Now I take this channel like a wiki for me! I just search the channel for macbook pro.. and I see some list with lot's of issue resolved. That's a goldmine of information :) , Jazakallah to Alex! the creator of all this video..!
You found and replaced a shorted capacitor. The short is now gone. The 12V does not come on whether the involved components are in or out. Then you have to move to another place on the pcb looking for the problem. Disrupted pcb track or protection series resistor. In this case you have donor cards you can use for comparison - makes your odds high. Tx very much for your efforts in making these videos, highly appreciated 😊
The time you post your videos mean it’s one of the first I see in the morning here in the U.K., making it a great start to the day. Another very educational video, thank you.
Sorry to see a no fix after you have stayed late. Wanted to see your yes, I fixed it smile which would have made it more worthwhile for you to have stayed late. Better luck next time.
I also do repairing and 50% of it I have learned from this TH-cam channel Thankyou Alex for consistently posting various types of repairs. Love from Goa, India.
A fresh mind in the morning might help. Not every fix is going to be easy, unfortunately, however, the way you go about diagnosing problems helps us come to an understanding of how things work, thank you for that.
Loving the open discussion on this chat and how the conversation comes across... Suggestions without condescension. A credit to Alex for being approachable and open, and to the supporters / techies for remembering that we are always learning!
Video cards seem to be the hardest to fix, more time might be a good investment, to figure out they're failure commonalities. Great work, thanks for sharing your vast experience and knowledge.
If you have 12v on the card input I would assume that the 12v are not being shorted. If 12v arent reaching the chip then I'd look for an open coil, fuse or resistor along the path of the input and the the 5v chip.
Hello @NorthridgeFix Alex, from what i've seen i think you have a partially shorted component since its measuring 0.200V , since you have on the chip 3.3V Enable shouldn't be a digital problem, and having 5V vcc, you could supply with your power supply on that big CAP that you changed the 12V that you need on that output and the bad component should get HOT, also max current 1A on power supply to be safe. Good luck and i hope you'll be able to fix it , can't wait for the next video.
I have faith you will figure it out after a good nights sleep. Loving your videos I cant tell you how much your videos have educated me over the years. Thanks Alex
your knowledge of all these video cards is immense. looking forward to part 2 of this video. If there are no shorts then it must be an open circuit on a resistor somewhere maybe?
You know so much about videocards right now. Its amazing how human learn so fast when they do something that they are interested in. Thank you for the video, hope you will find the error soon
No 12v input is going in, the shorted cap caused a fuse to go open somewhere, gonna have to find that fuse, probably near 12v rails from power connector or the pcie slot. Also a riser cable would help alot in your gpu repairs.
Another graphics card how wonder how much of a dent Alex has put in to the pile of them .Another great video keep it up .I always learn something and enjoy it everything.
Alex. i thank you so much for all the nice videos its a good learning from a men where i have RESPECT for. also all the viewers thanks. Every day i looking and learn a lot. thank you from the Belgium Coast. R E S P E C T. for you and the family there..... grtz Alain and sorry for my bad english
Love watching you work ive started to fix xbox one and ps4 from watching you. So thankyou for all what you do and hope you keep on doing it for a long time to come.
A moment of silence for the fallen GPU ... anxiously waiting for part 2 Disclaimer: I am no EE and don't even have the slightest idea of what you're doing. I just found that your repair videos therapeutic. That and you're a great guy
The method you use to find short in diode mode. I watched some videos you using that method. I tried it on a detection circuit board on a machine I've been troubleshooting, the 12V goes to zero. Using the diode mode I found a shorted cap. I removed it the short is gone. Thanks Alex for the tip and your knowledge.
Check the gs7133 or gs7103 it is a regulator from 12v to 5v it must be on the part behind the card near the 12v pci, This supplies 5v in low consumption mode to both the card and an hdmi port, check if the chip of the hdmi1 port has 5v. Revisa el gs7133 o gs7103 es un regulador de 12v a 5v debe de estar por la parte detrás de la tarjeta cerca del pci 12v, este suminestra 5v en modo bajo consumo tanto a la tarjeta como a un puerto hdmi, revisa si el chip del puerto hdmi1 tiene los 5v.
you should measure the input voltage for that step down converter iadg befor replace it then go over the 12 v line with continuity mode to know the 12v coming from where
Missing 12v on to the 5v regulator. Bad fuse or 0 ohm resistor. The 0 ohm resistor is likely 1/2 watt and the shorted cap blew it with a silent sniper shot right to the 0 bullseye..
