Bless your soul. You saved this college student thousands of dollars.
Thousands? a 2012 macbook worth 300 these days.....
@@HouseRLS well he probably meant thousands if he had to buy another Macbook. Think outside the box will you 😀
Thank you so much I was a component level service engineer on Acorn computers in the early 90s but not done much with silly small components since then...… Anyway I woke up to my 2012 Macbook pro dead! I followed the instructions on ifixit to remove the board and resoldered the IC. It is now back together and working perfectly. Seriously you have saved me a LOT of money we pay the equivalent of near $3000 for the base MacBook Pro 16" on this side of the pond and my 2012 is still doing the business.
Brilliant - just managed to fix my 10 year old Macbook Pro Retina thanks to your very good instructions (although I'm a layman and only know a bit of soldering )and am writing this message with it right now. I would never have come up with the solution to the problem. Thank you very much, this is just awesome!
Thank you! I did this successfully with a Harbor Freight 100w solder gun. Just filed the tip to a blade like another viewer mentioned. I bought the solder and flux you mention in the comments. I had no soldering experience, so practiced soldering on an old kindle that was headed to the e-waste pile.
Alanna LaBelle That’s awesome! Great job!
I have been looking around for a solution and confuse about the reason this was happening i am able to do some micro soldering but don't know how to diagnose a problem and I found out this was the problem this actually made my day I have been having it sitting in my room for like a year and a half thanks man for sharing this info
Tried it and it worked after spending a month or two to pluck up courage. The comments from people who filed down soldering pistols and the like inspired a sense of recklessness - I did buy a thermostatic iron, no mess flux and an antistatic mat with a cuff.
I made a microscope to inspect before and after with a laser pointer lens on my phone camara.
The video makes it look quite simple - just check out other videos on the same issue to get a broader view.
Sent in my board about 2 weeks ago got it back this past Monday. I installed the repaired board in about 45 minutes powered it up and viola, I have video again. I paid $200.00 for the 2012 15 inch Macbook pro Retina. With the $250.00 repair I now have a $450.00 Macbook. Time to sell my non retina 2012. Thank You Powerbook Medic
Hey, I just brought a precision screwdriver set off amazon, dug out my old gas soldering iron, grabbed a load of flux. Filed the tip down to a sharp blade, 45 minutes later. My Macbook Pro sees life again! Thankyou So Much! i kind of want to smash it through the window of the local apple repair shop that quoted me £2000 to fix my 2012 MBPr though....}
My Hero!
Always happy to hear of success stories! Glad to know this video got you up and running!
thank you sooooooooooooo much. After 3 years my NVIDIA chip works and no more black screens!
Glad to help. That's why we makes these videos.
I fixed my old MacBook Pro with this problem thanks to your video. Thank you for sharing valuable information.
Just brought a whole new logic board to place I myself. Wish I found this video earlier. I looked for sooo long then I find this looking at your account after watching the disassemble guide.
I almost scrapped this logic-board because of a GPU issue before I found this vid! lots of screws but easy fix with the right equipment. I was able to successfully fix this board, Big thanks!
I`ve managed to revive my MBP 15 Early 2013 - same symptoms same solution. Thanks alot you saved me hundreds of bucks!
How many degrees Celsius did you use?
@@tbu_drachenkater5397 350 degrees on my soldering gun as usual. Dont forget the flux also.
@@nistel thanks. Can you explain how to do this repair? The guy in the video just went with the soldering iron from one side of the chip to the outher. But how does that fix the soldering?
@@tbu_drachenkater5397 the idea is to reflow the chip. Add some solder and flux should be enough. If you want the best possible effect you ran remove the chip and solder it again.
@@nistel thanks, i will definitely do it
I did exactly as the video showed and it worked. Thanks man. Saved a 2012 model from the scrap pile. I bought it specifically with the intention of trying this, which was a bit of a gamble, but it paid off!
