Old repair technician chiming in, he said "make sure no one else have attempted to repair it". Those words right there - spot on! The worst repair cases I ever had is from incompetent repair attempts and you will NOT believe the stuff I've seen. I've seen attempts where people have literally FORCED their soldering iron right through a 7 layer PCB board (that's unrepairable right there) and the unit is destroyed forever. It almost always pays to purchase units that no one has attempted to repair before, but sadly - so many dishonest people just sell their failed repair attempts.
you got a website to send in gpu's? i have someone who needs help swapping vram from one "DEAD 1080ti" to another 1080ti that is dead but that one only has vram issues the other 1080ti has a hole blown in the pcb about 4 layers down making it parts
That's just fucking abuse at that point
Pro vintage audio tech here. You are absolutely correct. I hate working on something after someone else has tried to fix it. The only thing worse is an intermittent.
that's always my worst fear and I will say I never soldered electronics so I usually get a friend to do it who has I realy need to teach my self so I don't have to pay someone else to do a 30 second job
someone put in all the screws on the magnet in an iPhone 6 I took apart for a broken screen, guess that was their little screw storage
The fact that a broken rx 580 in these days is more expensive than the one i bought used 3 years ago is nuts
I bought a used vega 64 two years ago to replace a no-longer-compatible 980 for my hackintosh and sold it for twice what I paid a year after that when I managed to buy a 3080 for a new build.
I was thinking the same. It's insane.
GTX 970 cards go for $150 used, not $300. $300 buys you a used GTX 1080

"It's working but we've got no idea what we did..."
Years ago, AT&T had an official resolution code for their techs, when we'd call in a line problem that just started working while they were troubleshooting: FWT = Foxtrot Whiskey Tango = Fixed While Testing :D
I have a done this to a few computers. While testing to see what's wrong I accidently fix it, then have to go back and figure out what I did to fix it. The silliest is when you unplug and plug something back in and it magically works again. I have done it with routers, ethernet ports, internal laptop monitors, RAM, graphics cards, TV's, once a car.
@@rrteppo I don't think that's silly at all - Remember that unplugging and plugging it back in loads every setting back to it's starting point. There are SO MANY ways that bits and stuff can be flipped unintentionally which stops the system from working.
@@rrteppo explain the car
Dirty contacts on the car battery? Removing and replacing them is usually enough to clean them.
@@embersaffron5522 Computer chips have been common in cars for like 30 years. Aside from that, plenty of engine parts could be "fixed" after a restart because they pressurise and seal better. Especially if the engine has had a chance to cool.
$400 for a damaged 1080ti is WILD 😅 I know the videos 8 months old but sheesh
Yeah man, looming online now used 1080s run like $300

@@Kyomara1337 Thanks for the heads up! I actually checked that and you are completely correct. 👌 Thats super handy

like, wtf
@@desaturatedair in what dream world are you living where a 6650 xt has way more performance than a 1080 ti?

"I just bought 7 dead gpus for _only_ $1700"
Sir you and i are still on very different playing fields
I was gonna say, imagine paying $400 for a GPU that the seller says isn't working. Actually imagine selling a GPU that you think is broken and expecting $400.
The GPU marked is totally fucked, even dead GPUs are selling for a premium
@@aefilmsweddings yeah I noticed that, dude got scammed hard.
@@aefilmsweddings Well clearly someone got 400 for the totally dead one lol
Lol, they're basically selling for the same amount or more that they'd be worth new in a reasonable market.
I like how Linus warned nearly every intel tech upgrade recipient that their PSU was a little underspecced, yet origin here is casually throwing in 850W for a 3080Ti and 12900K
A true sleeper build 😪
Faxx
But I guess it ain't toooooo dangerous.
Hard to imagine they couldn't manage a better one with that kind of budget
Replaced 95% of my current build recently including psu and only spent $740 and it's a 1300watt
850w is enough for that spec of a build. its on the low side but in no way is it dangerous/sketchy.
And they had problems too
What’s funny about the sticker thing is they did a whole video about how to take those kind of stickers off and put them back on without the manufacturers being able to notice and deny a warranty
In the US they cannot deny a warranty based off a voided warranty sticker funny enough, not sure if that applies in any other countries
About the oven trick: It's definitely worth a try. I've had 2x 780 ti for years where one of them stopped working, I fixed it with the oven method which made it last 3 months, fixed again and it worked 2 months more then it wouldnt work again. My second card stopped working later and after I ran it in the oven it has been working for 8 months right now, hope it will last more :)
Is your card still running?
-if so, you better go catch it-
I worked at a computer repair store for awhile, and it seems that the "dead" electronics people brought in were almost always split into two categories: Not really dead and power-cycling brought it back, and so dead that we didn't have the time, budget, or equipment to fix it. I didn't really get any satisfaction out of either category.
"we didn't have the time, budget, or equipment to fix it.", what kind of "computer repair" store were you then? Geeksquad? lmfao.
Wow then you worked in a teribble store
@@evolicious There's two approaches to making money fixing dead electronics... either you charge a flat rate or you charge per hour... either way you gotta get shit done fast. If you take too long attempting to fix stuff, the company loses money. Fixing something like a dead GPU could take a day or more and no customer would pay that bill.
@Will actually KR4FT had it right. We charged both fixed and hourly rates depending on the job. The issue is that most customers didn't feel like paying $200 for parts and materials to fix a bad memory controller on a 6 year old laptop that sold for $700 new when they could buy a comparable new laptop for $300. I live and worked in Sweden, so taxes make any service like computer repair expensive while buying new stuff is only slightly more expensive. Of course, if it was a new and expensive electronic, we were certified to make quotes for people's insurance companies. The insurance companies write off electronics 7 out of 10 times. We didn't get to genuinely fix things often.
@@evolicious You pay technicians around $20 per hour, sometimes it takes hours to fix a GPU, and the advanced repair stuff costs stupidly much (that microscope linus has is already few grand). Still don't see a flaw in your logic lmfao?
Would love to see more "Can We Fix...?"-type videos. With component prices all over the map, logistics shutting down every other month, and other... uh... geopolitical issues, this could really save someone's bacon. Odds aren't great -- it is eBay, and the parts are explicitly listed as broken. Still, you'll miss 100% of the shots you don't take. Also, even a bad board might be worth something to the would-be repairer, for practicing more advanced soldering techniques (like hot air reflow). It's not like you'll break it _more,_ right? 👍️
TronicsFix is the channel for you! :)
There's a dude called Bob who has a "Can we fix it" show, might be up your alley if you enjoyed this
@@kalimaa999 Must be a some kind of Builder ?
"It's not like you'll break it more" ah, stranger on the internet, you give me way too much credit. =P

