- Hi, in this video I attempt to fix a 2018 Apple MacBook Pro 15" i7 2.6GHz 16GB. Model Number A1990 EMC3215 and board 820-01041.
It has no signs of water damage but yet it has no power at all. Apple wanted £607 to fix it. It has already had the keyboard and top case replaced in June 2021. Will it be an easy fix or will it never work again...Let's find out.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince. - Jak na to + styl

Thank for watching 👍
Vince use gas for lighters to find short - you froze board with liquid gas, then you can spot short in seconds. Check out my comment.
Couldn't save me Vince it was still on top 😟
Save yourself 57 minutes he failed to fix it
Have you tried using a thermal camera instead of IPA to see what gets warm
@@oeinsmyth6868 You’ve missed the point of the video 🤔
you should never get down on yourself for not being able to fix these...even Apple doesn't fix them, they just replace the board. They are so complicated they are disposable... You tried and you learned a lot and that in itself is a win in my book. New knowledge will always be a win.
Man, from 45:10 trough to the end of the video is where i can truly see the amount of dedication you put into every repair you upload, i would've give up after the first voltage injection. Truly amazing work!
Vince always check the 19 v power rail ,check the mosfets at the beginning where you put in the power. If all okay then check the 5v power rail, if okay then check if the bios chip has 3v. I highly recommend a heat camera. Good luck
A technique I've used to see what is warming up is to give the board a good dosing of freezer spray so that it gets frosted up. You can then easily see what is warming up when you apply power and see what defrosts soonest. The other tool I've used is the Polar Toneohm. This is a milliohmeter and is very good at tracing shorts. As the name suggests, it puts out a variable frequency tone, so you can quickly probe lots of points and trace the highest pitch point which would be the lowest resistance.
@My Mate VINCE The reason nothing is heating up on the board is that it's a very low resistance short. The better the short (lower resistance) the less it will heat up. Dissipated power = I² * R, so the closer resistance (R) goes to 0 the less power is dissipated, even if current (I) is high. (A 0 ohm superconductor would not heat up at all, at any current). You'd need a thermal camera to see something that's heating up only a little and sometimes the short is so low resistance it won't heat up at all...
The reason your crocodile clip heats up is because it's making a poor connection. The slightest bit of poor connection will result in a higher resistance in the clip connection then the short itself. For such tests it's best to solder all connections to ensure proper connections.
even when you don't fix things your vids are still very entertaining
Hard luck Vince, can't win them all. Definitely putting you forward for a medal for Patience, Tenacity and Attention to Detail. Keep up the good work. Mick 👍👏🍻
Thanks for this! Its great that you showed the instance when things dont end up all hunky dory. Appreciate the effort and patience you put in. All the best for the next one!
Vince I can almost feel the hours you put into this Mac! Regarding the flir cam, you can buy an used Cat S60 or S61 for cheap and they come with flir cameras. I use the S61 myself and works perfectly
maybe he could find a broken one and do a trying to fix on it
fuaaa que haces aca veo tu canal
@@lup6483 jaja mymatevince me inspiró a empezar el canal. Me encantan los videos. Saludos!
@@ArreglandoCosas saludos!!
I already sugest that couple videos ago, I got CAT S60 and boy, for the price this is awesome tool. Also broken units of CAT phone is quite rare, they are solid af.
Your tenacity is admirable Vince , wish I was able to hang in there like you do
Oh mate - you tried so hard, and learnt stuff - it's not REALLY a failure! I loved it!
Nice one Kip, thank you 👍👍👍
I love each and every video Vince puts out success or failure you got something out of it at least.
From reading some comments and doing some research of my own, I think it is possible that with the failure of the power management chip, the SSD may have also died. I wonder if it is possible to find replacement ssd chips and replace those?
Great attempt Vince, I really appreciate the attempt!!
As always your amazing for the total dedication. Love your videos.
Paul Daniels "You'll like it" "Not a lot" 😂
Nice try Vince, can't win them all
Wow, I don't think I'll be buying a faulty MacBook any time soon! Seriously complicated stuff. I'll just stick to Dear Diary's and Dingbots! 😂
😂😂😂 I'm with you Steve. I've just finished looking at some bathroom scales...I feel good about myself again🤣
And some Botched nec consoles
@@Mymatevince I love the body positivity 😉😆
Vince to find a short without thermal camera there is a better way - just use gas for lighters. You grab plastic end and spray the whole board with liquid gas. It will froze everything so you can spot short in seconds. From my experience this liquid gas for lighters in not conductive, just leave some residue, easy to clean with IPA. Funny story how I came up with that idea - when I rent a flat, landlord close gas stove thermostat controller behind steel box with lock. About 16°C inside room :( But there was a vent hole in that box, so I was injecting ligher gas inside it to cheat thermal sensor on PCB. Gas stove kick in immediately after injection, heating like there is no tommorow :)
Can't you just do this with IPA though ...