Sos un genio, pude resolver esa falla despues de varios intentos, y cuando estaba por rendirme justo encontre tu video! mil gracias!
thank you very much for your video, i had exactly same issue with a 820-3332-a which have been keeping as stock for ages, there was not enough solder around this chip i applied some more with led free and its working fine, thanks again
Love you man. I was watching UA-cam and my Macbook Pro Retina mid 2012 turned off and now it's not turning on. I am going to try this method.
did it work for you?
Thank you so much for this video. Followed a link from Tim (TCRS) who mentioned this fault and your video. Believe we are facing the same fault -> logo appears -> see the boot OS bar to about 25% then a flicker -> see the mouse pointer -> then dark. Caps key toggles fine. Suspecting the same fault so will reflow it. Thank you again.
Thank you. What can I say? When I was assembling the computer back I was thinking, such an effort and the bloody screen wont lit... Worse than that, the computer will toast the second I press the power button. I've assembled it and even used all the screws (surprise!). One hand on the switch, another on the mag safe (plan B: if you smell burnt electronics, if it doesn't start imediatelly, Pull the plug. Avoid burning the building). Pressed the switch, the screen came alive, the rotten apple shining and chiming. For a quarter of the price I keep the soldering Iron, the flux, the solder, the screw driver kit, the isopropril alcool, the magnifying glass, the second hand and the knowledge. THANK YOU!!!! It works, and it is quite simple though terrifying. Best regards :)
Vasco Patrício Happy to help!
Thanks for the video and I'll try the same method on my own Retina 15" mid 2012 MBP :). A quick question - what kind of flux to you use and how and with what do you clean the flux off the board? Have a great weekend!
Gave this a crack tonight and it worked a treat. Thanks for the tip!
How does he exactly solder it? It seems like magic... He seems to pass the iron with the solder on it across all the little solders and it automatically puts every individual solder. Is he using some special soldering iron?
The flux is really what does the "magic".
explain yourself here a little bit. please/thank you@@PowerbookMedic
Man, tank you! Thank you so much, you ended a week of desperate attempts...very grateful for your video and help.
THANK YOU!! I just did this and now the computer is working great.
Excellent! Thank you SO much! I'll get my Dad to resolder, and fix up the second usb and the HDMi ports while we're at it.
It should be a piece of thermal conductor, to remove the heat from the chip and to reduce its thermal expansion, which will reduce the tension on the soldering points.
I have the shut down when I plug in an HDMI for monitor or USB drive. I am assuming it because it's making a switch to the more powerful GPU that causes the shutoff?
yeah i think that’s why
Brilliant! Can be the same problem with A1398 2015 dual graphics ?
In case someone else tried this repair and it didn't help: Try putting a bit of thin (~1mm thick) foam on the U7400 chip. This is the similarly sized but slightly larger chip to the right of the U8900 chip. It worked for me. So it could be that my U8900 repair failed, or that the problem is in fact with the U7400 chip, or even somewhere else...I know this is not a proper repair but it works flawlessly now so I'm going to leave it as it is.
Hi Mr Medic. Have 20 years experience in electronics, but have somehow got away with never soldering a surface mount chip 😂. Could you just clarify what you are doing? It looks like - apply flux, melt some solder on the tip of the iron, then simply run the iron over the pins. Is that it? No hot air or heat plate involved? Many thanks, Ben
100% works for my macbook 15 2013 🎉
Hi! I have the same Retina 15 2012 MacBook Pro, it has the same problem, I tried to replace the ISL62882C with ISL62882, but it didn't work. Is there a possibility, that 62882 without "C" is not compatible? I looked through the datasheets, they are basically the same :(
Can you tell me how long this repair takes? Have they brought you back with the same problem?
Any suggestions on what tip to use? And you clean the flux with alcohol but how do you clean the alcohol? Thanks!