That was just a "Clean it and see if it works" vid
My job involves testing very sensitive electronics. When using a DMM in auto-range mode (for resistance or continuity mode), the DMM can actually put out quite a lot of voltage that can easily damage parts not rated for that voltage. When the DMM is set to a low resistance range, the output voltage could be sometimes as high as 9V. With modern chips using core voltages as low as 1.2V, 9V is way too high and can easily kill the chip. When the DMM is set to a high resistance range, the voltage will be much lower and will be at a safer level. When set to auto-range, which is the default setting, you really don't know what you'll be getting as the output voltage. If you don't know how much open circuit voltage your DMM has and you need to check for a short, it's recommended to set the DMM to the highest resistance range and use resistance mode. When in a high resistance range (like 1M or 3M), a short will read 0 and a non-short will read at the low end of that range like 1M. The beeping continuity mode on a DMM will likely put out max voltage so its not recommended to use.
On many DMMs, the diode mode and beeping continuity mode are the same so only use it if you are checking for whether a diode is in series has the right voltage drop or if you are checking continuity on some passive wire.
One thing you can do is check the open circuit voltage of your DMM to see if it's safe enough for general use without having to set the range first. We use really old Fluke 77 DMMs because they haven't low voltage.
I'm no expert in electronics but I always liked it, I repaired a couple of things and always asked myself that, when using continuity you are putting voltage in the components... if things are delicate or too sensitive you could damage them 🤔
How do you check the open circuit voltage?
@@j.yossarian6852 use a second DMM to measure voltage between the positive and negative probes while in continuity mode and in the various resistance ranges and for autorange as well.
The DMM acts as a constant current source (typically around 1 mA) in resistance and continuity/diode modes. If you are measuring something low resistance then the voltage across your test points will be of proportionally low value, as V = IR. E.g. if your CPU resistance is 1 ohm then the voltage across it will only be 1 mV.
If you don't have a load connected and try to use a second multimeter to measure the voltage across the probes of your DMM, then you effectively have an infinite resistance that your DMM is trying to drive at 1 mA. However, your DMM is only powered by a 9V battery, so that is the maximum it is able to supply. This reading is thus irrelevant. What you should be doing is setting your second multimeter to current mode, and you will see how much power (as a fixed current) your DMM is really outputting.
@@rodrigoacosta9708 this isn't about you rodrigo, why do you have to make everything about yourself?

