Someone who sees a blown fuse and searches for WHY before replacing the fuse? Madness.
Yes troubleshooting is a lost art. I have seen people put in foil to replace fuses and say its ok since it works.
He'll also wait for the fuse to blow!
How else could you find the fault?
It's something which is discovered right at the beginning of the learning curve. Fuses are to protect everything between them and their supply voltage. If you don't look downstream and fix the fault, all you will do is blow another fuse. Or, worse, you'll blow more components downstream as well as the replacement fuse.
I'm a bit surprised that black sheep didn't check that the short to earth had gone before he powered up. I guess he has seen this fault many times and knows that it's a single component fault.
I've seen some "TH-cam mechanics" use a thin speaker coil wire to jumper the fuze. lol While it may work it's not the safest or most elegant thing t do.
Also, I was wondering how come Louis never (or rarely) does any iPhone/Samsung/LG board repairs, which is usually the bulk of work most repair shop do?! Hmmmm
Moment of silence for all people uploading schematics, and bios files for us technicians.
Many Bothans died to bring us this information.
Whoever you are; you da mvp
And Epstein didnt kill himself
wish they would send the schematic and board view fairy for Mac Mini's
lol, you are transcendent
The first thing I think of when I see Louis Rossmann is *PPBUS underscore G3 Haa* I find my self repeating this phrase for no absolutely no reason. 🤷🏼♂️
he says PP a lot. I wonder how long a video of just pieces of videos of him saying PP would be if it was all put together
@@prjndigo It would be so long that you would definitely need to take a PP break.
I have absolutely no idea what Louis is talking about, but listening to him calms me. I said it before, Louis is the Bob Ross of board repair. 😊 I'm changing my band's name to PPBus and the Fluxxers ..
*hot* not haa
Those numbers just blow by my brain as meaningless mumbo-jumbo. lol Now if you said the power rail on a MacBook xxx model, well that's completely different. It's usually autistic people who remember such small details.
most common failure: buying an apple product
Finally, someone who gets it. ;D
hahahahhahahhahahahhahahhaha i Died with this one
So tired of computer elitism. You’re just a child. All computers are pretty much the same, except that Macs run OSX, or Linux, or windows. You can run anything on it. That’s one reason why it’s a better choice than a PC, and it’s the right choice for a lot of people. Get over it.
@@ophello I think it's pretty ironic that you are accusing him of being elitist and that you are being elitist by saying that Macs are better than anything else...
Ooooh, so edgy! You must be proud of coming up with that one. Hurr durr.
imagine:
Refusing to eat the bugs
Refusing to live in a pod
Accepting a $1,500 Apple repair bill.
Based and blackpilled.
Who else has a broken MacBook but doesn’t have a single clue of what he’s saying
I got the bit where he was silent
Looks like you should send it to him then so he can worry about fixing it.
yup
Having the worst day rn as my Macbook Air shut down this morning and wont turn on and I have a deadline this week with everything on my mac. After watching tons of vids today trying to fix my mac, I stumbled upon this vid even though I don’t have the tools or skills. Suchhh an entertaining vid you are so humble and funny! Made my day a bit.
I love that you are so real even when you tell people that they can buy from other companies, you deserve a sub
I write software and don't fix hardware but I like Louis repair videos because I firmly believe that every problem has a root cause and you can work logically to find it and fix it. This and my job are the only few things in the world that still make sense.
"Yeah, get wrecked adblock" - That had me chuckling.
Not me, that ad actually got me to download SponsorBlock. I like Louis but I HATE ads.
ikr ! Like how did that happen ?!
I have sponserblock lol
You will never see a tantalum capacitor in any piece of automotive electronics because of the ways in which they fail. Apple seems to like them quite a bit for some reason.
They have pros and cons like anything.
@@3nigma.3nc Pros: They break stuff, cons(pros for Apple): Makes consumer buy new items which break.
To repair electronic boards, one needs to understand basic electronic hardware, i.e., capacitors, semiconductor chip and the knowledge how to use and read the parameters shown by these equipments. Also, the knowledge of reading and interpreting schematic diagrams of the circuits boards is also necessary, Apart from that one needs to have an investigative drive to explore the possible issues that could have caused the problems int he board. This will be possible if you have a good amount of experience in doing these activities by trial and error.
Among many other things you don't even mention, you'll need a good brain, and at LEAST 1000 hours experience in one corner of the market, say macbooks or TV's, to have any chance of making a living at it. Trial and error will simply take too long to be of any use in a commercial setting.