Does this also happen in the Late 2013 15" models? I took one of those to a service shop and they completely botched the thermal grease application (as well as other things), the CPU temp went up to 110°C!!, I opened it up, cleaned it and added some fresh thermal compound and it was ok at first but then suddenly I stopped getting video from either HDMI or mini-DP. VNCing into the machine shows the GPU is being detected but not recognized (i.e. it sees an "NVidia Chip Model" with 0 MB RAM connected to the PCI Express), could this be caused by a problem such as the one in this video?
Yes, it actually does happen to some of the 2013 models. Apple has applied an Edge bonding around the VCORE chip which has helped the issue in most units, but some of them still have it. It would definitely be something to try.
Thank you so much man you helped me to save my Mac pro 13 early but unfortunately i damaged backlight keyboard strip whats the solution?
Should I add solder in prevent of this failure? Seems like it just losing power for GPU and can fixed after the problem actually occurred without the extra hardware harm.
Hey ! I did the same thing , someone with experience and tools helped. But the problem persists. When i use a program that uses a lot of gpu force, for ex iMovie for editing, it freezes and doesn't respond until i restard it. Same thing with gpu panic. Any suggestions?
Hi! My MBP 2.3GHz 8GB Retina Logic Board 15” A1398 (after water spill) boots up as expected but extremely slow. Activity Monitor’s Kernel_stack indicates 700% CPU usage. Video display working properly. Same slow symptoms while booting in safe/recovery mode. I assume it’s a logic board hardware error. Any tips to suggest? Thanks
Thanks for the video, I manage to fix the client's macbook. Lifesaver :)
Hoping someone is still out there lol So I am no expert at fixing computers but I tried to follow along with this video to fix the issue with my MacBook Pro. However, after I put it back together it is completely unresponsive now. The light on the charger turns on indicating it is charging but that is it. Even the fans aren't starting up. Any chance I completely killed it by trying to solder that one section? I looked at it with a microscope and it looks as if it came out well. Thanks
gerritian Check to see if any of the pads are bridged. That could be keeping it from turning on.
well, after I did that... and reset the NVRAM i got the same simptoms (macbook pro not booting due to graphics failure) and eventually after 5 minutes everything went dead. I checked mulitple times that my soldering was ok and I had no shorts on that chip. Where can I search for a problem now? Graphics mosfets?
We I still see that the battery is low on the screen if I'm not able to see screen?
I have an iMac my parents have had since around 2009 and the picture is distorted looking. The screen is fine and it runs perfect, how do I fix this?
The iMacs are notorious for having video card issues. Most likely yours is going bad. You can go to our website, type in your serial # and it will give a list of parts including the video cards available for your model.
I have the Mac that you did the video about, mid 2012 15" Macbook Pro, model # 1398, nice machine until the dreaded black screen issues.
Being a Pro Audio Technician myself, semi familiar with surface mount technology component level troubleshooting and repair, I followed your video to try to service my Mac. I do believe that I'm following the correct path as I did see some change in black screen instances after attempting to freshen the solder around the J8900 chip listed in the video.
However, I am not equipped to do this work at home. I bought smallest tip I could find for my Weller Soldering station, and have a 10 power eyeglass, I cant see the IC Chip very well, or tell if my solder joints came out alright. But now the machine wont boot up at all...:(
Apple wants a $750 flat rate for that model, a guy could buy a whole different Mac for that.
Curious if could send either just the logic board or the whole machine to you for repair. I bet you guys could fix it quickly as I'm betting the trouble is right where the video says, although, could be something else.
Let me know rates/fees, turn around time, shipping address, etc..
Thanks
Chris T Yes we can take a look at it for you! You can send just the logic Board and it’s a flat rate of $249.95 for logic Board Repair or if you send the whole machine it is $344.95. You can visit our website www.powerbookmedic.com to schedule the repair.
Hello again. What software are you using to open 820_3332A.brd file? I whas tried OpenBoardView unsuccessfully for this file, but ok for 820_2523.brd. Landrex Test Link opens well, but is really poor in resources.
