[@megusdp]

Cheers dude! I found exactly the same cap blown

[@dodzhtv]

that's not really a logic board but a ouija board in disguise

[@pauldarrigo4395]

Where does he get those toys? How did you get the schematics and such, mate?

[@001snapshot]

NEW SHOP!!!!!....Nice..:)

[@sobreira-martyndesign3317]

Hey! Greetings from Canada. Like your videos. I recently lost my MacBook Pro 15”, Got rest it’s soul. I had a scratch disk error and since then it stopped working. It is possible to save the content from the hard drive? Or is that dead too?

[@MorrisLiveProductions]

i would like to send some board to you

[@goatwoolsocks3406]

A Mohawk on the chin!!🎉🎉

[@sabsab692008]

did exactly as u. unfortunately for me the cpu got really hot. thnks very much anyway.

[@supererik890]

I think that was the most I've learned in just 20 mins my entire life.

[@ManimalDetroit]

Same here

[@IanScottJohnston]

Tantalum capacitors are prone to short circuit faults caused by age and driving them with too much ripple too close to their voltage spec. I would suggest fitting new ones every time. The heat of fitting the 2nd hand replacement just pushes it closer to the end of it's life as well. Nice repair though......

[@MattP79]

Typical Apple though. Non-standard size, capacity and voltage. Can easily get 68uF 16v poly-tantalum from RS - but of course they're a larger package size and won't fit. New ones can only be purchased from less-trustworthy suppliers on AliExpress and eBay.

[@mattdunlop6056]

not if you're running a shop and trying to make money........time is money.......no one can spend 2 hours on a board that a customer is only paying for 1 hour worth of work.

[@Pulsebass]

@@MattP79 Is there a way to find out the capacitors needed without schematics?

[@MattP79]

@@Pulsebass Often, no. If the chip has a datasheet it may provide guidance on the values to use. That's why "donor boards" became popular. No need to worry about the value - just replace with the identical part.

[@Pulsebass]

@@MattP79 wow thanks for the reply dude ,👍👍 so for example I have and Acer laptop with a shorted cap and i have another branded donor laptop with what seems to be the exact same cap physical size & colour etc should it be ok to use ? Thanks again 👍👍

[@richieclarkie]

Quite possibly the most well explained, easily understood repair video I have ever seen! Subscribed!

[@smokecandyz]

Congrats on the new shop, Graham!

[@vlads.]

Do you think you could do a video on your multimeter? I was planning on getting that same Aneng and you going through how to use it for these sort of repairs would be really cool

[@Adamant_IT]

I'll add it to the ideas list, I have been meaning to. I don't feel super qualified to talk about test gear - but all the people who _are_ qualified are all doing super high-end stuff.

[@marklucas8110]

"half a gnome" 😉 Nice to see you have a new shop Graham. Great channel. Learned a lot watching you work 👍

I love these air boards, they look so clean and so easy to work with, too bad theres very few macbooks where I live here in brazil, I'm sick of fixing acer keyboards XD

[@bennaambo2716]

Uh ya acer sucks

[@lucascamino8615]

Great job!! This helped a lot!

[@stephenhr6938]

Thanks again for a great informative and entertaining video. I really look up to you my man

[@JiinCheng]

Thanks. The video is clear and helpful for a beginner.

[@alexandrafreeman8135]

Mr Rossmann would be proud

[@izigswe]

Nah, he want the board to drown in flux.

[@elizabethtorres6069]

I have a similar type of problem with a Acer e1572 which started up before, even with a blinking Amber LED lite and after replacement of Memory RAM and new ac charger. I couldn't reset to factory settings from the main screen. So I decided to disassemble it to reset the CMOS battery. Unfortunately this model doesn't have a CMOS battery. After reassembling it, it will not start up. Thinking it was the Battery Pack, I bought a new one. The LED is blue indicating fully charged, no fan sound nothing. Still it will not turn on? HELP!

[@adrianaturela9165]

I bought a Macm1 2020 on Amazon on July 14, 2024, I opened it and created an Apple ID, it went into recovery activate mode, the 0800 says it is not connected to the Mac. I sent an invoice to prove that it was not stolen, but they did not allow me to restart the Mac, nor did I use it. Immense nonsense, I haven't even paid for it yet. I don't know what to do!

[@benn87]

I really like the way you explain things. Very detailed and informative.