@@unitedfools3493 you could, but it's inefficient. IPA is transparent, hard to spot. Lighter gas leave white frost on components, so you could cover whole board with it, then watch for unfreeze spot
there is also a thing called freeze spray for electronics, that is less flammable.
@@csgultekin yeah, you're right - little fire hazard. This is full "ghetto" option, freezing spray is like a standard option, thermal camera is pro option.
Accidental touching of ground with the positive lead, with lighter gas, can lead to more to fix, if not become impossible to do so.
Mon Vince! We have faith!
Keep up the good work fella and stay safe.
I really enjoyed watching this. I used to fix computers but never tried component level repair. I think my brain is too old and damaged now to begin but I do enjoy watching others. And its not just fixing a device, I enjoy the watching the method you or others use to isolate a fault.
Great video! Always enjoy watching your videos! I’m not an expert at all, but I was wondering.. If the SSD is the fault, would desoldering the SSD not give you a picture on the screen? It would prove the fault and you might be able to run macOS from an external harddrive.
Look for cracks in the tantalum capacitors, a hard short is often due to a blown tantalum.
Even trying should be applauded Vince. Well done.
Love these videos, Vince :) Keep it up!
Hi Vince, its the power management chip, the american dude has made a full video about it, because he couldn't source it from anywhere. Its custom made from Renissance chip manufacturer.
Are you there mate?
Great video, great entertainment, I will continue watching your videos 👍
Love your videos Vince, you're a top bloke.
U9500 is shorted sending 3.3V to l9520 , L9521, I would replace U9500 and reball U7800, U9500 has internal mosfets , Reballing that chip would not be an easy job, great video, The only worry is if the ssd survived 👍👍👍
Thanks AR, I knew you would have the answers. So...I looked on eBay at a similar 820-01041 board and noticed that it didn't have the U9500 or the SSD that it fed. So I thought on my one it might work without the U9500 and use the other SSD's. I removed the U9500 and 5V jumped to 20V after a few seconds and then started to climb on the Amps until it was around 1.5V at 20v. Nothing came on the screen, and then the U7800 got hot and it went back to 0.02A 😥. Now it is behaving the same as before but strangely some USB-C ports give 5V and some 20V!!!!! I will wait until a new U7800 arrives and try again. Do you think it could work without that U9500 and the SSD it feeds?
Cheers for the help as always 👍👍😎
@@Mymatevince I will have a look at the schematic then get back to you, But i think you would loose the ssd if U9500 is removed
@@AnonymousRepair Cheers AR. I appreciate that. No rush as I am at least another month away from the chips getting delivered. I'm wondering if it would work from the other SSD chips on the board and just have reduced storage👍
@@Mymatevince I am sending you an email
Good attempted vince. I learnt this model of macbook has bad nand that melt the circuit under to make massive short. But this video still useful. Newthing to me .. milli amp short method. thanks.
Great video Vince, better luck next time.
Send it to North ridge fix 😀 great video vince and hope you do fix it in the future.
Love the long videos, love the mac videos to, please don't stop doing macs videos ❤️
It might be expensive, but you should get a infrared camera like a flir or something. They can connect to your phone and you might see abnormalities inside the board or slight variations in temp that you wouldn’t normally detect. 🤔🤔
You certainly can say you had a good go at it Vince!
Thanks Garth 👍👍
You should buy a Flir camera attachment to see any heat spots 👍🏻
Magnificent effort and all credit to you mate ,Apple products can be beasts when they go wrong so don’t be down about it and still a great video 😀😀
fault finding Macbook with my bottom lip 😂😂- great vid as usual Vince!
