put ) thanks
Thanks have a card here with the same issue removed one of the MOSFET IR3553 now the short is gone going to order a pack of 5 IR3553 so I have some spares.
Great work man. So far managed to repair 2 this way. I do have a problem with some stubborn capacitors that are reeeeaaallly hard to remove. What soldering iron do you recommend for easy removal, 100W 150W?
i only use goot 60w original solder replace solder tips with custom or i use hakko solder with T12-C4 if u have a hard solder with caps ussually i use hot air and solder together it will easy to remove it
Hello! I had an RX470, it was working normally until one fine day it didn't show up anymore. When it first started it was still up and then there was a whistling in the choke (I think). I changed PSU, applied thermal paste. Each time it boots up only 20s then not up anymore. Can you guess what is wrong with it?
i currently have a xfx rx580 that wont detect. good little vid. mine just wont get recognised by board or disp[lay anything, but the chip gets hot quick. so at least I know its not 100% dead
Have you ever had the little 2x2mm AZY chip gone bad? I have one thats heating up and the powerdelivery doesnt work. All Fets and capacitors are fine... Really odd failure point but I can not find what that chip is
I'm doing the same and i just cannot get the VRMs to desolder. I'm using a Weller hot air pencil and also soldering iron to provide more local heat and the VRM is solid! What temperatures and hot air gun are you using? I had the hot air on at 400C for 15 mins before adding the iron to the IC at 450C and only managed to melt the exposed solder pads, the chip is solid.
What if nothing's shorted, yet still no power to gpu/vram. All 3v 5v 12v is there, but no 0.8v-1v on mosfet low side. Btw, ever replace vram chip? It'll be helpful if you can make a video how to detect which vram chip is bad and show replacement process. Great channel, very straightforward and easy to follow.
it sad me got cheap ex mining card rx 470, run for about 1 month, and then dead..want to repair my self, can't found schematics...the component will take month if really exist
Thanks I have a similar card Nitro RX570 8gb it's has the same problem as in this video I have tested the 4 small white fuses on the card and same 2 fuses are blown on my card. I am a complete novice at soldering I've ordered a 3 in one 1 reflow station from eBay and some replacement fuses. Is there any tips you could give me like what temp to run the hot air gun at to remove fuses I've got your video playing on 49inch TV help me see what your doing a bit better I'm very thankful you uploaded this video there is not much documentation on fixing these GPUs.
analog hot air use : -Heat : 4.5 (310c-330c) -air : 4 digital hot air use : -heat : 330c-360c -air : 75-85 all depend on brand reflow station, you can test with a scrap card first
@@Zettabitlab Thanks I have a couple old 512mb low profile cards I plan on testing with I managed to find the fuses on ebay exact same I'm hoping no components are broken and just the fuses. Yihua 853D is the model of the hot air station I ordered hoping it will do the trick. Your very talented keep up the good work thanks for getting back to me.
@@FHP2395 been good upto now done the job currently managed to fix a couple GPUs using it not a bad station for the price soldering iron feels a bit cheap but for the price it's a bargain for begineers like me.
@@HackingVision I'm an absolute beginner. Been watching repair videos this past week and the whole process looks really interesting. Hopefully the Yihua will get me started. Currently on offer where I'm located: www.amazon.co.uk/YiHua-Soldering-Station-Rework-Supply/dp/B07K1HCLSF Congrats on the two GPUs you've already fixed. My first project recently arrived, a GTX 970. If it is okay with you could you help me diagnose the problem. I lose display when under load. The card is fine otherwise.
Hi there, I have found that my sapphire rx480 nitro+ has the same issue but with more mosfets to be repaced. You show that after replacing those mosfets the graphic card came alive, good. But what if the problems is just not only on the mosfets and fuses. What would be the next step to your troubleshoot? Thank you for your great video!!!
André Moreira check the mosfet driver IC if you still have no GPU power. Check if there are more shorts on the board. Honestly it's simply electronic stuff. Check for power and PowerEN signals. If all is good try flash the bios. If you still have no picture your GPU could be bad.
so my r9 290 has the same issue and 3 mosfets are shorted. looking in ebay i can find 3553m mosfets(same as my card uses) but the other numbers do not line up. is it safe to use other 3553 mosfets to replace the dead ones or do the replacements have to be exactly the same as the dead ones ?
Hello, I have 2 rx 480 with the R47 choke broken, I've been looking for this choke for months and I can't find it anywhere... Do you know where I can buy it or get it? Thanks bro
How did you find all the information on what to check on each component and do you use the gpu's diagram or anything like that? Or are the names of the components written on the components themselves and then check what power should go through where or anything like that?