RE: Jono's issue.
Had the same problem with a monitor falling off. Replacing the HDMI cables addressed it.
Was going to say, it sounded to me like a cable problem.
He should bring in the cable to get it tested on site!
Having an AC cable intersecting or near the HDMI can also cause problems.
I had the same problem with a displayport, I changed the cable and it fixed it
I currently have this issue myself and can't pinpoint it.
Sent my Strix 2070S in for repair after it's been doing this intermittently and it really pissed me off playing Elden Ring. The tech found no issues and I got it back yesterday feeling a bit mad.
I bought new DP and HDMI cables, ones that passed the Cable tester video LTT did. They didn't fix it.
I have a 750w Corsair PSU and thought maybe it wasn't enough? But I put a 1660Ti in and it had the same issues.
I have a lot of plugs in my power bar so I split them between two bars, I'm currently testing this to see if this is the issue, just one power bar can't hold all of my devices at once.
Anyone else have any ideas?
Love this calm competent approach. Doing some "can we fix" themed episodes would be great. Aware hardware gets harder and harder to fix but what is worth giving a go instead of default to throw out out and replace.
I'd recommend watching NorthridgeFix, TronicsFix or one of the other for-profit repair shop channels if you want that kind of content, the LTT team don't have the same level of tools/spares/expertise as a dedicated repair shop.
Competence does not mean a thing.
He has no clue how to fix a video card.
@@cheeseburgerbeefcake I'd recommend not. Northridge fix is good to do 5 minute repairs. Video cards usually take an hour at least even if repair is small. Most of the time you spend hours.
@@tonycstech Why do you say that? Who does on CZcams? Would like to learn just out of sheer curiosity of learning how these things die(it's not worth my limited free time to spend repairing these cards).
@@cheeseburgerbeefcake that's kinda why I prefer watching here. I'm not a pro, neither are these guys. I feel like I could actually do it if they can.
2:20 it looks like it's problem might be that it punched him in the face tbh...
One reason that taking it apart and reassembling fixes stuff is that oxidation on connectors is scraped off when you unplug and plug again. For extra cleaning, remove and insert several times. You can also use a pencil eraser on edge connector fingers to remove oxidation.
PSA : When trying to find shorts on either Vcore or Vmem, never ever use continuity tests ! You'll get beeps even on a 100% working card because the loads are so small (a couple ohms maximum).
You should use normal resistance measurement and make sure that you get a "true" ~0 ohm reading
This is true because there are 0ohm resistors xD
I recommend using Ohms law.
to read truly low values the best is a 4 wire meter, also there the option of just using a external power supply and applying Ohms law again.
Diode test is the fastest way to find shorts.
Actually differentially pumped thermocouples are the way to go
Even when the card is off? I've never encountered a device that had transistors that have a closed circuit from V+ to gnd when the device is unpowered
2:38 The hardest failure to diagnose is 'intermittent' failure! If you fail to pinpoint the problem and decide to 'look around' and test components, you may end up bricking the whole thing. Most intermittent failures are faulty boards: cracked or semi fried... I always avoid touching those
The only thing worse than an intermittent repair is an intermittent intermittent repair. Quote from President of Lear Jet.
Not really Intermittent failure, just Cascading failure. That's when you replace something that is shorted and failing to check another that is also shorted and just powering the whole thing up causing other parts and *adding more shorted ICs . Just pray those ICs and MOSFETs could hold more than the voltage that was incorrectly injected into the board. What a mess
More of these videos please! They are incredibly entertaining while still being educational:)
I agree! This was super interesting!
This is one of the cooler episodes from this channel. Would seriously love to see some more of these.
It’s still mind-boggling to me what has happened to the GPU market. Their broken RX580 cost them $150, meanwhile I spent $120 for my (perfectly fine) one a couple years ago
I bought a new one in 2019 for 150$, sheesh
Yeah same and I got a couple of free games to boot
I sold my old rx580 4gb for $285 a few months ago, it's awful lol
I bought used GTX 1080Ti for $300 just before the prices went to the moon.
I know, I bought my 970 years back for $50 LESS than I sold it for last summer. Then again the 3080 I replaced it with has already paid for itself...
There's too many shady sellers that KNOW something is beyond repair but sell it for a ridiculous price hoping some person will want to take the gamble. Even for parts, these cards don't come anywhere CLOSE to what they ask for, it's ridiculous. Not to mention so many broken items have already had work done ruining them beyond repair.
bingo exactly what I was going to say
Yes. The nubs shouldnt be so cheap.
This was really interesting. I wonder how far you can go tho, I mean that card with the melted IC on it looked like it was screwed for sure but it would be interesting to see just how much you can salvage if you really go all in for it
Turn off the Multimeter when putting it away after measuring. Not only will it preserve the battery but you won't use it in the wrong mode by accident (and possibly damage it)!
No xD
7:34 you gotta be careful of this... don't clean a card right away. Take note of all the spots with corrosion and look at them in depth before cleaning. they can be a good hint as to where the issue may be.
can we briefly talk about how crazy expensive these broken cards are?
it should not be more than 10% of the new card price
With this video out, they're about to get more expensive yet.
@@SianaGearz GPUs are crazy expensive for some time now, but the discount is way to low for something that is probably trash
thank scalpers for that....they showed gpu companies what people are prepared to pay
Cards seem to be way cheap where I'm at. There's working GTX1080 for sub $300
@@alexdieringer3510 thats because they're super old and outdated
22:47 my guess would be there was a slow leak somewhere else in the water loop that dripped onto the GPU over time, probably in the CPU block
I've seen the same issues with video cards cutting out when over loading the power supply. Either the power supply itself is not strong enough for everything in the system. The other big issue is over drawing one rail. Most of the newer graphics cards need to have power supplied from two different rails/outputs from the power supply.
5:20 one thing to note is opening up netflix or any other service using HDCP will temporarly black out your screen as the protocol change, and some monitors might just have trouble with HDCP too
The weird thing: I don’t have that. My screen doesn’t even flicker and I could record Netflix with OBS
Agreed. It could also just be a crappy cable also. I see it with cable boxes and blu-ray players all the time.
i have literally never seen my screen flicker when watching any video streams and i have 4 or more streaming services depending on what 's available.
@@oldfrend I understand what you mean. "If it doesn't happen to me, it doesn't exist".
@@ohead07 I don't think a cable would cause a one time black out that could be re-created 100% of the time by a single event. This sounds more like a hardware / firmware / software issue. Maybe the drivers need updating, maybe the Monitor is too old, who knows. But if it were a cable issue, I believe that it would be noticed at other intervals as well.

