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.

And they had problems too

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.

Жыл бұрын

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.

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.

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?

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

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?

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 had the same card and did the step up/swap to the FTW2 - I did do the thermal pad fix first

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.

I don't know a lot about GPUs, but when you mentioned it being time based on PCI-E, sounds like it's impedance controlled. That means any change to length, type of connection, or even the soldermask on top of it will affect the response times. If it's really like that, then it's most likely a goner unless you have some sort of copper welder for traces (which are half a million or more for the super special ones we'd use for my line of work).

6:32 I once had a huge short in the ATX 12V connector on the top of my mobo, and it didn't blow my Seasonic PSU. It was a zero-Ohm short but the thing was intelligent enough not to burn itself.

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 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 liked the episode, good stuff. There will be plenty of used mining GPUs on the market after the Ethereum merge I would imagine.

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 :)

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 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.

17:50 I had an 8x card that needed to go into a board that only had a 4x slot. Just took pliers and broke off 4 of the lanes and it worked a charm

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.

@SineN0mine3

2 жыл бұрын

@@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 love watching videos like this. Seeing people troubleshoot GPUs and finding one dead component like SMT resistor or capacitor looks like wizardry.

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.

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.

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.

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.

Fixed a few old AGP cards with blown caps and they are all working fine...except an old Sapphire Radeon 9200 and 9200SE - overheated the DRAM while replacing caps near it due to heat flowing through ground. Not a huge loss as the SE was a terrible card and the 9200 one of the slowest 128bit versions.

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.

literally just reminded me to update my driver so thank you!

This was great,Id love to see more attempting to fix dead cards etc,Especially more exotic and weird cards like Quadro,Titan,Radeon Pro etc.

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.

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

20:27 Oh hell yeah. Zip tying a noctua to anything is always effective. 23:01 Oh yeah. That's a classic. Desktop sits on floor under the overhang of the desk, and a drink spills on the desk and pours directly into the top of the case and onto the graphics card.

So much of this video is so incredibly satisfying. ❤️ Solid content!

As if Luke fixing a dead CPU was bad enough. Leave it to Alex to take on the hardware jobs no one else at LMG would.

Jono's problem can easily be HDMI cable breaking... I had similar issue with my gpu so I swapped the cable to ps4 and then PS4 had the same issue so I replaced the cable completely... It also can be monitor firmware that also happened to me with brand new hdmi cable Or it can be caused by wrong setting in either monitor settings or gpu driver settings... Without his exact setup it's impossible to tell

My 1660s would not output anything untill it hit the windows login screen, so i couldn't access the bios menu. Swapping the cable fixed it and the cable looked slightly bent at the monitor end plug. Why windows could use it and the BIOS could not, I don't know.

Updating monitor's firmware ... damn never thought you can do that! None of those cards should have been bought though, it should have been a throw away pile sent only for shipping costs or at best a few bucks for the hardware value. Great video.

Interesting video and a lot of good tips, although it would've been nice to have some sort of outcome summary at the end

2:33 Is that a black eye there on Jono?

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.

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.

In my experience, random crashing with GPUS is often caused by old thermal paste. Sounds too simple but I've been surprised too many times now. Even though the temps were fine.

Really awesome video! As a electronics technician this was super interesting, as I usually only work with custom hardware. I would really like more of Kyle in the future :)

Fun video! I'm glad you made this because I always wanted to do something like this and clearly it's not worth it. I also thought about buying damaged CPUs (AM5) with missing pins and having a jeweller solder on new pins. I wondered how cost effective that would be. You should do that next! I used to design video cards. I have one comment about the dead MOSFET. The MOSFET of a switching power supply cannot be shorted to test because these Switchers usually swtich from a higher voltage to a lower voltage (buck converter). If you short the high pulling MOSFET, it will tie the higher voltage input to the lower voltage output and kill what ever is attached to it. For example if you had 12VDC from the GPU power input, switching down to 1.5V for Memory, then 12V would short directly to the memory and they would all go pop! Please do not short across MOSFETS. If you find a board with a shorted MOSFET to the high input voltage, chances are other chips are dead. However, if you find one that shorts to ground (the low side MOSFET), you can often replace those and get things working again. Soldering them is tricky because they have large metal slugs underneath that have to be reflowed to remove and install the new one. They are really tricky and you need a professional rework technician with specialized tools to have a chance of doing the job right.

A hot air rework station ought to do it. But of course, you don't want to dwell too long or use too high a temperature. It's like a localized reflow oven; just make sure to check the datasheet, if available, for the max dwell times at given temperatures.

6:45 That's some next level turning it off and on again

Components that "just" have been under water can mostly be repaired by just cleaning them. A friend of mine had a flooding in his area and his office was halfly under water. All of the computers were full with this agressive mixture of water, mud and whatever came up from the seweage. Luckily almost all computers were turned off. I took them all apart (wearing gloves and a mask) and cleaned them with disinfectant, dish soap + distilled water, using a brush and finally some fresh distilled water again. The cases were cleaned with a garden hose and disinfectant. I didn´t open the power suplys, because that is dangerous, but some of them were just above the water. I let it all dry for a week and put them back together. They almost all worked! I just needed to put in some few spare parts.

12:11 Short circuit > blown MOSFET > blown fuse (probably exist) and everything else is fine. For best case sceanrio, there is a fuse / choke for each phase, then even the card is work in some level.

With the watercooled card, sometimes there is anti-corrosion chemicals in the water (to prevent the corrosion from 2 metals touching in water, eg copper and aluminum). That chemical might have leaked onto the board if the water-cooler had a break and leaked.

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.
