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.
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
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 😅
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..
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?
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
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
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 ?
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.
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.
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?
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.
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.
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??
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!
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.
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.
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

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 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
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.
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!
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
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.
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 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. I discovered the GPU. It has one Holtek HT50F52241 and one IS25WP080 and others. Your opinion, which chip controls fans? and which begins communication with motherboard? May my mistake damage main GPU chip? Do i hope that repair it? Please answer me. Thanks for videos.
i overclocked it once or twice but even before that it still crashes with mix colored screen. my gpu is sapphire rx 470 and its in auto OC. i tried looking on the pcb, some was dirty and some corroded. then i clean it THOROUGHLY with iso alchohol then dried in on the sun then it worked fine for a few days. then all of the sudden, it started crashing again. LOL i have this feeling that every time that i dont use the gpu for a month or so, it will work for a few weeks or days. i have this problem for over a year now. hehe and im using the gpu right now. LOL
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
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.
i removed that component from the board and it was in short when i measured it outside but the card still has another short circuit, what do you suggest ? remove the remaining mosfets one by one until the short is gone ?
exact same model, RX 470 nitro plus 8 gb, do you have whats app ? i'm so sad i really need help :( , also which mosfet you want me to remove next the top from which side ?
do you mean the one to the side of the PCI-E 8 pin power connector or the opposite side ? i'm not sure what you mean by the "top one" cause it depends on how you are holding the board
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?
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?
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?
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?

Hi, I have a RX470 4GB MINING Edition card, and I've noticed that the only HDMI port, doesn't have most of it's resistors (the tiny small rectangular components). Would you advise where I could buy them ? (card has no waranty, let's say).
Can I just bother you with one more reply? What would the names of those components be? (just after the HDMI port, there is a cluster of resistors, can't identify them).
which one, tiny black is resistor, grey is capasitor, tiny three leg is transistor or u can use marking code on the board, L = fuse , R = resistor, C= capasitor, Q= diode

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.
sir, how to do you which is the mosfet no1, no2, no3 , no4 , no5 ?
Help.. My sapphire nitro+ rx580 all work fine except FAN and RGB no longer work.
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
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!
I have a 3090 that I'm having issues with. Can you refer me to someone that can work on it or is it something you would be interested to work on?
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.
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
Any luck? Palit cards are just bad, my palit gtx1060 has the same issue. Never buying palit cards again.
bro i have msi gtx 970 i have this same issue ...can u help me?
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.
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?
Sir what temperature did u use?
I want to ask, a gtx 1050ti that died still repairable??
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.
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.
I discovered the GPU. It has one Holtek HT50F52241 and one IS25WP080 and others.
Your opinion, which chip controls fans? and which begins communication with motherboard?
May my mistake damage main GPU chip?
Do i hope that repair it?
Please answer me.
Thanks for videos.
need ur help. have u ever encountered graphic cards crashing and leaving a blank colored screen. different colors everytime. is ther a way to fix it?
Reinier John there's a rgb spot broken on gpu, try to reflow it with bga rework. Whatbis your card series?
CoRE- Fixpc everything works sometimes. the fan check on trixx shows the fan not working but it works fine.
Have you over clocked? This happens with a too high clock.
@@sshep86 nope, set default clock.
i overclocked it once or twice but even before that it still crashes with mix colored screen. my gpu is sapphire rx 470 and its in auto OC. i tried looking on the pcb, some was dirty and some corroded. then i clean it THOROUGHLY with iso alchohol then dried in on the sun then it worked fine for a few days. then all of the sudden, it started crashing again. LOL
i have this feeling that every time that i dont use the gpu for a month or so, it will work for a few weeks or days. i have this problem for over a year now. hehe and im using the gpu right now. LOL
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
У меня на плате rx470 отсутствует элемент q201 шестиножка. Находится там где разъем куллера с другой стороны. Подскажите, пожалуйста, что это?
Now I getting 6600xt powercolor problem same problem no detect/ no working. If you have some idea please advice
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
my nvidia 1050ti not displaying sudenly but its processor is heating while running but not displaying what u think ?
i removed that component from the board and it was in short when i measured it outside but the card still has another short circuit, what do you suggest ? remove the remaining mosfets one by one until the short is gone ?
Is your card same like this. Check for another fet, ussualy at top one.
exact same model, RX 470 nitro plus 8 gb, do you have whats app ? i'm so sad i really need help :( , also which mosfet you want me to remove next the top from which side ?
can you please help me sir :(
@@JR-ob7hz yap. Did you already check on the top one..
do you mean the one to the side of the PCI-E 8 pin power connector or the opposite side ? i'm not sure what you mean by the "top one" cause it depends on how you are holding the board
What could cause that? Overvolting for overlclocking or bad PSU?
bad psu, buy a good one with a good voltage regulator.
Or component failure might cause it too.
But it seems to be overclocking problem.
this happens mostly trying to overclock without knowledge of voltages, also a random bad generic psu without
security capabilities
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?
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.
Thanks Dude...a thousand Times. Had the same issue.
How much did it cost ?
I mean the repair
What is the detail
type of the fuse.. it stated 10A..
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?
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?
What Temp you use for the heat gun ?
360c
how do you know ..that mosfet short..only guessing or what..please tell me sir..i want to learn about service vga
Hi, i have same rx 470 with same problem. But after i checked like your tutorial, everything seems OK. So, what next step should i do?
gpunya ka,kl memang komponen yg lain tidak ada kendala, bisa di cek bagian capasitor dkt vram, biasanya short disitu
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
Mosfetnya ir3553 ada sisa mas? Boleh saya beli? Nunggu dari cina lama mas hehe

Hi, I have a RX470 4GB MINING Edition card, and I've noticed that the only HDMI port, doesn't have most of it's resistors (the tiny small rectangular components).
Would you advise where I could buy them ? (card has no waranty, let's say).
i always buy from ebay or aliexpres, it's a trusted to shop international
Can I just bother you with one more reply? What would the names of those components be? (just after the HDMI port, there is a cluster of resistors, can't identify them).
which one, tiny black is resistor, grey is capasitor, tiny three leg is transistor
or u can use marking code on the board, L = fuse , R = resistor, C= capasitor, Q= diode
it says R1810, has to be resistor.
yes it is. usually with value 10-100ohm
Hey i got one of these and its been relfashed and still will not work no matter what bios is on it. Any ideas.what to try?
do you offer repair service?
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.

From 4‘15“, the VIN test， there are 3 MOSFETs beep, how do you decide to replace the one in the middle?
I believe he removed it, tested again, heard no beep and so he concluded that was the one that needed to be replaced?
inject 1 v to 12 v input. and touch the mosfet. the warm one is the short mosfet
@@ariewijaya1679 What part of 12v input, can you explain more?
@@euphoricmonkinject 1v to 12v pcie 8 pin power
@@ariewijaya1679ok, I only have 1.2v injector. So ground and 1.2v to 12v pin? and check for hot mosfet?