Returning to this channel again. Hello. This host is super cool and entertaining to watch. Love the variety of personality on LTT.
You're awesome.
I am a total rando with zero tech background but I love fixing old broken things around the house that would just get thrown away, I enjoy doing that and after I am done I take it to the nearby shop that buys second hand stuff and sell it hella cheap and get some cash for my troubles. I find videos like this very fun to watch for the same reason. I have learnt a lot over the years watching videos and just meddling with broken stuff.
u want a gtx 770 that says its got no vram?
A short on the 12V input is actually one of the most fixable faults, most of the time a dead mosfet and a good chance the gpu itself survived.

From Analysis I logics chart: "you cannot deduct anything from a false statmement"
In the same way, you cannot expect consistent behavior from broken hardware.

@@phyro4143 I watched a lot of GPU repair from real technicians and and expecting till in the middle of the video "Where's the tools for soldering ? Are they gonna just check and see whether it's turning on or not or what?"
That fan spinning tip. On point. ❤
Never had a gpu live past 1 year the day after running furmark. RIP my 2900 xt, gtx 460, and gtx 560. Definitely spent too much time blaming it on other problems and I've only done mild overclocking.
Furmark murdered my HD7770 :(
FurMark isn't made for old cards like that my friend. For those dinosaurs you need to benchmark with 3DMark99.
I had a GTX 680 that was OC'ed and ran Fur Mark *a lot* and it's still working today on my secondary PC...
nah you def broke them in a diff way
Sure... Furmark is the culprit...
My theory for the card with the excessive water damage: The CPU in the original system was probably water cooled aswell and may have leaked onto the GPU.
But it looked like the water damage was on the side with the cooler, not the one that water would drip onto
@@Sithhy maybe it ran all the way down the card
The amount of corrosion really looks reminiscent of bleach damage (dont ask how I know)...
I was thinking same thing as I have had a few systems where they would not boot..etc and it turned out the cpu cooler leaked, dripped down the tube, landed onto the GPU cooler and then made its way to the PCIe slot, nvme slot, and even the GPU die itself while leaving leaving just about everything undisturbed. And one of these was about a single drop every 18 hrs or so unless you actually saw it dripping you wouldn't of seen it or noticed it.
@@Sithhy Yeah, so more likely a leak at one of the radiator fittings on an AIO. The card itself was an all-in-one liquid cooling solution, likely enough that's what was cooling the CPU. Given how much corrosion was on the card, it also seems like it ran for a while with a slow leak/drip on it until it died entirely.
The first GPU seem to me like a Power Supply issue, by experience having the same issue before and knowing someone who had the same issue too, both of our PSU ended up dying.
bingo 100%, that happened to me, and it was absolutely the PSU. The way it was explained to me, is that a PSU's rating goes down a tiny bit every year, so a 5 year old PSU and it wasn't cranking out the power it used to. New, higher rated PSU and zero issues.
My screen sometimes looses signal on 5m DP cable. More often with HDR or gsync turned on. Shorter cable is fine. GPU is gtx1070 on gsync compatible screen. Had no problem with old driver
@@raspberrypi4993 i had that happen with my old 400w psu which died around a month ago. now that i have an 850w psu my monitor stopped randomly disconnecting. idk if those are related by any means but yeah.
THIS. PC is all good just browsing the web, and non graphics intensive work. Monitor would just turn black after a few hours of playing, and still have game sounds. I ended up checking bios just to see if I messed up anything, and noticed that the 12 volt rail was reporting 11.4 volts! Replaced the PSU, and all is well. I'm pretty sure Seasonic is a reputable brand, and I just got unlucky with my unit.
I had a PSU POP on me before and it scared living shit out of me. Thankfully my mobo and components attached to it were safe.
For Jono's GPU, I've had that issue and it was just a bad HDMI cable, or one that was not rated for the bandwith. Swapping it resolved in my case for a GPU that would randomly loose sync/drop video or loose sync in an observable pattern.
You guys should get a handheld LCR meter. It will allow you to measure all the caps while in circuit.
Wow I didn’t know that spinning the fans that fast could be bad. I guess I won’t do that anymore. Thanks for the tech tip!
It is ~probably~ fine, but holding the fans is cheap and easy insurance -AC

Not to mention, fast spinning fan blades are a finger slicing hazard. It'll hurt quite a bit 😶
the thermal pads evga used for the "fix" for the FTW cards of 1070 and 1080 really seemed to leak grease stuff from the pads EVERYWHERE on the cards. I dont think something was spilled in that card. I recently replaced the thermal pads in my 1070 ftw and had the sticky stuff on it as well. It really let dust stick to it.
I was just coming to comment something similar. I recently re-thermal pasted my EVGA GTX 960 and it's never had anything spilled on it but those thermal pads they use have some crazy fluid that seeps out of them over time.
I have the exact same EVGA GTX 1080 and can confirm it's from the thermal pads, not from spilling.
1060 zotac mini had a similar issue
Wanted to say that too. Buddy graciously gave me his EVGA Gtx 1070 SC and when I changed the thermal paste, I recalled the gpu being coated in an oily substance. Same with backplate and mid frame. Thermal pads were some greasy bois
I had the same card and did the step up/swap to the FTW2 - I did do the thermal pad fix first