Alex on the back side, Look for a IC 505 it is 40 leg ic. nier that ic u should find two 0 ohm rezistors/fuses Check if they are ok. 12v_F and (12v_pex_misc have two caps on the way 0.1uF and 22uF) should have direct path to Pin nr 2 If u have no 12v then fuses blown. Fuses marked r1007 and r987 12v_F is goes pass R987 0 ohm rezistor/fuse. I have documents that i cant share. Due to ............. some ones knocking on my door, i think nvidia guys with black glasses.. GTG :D
The problem is that 12V in is missing, nothing to do with the chip. Probably a (low ohm) resistor on the board, find the point (beep) on the board where 12V is feeding the 5V regulator.
Sometimes all we need is to move away from the issue and come back later 😁 I was going to suggest track the path to the 12V input but the answer has already been found...maybe next time...
As nice as the founders edition cards look, I tend to go with a different card due to the FE cards having a lot of issues, especially with heat and noise. Hope you get it fixed. waiting on part 2.
great videos love watching these from Australia! I'm just starting a new business in phone/ electronics repairs and this has been invaluable i have learnt so much even tho my tools a very subpar ( i don't even have a soldering iron/proper amp reader,i don't even haave a hot air station,microscope just a little eye lense ) i do what i can with the tools i have! i'm slowly learning so much more! unlike a lot in aus i wasn't able to finish high school due to a chronic illness so i have never been able to pay for a course in electronic etc even a phone repair class in Australia cost more than 5k! once again thank you again all the way in Aus
On your spare parts board if you measure between the cap and the 12v line is it a straight continuous line or is it fused maybe or a small component taken out as though it was a fuse. I would be interested to find out if it was the same reading on both boards…. It maybe it took out a via where the track goes through the board….. But keep up the great work every problem is an opportunity to lear more
There's a chip on the back of the board that regulate the voltage output and input uP511P but also there components that maybe out around that chip which are transitors,diodes and capacitors and with everything being so small it can be a strain on the brain.
If there is no short 12V on step down convertor's input pin, isn't it possibble to inject 12V and see if 5V is there. If yes, trace back to source of 12V.
The amount of knowledge you have on so many different boards is astonishing. Great job!
Now I take this channel like a wiki for me! I just search the channel for macbook pro.. and I see some list with lot's of issue resolved. That's a goldmine of information :) , Jazakallah to Alex! the creator of all this video..!
Whether it's a fix or no fix, you never stopped uploading the video. I appreciate that courage
Going down the rabbit hole is what I find the most difficult. Very good work master Alex. Thank you for the video. Love from Portugal.
You found and replaced a shorted capacitor.
The short is now gone.
The 12V does not come on whether the involved components are in or out.
Then you have to move to another place on the pcb looking for the problem.
Disrupted pcb track or protection series resistor.
In this case you have donor cards you can use for comparison - makes your odds high.
Tx very much for your efforts in making these videos, highly appreciated 😊
When I am working on boards late, it is a guarantee no fix. As soon as I take a break and return the next day, I pretty much always find the reason.
The time you post your videos mean it’s one of the first I see in the morning here in the U.K., making it a great start to the day. Another very educational video, thank you.
its the afternoon for me and watching this is a good way to end my daily task/chores because i usually finish around the afternoon haha.
Sorry to see a no fix after you have stayed late. Wanted to see your yes, I fixed it smile which would have made it more worthwhile for you to have stayed late. Better luck next time.

This channel is very education and people are also contributing their insights. Learning more. Thanks to all.
The amount of patience and endurance to do this job is mindblowing to me. Keep it up
14:59 "I doubt that that chip is bad because I know for a fact that this chip is good". I mean, you can't argue with that.
trust the man
Haha Experience 😜
lol
Another great video ! Love your honesty when your learning a new card, we're all learning at the same time!
Oh I’m currently working on the first GPU I try to repair and it’s a 1070 😊 thanks for the knowledge !
Hope you'll fix it
Alex, to ease the testing job, you can probably buy a pcie riser.
Put back those components. Plug it back in and view it with the thermal cam. You may see the short.
Video cards seem to be the hardest to fix, more time might be a good investment, to figure out they're failure commonalities. Great work, thanks for sharing your vast experience and knowledge.
