MacBook Air Doesn't Turn On - LFC

[@supererik890]

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

[@ManimalDetroit]

Same here

[@richieclarkie]

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

[@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 👍👍

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.

[@RobertLongM]

My head hurts how much you know about these circuits. And how far you go! True Professional.

[@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 .

[@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.

[@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!

[@marklucas8110]

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

[@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!

[@JiinCheng]

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

[@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 ;)

[@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.

[@chrisgr00ver]

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

[@Sesj02]

I've never seen such beautiful hands on a guy before

[@benn87]

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

[@zero0ryn]

A high reading on a capacitor read from a DMM can also mean leakage. Remember DMM's measure capacitance using charge timing. You can increase charge timing by adding leakage.

[@Adamant_IT]

Yea fair point. In this case we were like, 1 or 2uF out, I'm sure it's fine. But that deffo sounds like something to look out for. I'll have to do some comparisons with my component tester to see if there's an easy way to test for this without an expensive LCR meter.

[@itaamelia6715]

compare to other channel, your explanation is crystal clear

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

[@benNdaKen]

Uh ya acer sucks

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?

[@carldean3848]

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

[@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.

[@tejp5101]

Thank you for this very informative video. I liked your explanatory style.

[@kaiserkhalil1]

I have a problem in my macbook air 13 it won’t on the power button even if I replace a new battey what should i do? Can you please help me sir?

[@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.

[@raulmorel1872]

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

[@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.

[@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.

[@woodant1981]

This guy isn’t an expert... He’s a god! Good work man keep it up! Any tips on re-soldering an AM4 socket? Got a replacement one for my B550 board and have been practicing on the old one!

[@Adamant_IT]

Not yet. I want to get into socket replacement, but it's a rainy-day project at the moment.

Congrats on the new shop Graham. I do hope we get a Captain Cook at some stage. I was stunned at how small your previous one was because the opening shot of the video made it look a way site bigger than it actually was. I assume that was due to camera lens distortion. I wish you all the best and that everything turns up roses. 👍

[@oscarmarfori613]

Thermal camera Man, that's essential now a days

[@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.

[@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 :)

I have bought a macbook air a1466 emc 2632 2013 model I believe. . The LCD Screen does not light up but there is an angle where I can seem to see the log in password window but very faint.. but plugging to an external display and there is no issue it will work. . Would it be a lcd replacement? if it is do you suggest buying the whole replacement assembly or just the screen?

[@Adamant_IT]

That's a backlight fault. At 4:00 I show basic checks on the backlight. See if the output diode is shorted to ground (_should not_ beep in continuity mode) and then check that the fuse hasn't blown ( _should_ beep in continuity mode). Also do an SMC reset and a PRAM reset, because sometimes it's a software issue and you get lucky. If the backlight is shorted, it's likely a damaged display connector, or the display itself needs to be replaced, or both. If there's no short, but the fuse has blown, just a replacement fuse should fix it.