@@tyr3759 you seem sad
@@namebrandketchup2048 Sure, how about you? Been out of the bottle lately?
I’ve done the oven GPU fix on a number of occasions, especially on 2010 IMac and I can vouch it works. I don’t think it reflows this old. Are your correct on that one. But but it does definitely affect the soldier in someway. It’s the only possible thing they can be. I know dry shoulder joints or something people talk about so possibly something to do with that
A card that suddenly starts working just from taking it apart and cleaning it likely had a bit of metal dust or filings or corrosion sucked into it that shorted something, dust or other crud causing a support IC to overheat, or the thermal paste was so bad that the GPU die overheated nearly instantly and go into self-protection shutdown to avoid melting.
Cards with shorted power rails are usually quite easy to fix; scrub the card down to knock lose any corrosion or conductive dust that could be shorting it, and replace a blown MOSFET.
Or it's a small crack in a multilayer board, and reassembly stressed it in a different way so it makes connection. Or a loose via. Or cold solder you didn't find yet. Sometimes thermal cycling can help find these problems. Percussive maintenance is another sign. If you slap it and it works, it's not afraid of you it's a loose connection.
The PCI-e differential pair length matching requirement you mentioned isn't as tight as you think. For Gen3 PEX you've got a 20-80 rise/fall time margin of 19ps (i.e. on a transition the the signal must go from a 20% voltage level to 80% voltage level, or vice versa, within 19ps), which means a timing skew budget of +/-9.5ps. On FR4 dielectric that means you're looking at about a +/-1.7mm length skew budget before you go out of spec. Keep in mind, though, that "out of spec" doesn't mean "not working". If you blow that budget by an additional 50% you might still get a perfectly functional card. Bodge wires should be fine here if you're careful about length and keep it close to the surface, so it's 100% worth an attempted fix.
One thing to consider is that timing skew isn't just about length. The amount of timing skew in the transmission line is proportional to the impedance of that line, which is proportional to the distance AND the dielectric constant. When you've got an impedance-controlled PCB, the dielectric constant can be considered (unsurprisingly) a constant, which means (with careful design) the impedance of your traces, and therefore propagation delay through them, is largely just a product of length. I'm glossing over some details like fibre weave effects, copper roughness, etc., but the main thing here is that the trace is a fixed distance away from the ground plane, with a known material (the FR4 fiberglass) between the trace and the plane. Why am I bringing all of this up? Because timing skew arises from a mismatch in impedance, and impedance is affected by the dielectric constant, and the dielectric constant is affected by the trace's distance from the ground plane and the materials that are in the way.
(Side note: one thing that a lot of people get wrong here is that the distance between the two traces of a differential pair DOES NOT matter anywhere near as much as you think it might on a PCB. In a twisted wire pair the cross-coupling of the fields between two sides of a differential pair is very important, but on a PCB those two traces aren't twisted together, so the majority of the field energy is between the traces and ground plane. The two traces act much more like single-ended signals, with a small amount of cross-coupling of the fields, than proper differential signals in a twisted wire pair. The signalling also isn't truly differential in most cases with protocols like PEX, LVDS, DDR, etc. - TL;DR the lengths of the two traces must be pretty closely matched, but a consistent distance between the two traces in the differential pair is far less critical.)
When you lift a high frequency signal away from the PCB surface, through a bodge wire, you alter the impedance of that trace in a way that isn't just proportional to distance. As such the length skew isn't the only factor to consider. Lifting the trace into a bodge wire also creates an impedance _discontinuity_ (i.e. an abrupt change in impedance), which causes signal reflections that can reduce the quality of the signal and close the eye diagram. These may be small effects or large effects depending on a whole bunch of factors. It _may_ be a problem. It _may_ not be a problem. For a short distance like this, my intuition is that the discontinuity might be fine on Gen3 - if it were Gen4 PEX I'd be much more concerned.
One of the main sources of impedance mismatch will come from the repaired trace no longer being closely referenced to the underlying reference (ground) plane, since it's now a floating wire. So, if you want to get real fancy, you can scratch a bit of the soldermask off next to the locations where a bodge wire is going to/from, then solder a second piece of enamelled wire to those exposed ground points and wrap it around the bodge wire (or rather wrap them both around each other like a helix), forming a twisted wire pair where one side carries the signal and the other is referenced to ground. This ensures that the return currents for the lifted trace remain in the ground plane, that you get excellent common mode noise rejection, and that the fields stay tightly coupled rather than spreading out and causing radiated EMI problems and cross-coupling. It'll also serve to slightly curb the problems caused by the impedance discontinuity. This might not be required but it's a good option to have in the toolkit.