The ease at which you get these video cards fixed is quite astonishing
I wonder if a PCI-E riser cable would allow you to do more in circuit voltage readings easier. Just a suggestion.
You should open another channel and teach people what you know, you’re incredible.
If you have 12v on the card input I would assume that the 12v are not being shorted. If 12v arent reaching the chip then I'd look for an open coil, fuse or resistor along the path of the input and the the 5v chip.
I love when you post GPU repair videos, they're my favorite!

Even I'm not in this business I love to watch your videos for extra knowledge . Thank you sir
It still amazes me to watch you work with these microscopic components.
I have faith you will figure it out after a good nights sleep. Loving your videos I cant tell you how much your videos have educated me over the years. Thanks Alex
I am getting experience on graphic cards through your knowledge thanks alot. I now call you an "ELECTRONICS DOCTOR"
Sometimes it's hard to know if anything on a complicated electronic device works at all. Great effort.
your knowledge of all these video cards is immense. looking forward to part 2 of this video. If there are no shorts then it must be an open circuit on a resistor somewhere maybe?
You know so much about videocards right now. Its amazing how human learn so fast when they do something that they are interested in.
Thank you for the video, hope you will find the error soon
The 10 series was an absolute beast :D
Northridge fix you are the best 👍always keep surprising US. I'm from India🇮🇳 North East. Manipur
No 12v input is going in, the shorted cap caused a fuse to go open somewhere, gonna have to find that fuse, probably near 12v rails from power connector or the pcie slot. Also a riser cable would help alot in your gpu repairs.
All your videos are amazing and the way you work is amazing. I follow all your videos and learn every day.
The experience talking right here , god bless u and ur fam , pass the salam to big boss from Algeria ❤️
Another graphics card how wonder how much of a dent Alex has put in to the pile of them .Another great video keep it up .I always learn something and enjoy it everything.
In Each Graphics Card Video, There's Different Problem, And That's How We Learn How To Solve Different Problems.
Best Informative Video.
That's why we need board diagram and circuit diagram,
Great work to trying to fix device.
I hope it gets fixed. We wanted to see those smiles after a repair is done. 💗
Alex. i thank you so much for all the nice videos its a good learning from a men where i have RESPECT for. also all the viewers thanks. Every day i looking and learn a lot. thank you from the Belgium Coast. R E S P E C T. for you and the family there..... grtz Alain and sorry for my bad english
Another great trouble-shooting video. Eagerly awaiting the follow up to this vid. Thank you Alex.
Love watching you work ive started to fix xbox one and ps4 from watching you. So thankyou for all what you do and hope you keep on doing it for a long time to come.

Congratulation Alex, you are doing the job very delicately, very precisely, like an expert and always "Better than factory"... 😊
Every day I always wait for your videos to learn more, Greetings from Dominican Republic 🇩🇴.
Meter in Diet mode(it works 24/7)! Alex you are great keep up the good work.
Salute from Greece
Hope there will be a part 2 on this. Knowledgeable video. Great job!
Interesting, Alex will have the board schematic running in his mind when sleeping. I hope you will find the solution.
Waited for the smile after the fix but......
Eagerly waiting to see that in part2
You are genius,..you have knowledge of every device. either its iphone ipad laptop or gaming card.
Check the gs7133 or gs7103 it is a regulator from 12v to 5v it must be on the part behind the card near the 12v pci, This supplies 5v in low consumption mode to both the card and an hdmi port, check if the chip of the hdmi1 port has 5v.

Anxious to see part two of this card, and am certain that Alex will find the solution too.
I don't know much about electronics repair but this is interesting to watch regardless.
I hope to see you fix this video card, every card has its own issue and this teach us a lot
you should measure the input voltage for that step down converter iadg befor replace it
then go over the 12 v line with continuity mode to know the 12v coming from where
Another great video. It's good to see that not everything can be fixed right away and easily.
the power of persistence... good work
nice to know how to to the repairs on graphics cards they dont really do it here where i stay
Hi, If 12v is not present at the cap you replace, you have big chance to find a blown fuse or resistor, Julien.
Need a part 2 of this video. Great job
Missing 12v on to the 5v regulator. Bad fuse or 0 ohm resistor. The 0 ohm resistor is likely 1/2 watt and the shorted cap blew it with a silent sniper shot right to the 0 bullseye..