The GPU card itself is build like a little town. Any manufacturer needs to follow amd so on any card MOSFET is used for power stage.. To repair first check fuse the power and so on.. The info for the mosefet is found via Google and the part number is printed in them so..
is it usually No1 that blows because it is closer to the power in and the others have some resistance in the longer tracks? Any advantage to adding more mosfets in the gaps where components are missing? Any idea why this blew? We are thinking ours blew as we were trying to run 5x 4gb cards on one 650W PSU voltage probably dropped and current spiked.
Hi, I have Palit 3080 Gaming Pro 10GB. I wrongly connected +12V to speed signal of double fan socket and GPU died. Now motherboard don't detect GPU. But single fan and RGB LED works when power up.

Hello, my graphics card is recognized and works just fine but only through dvi ports, monitor doesn't detect signal on hdmi and displayport outputs. How can I fix this??
I've got two broken HD 7970's but I can only find two fuses (smaller than those in the video), seems to be no fuses for the external PCI-E power connections. The MOSFET's seem to be of another type aswell, don't know how to measure them. Do you have any good advice for me?
Im repairing my dead r9 390 nitro, the vrm for the memory controller died and i've been trying to get the 3553m out for a while now with my hot air station but it wont budge. Should I warm the board up first? any hep would be greatly appreciated.
Bought a defective palit gt 740 1gb gddr5 worth 4 dollars and when I powered it up no display fan is spinning but when I connect the vga to onboard it has display it seems the gpu is not detected even in the bios. I tried heating the chip but no luck
Dirt can stick to the flux that remains. Also the flux can conduct a bit of current but only with high voltages. It is just good practice to clean it off.
Hi, i have a problem with a MIS ARMOR 8GB OC RX580, the fans are not working properly, i bought replacements and they have the same problem, they work for a while and then stop working, apart from that the card performs very good, tried multiple drivers old and new, if i take out the card for a couple of days it will work again, then the fans stop after 10 or 20 min of use, no matter the temp of the GPU the fans will not spin not even at startup, i have the stock Vbios, this card is used dunno if it was a minning card or not, i was wondering if maybe there is a resistance or something that controls de power going to the fans, it allways work i can use it normally and it will remain at 60 deg C, unless i start a game, any ideas what can it be? Thanks !
Hi, I have an XFX 470 8GB which has display runs youtube videos even at 4k..but when i start a game it crashes/artifacts...tried with new bios other pc/drivers...could be a hi-mosfet which fails to deliver enough power to the chip when required?
can u identify the problem? my GPU is RX 470 Sapphire Platinum Edition PCIE wont detect the GPU but the fan is running and i can feel some heat in the procesor my Motherboard is MSI A68HM E33 V2 please reply :')
Yes as it is only transistor type model MOSFET... The different numbers i s week the where made or batch number. Model needs to be same so IR3553M is a must any time!
I have a Sapphire RX 480 nitro+ that I believe has blown a fuse. Could you please tell what part# for the fuses? Or maybe what kind of fuse and how many amps they are. I've been searching the net but can't find any info. I just not sure what I'm looking for.
hello, I have a problem, I have replaced the mosfet and the VGA runs normally, after my PC turns off and on, the fuse blows and the mosfet is short, what is the cause? thank you 
Hello there, great repair, i want to ask.. step first in ic FUSE from power normal, and step second fuse from pcie power pin psu normal, and the last step i check the mosfet is short/broken vin and ground connected like a video, maybe because the mosfet is short make the gpu is not working/no detect? i want to repair in home
hello i have three AMD sapphire HD6990 4gb Dual gpu, one is shorted to ground so how can i know wich mosfet is bad if all mosfet make buzzer when test them any idea?? second fan turn but gpu cold with no display 3rd fan spin gpu hot no display best regards
I’ve got an rx480 that gives picture before installing Radeon drivers. After drivers load it black screens. I feel it gets really hot around the mosfet area. Where do i start the diagnosis?
Hi.. I have an asus rx470 4gb mining card that used to work then it suddenly shut down.. but after turning it off and turned it back on the card just lights blinks for less than a second and the fans just barely moves. I know its not a fuse issue but maybe on another component that might be shorted. Can you point me in the right direction? thank you
Bruh, so I had my asus rx580 sent to warranty for repair. And now it is crashing, 0 OC potential (I have to underclock for playing) and they said that it is working. I added some heatsinks on the vrm and only then I can play. The vrm was originaly bad, they've replaced 3 mosfets. It has 6 phases, I think that just half are working. When I play demanding games the vrm skyrocket to 90-120°C. What should I do?
