Nice job! It's good to see someone still troubleshoots at the board level. It makes sense to put a little time into doing so with current GPU prices the way they are.
@@TechCemetery i will try it tomorrow. It's on the zotac 1080ti. I had a short on it. Changed the MOSFET it's not shorted anymore. Card detected error 43. Gpuz not showing any information on gpu/memory but rocognized as 1080ti. You guessed maybe dead memory. So i'll check And i hope the gpu didn't suffered from this short.

Great video, the 30 series cards look a bit more complex than previous designs so great to see they're still fixable. As always your troubleshooting skills are on point. And congrats on getting the fluke, that's a very nice multimeter. You should maybe get some sharper probes for it, they help a lot when trying to measure SMD components and I've found that good quality probes also generally make a multimeter's continuity mode more responsive.
@@TechCemetery honestly I got a cheap pair on ebay for like £15 and they're still much better than the ones that came with my meter, but I'd guess the expensive ones would be even better
Tech Cemetery i saw your video in full , its a great start as a repair electronics tech/eng. Those resistor that you have replaced are not just simple resistors , perhaps you have not yet heard / seen many faults , due to your age , these resistors are fusible too , Fusible Thin Film Chip Resistors , they purpose is to protect against hazard and random spurge current on power rail that are know/use to be driving all sorts of commands voltages / currents of ic controllers , due to Miller plateau effects in semiconductors . If you study a power controller you will see how currents go in or out from rail to load and sometimes , randomly due to load high variation consumption (on/off time which is not quite 0 or 1 in absolute term ) of cc will cause those resistor fuse to blow up / burn in due to current reverse circulation to rail switching from a state to another . Its complex but learnable . Go get your master in electronics , play with these only while studying . Real money are not in repairs of consuming products . It doesn't pay the bills . Fine while you learning study etc . Good job , just remember just above broke .
Good job finding that! That was amazing. If both resistors were toast, to me that would indicate a massive overcurrent condition at some point. Maybe caused by liquid, I dunno. In any case, nothing expensive died with them.
Hi I have a gigabyte rtx 3080 oc and it doesn't give any signal I used all the normal methods from changing the cables to changing the thermal pads to washing the card with a special substance and it didn't work. I even put two cards and connect the new card to the screen with the same result The device is working and the cards are working and there is no signal Are there additional recommendations to find out which piece of the card board is damaged and responsible for the problem? Any help please? There are no repairers for this type of card in my country
Wow the pex resistance is so low on these new cards but did you check the 1.8 resistance again after the repair and see if it changed as you stated you suspected that it was a little low for what you expected but as allways you smash it at repairing gpus what is the main faults you look for when purchasing dead gpus much love man and keep em coming ❤️💯
Yep, I checked it again. It sits at 240 more or less depending on how hot/cold the GPU is. It's a weirdly low reading and yet the GPU seems to work without issue. I suppose it might actually be a perfectly normal resistance rating for this card.
3:10 on your video, this capacitor that you point out giving me a voltage reading of 11.9V instead of 3.3V as you shown us. Can you please tell me what I can do? I am a noob so I am really happy that there is someone like you who are willing to share his knowledge for the sake of others. Thanks and have a nice day.
if dell voids warranty because i changed thermal pads on my 3080, i want you to take a look at it for video purposes. I think the Dell dual fan 3080s are some of the junkiest ones out there and should be exposed haha
They can sometimes - you'll see AIBs using 0 ohm resistors where they really should have a fuse. For this card though, I don't think that's their purpose.
Just found this video trying to fix my dead 3080. @1.18 You check one of those R15 inductors to check the main power rails. I do that on mine and the inductor doesn't charge. How would I diagnose from there? Thanks for your videos!
You have wooden table where you are doing the hot air desoldering. Is that safe? Anyway, great that it got repaired. So small defect, impossible to see with naked eye, but was discovered by carefully looking if all voltages would be in spec.
If this were my card I would find a way to lower the memory temps. Like a copper mod. Something to reduce the temps at least 20 degrees or more. This card would last a long time if cooled down a bunch. Those 1ohm resistors should be changed to zero ohms but that is minor nit picking.
Is that a fuse at 3:14 with "Q" written on it? I'm surprised Gigabyte use fuses and Asus don't. Asus used to put fuses on their older cards. I had a GTX 560 Ti that lasted 10 years before the GPU chip died. BTW which of these brands would you recommend for the 3000 series (specifically 3070) Asus, Gigabyte, MSI, or Zotac?