Great video hope you and family enjoy your weekend 😀
Love watching u on difficult repairs and it’s fixed
No issues for this next time
Alex on the back side, Look for a IC 505 it is 40 leg ic. nier that ic u should find two 0 ohm rezistors/fuses Check if they are ok. 12v_F and (12v_pex_misc have two caps on the way 0.1uF and 22uF) should have direct path to Pin nr 2
If u have no 12v then fuses blown.
Fuses marked r1007 and r987 12v_F is goes pass R987 0 ohm rezistor/fuse. I have documents that i cant share. Due to ............. some ones knocking on my door, i think nvidia guys with black glasses.. GTG :D
Love your work. would be cool if we could spend one whole day to see what jobs you fix in 1 day.
Congratulations 🍾🎊🎈🎉 to me my very first M92 chip replacement was successful hurrrrrrrrrrry thanks 🙏 for the videos I really appreciate my master
The resistor theory sounds good.
Keep up the great work , the knowledge give to us is always helpful
GPUs look so fun to fix, even if it doesn't always turn out well
The problem is that 12V in is missing, nothing to do with the chip. Probably a (low ohm) resistor on the board, find the point (beep) on the board where 12V is feeding the 5V regulator.
this better than rma and it takes less months to be repaired. huge respect to this business
Sometimes all we need is to move away from the issue and come back later 😁 I was going to suggest track the path to the 12V input but the answer has already been found...maybe next time...
incredible experiences come form hard repairs like this i hope you can fix it
As nice as the founders edition cards look, I tend to go with a different card due to the FE cards having a lot of issues, especially with heat and noise. Hope you get it fixed. waiting on part 2.
The 30 series FE cards come with good coolers.
Hi Alex, great video, my guess is the gpu was overclocked so defiantly damage on that chip. i had that problem before with a client's card.
great videos love watching these from Australia! I'm just starting a new business in phone/ electronics repairs and this has been invaluable i have learnt so much
even tho my tools a very subpar ( i don't even have a soldering iron/proper amp reader,i don't even haave a hot air station,microscope just a little eye lense ) i do what i can with the tools i have! i'm slowly learning so much more!
unlike a lot in aus i wasn't able to finish high school due to a chronic illness so i have never
been able to pay for a course in electronic etc even a phone repair class in Australia cost more than 5k!
once again thank you again all the way in Aus
What is this PEX/VEX that you mention? And where is it measured? Thanks for these videos. Learning so much from every single one of them.
On your spare parts board if you measure between the cap and the 12v line is it a straight continuous line or is it fused maybe or a small component taken out as though it was a fuse.
I would be interested to find out if it was the same reading on both boards….
It maybe it took out a via where the track goes through the board…..
But keep up the great work every problem is an opportunity to lear more
Hi Alex....These troubleshooting videos are great, even with no-fix..
There's a chip on the back of the board that regulate the voltage output and input uP511P but also there components that maybe out around that chip which are transitors,diodes and capacitors and with everything being so small it can be a strain on the brain.
Thank you for your time and effort uploading excellent videos for our education, it has improved my skills tremendous...
You always can!! Waiting for part two!!
i like your gpu repairs favorite part of this channel as a gamer
Tons of Knowledge In all of your Videos.
Thanks for your honesty 😍
The problem is the input of the step down converter it must be 12v.
Great video. Its a shame that replacing the cap and voltage step down chip lead to a no fix. I sure you figure it out on the next video. Good luck
Northridge fix!!!! Better than factory
What can I say thank you for every video you upload 😯
Much Love and respect from South Africa
Great video like always.
Learmed too many thing from you.
The best on youtube.......
nice hope to see news on that card repair soon
These troubleshooting videos are great, even with no-fix.
this channel is a treasure of info 👏👌👍✔
Pro tip: take a 9V battery and 2x 1.5V batteries, put them in series and strap them to a train track. TADA 12V rail🤓
If there is no short 12V on step down convertor's input pin, isn't it possibble to inject 12V and see if 5V is there. If yes, trace back to source of 12V.
waiting for part 2, hope you fix it sir thanks for sharing your knowledge again.
What about tracing the Vcc signal from the chip to the 12v source, there must be a failure between them
@@NorthridgeFix
Right it's a multi-layer board not just 2 layers.
Wealth of repair knowledge,jxt waiting for the next 1.thanks