Might be time to invest in a thermal camera vince . I know I said this about 2 or 3 years ago but it could help you a lot when it comes to finding hot spots on the board you're working on. Only half way through the video hoping for a great outcome :)
What the electronics world needs is a dedicated electronics version of a bridge megger which measures a short in normal sized wiring and you can "zoom" in on the short by interpreting the reading on your megger, the stronger the reading the closer you are until you get almost a full meter indicating your insulation side of the circuit is bang on the short pretty much but means you can with some confidence cut in a new section of wire. I know the telephone engineers used 'em as did the army and navy etc the navy ones could be 500v output because of the long distances between junctions. My one is I believe an ex GPO Everard unit of 120v which came with a 100ft of line for the insulation circuit and a 10ft line so guessing this was likely for homes or flats sort of application thinking on the average manhole to house distance back then in the days before green cabinets.
I'd have thought something would have popped at that amp level. Complete short would also eventually ruin your power supply. I think you should start doing live vids.
Only the brave would take this on without a thermal camera, respect
Hey Vince, it looks like you could use a thermal camera. I have one that is broken and I've been quoted £220 + £30 shipping for repair. I'm not prepared to spend that on it, so I was wondering if you would like it, for a video, and if you can repair it, it might help you on your next macbook/laptop repair. I've had a look and I can't find your P.O. box reference anywhere. I would send it if I could find the details. The camera is a Flir C2, i have opened it up and had a look, and found that the power control IC has a short, or it gets very hot when the battery is connected. I removed a couple of smd capacitors to see if that removed the short to no avail, but I'll pop them back on if you want it. As far as I can tell, the screen and cameras are ok, but obviously I've never got it to power up.
Let me know, cheers.
Dave.
When Vince put his lip on the board, he was kissing it goodbye lol. Love the videos though.
Great video
good job mate.
16:30 You can get heat cameras which can just plug into your phone. That will tell you where the heat is. Anyway keep up the great videos vince!!!!! : )
I've never owned a MacBook, as I'm not an Apple fanboy. But a lot of the time, if owners abuse their devices, then they will not last very long. And £350 for a non working laptop is ridiculous.
However, I own a Dell inspiron 1545, and I bought it new around 2007-2008. It came pre installed with Windows XP Home, 128Gb of storage, and 4Gb of memory, and it still works perfectly.
I had increased the memory to 8Gb, installed an SSD where the DVD RW drive used to live, and had upgraded to Windows 7, and later, Windows 10, which it is still running. It is still running with the Intel Celeron DUAL core CPU, and the original HDD, which is now used only for storing files. Windows is run off of the SSD for faster boot speeds etc. The display, although not as bright as modern displays, still works with no issue with 720p resolution. And I also have the original battery, which still holds a charge after 15 years of use, although it only gives about 30-35 minutes runtime. But apart from a couple of new keyboards over the years, the extra memory, and SSD, everything else is original, and it still looks like a tidy machine, that still works.
I was so impressed with the length of time it lasted, that I bought a brand new Dell inspiron 7570 in 2020. And I use both computers regularly. I would definitely recommend Dell, based on my own experience.
Heh, this just shows how personal experience has no value. I've kept the same iMac since 2011, taking it from 4 to 16 GB of RAM, and from a mechanical HD to a 2TB SSD - I had even upgraded the graphics board for a while just to play a particular game, and all this on a compact "all-in-one" machine. The MB I'm writing from now is of the same vintage and has been similarly upgraded; I might have had to get a new battery, but it could have been on the previous macbook, I'm not sure about this. It's not been abused but it actually fell a few times with no consequences.
In the meantime I've tossed a couple PC notebooks (HP, they're trash) and 4 PCs - one very good HP (a lightning burnt some chips) and three Dells (all stopped working with no apparent reason, I revived the last one but it's crawling at snail speed and well, that's all the PC I need). I've come to the conclusion that Dells are useless wrecks. Definitely a different experience from yours.
I know a number of people who occasionally have problems with their computer (being the local hobbyist fixer), and I don't see one brand/kind being more prone to faults than another. Mac owners get furious at their computers just like PC owners. If anything, PC people are more likely to just buy another relatively cheap computer and start from fresh; Mac people usually spent a lot on their stuff and want to keep it until it rots. But it's probably only true for the ones I know, as the internet seems to tell tales of "apple fanboys" running to the Store every time a new model is out, and "PC wizards" running last year's games on 20 year old machines :D
@@IlBiggo Well I guess it all depends how you treat your devices, as to how durable they are.
I agree about HP laptops though, as I had the unfortunate opportunity to own one once. They are absolute trash.
But Macbooks are just way too over priced for what they are, and what they can do. And I hate being tied in to the Apple eco system, which can stifle productivity and creativity.
