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...
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 😅
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.
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
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.
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 ?
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
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?
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?
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
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?
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?
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 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 !
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??
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.
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?
Dude, I want to ask something, so my GPU (Strix RX470 4GB) somehow can't be detected by my motherboard (MSI B350M Pro-VH and I also tried changing to ASRock A320M R.4 all bios updated) but it worked just fine on my friend's rig (He got A10 kaveri with ASRock something mobo and VS450 psu) Why is it so? Tried to change my PSU though (From Corsair CX600 2013 to Antec NE550C) and it still doesn't work (no display), it can be detected but very rarely (about 5% chance maybe) and everytime I plug in and replug the HDMI to my GPU, it kinda give my monitor a little feedback (from "no display" to blank screen > searching for output), do you think what could be the problem? I still have local guarantee though about 3 more months, but im not sure if it's the VGA because it works very well on my friend's PC Nice video btw :)
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?
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
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.
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.
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.
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?
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
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..
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.
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
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?
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.
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'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.
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
Sir, i have amd rx 480 8gb gddr5 when i connect 8 pin of smps to the graphic card the 2 fans rotates but when i connect graphic card to the slot on the motherboard fan does not rotates and graphic card is not detected by the computer. Is my graphic card faulty?
Have same card. İ changed mosfet it started work but when start stress test after 1 minute, fps drops and temp drops for a second and its repeating. Whats wrong
Hey! I have a problem with my gpu i.e R7 265 it is not supporting drivers whenever I Install drivers I hear connecting and reconnecting sound and the screen blinks and freezes please can u help me figure out?
Can u help I have a problem my 2 year old gtx 1060 card now showing no display (the connection is hdmi ) I been playing a game and after some time pc went sleep and when I tried to wake it up all started no display on monitor after that I have tried different HDMI cable but not working . Actually graphics card fan is working and it's heating up too like before when connected but no display And my question is does the HDMI port of graphics card broken ? I didnt checked other ports because my monitor only have HDMI and vga port and graphics card have HDMI,dp,dvi ports Is this card dead ? i never overclocked this card and maintained temp under 70c most time what could be the problem monitor or motherboard don't have any problem I checked
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
Can you help me i got a no display gtx 750ti gpu,fan spins ,gpu will get hot,after many continuous reboot i get display can use till i shutdown and repeats.After doing this for 3-4 days now restart trick not working is this problem with gpu or motherboard??
hello d. have a nice day. i have tgx 1080 ti . when i power it with 6+8pin it's blow fire and may be . mosfect die, 7403 FA7E 16. is there any solution ?
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, 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
I have well had the same issue with one dead regulator and blown fuses, i replaced them and there was no more short but the gpu still wont give me a video signal and the gpu and the regulators dont seem like they are heating up at all. i am new to fixing gpus and id like to ask if you might know where the problem could be or what else i should check
Heed help, Xfx rx 580, no boot, has 3 beeps 1 long 2 short, resistance ok 0.6 omh gpu 22omh memory, when used with 2nd card shows error 43 and recognized as rx 590, its dual bios, gpu starts getting hot, with these days prices i need it to work, anyone knows software which can show specific vram chip fault?