Julio Baffa I only use Open Board View, so I am not sure why it’s not working for you. Maybe the file is corrupt?
what if your macbook screen goes black when you use an app that utilizes nvidea, keyboard still lit, but if you plug into external monitor, you get display there. Shutting down and restart, screen comes back on. Early 2013 Macbook Pro w/ nvidea.
Good day, am having same issue but am currently in Ghana, I don’t know how to fix it or who can fix it mine is Macbook Pro A1398 2012 Retina..
Hi the failure is detected by testing motherboard or some software? My macbook pro mid2014 15'' no failure in D diagnose and no failure in Techtool, symthoms is already same, the problem is very common? I'm afraid it's the GPU thanks!
The software won't always detect a failure. For example when the GPU Vcore chip is going bad it will output the correct voltage and then all of a sudden drop which gives an error in the software. However if the voltage doesn't drop during testing then there won't be an error. It's possible that your GPU core IC chip is going bad as well. It’s not nearly as common on those models but is still possible to happen.
Will this work on a mid-2012 MacBook Air bc my computer boots normally then after awhile then it makes the checkerboard on the screen then turns off.
How many degrees Celsius did you use?
I just turned MacBook Pro retina 15’ in they said it’s Graphics Processing Unit/ V-core chip , I hope they can fix it and I’ll give you guys update next week when I hear from them. I give my own review on my channel if they helped me.
Hey, do you guys use a special flux remover solvent or just isopropyl alcohol? Also what temperature are you soldering at?
We solder from anywhere between 600C and 800C depending on the board. We just use alcohol.
Is this happening just on MacBook Pro retina 2012 15 inch or also at the 13 inch one ??
How is he soldering the individual nodes with long strokes? Does the flux make the lead only stick to the nodes or am I missing something?
Kyle Blackshere Yes, the flux causes the lead solder to flow to only the pads on the board.
You´re a Genius Dude Thank You So Much
How to get test drive like you thanks
thanks for sharing your knowledge, awesome video, keep it going.
Thanks for this video
Please can you tell me if that work for a MacBook pro early 2013 ?
Thanks a lot
Yep! It's the same board
Does this fix relevant to an Early 2013 rMBP? The symptoms described appear to be the same. If this is true, I could try to follow this video's steps to fix my vCore chip as well.
The Poor Investor Yes, it is a similar problem this those machines as well.
Is this the same as the late retina 2013?
Sir please tell me what have you applied to it? Flux??? is that what you called it? I've been left my macbook pro for years since 2015 🥺😫
im from Mongolia i should show these video to engineers who fix computers... and tell them what have you applied to it.. thanks a lot
Hi, how are you? I'm from Argentina. Is it the same fix form Nvidia GeForce GPU panic en an Early 2013 MBP? When the MBP changes automatically to this video chip working with Photoshop o Premiere for example, suddenly turno off screen and crashes. Or shoud I do this Job straight to Nvidia Chipset? Thanks Very much :)
Hello from Brazil. I have a very similar problem with my notebook. I followed exactly your directions for resoldering U8900, but continue the issue. I will try to describe my problem, when I turn on, my computer chimes but in black screen, after few seconds my keyboard ligth appears, looks death until I close the lid. After few minutes when reopen the lid everithing is working well. A curious thing is if I turn off my notebook then put it in the freezer, my computer will start normally. I imagine this is a soldering issue. Any idea?
Julio Baffa Hello! It could be the GPU chip itself is going bad, but I can’t be sure unless I was able to see it myself and diagnose it.
Hi i am having this same problem. I dont have any of the tools or know how to use them.which of them are essential for this job and how much all together if i were to buy?
Mahdi The tools are quite expensive, it would be cheaper for you to send it in to a repair center.
Which program you use at 7:26 min with the 5 circles. You said Testeroid or something....???
