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?
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
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’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?
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.
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.
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
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??
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 !
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
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?
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?
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?
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
Can someone help me? I am newbie. when i put the upper vrm the rest of vrm shorts but when i put it out it doesn't short anymore. what could possibly the culprit here? or did I solder it wrong like the lead sticks with other lead.
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
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.
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.. 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
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?
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.
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 :')
MY gpu seems to be working fine after reheating it using hair dryer for 30 mins but after 2-3 days of using while gaming, it shows green lines flickers and sometimes it doesnt display or the pc reboots after it crashes while playing. Why is that happening?
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.
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.

Zettabit. lab can you please help me... i have hd7770 that stopped working hdmi and DVI ports after i used bad hdmi cable for half minute...but displayport still working... i measure voltages on HDMI pins and DVI pins on cable end from gpu and i get 5volts on hdmi pin 18 and dvi pin 14... but on hdmi pins 15,16 i get sometimes 1,42v sometimes close to 2v and same on pins 22 and 23 on DVI where supposed to be 5v what should be problem?
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..
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'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.

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
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
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.
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
Hi, my rx460 has a bad fuse marked for 10A, I only was able to scavenge the one from dead xbox 360 but it is black and marked for 9. would it do the job ? Is it safe to make jump connection for a while ? I would be thankful for reply
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 
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.

Hola, tengo una rx570 no da video ni calienta el chip de video, ni gira el cooler, ni windows lo reconoce. Podra ser el BIOS?
what caused this?, was it an overclock that possibly caused this?
У меня на плате rx470 отсутствует элемент q201 шестиножка. Находится там где разъем куллера с другой стороны. Подскажите, пожалуйста, что это?
Nice video by the way ,really nice.I do diy soldering using heat gun and micro soldering.i wish u can help...
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
I want to ask, a gtx 1050ti that died still repairable??
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.
My gpu is rx 560 4gb oc. My grpu no display and no fan spinning. But i check gpu cheap set heat. So what's the problem..?
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
same :(
What is the detail
type of the fuse.. it stated 10A..
Hi, my rx460 has a bad fuse marked for 10A, I only was able to scavenge the one from dead xbox 360 but it is black and marked for 9. would it do the job ? Is it safe to make jump connection for a while ? I would be thankful for reply
put in the 9A one, no fuse means you blow up the card in case of a surge
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,
If you have to replace parts, how do you get them? Which online shop?
Bli Gm , sometimes i use from another card scrab if not i buy from alixpres. Just looking for good seller reputation.
hi man. how about smd capacitors? are they easy to replace? mine card is missing 4 of them i get black screen and beeps from motherboard
Državljanin Banana Republike smd caps it's easy to take off from pcb. Use hot air or double tips soldering iron.

Keren bro
Hi and goomorning my rx570nitro+ 8gb sapphire is brick after mod for mining ....where find this tools ?
mantap lur. 😘. apa tipe mosfet dan fuse nya? apa sama dengan RX580 sapphire nitro?
how do you know ..that mosfet short..only guessing or what..please tell me sir..i want to learn about service vga
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.
@@Todestelzer so, sent the board to an electronic laboratory, and the GPU chip died... Thanks for video.
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.