[@howardtaylor229]

VOLTAGE INJECTION TIP: When injecting voltage to a circuit board to identify a short be careful when feeling for the hot spot because it will burn your penis.

[@chrisgr00ver]

Appreciate your videos! I got a MacBook coming my way with the same issue, hoping it’s this easy.

[@benischmit7081]

Hello, I have a 2015 MacBook Air, and it doesn't turn on According to you, I determined by the training video that my fuse had burned out and, possibly, the capacitor Could you please tell me how much such a reporter costs you?

[@vincentmoolla5462]

Hi I'm Vincent. I like to say this video give me hope that I will have my lap top working again. where Can I find someone to fix my lap top in South Africa KZN Durban.

[@djjammindave]

I NEED TO DO THIS TO A 2011 MACBOOK PRO A1286....I THINK I HEAT THE COSMOS INSTEAD OF THE GPU ..... NOW THE MACHINE WON'T START UP. IS DED, BUT CHARCHER CABLE SHOWS GREEN LED.

[@dougler500]

I love when you do Macs because all of my other Mac repair input comes from Louis Rossmann (awesome source, not complaining at all) and it's so nice to hear alternative descriptions, plans of attack and level of detail from another skilled repair outlet. Awesome, awesome, awesome.

[@mattdunlop6056]

I feel that people who recommend a thermal cam think that you can just buy one of those cheap knock on phone ones. Sorry.....its not that simple......maybe for viewing a ice cube.....

[@Ali-AP]

I have the same model and voltages are good, looks in great condition, it just does not power on... did all those "resets" that people do in thousands of videos and nothing, disconnected the battery and reconnected it: nothing. Yesterday I took it apart completely, reassembled and THEN it had power, booted, worked fine, restarted and turned back off and on several times. I went to sleep, woke up and it does not power on again..... just what in the hell is going on with these macs.

[@tnetroP]

Came here expecting Adam and the Ants new IT business. Video did not Stand and Deliver. Left disappointed.

[@byungwoo1003]

Hi, my Macbook Air does not turn on after Water damage. Can you fix it? Can I get some information how to send to you and estimate? Thank you.

[@carldean3848]

How would we go about checking and testing for Pp3v42 if the light did not work on the cable ??

[@Rocquichan]

Thank you for your teaching, You are great, Adamant IT!! Do you run any courses on repair and maintenance ? or have you thought about it? Cheers.

[@mladenmilosavljevic4788]

My Macbook can't turn on...just light on right side of unibody

[@zoltankecse991]

Hi. Can you tell me what's the type of camera what you are using above the board? Thx.

[@raulmorel1872]

hi, i recommend you always remove the headsink from the cpu , you never know its that its damaged. good video sr

[@PaulDarrigo-q6j]

Can you fix an iMax Pro 2017 logic board?

[@universityrepairFL]

Pretty common 😂 just watch another video about the same thing but i like yours

[@mohammadrazmi9467]

I just do not understand where and when to inject 1V and when to inject 5V or more i.e. could you explain to me plz :)

can you repair mine also i have 2015 mac air and also one more no backlight let me know thanks!

[@jblack8149]

So there’s more to being a tech or is this engineering g? Do every tech need to know this or is this just something a tech can refer to a board repairer?

[@christopherfarrell-artist3557]

This is the work of a genius.

[@TCRSCircuit]

Nice! Gotta love these easy ones.

[@aceace5457]

i was into board repair and it is so good to watch you do these repairs cant wait for the next one oh by the way when you checked that board you did not have anything but your hands that we could see is there a true way of finding out exactly .

Hey man new to the channel great vid however have a macbook air no short circuit on either rail no power wathsoever any help plz

[@universityrepairFL]

Yep thats the one that goes bad ! Its connected to the ppbusg3h you hotwired

Do NOT buy Mac. This is the simple and only solution.

you cant guess to properly fix pcb you must be a real tech not a guesser

scissors, clipper, lawnmover, anything... haircut, now! :D

[@Adamant_IT]

I know, I know! I'm beginning to consider buying some clippers.

[@lostinspace2009]

Just curious , why Adamant IT ??

[@rick5078]

while you save up for a thermal camera, a simple can of "freezing" spray will do just fine to find the short.

When are you going to invest in a decent microscope? Visual inspections are OK but you can miss quite a lot without a good microscope and its a worthwhile investment that will pay istels back rather quickly. You'll be able to fault find soooo much quicker..... Oh and "GET A THERMAL CAMERA" lol....