I get that the idea is to educate on how to fix these yourself, though this unit should have been in warranty, though Gigabyte is known to be very picky for any suspected customer induced damage edit: When I made the comment, I didnt watch the video yet. I now see there is customer induced damage and modifications, so yeah, this was a good candidate for 3rd party repair.

@@TechCemetery if its not a problem for You please tell me how can I send my GPU to you or people who could know how to fix this type of issue. Glad u answered
There are a couple things I'd check. You'll want to check the first pair of capacitors for the PCIe lanes on the back of the card, if they're missing or damaged ( as in not 220nf) that can cause the card to be undetected. The BIOS is the next possibility and the resistors around it. The most likely scenario though is that you have a dead GPU like TeamTDU has mentioned.
I have a puzle for you. Card asus r7 370. Boots to windows. Have display. Now gpu-z have no information about the card. literaly all tabs are blank. Windows have no idea were the display is coming from.(in device manager) ATI cant detect card so no drivers. HWinfo does detect gpu and its showing 150 h on gpu and similar on memory. I have replaced bios chip and flashed new bios. is gpu chip gone? good videos. keep it up.
I'm inclined to think the BIOS first. Many of the values in GPU-Z have to be read directly from the BIOS including BIOS version. I'm not suggesting a software flash would be enough, it's possible the chip resistors around it are at fault. I've never personally seen this problem so my guess is pure conjecture.
I have a TI version of this card with similar simptoms, however mine does have 5v on both ends of those 0ohm resistors, but does not have vref or refin voltage. The 35ohm resistor you had suspisions but turned out to be ok has 560 ohms reading on mine. Enable reads 0v, the one above enable on top side reads 5v in 2.4v on the other end. Any suggestion on how one might proceed in my case?
great job! Very nice video also, always nice to be able to learn something :) A GPU that boots, gives BIOS screen, able to install windows, but screens turns black as soon as Nvidia drivers are installed, is 99% dead GPU chip ? Have an old 1060 3GB doing it, all power rails up and running. Keep up the good work!
I usually assume it's the GPU if those are your symptons. I have a 1080 Ti in my possession that does that, it has a very low resistance on 1.8V (462 Ohms where we expect to see 850). Sometimes the memory can be at fault, or the capacitors behind the memory chips if any of them are missing, but like you mentioned, the most common culprit is the GPU itself.
yor videos are awesome, in my country is very hard to get a 3080, I mostrly work with AMD and I have learn a lot from your content, yesterday a client gave me a GTX3080 HP OEM its the first time I get my hands on one of these, is beautiful! the thing is tha all the power lines are present, but there's no video and no hardware present, do you have any sugestion?
Buenas, tengo una zotac rtx 3080 tiene todos los voltajes pero luego de unos segundos caen los voltajes de vcore y vram si mal no recuerdo y no da video, no postea bios siquiera, sugerencia?
I have 1,1V on resistor of VRAM. What could possibly be the other thing to check out? Till that moment everything else was the same as on your video, can you please help? I have the same card and the same problem
Hi! I have an 3090 fe , my problem with this one is is getting power, starts and stop with pc but is not detected in windows…. I have 2 on the same pc one is show up and one not, i try to switch cables but same problem…… any ideea?
I’m trying to fix my card following your video. My 3v is reading 12v assuming I checked the right component I checked the big brown one in front of the black one at the 3:15 minute mark. I’m also not getting a 1.8v on either side of the inductor. I’m not getting nothing on the vrm chokes, pex rail and memory.
Nice one, all of that troubleshooting madness turns out to be dead 0 ohm resistor. Also nice brand new multimeter there, ofc with more accurate reading. Actually i have a lot of question whether it's worth or not buying dead GPU with burned capacitor near gpu vrm until it scraped the protective pcb layer. The another card is dead GPU vrm but this one kinda afraid me because of your last AMD card vrm repair. Oh also thanks for your videos i managed to repair RX 560 few days ago and i can finally retire my old AMD R9 card.
I avoid cards with burn damage and shorted PCB layers, I'm not very good at digging out a PCB short and there's also the fact that it has far less value even if it restored to working condition. As for the card with a dead GPU VRM, I avoid them if I can - unless it has a fuse. And nice to hear about the RX 560, is this the same card you asked me about a month ago?.
@@TechCemetery ok then looks like I'm gonna wait until i found another dead card. About the card, the old one was XFX RX 550 which i decided to give up and use it as spare parts. The new one is Powercolor RX 560.