Also, sharp eyes and a good sense of smell, often those 2 things will make everything else irrelevant by bringing you immediately to the failed component.
tasmedic what about good sense of smell?
You make our days save our money. Show people the real path.
Thank you mr rossman.
Love from Japan.
You said the fuses are the most resilient components in MacBooks... Are you sure that's not a counterfeit? :)
On a serious note your videos are very informative and nice to watch! Thank you!
I just lost it at the "Get rekt adblock"
It symbolizes perseverance and hope amidst hardship ("' A tree grows in Brooklyn")
Louis, Plug your PPBUS into Apple's PPBUS and shoot 50 volts into their "CPU"
unfortunately, that cpu is made from superconducting transparent aluminium. 50 volts wont hurt it...
a bunch of bullshit (should be obvious but still)...
@@seven9766 There's something called "figuratively speaking"
An apple a day keeps the wallet away...
Serious question: Why even have a fuse on the logic board if Apple refuses to repair a board and will only replace a board for $500 plus?
Even if you have a gurantee they wont replace it?
Many bothan spies died to bring you them macbook schematics
Damn Hackermaniac is a real dude I got some recommendations about him a d decided to chat him up on Instagram with my issue. At first, I thought he wouldn't be able to work it out but to my greatest surprise. He got my MacBook pro repaired . Now I'm so happy that I'm able to access my informations on my MacBook.
Another damn shorted capacitor..... What the hell Apple make to those caps for them to commit suicide by Puuuffffff... lol Another successful repair hehe. Indeed, I DO learn something every time I watch your videos! Thanks for that
man, ure my tech Bob Ross
greetings from germany
That's not a common failure.. That's a usual failure of this MacBook and I had already so many MacBooks with this failure.
I even once found few of these on my local recycling station and all had also the same problem + a lot of private data 😅
Luckily those machines were "Engineered by Crapple in California" ;)
How do you learn about all this as a complete beginner with no experience in engineering?
See ya guys! I'm off to Shenzhen for some INTERSIL ISL9240 Chips! I hope the Huaqiangbei Black Market has some nice people? If I don't make it back...... Just know I died fighting for the right to repair! For the Innovation Economy! For the security of Apple devices! Right?........
It is only Apple who can blow up a moulded aluminium polymer.
imagine a fuse doing its job in Apple product
I'm kinda new to this channel and have only soldered larger items, e.g. headphone wires etc, so I'm a bit miffed. What does he pour over the board before soldering? I guess it might be liquid flux, but I'm a bit short on how it works.
ro4ers in answer to your question there...
1. A keen eye.
2. An attention to detail.
3. A whole lot of love.
4. And as you stated, Liquid flux....see 15:19

I spilled coffee on my new Mac book air 2018 , I had it only one month. I handed in x 2 Nd they could not fix it because they are scammers . Right now when I turn on the computer it flashes like there’s something wrong with the Track Pad, mouse . If you can fix it : my email : caseykcrichards@gmail.com I did take the mother board it myself ,
It's amazing - the fuse actually did what it was supposed to.
Must've been an oversight by Apple Think Different™® department
"The Dark Side of the Fuse", written, produced, directed, filmed and interpreted by Luigi Rossmann as himself.
Yeah, I can see it! Paul and Louis as the uber jedi and apple as the sith lords...
OMG! An Apple fuse that actually blew to protect circuitry instead of frying it?? Don't tell me they're finally learning basic electronics?!!!!!
What’s going on boss, big fan of yalls work over there. I am a new TH-camr that has ran into the same problem just yesterday as I was naming my video to post on my channel. I was wandering how much you guys would charge to diagnose and fix the problem.
But we were taught that Apple products never blew fuses! They're the most durable part. It's the *rest* of the board that's supposed to be used as the fuse.

Hello, nice work and I really love your videos.
I have a 2014 11” MacBook which I have been using since 2014 till date but a month back it ran out battery and it wouldn’t turn on so I tried everything including the disconnecting abs connecting the battery back until I did the smc reset which actually worked and it’s been working fine till 8 days back. The system was fully charged and I decided to shut it down because the airdrop was acting up. Ever since I shut it down it has refused to turn on or charge ( no light on MagSafe), tried different working chargers but it wouldn’t work on my system. Tried the smc reset, disconnecting the battery, touch pad flex and even removing the sscid and replacing back but nothing is happening. I am currently in Nigeria where there is no apple store and am scared to give it to some random repair guy cause they might cause more damage to the system.