[@kaiserkhalil1]

Clear sound easy to understand (specially for non english ppl)....can i ask which camera and mic you are using for recording? Can you explain how to test mosfets in motherboards..they are really confusing 😔😔😔

[@SuperStarReview]

I am working on a a1466 where the macbook air will turn on once I unplug and re-plug the battery cable on the logic board. The charger works correctly going from orange to green. When I had the macbook air powered up, I could restart it several times without a problem. However, if I shut it down then it would not turn back on. It definitely had a minor spill (chocolate milk) that has been thoroughly cleaned out and the logic board looks prefect. The main power board (where the charger plugs into) had some rainbowing on sveral terminals which I scraped to clean it up a bit. I am almost done putting it back together and was hoping for any advice or guidance? Do you know what could be wrong? Cheers.

[@desmondpkandemiri1971]

Fixed one like that one a few minutes ago. It had a short on a RAM capacitor on the far left when the board is upsidedown. Actually I didn't inject voltage, the capacitor had brunt the plastic under the keyboard, and I just pulled it out. Didn't replace it though ;)

[@RobertLongM]

How can you check if the actual Keyboard Power Button is working? Is there a way to bypass the keybaord and power up?

[@keith3162]

That was most excellent!

[@sradrvr]

my macbook pro 13" late 2013 took a big gulp of hot tea and shut itself off instantly, i opened it up and dried off the logic board as much as possible, but it took a week to get a screwdriver set to get the logic board out and flipped around. i opened it last night to see two small spots of corrosion, cleaned them up with 99% alcohol and still nothing works. power supply shows a light to indicate the batteries still take power. i thought maybe the keyboard was dead or the ribbon cable got damaged, so i tried jumping it with the direct power supply/disconnected battery, as well as with the power pins on the board, nothing works. the guy near me wants me to pay nearly the same amount as a brand new macbook pro to look at it and MAYBE fix it, PLUS whatever parts it needs. this made me realize there's a lot more to working with logic boards than just the base parts, could be literally anything or everything that needs fixing.

[@abrasado1]

What is the name of your power source sir?.. where can i buy it?... i can't see anything like yours which you can inject the current at your own will.... which is not a constant current?...and my power source will turn off if he can detect short circuit...hoping of your response sir.. thank you :)

[@Prinzessin_Luna]

Did you replace the fuse too or only the defective capacitor? I think my Air has the same problem.

[@pwfcpwfc]

just curiosity , for the schematic , is there any legal consequence for using and showing it , there is wording on the schematic said that it is proprietary property, a lot of KZbinr using it on their channel , seem nobody care. I want to show it on my future channel also. Thanks

[@allskoolguru]

just wondering, how much do you charge for fixing that macbook air? like what would be the cost?

[@francoisguyot9770]

That's a nice troubleshooting step by step procedure you conducted out loud there. It's very clear and helpful. I would have used the spray method to find overheating component in the absence of IR cam though. Denature alcohol dry fast and clean but dries super fast in the slight presence of heat.

[@felixajorg]

Great Video. I am dealing with a dead Mac Pro myself. On my way to the hardware store to get the right tools. Thanks buddy!

[@thiscouldntblowmore]

New shop? The old one seemed pretty cozy. How is the new one then? Bigger? Cheaper? or what? Maybe do a shop tour once settled in?

[@concinnity1240]

@3:05 “Let’s see if we have a short to ground.... *DMM reads half an ohm* Ah.” 😂

[@ianide2480]

You are not wrong that if a capacitor is measuring a tad over, it's no big deal. I believe it is important to stress the point, that it's ok if it's over as long as it is inside of the given tolerance. This is important because a leaking capacitor will show "over" capacity, which is to say, it's going to fail soon. Best to replace with a new one IMO. Take this for what it is worth, or with a grain of salt.

[@petarkirilov1097]

you are a wizard man…

[@coreybabb3591]

You can use you phone for a thermal cam until you get one. I’ve been using my phone until I can get one myself.

[@2009numan]

you replaced the faulty capacitor, but what actually caused it to fail?

[@Adamant_IT]

They tend to fail at random. The laptop also got sat on, so it might've just been the point where it got bent.

[@optimizelogicrepair2784]

They hate heat, and fail from heat stress.