Yeah, but losing $7 isn't so much compared with this 560. The performance a little bit worse than my R9 but at least it's far more power efficient which is what i want
I am getting 93 k Ohm on the 1.8 V test point on the front of the card and 12 V on the capacitor on the back that you tested for 3.3V. The GPU itself is not getting hot either. I have the 1.8 V but am missing GPU VRM as well as the next 2 points you tested, the memory and did you say pex? Any tips? EDIT: I found a boardview for the card and the capacitor that you are showing for 3.3V is labeled as 12V. Were you maybe testing somewhere else?
I have a Gigabyte Gaming OC RTX 3080 12gb, I've had it for 2 days. The first day I had it, it ran perfectly fine. I even ran TimeSpy a couple times. The next day I wake up and my brand new PC has no video output. I could NOT get an output. I ended up having to hold the power down to shut it off (a cardinal sin). I finally got in bios with HDMI on motherboard (And THIS is why I would NEVER buy an F variant cpu) and my GPU was not being recognized. It was as if it wasn't even in there! I took it out and checked it out, made sure none of the power pins pushed in, reseated it, and it has been working fine every since. I am worried though! Why would it do that?
Sounds like the card wasn't seated right from the beginning, and or the card is sagging in the slot. Next time do this, loosen the mounting screws on the motherboard, insert the card in the pcie slot, then tighten the motherboard screws back up. Sometimes, cards won't align up right in the slot if the motherboard is shifted too much to one side. Tightening the screws up after the card is inserted, allows for better slot to card alignment. You should also consider using something to prop up the back of the card, as heavy cards sagging will also cause this issue.
Hello i see Your video..i have same problem on my 3080 gaming oc..i try to change resistor? I try with multimeter and the resistor 0 is not short..in case i can send you card for repair?
Well my 1070 died and i finally found the issue, dead capacitor if i short the connectors it turns on, obviously just checked if it turns in not going to use it like it is My issue now is trying to find somewhere i can buy minimum 4x 270uf 16v SMD capacitors under £10 everywhere I’ve find is at least £17 and its annoying me... Can i just use 330uf instead or will something bad happen?
Hello I have a 980 ti asus strix that does not give video, they turn on the fans very fast. This happened after a power failure in the wall socket. There are 2 SMD capacitors that do not ring with the multimeter to ground, they are top left by the vram driver. If I connect by PCI it turns on the fans, the same with the source. The GPU gets hot to the touch if I pull out the heatsink. What opinion can you give me if you can?
I have this same exact card, swapped out the thermal pads because the one was melting away and my memory was throttling at 110c. Booted right up and temps immediately dropped, highest it hit was 80 or so. Minutes later the screen started flickering and went black, now it wont boot with the vga light on. Any recommendations of where I should look for shorts or bad resistors? This video gave me some great insight, thank you so much!
@@Friend_of_the_One-Eyed_Ladies Thanks, I didn't actually know they were a thing. I'll try to remember that the next time I come across a dead 0 ohm resistor.
I am on my 3rd Gigabyte RTX 3080 in two months and one rog strix RTX 3080. All problems. All retuned. I am now waiting on a evga. Until the evga arrives, my current issue is I cant get the card past 50% utilization during gameplay. There is nothing else to update. Nothing else to install, reinstall. I've ran ddu. I've reinstalled windows, the bios has been updated on the mobo. Etc. I have a 3070, that has zero troubles. Runs top. But my 3080's have so many problems. I even got a new pc after the second 3080. Still doesn't work.. That's 4 failed rtx 3080 in row? How is this possible? Current build is a RTX3080, X570 TUF PLUS, Ryzen 7 5800x, 32gb ram Gskill 3200mhz. Corsair liquor cooled, corsair 850w gold psu. My other build is the same except a 3070 & 16gb ram. My 3070 games WAY better and mines more stable than my 3080. 3080 will lhr lock regardless the settings. Which is also frustrating and I wasn't able to game until I started locking the volts on the 3080. But now I can't get past 30-50% utilization on the gpu. Meanwhile the cpu is running 40-60% utilization. I don't get it.
Hello, very good, your channel, I wanted to know if the rtx 3090 gigabyte, if it has a fuse, connect riser mining and you can see that it made a short, and the mother does not recognize it, when I connect it to the source it turns on the fan but it does not give me an image , as if it would not be connected to the pci port
I got an issue with 3080fe Took it from Nvidia and instal to the pc The pc doesn't recognised the card. I did a windows recovery and only after that it start work.