Can you pls help give some clues as far what could cause the system to breakdown like this. And what hardwares or chips fault could result go this.
Thanks for your anticipated response
Olivia
My 2015 Air died after less than 3 years of use. The Apple service center would charge eye watering prices for it. A non-apple center just told me it had a "dead board" and I had to buy a new board which would cost almost the same as a new one, and that was the only other repair center in my area that had the chops to repair it. I was so dejected, it's now gathering dust in a corner. FML.
This macbook is defective, the fuse blew.
it's not a macbook, blowing the fuse turned it into a PC
Windhelm Guard 😂
"I have employees to feed"...lol
Wifi/BT module looks like toast, anyway good job
The most common reason why a Mac fails: it's a Mac.
I blame the sheep first then Apple.
im more surprised that the fuse actually blew
Does anyone know how Louis gets rid of that sticky mess that gets left behind by the flux?
I have seen him use a qtip, but what chemical does he use on them?
Isopropyl alcohol. Evaporates quickly.
What temperature do you normally run your reflow gun at for this type of SMD removal?
By now louis must have replaced everything in a macbook
That's weird, a fuse is blown.
How much would something like this cost or do I have to ship it in first?
You got me at "Get Wrecked Ad-Block!" got me good because I use it
Thanks for all your hard work and for sharing all your knowledge !!!!
HELLO OUT THIER...
Is there,
A really good site ?
To sell/Sale some.
Used... & or Broken.
I.E. parts ONLY.
Air's & Pro's.
From 2012 to 2017.
THANK YOU !
VERY MUCH FOR
ANY POSSIBLE - LEADS -
Nice moment of silence. As a govt employee I will petition my rep for "Schematic Provider Day" so I can have yet another day off.
Apple 🍎 Monterey just BRICKED my 2018 Mac Book Pro - know anyone in Delaware or where the “brick” can mail in - Apple Support assured me it was “safe” unfortunately I trusted them and didn’t check the Internet 🤬
I am very happy to see your progress finding a new space, and also very happy to see your work in the right to repair movement, but I really love the board repair videos. Thanks for another great repair video! Congrats on your first million subs! O7
do you have a theory why capacitors fail after liquid?
my first guess is like two caps connect together by liquid and over voltage a third cap.
let me seek for help please - I have a Super Weird behavior air 2014
- it does not start with pwr btn press, I need to press it like 10 or 20 times and afterwards, it will turn on.
- When it is turned off (by holding power button) the fan spins every about 15 seconds, but just spin and stop * when it is turned off*
- when it's turned on, it works flawlesly, battery holds 6-7 hours.
- I am not able to update to APFS OSX - no problem to install any op to High Sierra. that one and above shotdowns the mac off - my gues during firmware update, when black screen with apple and minutes counter is shown, shutdowns at the same moment everytime
Thank you for help ! I did everything I've found over internets, trust me Im actual engineer :D but this is first mac I am working with
help pls
Hey Louis, I just follow your method to check my 2011 MacBook Air A1369 and found out one of the fuse and a (A1 V7e) capacitor was burned, do you sell these two parts?
I have a macbook air, my screen flickers. I sent a tech on ebay the information and is what he wrote me back. {This is a bad video chip on the logic board. We can reflow and it may work fine after that. $100} is this lots of work to fix? and reflowing it what does that mean? thanks.
amazing work! im just learning to rapair this boards.. ands this fantastic information!! Thanks so much!!
Hey I replaced motherboard on my air and cannot instal Catalina, should I install mojave and then catalina? I suspect old firmware on new logic board since I had to change date from 2015 to 2021 using terminal, not sure how to upgrade firmware... or is it the real reason ;p
I live in Indonesia, do you know anyone with this equipment and skill set in Indonesia who could do this for me? Apple want Us2000!!!!!!!
a2179 won't pass mac logo... progress meter fills up then hangs... google isn't proving much use, nor the apple care line. 2 reps said they couldn't pinpoint issue and suggested apple store 200km away so that's where i'm going looks like. any ideas?
Mine is macbook late 2011,logic board corosive, battery shows repalce now, screen look bad, should i buy new or i can fix it specially the logic board...
Wish you would zoom in more when you are testing components.