Nice job fixing that GPU man, keep it up. I have some questions about fixing GPUs. A friend of mine had a GTX 750 Ti, but one day he had a blackout at home. When he tried to turn on the PC, it didn't display any signal, so he bought another GPU and I asked him to give me his 750. After a couple of tests I've noticed that the GPU actually works because the PC starts up withouth problems, but there is not signal. I really want to fix it because where I live the components are too expensive. Do you have any clue of what could it be? Checking the back of the card I noticed that there is a resistor that has a black dot in the middle. Could it be the problem? I'd like to show you some pics of it.
Hello,my old ati radeon hd 4890 has black screen problem,tried cleaning it to the maximum,but still nothing,and the core is hot to the touch,so its getting power,what could be the problem in this case?it doesnt even want to boot or even show bios or any signs of life Best regards
Nice video great job my friend!!! Let me ask you regarding a quadro fx3700, its temperature is really high during web-browsing and when i test it with heaven benchmark its temperature exceeds 110 celsius and the dsplay freezes. What would you suggest?
Sorry to ask. If the GPU is not used for normal game play even for hours, but when it is used to play games for 5-10 minutes, the direct view does not appear (no display) what is the cause?
CoRE- Fixpc so you started from the 1st phase and moved on If it weren't the right one you would remove the 2nd phase MOSFET and so on? I've watched the video again and again. And i got one more question... What if the power line is shorted to ground by other component like ceramic capacities!
Hi my quadro m4000 burnt somewhere near the display port 1,it doesnt boot nor it use to detect before smelling bad and stopped working all together.Although gpu fan works,second attempt to boot caused it to spin really high with a noise of fan. There are power fluctuations,probably power fluctuation caused it.i can share you the pics on email if u can !!!

Look for the numbers on top of the MOSFET search them and it will tell you what is ground gate and drain

how do you check if it's just the vram went bad or the other components like these?
what caused this?, was it an overclock that possibly caused this?

Hi, I have an XFX 470 8GB which has display runs youtube videos even at 4k..but when i start a game it crashes/artifacts...tried with new bios other pc/drivers...could be a hi-mosfet which fails to deliver enough power to the chip when required?
can u identify the problem?
my GPU is RX 470 Sapphire Platinum Edition
PCIE wont detect the GPU but the fan is running and i can feel some heat in the procesor
my Motherboard is MSI A68HM E33 V2
please reply :')
Hi! Is any of IR3553M drivers are good for replacing the broken one? i've found only IR3553M drivers with different numbers on it.
Yes as it is only transistor type model MOSFET... The different numbers i s week the where made or batch number. Model needs to be same so IR3553M is a must any time!
I want to ask, a gtx 1050ti that died still repairable??
sir, how to do you which is the mosfet no1, no2, no3 , no4 , no5 ?
good schooling on the gpuz man learned somethings
I have a Sapphire RX 480 nitro+ that I believe has blown a fuse. Could you please tell what part# for the fuses? Or maybe what kind of fuse and how many amps they are. I've been searching the net but can't find any info.
I just not sure what I'm looking for.
just browse "smd fuse 10A 1808"
look at top mark ic, if 10 = 10A , 05=5A
@@Zettabitlab Thank you.
hello, I have a problem, I have replaced the mosfet and the VGA runs normally, after my PC turns off and on, the fuse blows and the mosfet is short, what is the cause? thank you

Check another mosfet,
Hello there, great repair, i want to ask.. step first in ic FUSE from power normal, and step second fuse from pcie power pin psu normal, and the last step i check the mosfet is short/broken vin and ground connected like a video, maybe because the mosfet is short make the gpu is not working/no detect? i want to repair in home
iya mas, mosfet biasanya short.coba dicopot aja trus diukur ulang.
@@Zettabitlab oalah dari indonesia ternyata, buka jasa perbaiki ga mas?
@@ekasapta8185 sudah engga lg mas.lg rencana mau buka tahun dpn.
dari jogja sy mas.

how do you know ..that mosfet short..only guessing or what..please tell me sir..i want to learn about service vga
hello i have three AMD sapphire HD6990 4gb Dual gpu, one is shorted to ground so how can i know wich mosfet is bad if all mosfet make buzzer when test them any idea??
second fan turn but gpu cold with no display
3rd fan spin gpu hot no display
best regards
I’ve got an rx480 that gives picture before installing Radeon drivers. After drivers load it black screens. I feel it gets really hot around the mosfet area. Where do i start the diagnosis?
what if all voltage is present? but still nothing?
dead chip.