Please someone help! My Rx sapphire 580 8GB does not work the fans don’t spin i get no display but the leds on the gpu work and the gpu is not detected in windows and also not in my bios any help would be insanely appreciated!
On 1.8v rail is low resistance as you measured - 241ohm. Is this resistance stay after you repaired card or its changed ? I'm asking because of measuring this new cards profile.
@@Mahdi-bb6dj hello, i hope what i say may be useful, and if you already know this, i do not mean to patronise: to find dead component, try 'voltage injection'. as u inject voltage and increase current limit each time, use rubbing alcohol or freeze spray to see which part warms up, that would indicated which part is dead.
Nice video!! I just repair a 390x with non power. But now i have another problem the card its give me a black screen after a while of playing. Any idea what can it be? Thanks
Cards that black screen under load usually have a bad GPU. If you have an oscilloscope, you'll want to check the waveform of the GPU VRM phases. Because of how old the 390x is, the first thing I would do (after checking the VRMs) is to try a reflow.
@@TechCemetery thanks for responding me. I don’t have a bga rework station. I have air gun quick 861, can you tell what temperature/air I need to use , to not kill the gpu? (Sorry about my English,iam from Italy) Thanks
I've never reflowed a GPU with a hot air station sorry, I wouldn't know what temperature to set it at. The solder balls under the GPU should melt at around 218*C ish. Be careful.

@@TechCemetery oke.i'll try it. Thank you
I have a puzle for you. Card asus r7 370. Boots to windows. Have display. Now gpu-z have no information about the card. literaly all tabs are blank. Windows have no idea were the display is coming from.(in device manager) ATI cant detect card so no drivers. HWinfo does detect gpu and its showing 150 h on gpu and similar on memory. I have replaced bios chip and flashed new bios.
is gpu chip gone?
good videos. keep it up.
I'm inclined to think the BIOS first. Many of the values in GPU-Z have to be read directly from the BIOS including BIOS version. I'm not suggesting a software flash would be enough, it's possible the chip resistors around it are at fault. I've never personally seen this problem so my guess is pure conjecture.
Thx. I will investigate.
I have a feeling gpu chip might also failing.... Learning more every day.
It's good time to be a live.
Nice, thank you 👍🏻
Nice job- enjoy that fluke. Great meters
Have you had any 3080s with an issue of no display output yet the gpu functions as an alternative gpu fine. Drivers install with no issues.
Sir if the 1.8v not present possible the gpu chip is dead?
I have a TI version of this card with similar simptoms, however mine does have 5v on both ends of those 0ohm resistors, but does not have vref or refin voltage. The 35ohm resistor you had suspisions but turned out to be ok has 560 ohms reading on mine. Enable reads 0v, the one above enable on top side reads 5v in 2.4v on the other end. Any suggestion on how one might proceed in my case?
great job! Very nice video also, always nice to be able to learn something :) A GPU that boots, gives BIOS screen, able to install windows, but screens turns black as soon as Nvidia drivers are installed, is 99% dead GPU chip ? Have an old 1060 3GB doing it, all power rails up and running. Keep up the good work!
I usually assume it's the GPU if those are your symptons. I have a 1080 Ti in my possession that does that, it has a very low resistance on 1.8V (462 Ohms where we expect to see 850). Sometimes the memory can be at fault, or the capacitors behind the memory chips if any of them are missing, but like you mentioned, the most common culprit is the GPU itself.
yor videos are awesome, in my country is very hard to get a 3080, I mostrly work with AMD and I have learn a lot from your content, yesterday a client gave me a GTX3080 HP OEM its the first time I get my hands on one of these, is beautiful! the thing is tha all the power lines are present, but there's no video and no hardware present, do you have any sugestion?
Check for any damaged components connected to PCIe pin A11, and the PCIe capacitors on the back.
I RMA'd my card as it continously crashed within 1-2h to blackscreen and reboot(not a temp issue). But what is that issue?
Buenas, tengo una zotac rtx 3080 tiene todos los voltajes pero luego de unos segundos caen los voltajes de vcore y vram si mal no recuerdo y no da video, no postea bios siquiera, sugerencia?
I have 1,1V on resistor of VRAM. What could possibly be the other thing to check out? Till that moment everything else was the same as on your video, can you please help? I have the same card and the same problem
Hi! I have an 3090 fe , my problem with this one is is getting power, starts and stop with pc but is not detected in windows…. I have 2 on the same pc one is show up and one not, i try to switch cables but same problem…… any ideea?