Micromat TechTool Pro
Hi, great help posting this video, thanks for that.
I did everything as in your video and I got the screen back but I'm stuck with another problem. Once the apple logo appears with the progress bar, it goes halfway and then the screen "Your computer restarted because of a problem" and the loop continues. I'm unable to boot into recovery mode, the screen gets stuck halfway and after a while screen turns black.
Help is appreciated.
Muhammad Umair Anwar Try to double check your solder joints on the Vcore and the surrounding components. It sounds like something is not right in that area.
I did everything as in your video, but there is another problem. On the apple is loaded up to half and after a while it turns off.
Hi, I also did the same as told in video and now I'm there where you were. I'm having the same problem. Did you find any solution? I'll be grateful for the help......!
Can this process fix Macbook Pro A1706 too
Hi! Thank you for the video. What temperature should be used?
Vasco Patrício Glad you enjoyed the video! Each hot air station is different and each person uses them differently. So we don’t share the temps as that is a thing that you really have to experiment with yourself. Just start low and slowly move the temps up.
@@PowerbookMedic thank you. Im quite unexperienced, but will try the fix anyway. The computer is already useless as it is now.
@dta 20502 Every hot air station is different and there are also environmental differences between where people are, so temperature settings will change. It is better off to start low and slowly move up rather than starting hot and damaging components.
you just scraped the soldering points? or did you apply new solder?
Zizzk I applied new solder.
you are a genius!! Thank you so much!!!
Can someone confirm if this would work for Early-2013 A1398 i7 before proceeding ? It randomly has issues with the nvidia GPU.
Is this possibly the issue I'm having if my MBP has verticle pink bars appearing across the screen before ultimately turning into a solid while screen? Nothing appears at all once it goes white (not even the Apple logo on start up). Great video! Thank you!
Yes, it is very possible. If its not the GPU Vcore, then it is the GPU chip itself that has gone bad.
@@PowerbookMedic Thanks very much! I fooled around with it some more yesterday and am actually able to get a clear image using an external monitor plugged into the HDMI port. I have the display setting to "mirror" and while the external monitor looks fine, the laptop display is not legible (pink bars flickering/glitching back and for to white screen with an occasional ghost image (for a second or so) of what is on the external display. Does this mean my display is bad if the image is clear on the external display? Would the GPU need to be working properly in order for the image work at all (even on external display)? I'm wondering if there is a way to diagnose what the actual problem is. Thanks again!
@@johnberry1245 Yeah, the GPU would need to be working in order for the external monitor to be showing a clean image. It does sound like the display itself is bad now.

@@PowerbookMedic Thanks very much for your response. That's what I thought but didn't know if it might be something else. I appreciate your help!
I from chile i need to repair my machine. is possible?
Yes, we do offer international repairs. We do charge an international surcharge for international repairs however due to brokerage and import fees.
@ComoPerro Encontraste alguien en Chile que te ayudara con este problema??? Tengo el mismo problema :/
so do i just ask to get this done from any computer mechanic ? and how can you tell if the reason for my computer restarting randomly when i play csgo which runs my computer really hard. im guessing this is a good way to prevent this problem from getting as worse as that one. what causes the cracking ?
No, most computer repair companies do not do component level repair. You would need to ask if they did component level repair, and even then you need to find a company that is highly experienced in these type of repairs as you can cause a lot of damage if you don't know what you're going. If you can't find anyone locally, we do have a send-in service at this link: www.powerbookmedic.com/xcart1/pages.php?pageid=67
@@PowerbookMedic ok thank you very much
i have a situation like that but mine i see fan spins normaly,charge but caps lock light wont power and display is complet black.I know is on becuse the fans starts when i hit power button...any ideas?? thanks!
When that happens the CPU is not posting. So there is either a fault with the CPU itself or a power line for the CPU is damaged. It would require some diagnosing and measuring.