I know I braindumped a bunch here and it's a bit of a daunting topic, so if any of you at LTT want to chat more about this stuff you can drop me a DM on Twitter (gsuberland) or IRC (same handle, Libera network) and I'd be more than happy to talk through this stuff and clarify anything that's unclear :)
IRC still exists?? Damn, some things never change.
Would conductive paint be better than a bodge wire? That would lie on the PCB so maintain the distance to the ground plane, hopefully not changing impedance much. (how to solder the cap to it, and what the resistance of conductive paint is, I've no idea!!)
@@erichb4530 IRC is nice.
It wouldn't have fixed the card. I've seen people do 10+cm rewiring jobs from last pcie lane to first and be fine. It would have detected a lane was bad and would have used the first 8 lanes instead. Something else is wrong with this card.
obligatory "Source: Im a brain surgeon with 100 years experience"
I was given a 980 TI that seems to run on 1 x 6 pin connector, but the other one does not seem to allow it to run.
I've been trying to learn more about this stuff to trace it myself, but I do appreciate videos like this to help me learn what to look for.
I feel like sometimes the sticky shit on the pads gets all gummy and sort of runny after time. An nvme drive died on me once because the sticky foam pad that held the cover on got all gross over time and spread causing a short.
I had an old dead 770 about 5 years ago and saw the video Linus made about putting it in the oven, I figured its a card I don't care about and had nothing to lose at this point so I gave it a shot. To my complete surprise the card worked fine and still works to this day.
RandomGamingInHD and even Tech Yes City have been showing users at the (usually short term) success of such repairs, though Random has cards that sill work long after the oven fix despite it only being recommended as a temporary fix.
I heard it does something with soldering connection, repairs it with heat or something. It's a clutch move and when my GPU dies- I may try this before buying a new one lol
During Uni I had a laptop that had a removable GPU. I put it in the oven regularly as it break all the time. I have baked it at least 20 times, it came back to life every single time then I saved up for a new laptop. The bakes were more and more frequent, at the end I have baked it every week.
@@DanielBulyovcsity I can imagine someone putting their computer in an oven for their daily baking lmfao
Similar story here. Six years ago the thermal paste on my 770 got bad. Replacing it fixed the card until 2020. Then the card started artifacting and died soon after. I've been using a heat gun to reflow the solder between the prcessor and the PCB. This fixed it for six months. Then the same happened again. The next two repairs were not as successful as the card only worked for three and then one month. After that disappointment, I decided to heat up the processor way longer than recommended as I felt I had nothing to loose anymore. The card came back again and has been in use for over six months now.
My current plan is to wait for the 4070 to come out and if needed pay a scalper rather than buying of the still overpriced 30 series right now, when I might get a stronger card for the same money in october.
I'd be willing to bet the one with severe water damage was in a system that had a custom loop on the CPU and THAT leaked at some point into the GPU, killing the card. All that white crusty shit is likely the algicide/minerals in the open-loop coolant.
i hate liquid cooling
@@CaptainScorpio24 I agree. No matter how safe it supposedly is, I'll take fan failure on an air cooled setup than leakage any time of day. A failing fan is easy to notice and replace - a leak may kill the entire system or at least a GPU.
it looks like water damage, but it is not.
It's the thermal pads being shitty. I took apart my EVGA GTX 1070, never spilled anything on it, never used water cooling, and it looked exactly the same, with weird sticky watery stuff around the partly dissolved pads.
@@CaptainScorpio24 , Man, water cooling has come a LONG way in the last 20yrs. I was a hydrophobe until I put in my first Custom loop, soft line on CPU, GPU, and VRM/VSOC, so nothing fancy, but it works well, and I've had zero leaks in 3yrs now. They do require some extra maintenance, but I would say its much "safer" than it used to be when everything was essentially plumbing fixtures secured by zip ties like we had back in the early 2000s, lol. Now I can push my 1800X all the way to 4g all-core, and I didn't even have to touch the voltage (which is still stock) because the EXTRA cool power delivery seems to have smoothed out the voltage ripple to my CPU. Might be time to give H2O a chance mate. :)
@@youtubeuser5875 Probably silicone oil from the pads.
My favorite memory of a fix was when I got a rental dvd stuck in the player. Basically the door didn’t want to open when I pushed the eject button. Opened it up, didn’t unplug it, got shocked real good, and the door just glides open. Worked fine for another 8 years.
I got a free ps4, completely dead. What sat around with a mate, completely disassembled it, removed some plastic parts from the board, stuck it in the oven at max temp 250C for 30minutes. put it together again for a laugh and the bloody thing worked. still works to this day.
How is that possible