I’m trying to fix my card following your video. My 3v is reading 12v assuming I checked the right component I checked the big brown one in front of the black one at the 3:15 minute mark. I’m also not getting a 1.8v on either side of the inductor. I’m not getting nothing on the vrm chokes, pex rail and memory.
The resistance on my 5v is 236.4 ohms 1.8 is 320 ohms pex is 4.4 ohms memory is 35.8 ohms
Amazing!
Nice one, all of that troubleshooting madness turns out to be dead 0 ohm resistor. Also nice brand new multimeter there, ofc with more accurate reading.
Actually i have a lot of question whether it's worth or not buying dead GPU with burned capacitor near gpu vrm until it scraped the protective pcb layer. The another card is dead GPU vrm but this one kinda afraid me because of your last AMD card vrm repair.
Oh also thanks for your videos i managed to repair RX 560 few days ago and i can finally retire my old AMD R9 card.
I avoid cards with burn damage and shorted PCB layers, I'm not very good at digging out a PCB short and there's also the fact that it has far less value even if it restored to working condition. As for the card with a dead GPU VRM, I avoid them if I can - unless it has a fuse. And nice to hear about the RX 560, is this the same card you asked me about a month ago?.
@@TechCemetery ok then looks like I'm gonna wait until i found another dead card. About the card, the old one was XFX RX 550 which i decided to give up and use it as spare parts. The new one is Powercolor RX 560.
Ahh, shame about the RX 550. At least you now have a replacement for the R9.
Yeah, but losing $7 isn't so much compared with this 560. The performance a little bit worse than my R9 but at least it's far more power efficient which is what i want
Oh btw another question, can i use fan with 3 pin connector on gpu with 4 pin header?
At the inductor I'm getting 0 to 0.3v at 3.24 in the video. Any ideas on where to go from there? Any help appreciated.
I am getting 93 k Ohm on the 1.8 V test point on the front of the card and 12 V on the capacitor on the back that you tested for 3.3V. The GPU itself is not getting hot either. I have the 1.8 V but am missing GPU VRM as well as the next 2 points you tested, the memory and did you say pex? Any tips?
EDIT: I found a boardview for the card and the capacitor that you are showing for 3.3V is labeled as 12V. Were you maybe testing somewhere else?
What settings do I need to use on a much less fancy multimeter?
I have a Gigabyte Gaming OC RTX 3080 12gb, I've had it for 2 days. The first day I had it, it ran perfectly fine. I even ran TimeSpy a couple times. The next day I wake up and my brand new PC has no video output. I could NOT get an output. I ended up having to hold the power down to shut it off (a cardinal sin). I finally got in bios with HDMI on motherboard (And THIS is why I would NEVER buy an F variant cpu) and my GPU was not being recognized. It was as if it wasn't even in there! I took it out and checked it out, made sure none of the power pins pushed in, reseated it, and it has been working fine every since. I am worried though! Why would it do that?
Sounds like the card wasn't seated right from the beginning, and or the card is sagging in the slot. Next time do this, loosen the mounting screws on the motherboard, insert the card in the pcie slot, then tighten the motherboard screws back up. Sometimes, cards won't align up right in the slot if the motherboard is shifted too much to one side. Tightening the screws up after the card is inserted, allows for better slot to card alignment. You should also consider using something to prop up the back of the card, as heavy cards sagging will also cause this issue.
If the pin 1 and the other one dosent peep or giving 0 what should i test ?
Hello i see Your video..i have same problem on my 3080 gaming oc..i try to change resistor? I try with multimeter and the resistor 0 is not short..in case i can send you card for repair?
Well my 1070 died and i finally found the issue, dead capacitor if i short the connectors it turns on, obviously just checked if it turns in not going to use it like it is
My issue now is trying to find somewhere i can buy minimum 4x 270uf 16v SMD capacitors under £10 everywhere I’ve find is at least £17 and its annoying me...
Can i just use 330uf instead or will something bad happen?
i have a gtx 1070 8gb fans are running but i dont know how to check it if its dead ir not
Hello I have a 980 ti asus strix that does not give video, they turn on the fans very fast.
This happened after a power failure in the wall socket.
There are 2 SMD capacitors that do not ring with the multimeter to ground, they are top left by the vram driver.
If I connect by PCI it turns on the fans, the same with the source.
The GPU gets hot to the touch if I pull out the heatsink.
What opinion can you give me if you can?