That may be a thermal conductor (thermal pad).
What if the chip has epoxy around the edges? Not sure how to remove the epoxy to get to the solder without damaging something
Br P You can apply a small amount of heat, and then you should be able to peel off the edge bonding.
Loving this channel
what program do you use to view the schismatics of the board
Free version of Open Board View schematics and boardviews are available on badcaps forum just search by board number + boardview openboardview.org/
sorry, that GPU is the Nvidia one, right? I have the same computer and the Discrete card is almost dead.
My 2012 macbook pro's screen stopped working. There is power but no screen. I took it to a nearby shop and they diagnosed it as a GPU issue and wanted to charge $500-$600 but said issue would happen again. The guy blamed the OS installed. I have family pictures on hard drive I want to recover...
You likely just need a board repair. You can find more info our our repair services at : www.powerbookmedic.com/xcart1/pages.php?pageid=67 . As for the data you want to recover, you could just take the drive out of the machine and put it into an external enclosure without having this unit fixed. That would be the easiest option if all you care about is the data.
What kind of flux do y’all use?
We vary in what we use. For this particular repair we used Amtech NC-559-V2-TF flux.
@@PowerbookMedic Is there a specefic name or size for the soldering iron used? Tks!
@@Mowlson We use a Hakko FX-951. We use multiple tips for it depending on what the job is. We mainly use beveled tips with different sizes.
@@PowerbookMedic TKS 👍
Hi ! Very interesting video :)
My Retina Macbook Pro 15'' (mid-2012), is getting black screen on boot. Sometimes I can boot on safe mode, sometime not.
After lots of digging on line, I figured out that it could be my discrete graphic card (Nvidia) that can be faulty.
I forced Mac OS X to use only the integrated graphic card by running an command line that modifies NVRAM (that command can be cancelled using Apple NVRAM reset shortcut) :
sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00
I can now boot but some features disappaered (like changing the luminosity of the screen, using an external monitor, ...).
My question is the following : is that the same problem that the one described in this video ?
Thanks a lot
Yes, most likely it will be the GPU Vcore chip. We've had many of these with the black screen symptom that just needed the VCore chip to be re-soldered correctly. That should fix the problem right up.
Thank you for your answer :)
Do I need a specific flux for this ? I don't know yet if I will re-solder it, but you never know :)
Thank you.
There are many that would work, but we use NC-559-V2-TF.
i have 820-3330-b mid 2012 this laptop not working i changed mosfet (q8930/IRF6802SDTRPBF). gt650m begin os is ok if i running geekbench 3d test gpu reset to login screen....// if i runnig ASD os test triangle error... i measured voltage if begin tı test voltage reset. gpu vcore (ISL62882C) is bad? //Thank you //
There is no way of knowing for sure if one part is bad or another with the information that was provided. You will need to narrow down whether the GPU VCORE is bad or whether the Voltage In or the Enable lines are the issue. Or possibly if the the GPU itself is bad.
Thank you.

How much did you charge for this service?
You can find more information on our logic board repair service at www.powerbookmedic.com/xcart1/pages.php?pageid=67
Thanks :)
How would you charge for this repair?
Jerry Riggan It is $249.95 if you send in the logic board only and $344.95 if you send in the complete machine.
Does this work for the 2011 MacBook Pro craped out GPU?
GeckoCkCkCk No, it doesn’t work for the 2011 MacBook Pro. The GPU chips on those are what fails.
@@PowerbookMedic Thanks! Think I'm going to have to try one of dosdude1's re-wiring or flashing solutions.
GeckoCkCkCk Yeah, you can run off of the integrated intel graphics card and bypass the AMD GPU. It won’t be as fast but it will not fail.

U’r the man!👍
Ok perfect.
Apple really are a joke when they try this dodgy "repair" can't they use a soldering iron ? ? Thanks for the video, I have one that needs this doing to it.
a rubber... what a shame on apple
