Did the same thing this week with a 3060. It had gotten so hot there were burn Mark's and factory flux everywhere. Found shorted mosfet, replaced and I can't believe it actually works. One very fortunate kid.
I thought i was watching @northwestrepair for a moment 😂 Nice repair Sorin!
Same lol
he is more strong than north>> honestly sorin can give you the whole image of how to repair very quickly easy to understand other channels more serious little details
There is a "slight difference" tho :D NWR is far more professional on GPU repairs.
NWR is not showing us the multimeters and the power supply voltaje like Sorin does. Also Sorin explains much better the fault.
@@ionix2000dumbest comment i've seen in a while
5:40 "NO Keyboard Detected! Press F1 to Run SETUP" thats the best trolling ever in the computer world... 🤣🤦♂
Thats first thing you disable in bios halt on no errors.
🤣🤣🤣🤣🤣
yea, and press the "ANY" key :D
@@icommandoi145I pressed the power button and nothing happened!
disable this sht which some idiot invented in past
This is one very lucky customer!
Yes, still an expensive card.
Hahaha nice one Sorin, GPUs take away heat very quickly thats why you won't see much on a thermal camera but i would prefer that method of yours of grounding the side where the current leaks through a short, that way the faulty driver will produce more heat. Also on removing the driver its better to preheat the board because the gpus take a lot of heat. The gpu dont die after a drmos gets shorted because the drivers on the GPUs are controlled by a very intelligent chip that grounds power or sort of produces a short before the gou core and thus preventing the core from getting bust. What usually kills the gpu is injecting power using a psu hahahaa those if they see a short they pump current into the short. I would like to see a vram case now, thanks Sorin.
I always watch your videos anytime I'm home from work just to learn more. I decided to subscribe for the discord membership plan. And for a week or two that I have joined. I have learned so much more. Someone on the discord channel just helped me fixed my nvidia 3060 laptop that I have given up on for a long time now.
I learn how to fix even without practicing thank you sorin
0:40 We have a nice GPU. Proper nice! Bravo Sorin.
Shorted vcore = good chance it will work Shorted vmem = near zero chance
DRMos, they can short to ground, so the 12 volt going to ground, not GPU. You should really get a board pre-heater too. Well done thou.
I thought i was watching @northwestrepair with A.I. voice again hahahah ! Keep up the great work Sorin !!!
Thanks!
"we have a bit of a heatsink" 😂 You made my day Sorin, haha thanks !
good job sorin as alway...
Great video, nice tutorial, Thanks!
Good job mate
Actually GPU can be burned. To be sure you need install Windows, driver and do few stress tests (furmark for example). GPU can hang system when you try to install the driver. Without tests you can't be sure it's working or not.
except that it doesn't look like bad heat pattern I believe, you can conclude that the gpu is running and doing something when the heat spreads unifromly on the die cover but if it's like a small dot you know that something there got shorted and is consuming all the power as heat.
Northwest repair is going to spoof Sorin again! Lol. Love both you guys. ProsZ
i have repaired few years gpu in msi ofiicial service guaranty, 99% gpu live after short mosfet ;)
Sorin this is like a 12+ layer pcb with huge copper planes, you cannot work on it properly without a preheater/hotplate of some sort.
He can. Will it be easy? No, not at all. But you can work on it. Of course replacing bigger stuff like memory or die will be impossible but everything else is doable.
@@gorjy9610 its doable but as you can see sorin is mentioning he held his hot air for like 10 mins on the card (probably at 400c+) and still nothing was melting, which is not good for the on board components and the pcb taking the heat.
That's amazing! (I am pretty sure I know the exact intonation you've just vividly imagined 😄)
You have to take the back plate out before using the heat gun, it has heat pads that suck the heat to the aluminium backplate
@northwestrepair come see Sorin Fixing Gpus, next time Sorin will Reball core
hey Sorin, i am also getting into gpu repair and i can tell this.... you need so much crazy heat to remove even tiny components from a card.... always use a preheater big enough for that board you will keep your sanity that way and not overheat other components, especially if you done a leaded solder reball on some parts
I'm worried what will happen to the mosfet with 140C solder, when the GFX is stressed and Temp rises
Yeah - don't think 140C low melt is a good idea - back for warranty repair soon!