I have this same exact card, swapped out the thermal pads because the one was melting away and my memory was throttling at 110c. Booted right up and temps immediately dropped, highest it hit was 80 or so. Minutes later the screen started flickering and went black, now it wont boot with the vga light on. Any recommendations of where I should look for shorts or bad resistors? This video gave me some great insight, thank you so much!
I replied to your email,
Is the card detected in device manager when used as a secondary GPU?.
@@TechCemetery Yes it is
Amazing, but, for a layman, can you explain the difference between zero ohm resistor and a bridging wire? I literally do not know and am very curious
A zero ohm resistor is basically is a wire.
There are also 0 ohm resistors that are fusible. Given the fact that both of these were fried, I'm guessing these ones were fusible ones.
@@Friend_of_the_One-Eyed_Ladies Thanks, I didn't actually know they were a thing. I'll try to remember that the next time I come across a dead 0 ohm resistor.
I am on my 3rd Gigabyte RTX 3080 in two months and one rog strix RTX 3080. All problems. All retuned. I am now waiting on a evga. Until the evga arrives, my current issue is I cant get the card past 50% utilization during gameplay.
There is nothing else to update. Nothing else to install, reinstall. I've ran ddu. I've reinstalled windows, the bios has been updated on the mobo. Etc.
I have a 3070, that has zero troubles. Runs top. But my 3080's have so many problems. I even got a new pc after the second 3080. Still doesn't work.. That's 4 failed rtx 3080 in row? How is this possible?
Current build is a RTX3080, X570 TUF PLUS, Ryzen 7 5800x, 32gb ram Gskill 3200mhz. Corsair liquor cooled, corsair 850w gold psu.
My other build is the same except a 3070 & 16gb ram. My 3070 games WAY better and mines more stable than my 3080.
3080 will lhr lock regardless the settings. Which is also frustrating and I wasn't able to game until I started locking the volts on the 3080. But now I can't get past 30-50% utilization on the gpu. Meanwhile the cpu is running 40-60% utilization. I don't get it.
cool videos!
Hi, Please answer me. Which chip controls fans?
Hello, very good, your channel, I wanted to know if the rtx 3090 gigabyte, if it has a fuse, connect riser mining and you can see that it made a short, and the mother does not recognize it, when I connect it to the source it turns on the fan but it does not give me an image , as if it would not be connected to the pci port
Same hapened to my rtx 3080 do you know if rtx 3080 has a fuse ?
i think i want to get into gpu repair. where should i start looking?
I got an issue with 3080fe
Took it from Nvidia and instal to the pc
The pc doesn't recognised the card. I did a windows recovery and only after that it start work.
Please someone help! My Rx sapphire 580 8GB does not work the fans don’t spin i get no display but the leds on the gpu work and the gpu is not detected in windows and also not in my bios any help would be insanely appreciated!
Hello, can you help me please where can I buy memory modules for my board rtx 3080 msi gamin x trio?
Hey. Where do you get schematics?
cool stuff. :-)
I’m just curious as of how much this usually costs if I fry my gpu or if something like the resistors just in case I mess up lol
On 1.8v rail is low resistance as you measured - 241ohm. Is this resistance stay after you repaired card or its changed ? I'm asking because of measuring this new cards profile.
It's still the same, I checked it again after testing.
@@TechCemetery thanks man !
Hi, my pcie 3.3V pin is shorted, i have a 1080 ti and its not detected. What should i do?
I asked because you always check if its shorted.
Find the shorted component and remove it, sorry there's no advice I can give you beyond that.
@@TechCemetery I would try but i dont know how to find the component. Thank you for answering
@@Mahdi-bb6dj hello, i hope what i say may be useful, and if you already know this, i do not mean to patronise:
to find dead component, try 'voltage injection'. as u inject voltage and increase current limit each time, use rubbing alcohol or freeze spray to see which part warms up, that would indicated which part is dead.
Nice video!!
I just repair a 390x with non power.
But now i have another problem the card its give me a black screen after a while of playing. Any idea what can it be? Thanks
Cards that black screen under load usually have a bad GPU. If you have an oscilloscope, you'll want to check the waveform of the GPU VRM phases. Because of how old the 390x is, the first thing I would do (after checking the VRMs) is to try a reflow.
@@TechCemetery thanks for responding me.
I don’t have a bga rework station.
I have air gun quick 861, can you tell what temperature/air I need to use , to not kill the gpu? (Sorry about my English,iam from Italy)
Thanks
I've never reflowed a GPU with a hot air station sorry, I wouldn't know what temperature to set it at. The solder balls under the GPU should melt at around 218*C ish. Be careful.
@@TechCemetery thanks.