You can't win em all, but a valiant attempt never the less ;) Sounds like something went wrong with the reg for the SSD and the SSD is toast =/ I dont like the way they integrate SSDs this way, and similarly on the latest consoles (doesnt the PS5 have an SSD soldered on too?).
I believe the PS5 does Chris! It is a shame considering the time sunk into it but at least I learnt about the mV way of finding a short. Hopefully that will come in handy in the future. As always a big thumbs up for watching/commenting and the support 👍
@@Mymatevince Yeah that mV short finding technique seems brilliant!
even if you could not fix it this time, was nice to watch, cause that is what happen most for all of us we want to fix something , in fact from 50 devices i've tried to fix i think i have been fixing only 5 and the other45 were totally destroyed =D
I think your almost there. SSD's do fail at random. I've bought ssd drives from amazon, set it all up in computer and the computer had an issue, constant reboot. SSD not listed. I enjoyed that video.
You can try using the compass, a short circuit or breaking a line could be throwing off a magnetic field that you could locate with that, that is mostly used in the automotive field though.
Great information Vince....so enjoy your videos 📹 😘 please keep them coming 🙏 😉 and here to help get your videos 📹 😉 out to everyone to enjoy 😉 😀 cheers 🍻 mate 👍 😀
fascinating! Subbed!
Lol lips, I started really laughing. I completely understand what u mean by more sensitive, what made me laugh is how your mind chose to put yours lips on the board. Just picturing it happening and the kids coming in saying "Dad what are you doing" and there you looking like your kissing a apple board. Lol you have really made my day.
Great video
Haven't watched you for 3 year's since the original Xbox one videos and was just sat there thinking what was that guy with the satisfying voice that used to fix stuff and I remember the hi my name is vice so easy not to forget that
You really need a FLIR for instances like this. I brought the cheap thermometer version to check for sludged up radiators at a friends house but it is surprisingly good for electronics. Well I say that but as most of my projects are valve based everything is nice and toasty. For solid state boards I can spot an errant component easily enough.
Maybe Macbuster a more fun term but I'd never attempt fixing them, way beyond me. Watched loads if not all of your videos, all educational and entertaining. I've bought a few laptops from Fleabay going by description and all were bogus, suddenly it stopped working or untested, I checked them and it was always GPU failures.
did you try The apple configurator without the usb tester? and a proper usc cable?
Multimeter, 1.5 V and 9 Amp power are sufficient to locate short on a circuit. A small size needle compass will tell us roughly the direction of current flow.
Another Mac Book another interesting video. Hard devices to work on as I see.
Maybe, a thermal imaging camera might have been helpful. They are quite reasonably priced these days. Do enjoy your videos.👍
Hi Vince check at South Ridge fix in California the guys masterclass and you learn a lot from him I’m not saying you’re bad at all I enjoy watching your videos but this guys on a different level to everyone else and he specialises in Apple he’s got a shop and he can’t keep up with how many bits are coming in lol.
awsome vid
Vince, I love you and I love your videos are so funny sometimes when you do when you have a sound effect on ha ha that makes me laugh, Vince
Can you please tell me what your microscope is you use, many thanks.
If it’s water damaged alcohol and a toothbrush are your friend. Soak the motherboard (only) in white spirits for 10 minutes then take it out and brush all chip contacts and anything metal with a toothbrush. Then sit to dry for a couple of hours before reconnecting. Not all water damage is visible. I used to buy broken MacBooks from eBay all the time and managed to fix every single one of them. This technique worked on 99% of them without removing any chips
Time to get a small FLIR thermal camera? I got the apple iPhone one, it saves so many guesses and is relatively cheap!
Usb C charge controller is a gonner… or a serious short on ppbus G3 hot
around the blue mat creatures like the usb-c power reader show themselves, often connected to a usb-c cable
wOw,, Very Gallant try Captain @!
These are all I use, and now on my 4th MBP - being they are the only ones with Firewire option for external drives.
My older MBP by mistake missed connection to USP battery back up,,
and was unfortunately hit by lightning, waking to explosion from transformer
on the pole in neighbors backyard,, and in pouring rain left both our yards on
fire from the coolant oil from inside.
Apple had a heck of a time getting him repaired, and had to go back again for
a component they forgot to replace.
Noticed you mention it's not a water damaged event,, but maybe it's a severe line voltage spike that took it out, causing the mystery.
Strangely enough - this new MBP not even a week old went under water,
when Son's mother borrowed it to take a bath,, and two seconds later walking in,, splash,, down it went while playing a movie.