Most of the transistors won't survive junction temperatures over 125-150C. So, it won't survive anyway.
the solder will get liquid 7:58
the 140 solder is mixed with no lead solder 220 original from board , so the result is higher than 140 so it is probably safe, but i would have used 180 deg solder.
@@user-vp7ri7yl6y In the factory they use like 240C degree profile for reflow oven , and there the whole board reaches that temperature.
afaik low melt (bismuth based) creates brittle joints if I'm not mistaking and supposedly even much worse when combined with lead (already present or added lead based solder). Additionally even if the melting point is 140° - the alloy might start softening at a lower temp (~ic working temps) which increases the possibility of rapidly accumulating vibration cracks (because in theory it won't reach the melting point and mend the previous cracks) No disrespect but i think this not good practice.
Exactly ,finally somebody does mention this stuff. Low melt solder is mainly good for desoldering stuff, but not for soldering.
My PC with MSI GTX 970 turned of while playing with smoke coming out from case. I found out that one of the mosfets was basically welded to the board. I took the mosfet out of the board and replaced with new one. With not much hope i put it back if it will work and it was. That GPU still works in younger brothers PC. Amazing what GPUs can handle.
What's perfect repair !
very good
It's a good idea to use a heat shield for the capacitors as they don't like hot air. An L section strip from a soda can will do.
Not sure but I believe this chip was partially working and able to measure the current using the shunt resistor and cut the power on the GPU and probably it was switching the low side first for testing or something of the kind , because whatever got shorted it must be the high side mosfet I mean it must be having short protection mechanism otherwise the survival of the GPU is inexplicable...
Sometimes need to check mosfet output with scope, maybe chip fake or not good solder... becouse we've seen it works also without it
...and the short is gone!
Mr. Sorin, do you have any advice or tips to visibly know if a chip is fake/counterfeit? Before ordering that is... YOU ARE AWESOME!!!
And the GPU fix is guaranteed for how long?
Super=)
but what if gpu isnt displaying and pc booting normally? i have that issue with a gtx 1070. but when it does display it will work flawlessly. any ideas Sorin?
You need to test it to see if everything is running as it should. Most of the time it isn't so easy as you show it here.
Do you it is possible control bios as a elctronical
The dislikes are from GPU manufacturers
its so sad that a high end expensive gpu doesnt have fuses on the 12v rails, you can install fuses by lifting the coils and soldering a fuse between the coil's leg and the pad, thats how you make a better than factory repair.
5:09 i will NOT recommend this GPU raiser its doing alot of errors and most of the time no Display at all, i recommend ThermalTake Premium Raiser
Bon sorin yees
❤❤❤❤
👍👍👌👌
Hi Sorin Iam very Keen to Know your nationality !
GPU is not dead because PSU power detect issue and disable. If you inject above 1v, killed GPU.
you do understand that a big PSU can push 50-60 AMPS at 12V, so even with 0.2 ohm resistance its happy to pass all that current. its not gonna detect anything unusual.
Probably he could inject more ,and do not kill the GPU, since he was injecting at 12v rail. At the DrMos (Vcore) the short is grounded , and only a small leak of current is passing by , resulting the die getting "warm".
@@batizbalint9947 of course that's very different. when he says mosfet is shorted he means passing input to output. easy to verify with multimeter once off the board
Hey Sorin. You should have created this video with an AI voice over as NorthWestRepair. You know exactly why I said that 😁🤣😂 Anyway, yet another great repair video 👍
you clean the rosin 😒
where's the cpu heatsink? 😂
@@EarthSouthside yes but, more test is required I guess and it's 9900K, the first Intel i9 ever
@@EarthSouthside very very very hot
I don't believe much this repair...
Top banana 🍌
First :D
First
Hmmm its kind of a fix... I like to watch NorthWest repair he works only gpus and all 3090 are bad... I wold personaly use higher temp solder and preheat the board also i would run MODS to check memory and a stress test.
why?, there was no fault with the memory.
@@mart43 Because you allways trust the customer... NOT... and so you can say it worked for sure and stop posible refund and/or shiping costs also time etc... And how else will you know if the temps are right...
very soon another drives ill die , most likley always replace all same time.
thats a different job.
Thanks!