You can also try a heat gun over the disassembled board.

@@mistarbeanz 2nd this. Thank you. These are brushless motors. Won't do what was mentioned at 3:15
@@TristanVash38 why brushless won't? I thought every motor can except those that doesn't have permanent magnet
IDK about the electrical current from fans spinning causing any issues, however spinning GPU fans at speeds which far exceed their intended limit can and does often destroy them. Most of these fans are cheaply made with plastic motor casings, glued construction and often *no* bearings at all.
@@mistarbeanz I think its more of an over simplification. A fan won't make a very good generator, but it can produce current if it is forced to spin.
It has little if anything to do with the fan speed, the point is that a fan turns electrical energy into kintetic energy by using electromagnets. If you provide kinetic energy instead of electrical energy to make the fan spin, at a certain point the electromagnets will eventually produce a current.
The design of an elecrtic fan and a wind turbine share a lot of similarities. You can't use a fan to try to power your computer or anything like that, but you might be concerned about some of that current making its way in to your logic boards somehow. In practice its pretty unlikely thay the current would leave the fan controller circuits, but in some cases forcing them to spin could damage fan controllers. I am not an engineer, but I would assume that some if not most of the circuits to control and power the fans have some protection built in to stop them getting damaged, or at least naturally tolerate the low voltages that might occur from breezes.
In general with complex technologies it doesn't hurt to err the side of caution, which is why people advise you to be careful with things like grounding yourself, keeping your workspace clean and so on. It is not necessary, and in most cases you can ignore it, but it is easier to be careful and follow that advice than it is to learn exactly when those rules are actually vital and necessary, which usually gets learned the hard way by destroying equipment.
I fixed my gtx 1660 which had a failed vram chip (confirmed using MODS). I bought the gddr6 module from aliexpress, which was the only place I could find it for sale. Used hot air to remove the old one, and to solder on the new one. Card is still working great seven months later.
I never knew about not letting your fans spin with compressed air....that's the most fun part lol
"A lot of the time, just, Disassembling and reassembling stuff that's dead, is the easiest way to fix it. You won't know why you fixed it, but it just does"
I cannot POSSIBLY tell you how many times this has happened and worked for me. After cleaning, and rebooting, I just take stuff apart and put it back together, and then it magically just works. No answers, just solutions.
Also, the number of horror stories of trying to work with something someone tried to repair in the past, only to find it completely destroyed beyond repair: Insurmountable.
Thank you for this video. I absolutely loved it as a Professional Technician and Hobbyist Engineer.
"Fluff up the parts" - term I heard for that case where taking it apart and re-assembling just fixes it. :D
This works sometimes with liquid damage as well, but if you don't clean well enough it will be broken worse in a couple of weeks. Had to replace both right side charging chips on a liquid damaged macbook because the liquid cleaning only lasted a week.
Alex: Nice tip on the fans,(cleaning) however, you didn't mention that the fans bearing has a specific rating based on lubrication and surface. You can very easily take a fan beyond it's speed/heat rating with a compressor. Start it back up and your fan doesn't work, or squeaks? Probably killed a bearing.
Never thought this was a real thing, cleaned plenty of PC's no issue... Until I did it. Then did it again to be sure lol. I always stop the fans from spinning now when cleaning! Also sub tip to the above... Get/use a moisture trap when using a compressor!!
@@deathfiend666 considering all the money reported to the shop I'd be surprised if they don't have it in line
yeah from what i've heard it's usually not the fan generating current and killing the board but the fan spinning too fast and killing them bearings like you said
fan bearings are usually pretty highspeed - more than they usually run at normally.
I liked the episode, good stuff. There will be plenty of used mining GPUs on the market after the Ethereum merge I would imagine.
Just commenting on your last bit of the video (oven method). I bought a GeForce GTX 1080 Xtreme Gaming 8GB for $100 on marketplace (labeled as used- good and promised that it was working- I knew it wasn't gonna work well). Lo and behold, artifacts! My PC crashed constantly. Would restart and blue-screen on me. I cleaned it up, applied new thermal paste, new pads, and still had artifacts. I did the oven method and it worked with 0 issues. I have done this to 3 different cards and they're still gaming strong with no issues a year+ later. It may be luck, or it may be that it actually works most of the time. Idk, but so far..It's been a good cheap method to fix GPU's that have been artifacting. I've never had any issues that people bring up to debunk it or that it stops working after a short time.
Bloody hell, we live in a time when a 4GB RX 580 sold as not working can be sold for $150 and considered a good deal if you can fix it, when just 3-4 years ago I bought a 8GB model for just £100.
what do you think a second hand rx580 would cost? prolly around 80 dollars right now..
The "liquid" that you thought was spilled on it might be the thermal pads leaking oil. I have seem many cards that have those marks and they were from bad pads that were leaking all over the card.
my evga 1070 leaked oil from the factory pads, seems evga goes cheap on those.
Can confirm msi uses cheap pads too. They leak all over the place
Yeah, old pads of that style tend to leak a bit. Normal. If you spot any green crud though, you can be sure it was liquid damage.
I can attest to this, my EVGA 1080Ti ftw3 had TONS of that wetness on it when I cracked it open.
They should definitely NEVER use those pads again.
I vape in my room, and the fact that the 1080Ti ftw3 has something like THIRTY of those pads on it, caused my card to die.
I heatgunned it multiple times and that stuff just keep seeping out of the PCB.
I hope EVGA learned their lesson on those pads....
@@badnewsbruner you were kinda asking for it by vaping
The card with the fried Mosfett would still be a relatively easy fix. With the Mosfett removed check the capacitors around it for a direct short. Any that short replace and then new Mosfett should be fixed.