Dead chip or corrupt video bios
Hi.. I have an asus rx470 4gb mining card that used to work then it suddenly shut down.. but after turning it off and turned it back on the card just lights blinks for less than a second and the fans just barely moves. I know its not a fuse issue but maybe on another component that might be shorted. Can you point me in the right direction? thank you
Bruh, so I had my asus rx580 sent to warranty for repair. And now it is crashing, 0 OC potential (I have to underclock for playing) and they said that it is working. I added some heatsinks on the vrm and only then I can play. The vrm was originaly bad, they've replaced 3 mosfets. It has 6 phases, I think that just half are working. When I play demanding games the vrm skyrocket to 90-120°C. What should I do?
Nice job fixing that GPU man, keep it up. I have some questions about fixing GPUs.
A friend of mine had a GTX 750 Ti, but one day he had a blackout at home. When he tried to turn on the PC, it didn't display any signal, so he bought another GPU and I asked him to give me his 750. After a couple of tests I've noticed that the GPU actually works because the PC starts up withouth problems, but there is not signal. I really want to fix it because where I live the components are too expensive. Do you have any clue of what could it be? Checking the back of the card I noticed that there is a resistor that has a black dot in the middle. Could it be the problem? I'd like to show you some pics of it.
probably too late but,
He bricked the gpu
How much did it cost ?
I mean the repair
Hello,my old ati radeon hd 4890 has black screen problem,tried cleaning it to the maximum,but still nothing,and the core is hot to the touch,so its getting power,what could be the problem in this case?it doesnt even want to boot or even show bios or any signs of life
Best regards
When you say the Ampers was different(for the fuse's) how much the difference was?
backyard studio in rx use 10A fuse, it use 7A , but it just for temporar repair, then i chanhe again buy from alixprs 10a fuse.
does desoldered like that damage other components?
Hi, How do u know which mosfet is number 1?
i have a amd radeon scheme,
@@Zettabitlab thx for answer, on what temp are u setting yout head gun?
@@marcel8362 360c, do not higher than that.
@@Zettabitlab thanks, because I have the same graphic card and no matter how much heat I put, mosfet wont desolder. Mayby u have an idea why
Nice video great job my friend!!! Let me ask you regarding a quadro fx3700, its temperature is really high during web-browsing and when i test it with heaven benchmark its temperature exceeds 110 celsius and the dsplay freezes. What would you suggest?
Did you ever clean up hsf from dust, and change with good paste.
Quadro max temp around 105-110 then it restart or hang.daily used about 70-85c
Thank you for the advic, one last question, what thickness should the thermal pads be? 2mm or 1mm?
@@AlexSBedini thermal pad fir vram, every vendor use 2mm thickness. But depend on space between hsf and vram/mosfet.
love this video
where i can buy the mosfet and the fuse?
Sorry to ask. If the GPU is not used for normal game play even for hours, but when it is used to play games for 5-10 minutes, the direct view does not appear (no display) what is the cause?
You nailed it dude!! High 5
What is the table material? I'm looking to do this at home but wouldn't do it on wood.
I've considered marble, but that shit's expensive.
Antistatic ,from onglai tools
@@Zettabitlab Thanks!
Can you fix gtx650Ti? only one fan spins. No post/display.
This is amazing bro. Could we contact you for help to fix our gpus?
same here
How did you know the right one of the MOSFET to remove in The power rails?
same question
the simple one is you must know where's first phase is...
CoRE- Fixpc so you started from the 1st phase and moved on
If it weren't the right one you would remove the 2nd phase MOSFET and so on?
I've watched the video again and again.
And i got one more question...
What if the power line is shorted to ground by other component like ceramic capacities!
Hi my quadro m4000 burnt somewhere near the display port 1,it doesnt boot nor it use to detect before smelling bad and stopped working all together.Although gpu fan works,second attempt to boot caused it to spin really high with a noise of fan. There are power fluctuations,probably power fluctuation caused it.i can share you the pics on email if u can !!!
do you know how to fix Lucky Strike?
How much do you charge to fix out of warranty video cards, or video cards with difficult no second hand warranty?
service charge depend on graphics card series, usually about 30% from second hand price.
What if the card has no fuses?
dude, where to learn this ?, like figuring how each component corresponding and working
i learn autodidac, from experience and read scheme.
bro i have msi gtx 970 i have this same issue ...can u help me?
Mosfetnya ir3553 ada sisa mas? Boleh saya beli? Nunggu dari cina lama mas hehe
hey, I have the same problem but my card is a 1050ti so it has no pcie power connector any fixes ?
Please help me, I have a gtx Titan X, long story but no post, it has this black/grey goo around one of the memory chips and some of the pins were corroded(I cleaned them off) but what is this goo? I don't want to plug it in incase it ruins something
I have a gtx 970 shows power down the gpu and connect to power adapter but it is already connected and if I plug my gtx 1080 it work normal is there any solution.
