Thank you so much, I have the exact same card, same issue with causing a short circuit- your method of removing the coils to isolate the faulty mosfet was fantastic! I removed the coils and found the short, removed the supplying mosfet and have the card back up and running- of course it would be better to replace the mosfet, but that is beyond my ability, and the card runs at least for now and maybe until it's possible to buy a graphics card for less than the price of your first born child, one can hope. Thank you again!

nice video, very interesting, great job. Strange choice of the owner of do not restore the missing phase, I think it could damage the other 5 phases, like this they work overloaded!
Sir, your method is very unique from other youtube tech I ever watched who repair GPUs. GTX 970 will rock for many years to come! Amazing! Ofigenno! Your method blown my mind! Udachi! From Philippines with love!
Thank you. A proper way to find a faulted mosfet is to use a thermal camera. Also i had to check gates resistence but i didnt do that. Soldering iron is quite new and it is from China:)
@@electronicshaverightstolive I agree Sir. A vlogger named NorthridgeFix from California even emphasized the use of thermal camera to find faults on laptop boards and video cards. Sadly, thermal camera here costs as big as gold bar even though China is just a small sea away from us. But verily a wonderful tool to use. But the technique you shared here was really a good promising start for new technicians who want to dabble in video card repairs. In my city a lot of laptop and desktop computer technicians go away from video cards because of high failure rate, like repaired today but might fail tomorrow. And the parts too looks hard to find even though it can be bought online if donor boards are hard to find. Somehow this technique you shared is promising when it comes to isolating where the defect may be.
Thanks a lot for the video and info i learned a lot. I got same gpu it has no picture fans spins and core is cold. On pci first 3 pins have 9K oms and ground has 0... but i tested on working gpu and first 3 pins on pci express give me the same 9k oms so i dont understand
@@electronicshaverightstolive yeah but all mosfets have resistance. And I'm not sure where to correctly check voltage when card is turned on. But where i checked its 10v on 3 sports and on 2 spots 2.3v. Im noob hehe
Thank you, it was awesome for teach us,, i would like to ask, I found one of source low mosfet is not connected to the ground, could we just jumper it? or keep searching another else? and one more, what component in GPU Board look like Square box, there is text CE 1R0 above with grey color, I couldn't find it in google, Thanks for help, Ikram from Indonesia
Thank you. 1R0 is 1 Ohm resistor. I suppose it is a current sense resistor or something like this. Probably it has blown, thats why you dont have a path to the ground.
Thank you, I have fixed my MSI 970. The faulty mosfet was the top one. I managed to boot up with the card BUT it burned out again under load. Another component can burn the mosfet, maybe the controller?
Nice video, actually usefull video , i got a 970 that i want to revive as well ! Mind telling me if the pc fan worked or refused to even turn on when when you tested this card before repairing it?
Thanks. Actually i didn't try to power it on since i always check power rails before turning anything on. And sure if you have a short on the 12 volts line your pc fan should not work since your power supply goes into protection mode.
Power supply goes into protection mode due to a short circuit on 12 volt line of the card. So all system and obviously the card behave completely dead.
@@manISnoGOD probably your paste has lower temperature transfer ratio or you did something wrong when doing so. Not enough paste, didn't tighten screws enough etc. A missing cap can give some problems to voltage stability but it is not gonna be the reason of higher temperature.
Usually we should put the tip on the high side of the coil or sourse of mosfet. But this time i put the tip on gate resistors of mosfet. It was more convinient
I loved this video. You're very thorough, clear and such a good teacher!
Thank you for taking the time to make this!
You rock~
Thank you for your good words!

Thank you too!
short but really informative, i love this video!
it's not actually short lmfao i just checked it's like 26 mins but guess it went by in a flash cuz i was too into it XD
Thank you!

Core is cold.. Probably you don't have voltage on the core.

Great, good job.
Thanks
Next video with so easy repair..
nice video but if you edit it more it will get alot more views
There is a faster way to check which mosfet is bad using the multimeter without removing all coil and don’t spend that much time or voltage injection
What is the way, tell us please?
@@electronicshaverightstolive since the gate is shorted too, you can measure this in circuit to identify the bad mosfet
Thank you, it was awesome for teach us,,
i would like to ask, I found one of source low mosfet is not connected to the ground, could we just jumper it?
or keep searching another else?
and one more, what component in GPU Board look like Square box, there is text CE 1R0 above with grey color,

How do you know so much about so many electronic items? Great troubleshooting job
Thank you. Basic electronics can be applied to every electronic device at some extent. Usually it is enough for repair half of the problems.

Hi Can You Upload More Repair Videos please
Hi. I will try. But now i dont feel myself very good. Probably catched a cold.
please make more gpu repair videos
Excellent video! What is the consequence of losing a phase on such a graphic card? thx
Thanks. Consequence is an inability to use graphic card at full power and higher probability damaging other phases.
@@electronicshaverightstolive ok then I'll try to add it back cause my issue was precisely the same
Hi!! May i ask what was the symptoms of your gpu before you removed something? Thank you!!
@@blaupunkt08 first I had tearing and artifacts, and afterwards the PC could not recognize it.
Can i ask what was the symptoms of the broken graphics card before it was repaired? How does it behave before? Thanks!!
Power supply goes into protection mode due to a short circuit on 12 volt line of the card. So all system and obviously the card behave completely dead.
heelo, are you sure the R005 is the fuse at 10:27? 0ne of my 3 is 0 ohm the other 2 measures OL.
Okay I see at 12:06. they are current sensing resistor. Thank you so I know 2 of them are Dead. Thank you
Can I just Bridge them out?
Do you have anything were i can contact you because i have the same gpu and everytime i plug the vga into the pin it turns off my whole pc

Where I can get data pcie x16 socket, & how type clue ini google for name?
You can buy it at Aliexpress.
@@electronicshaverightstolive I mean data printed you have
good day can you explain me after fixing my gpu a cap blown off but now its still working but its getting hotter then before the cap blown off
Hello. Did you remove thermal interface (heat sink) after the cap blew up?
@@electronicshaverightstolive yes i remove and add new paste
@@manISnoGOD probably your paste has lower temperature transfer ratio or you did something wrong when doing so. Not enough paste, didn't tighten screws enough etc. A missing cap can give some problems to voltage stability but it is not gonna be the reason of higher temperature.
@@electronicshaverightstoliveI use coolmaster paste the cap was near the 12v PCI Express pins the 3 12v
with the tip of the oscilloscope you put where to measure the phases?
Usually we should put the tip on the high side of the coil or sourse of mosfet. But this time i put the tip on gate resistors of mosfet. It was more convinient
you know sm7320 alter mosfet ?
Alter? What exactly do you mean?