To me, Jonos problem sounds like a grounding error somewhere between the monitor and the pc. (probably the monitor i'd wager) sending electricity where it shouldn't go and knocking it out for a few seconds. I have a similar problem with my USB cables at home, and anytime that my cat goes near my computer something disconnects randomly..
AC power/cables can do this.
Mine was similar one day plus loud noise through my audio. I recently just changed to using a displayport cable to give space for my new vr headset that uses HDMI.
I eventually found that I left the HDMI connected to the monitor, and that the cable's other end was on top of my AVR and power switches. Moved the cable out of there and all blackouts were gone. Havent removed the old cable yet as I'm testing out some other build.
I had a problem like this with a DP cable that has the power pin connected.
Throw the cat away, it's a problem causer! 😉... 😂
It could also just be the display port controller in his monitor. We have similar problems on our notebooks with docks from Lenovo. After some time they start to blank the screen to black in some interval. Lenovo issued several firmware updates for the dock which makes this occur less often. The solution is always to undock the notebook and remove power from the dock for 10s as this resets the DP hub chip.
I would be willing to bet it was the cable between the monitor and the GPU
Interesting video and a lot of good tips, although it would've been nice to have some sort of outcome summary at the end
You can deal with differential traces by re-routing the whole path (where possible) from A to B for paired matches on a daughter board. Have a friend who did this several times and it works. Best part is, the daughter board can be a discard flex cable of the same value route this also matters). If this path is obstructed through the board, not a surface path, your chances for making it work go from "possible" to "mission impossible". In short terms you have to have a good microscope, measuring means, and lots of soldering skill, because even that counts.
24:32 I could have used one of those when I bricked my card with the wrong bios! It was years ago, I had a r9 270 I was having issues with so I tried updating the bios. Turns out Techpowerup doesn't always label their bios correctly, they had a r9 290x bios on the r9 270 page. Always double check your bios before you flash it
yes if the manufacturer doesn't offer an update be careful downloading one.
Techpowerup gpu database is user generated so faulty bios images could get on there.
if this happens you could also try running the card as a second one and have the main one be from the different team, that way it is more difficult to accidentally flash the wrong card

About the Solder Stove Repair: I did it while with the infamous Nvidia Series which didn't had flux at all and bad crystalisation Problems: You heat up to 50°C then to 80° when it reached it you shut the stove off and wait till it reached about 40°C that solves the crystallisation problem and helps for the Cracks. When it works again replace the thermal paste and it is good for some time. The solder cracks and crystallisation problems comes from uneven heating and cooling. So keeping the card better cooled may keep it save for 6 month to 1 year. Without renewing thermal paste: 3-4 Weeks.
I love these repair videos. Its always good to see abandoned tech brought back to life. Y’all should do more!
I wish there was a channel dedicated to this. Awesome video
Flux isn't required for soldering, it just makes it work a lot better, so reflowing works. And I've recovered a dcdc charger that had a full glass of rum and coke spilt on it then was used for another week successfully. Water damage isn't always the end
They sat they bought these GPU's, deep down we known Linus just dropped them all one too many times.
Hey, i have some info that might help. If there is a short between the 6pin or 8 pin (or even the 12V or 3.3V pins of the pcie connector) it's very common that the card has a broken phase, in particular mosfets are the ones who fails the most, and you can test them probing the two sides (if i remember correctly, you have to probe between gate and source but i'm not shure). In that case, you have two options: replace the mosfet with a heat-gun or just cut off that phase by ripping off the broken mosfet. You have a chance that the chip is still alive, and if you choose to cut one phase the card will work but it will have some stability issues so you have to downlock it (it depends on how strong are the other phases). You can also try to make the remaining phases a little bit stronger by adding some capacitors or replacing the inductors with bigger ones. Anyway, hope I was helpful and I loved this video! (PS, the 1080 probably crahed because the broken mosfet doesn't make a short, but it's still not working so the card doesn't have enought power under load)
From what I remember: Low side mosfets usually also fail open while higher power mosfets usually fail short.
So I can assume that the failed mosfet was a low power one that failed open and so didnt cause a short.
@@ayuchanayuko Thanks a lot! I didn't know that
As someone who currently works in electronics assembly i can tell you a few things about the boards you should know. the video card with the ball of solder on the sideof the resistor is a normal process thing and is usually left here as it doesnt hurt anything. the "mossfet" blowing up you would be better off getting that off the board and just bridging it. leaving it on there you run the risk of the power going down the signal line. the "hail mary toaster oven bit" has real merit if you can control it well. typical leadfree solder melts at 221C leaded is 183C there are lowtemp leadfree but those are not usually on performance electronics. Optimal oven process 230c 45sec in a nitrogen atmosphere. This should be enough to Reflow the solder yes thats the correct jargon. If there are BGA parts on the board they need to protected from collapse _this is the biggest risk here. The nitrogen will prevent the oxidation due to missing flux. also leadfree solder is at risk for tin whiskars.. that is a huge conversation all by itself. aerosol pcb cleaners are your best friend here. soft brush and air to blow dry. have fun getting zapped!

Great segment! I really enjoyed learning more about the digital side of circuitry. I have a basic background in electronics. And what I like the most, was how you got right to the bones of the caus/ problem. You addressed when you should give up and why. I was very intrigued to learn caps, had to be equal distance away from the terminal. & probably best to leave that kind of fix to a machine or a professional perfectionist.
I would very much like to see more segments about fixing computers, boards, & electronics in general. Perhaps you could add it to your upcoming test channe or do more of them on this channel. I could probably find a channel like that, but I usually tune out when it gets too technical & drawn out.

The fans typically won't spin unless the card gets hot enough, i.e. when gaming on heavier titles. Try to see if they run while gaming as that would indicate the card is working normally.