Hi Louis what’s a safe temperature to remove board components without damaging the board or nearby components? 🇹🇹
You fixed it wrong. Where's the hammer? Where's the garbage disposal unit? A good Apple product is a product that's not Apple.
When this video first came out, I'd take a shot every time he said PPBUS. The hospital said I'd never make it. Just got out.
:D
After changing hard drive Mac Mini USB drive stop working. what could be the issues? & how can I solve it, please?
Can I get a tech support on call to guide my engineer my 2017 macbook pro a 1707 died. And I have no idea what to do I live in INDIA apple does not do baord repair in INDIA could somebody help me please I need my laptop be alive back
How much should a repair like this typically cost? I have a guy quoting me nearly $600...
How you did that? Iam heating since 1h, cant get ic cap up, now 1000$ board is really dead, all nearby caps are gone
Sir i just want to asked i have a 2012 macbook air A1466 i cant figure out whats wrong.. it turns on but super slow to the point it is unusable
Water spilled on my macbook and when I sent it to repair it, I was told that the battery has a problem and I wont be able to use it without it being plugged in. Now it wont fully boot up and now I'm hearing that its a logic board problem. Can it be fixed or am I going to need to purchase another laptop.
How much is the fuse for a 2011 MacBook Air and a Capacitor "A1 V7"?
Hey Louis! How much did this repair cost them?
Great respect for your work Louis. Even in Holland you are an inspiration for a lot of people. Thanks man!
And.
Man, this is like Bob Ross... love to watch this and Louis his voice makes my brain very satisfied. AND we learn something.
Wait, the motherboard works even if there are not the other parts of the MacBook ? So I can create my own Mac with just the motherboard…
I just celebrated my macbook's 5th birthday yesterday. But it's macbook pro mid 2014, not the shit they sell nowadays.
You've got one the last, best MacBook Pros (I always think of Mad Max eulogising the last of the V8 Interceptors :)
1:55 And here we see Louis offering a moment of silent prayer to the Patron Saint of Board Repair.... Paul Daniels.
Always educative, watching from Nairobi ,Kenya.
The MacBook is faulty by factory, is gonna die, its inevitable
never any help....I do not want to spend 70 dollars to get a 2013 ssd 12 16 pin card
@louis rossmann . Sir any apple macbook repair course teaching institute in your country
Mine is booting on and then few seconds starts going on and off what could be problem or could it be ssd?
Hello brother you can reach me how to use software intel easy clean Me?
Hi i have a macbook air which is not rueing on no matter wt i have to seevice centre they say that the power managment cheap is dead n dat its not available and need to replace the entire mother board can you tell me if there is a way i cn get it working
every time I read "fix macbooks" I think "buy an acer, its cheaper" I'm not wrong.
Except Acer cripple some CPU features in their laptops. I had to actually mod my bios to get virtualization enabled so I could run a virtual machine on my Acer laptop, because the option was even removed from bios.
Apart from that it's a decent laptop.
@@ThatStella7922 Virtualization on a single core Atom CPU. Yeah, right.
Pretty sure this 2015 Air
Im looking at has the same issue!
how to turn on a macbok air without charger via a power station like yours?
thanks for supporting right to repair! techs without much soldering skill, (around here there are no solderers or motherboard testers), we only have part-swapping option and swapping out parts is cost prohibitive because of outrageous prices since they are all salvage because of apple's closely guarded part manufacture process, i presume
Any MacBook Air no power I think ram … take the mobo out and throw it in the oven
Where can I purchase F7140 replacements thanks
Louis was a surgeon in a past life.
Can do re-do this video in English please......😆
That moment of silence seems incredibly challenging
How much would a tech charge for this repair???
Wats goin on with the caps shortin out quite a bit laty
@imflori dano equally fascinating is why their near indestructible fuses are blowing too ?
thank you for the schematics internet people.
Many bothans died to bring us this information.
I was wondering how come Louis never (or rarely) does any iPhone/Samsung/LG board repairs, which is usually the bulk of work most repair shop do?! Hmmmm
Most?
Well, most shops are into phone repairs. Not saying that MacBook repairs isn't interesting, but maybe sprinkle some phone board repairs in there too, which would certainly attract even more viewers. ;)
Computers are much better to work on than phones
@@universityrepairFL - Well, 90% of my work is phone repairs and data recovery from phones, while making a decent living. I was just wondering why there are almost no phone board repairs shown. But hey, beggars can't be choosers. lol