I totally got it to recover by the next day,, and still using it at this moment.
One thing not done - sinking deep into Rice,, what a mental case scene that is
for any electronic device. Basically set it next to the Titanic,, and
let the corrosion process begin with live power not able to disconnect.
I can explain fool proof method another time - or read about it on Fixit.
Cheers
still a super interesting video! Revisit would be nice.
Louis Rossmann's channel has many repair videos for apple devices even some of the issues with their products like a 55volt backlight supply next to a data line that goes directly to the SMC co troller
Just a thought that cable you was trying on the MacBook I believe it dose not carry data only power as you can’t run an Egpu from it maybe worth trying a data usb cable like the ones needed for 5k lg screen apple sells
I think it's time for a thermal image camera to find the tiniest heat spots. You should consider to buy one.
For the car radio from airport fester to remove it. I don’t need a pen check up screwdriver. It has to be a long Phillips screwdriver because there’s two screws were holding Mysterio what are quite low down the hidden so you need a very long Phillips screwdriver to do with very very low down the screws screws, you can’t see them on telly versus Crewe at the bottom so you need a long long do you need quite a long Phillips head screwdriver?
PPV3V-G3H SCREAMS IN ROSSMANN 🤣🤣🤣
Lesson learned don't read the comments when you're half way through the video it spoils it but it's ok i'll still watch the rest of the video because i enjoy them like i have for years now.
Could the RTC rail be related to the clock battery or whatever is keeping the laptops time and settings? If you really wanna fix it, you could wait until someone discovers what it could really be, like the early Phat ps3s
Brush or spray your alcohol to locate hot spot by the evaporation rate.
If we have have a multimeter try trace the min/max voltages distribution on mother board to sort out a hot spot.
Incest a fraction of that £600 on a 2D IR scanner otherwise on a 1D IR scanner.
Get yourself a heat sensing camera to find hot components. There are inexpensive China made ones such as the UNI-T UTI260B available from Ali express.
By the way are you based in Watford?
DEAR VINCE START CHECKING SOME CERAMIC CAPACITORS AND YOUR ON THE RIGHT COURSE ..
THANKS BYE
As well slowly start to understand louis rossmann's decent into madness.
In order to limit your tactile efforts, maybe you should use a thermal camera instead...flir sensor...just a thought...✌️
Are you sure the USB ammeter supports the power protocol required for the laptop?
Good stuff buddy, looking forward to watching this
Thanks Phil... MacBook wins again 😥

@@TheCod3r Good luck with it Phil, hopefully you will have more success 👍
@@Mymatevince haha me too, gotta get paid somehow 😅
@My Mate VINCE you need a thermal cam so you can see what components heat up with you inject voltage
What scope is that looks far better than the view I get?
Adamant IT had a Mac in his shop on CZcams, it was one of those capacitors that failed, the inside middle of the six.
Did you not identify the chip that was giving 3.3 out when it should not but had correct IP? Surely leaving that on would fail your external voltage test ?
Which camera u use for your videos?
I've watched hours of your videos and enjoy each one but I must say you need a a thermal camera, I understand it would take a lot of the fun out of what you're doing but I think it would be worth it.
That board reminds me of Dame Edna's glasses ha ha
Vince, these computers regularly have shorted capacitors around the NAND and the regulator can short because of this. Check this area to see if this is the case.
Get a thermal camera, it could save you loads of time. Take that ssd off next , worth a try!
Hey I notice you already make playlists so here's a tip. Put a link to a relevant playlist in the description, above the link, and a short call to action such as "See the next video: ". Now if viewers want to see more they can choose to click the playlist.
I know what a good video is Vince make a video on how to remove a car radio for so first we need to go. Thanks you need a little screwdriver to do the screws holding in the plastic trim and pull out too far because you need to do a heater controls and then when you’ve done that you need to Take the screws out for the radio, but you need to do this news on the little on the little steering wheel Parlin on the bottom of your steering wheel of a bottle of the steering wheel so you need to do five screws holding your number and then you need to unclip this piece of plastic trim plug guides, and you can move to screenshot hold in which case on the driver side of it, you need to disconnect of heat control things and when we got to the radio I need to take out for a little screws in two medium size screws for two little ones at the top and between medium-size ones are on the bottom road for a man try and slide Radio out. When you have a bang. Can we buy you broken it just means that it’s lost grip on the little thing when unplug everything and I’ve moved a Ford Fiesta from a from a Ford FiestaXxxx
