iMac 27" 5k Won't turn on - No Power Motherboard Repair

[@crnlbwlawson]

Big boss, Thank you so much for keeping Alex a fresh supply of boards to work on. Your knowledge of how every device on the planet comes apart is amazing, not to mention the fact you have to keep half a billion tiny screws organized and remember which customers device they go with! You ROCK sir!!!

[@itikyangbeban]

We need people like big boss for assembly

تحياتي لكل من البيغ بوس و كل من يعمل في الخفاء. حقا إنه من الصعب أن تقوم بكل هذا الجهد و تقبل أن تكون من خلف الكاميرا. أرفع لك قبعتي يا أيها الرجل. لا أنسى الآخرين

[@carlosgomez_c137]

I'm happy every time an Apple device is repaired, of course because their repairing polytics. And if you are the technician who does it, makes them to be ashamed because, with your knowledge, you are demonstrating them and everyone that is not necessary to change full boards to repair any of their devices. As always, congratulations.

[@paolomonai9511]

The futher shame for Apple is the lack of parts for unauthorized repair shop and so one must rely on donor board, as Alex does...regards from Italy.

[@carlosgomez_c137]

@@paolomonai9511 there are a lot of spare parts available for repairing, but from IPhone X to now most of them are paired with the motherboard, so you can't use them without losing funcionality. I was referring to the shameful repairing way from Apple, who only offers to their users complete part replacements (or deny repairing, just what happended to LTT) instead of repairing them, and at indecent prices.

[@RolandKoller90]

There’s a reason for that. You don’t think they know it isn’t necessary? Lmao. They would prefer to sell you a new device and then fix it themselves and sell in another mac as refurbished.

[@carlosgomez_c137]

@@RolandKoller90 of course they know everything, but that's not an excuse, is a scoundrel reason.

@@RolandKoller90 Apple knows, but their customers don't.

And the Thermalcamera once again made a great job finding the issue. The Cam should get a reward for the Empmoyee of the Month

[@ena6631]

Alex & Big-Boss what a team. Fantastic repair, well done!

[@JatinVermaIndia]

Appreciate your gesture of hiding the customer's name👍

[@Heartl3ss21]

Is big boss your dad? Well done by the way on his hard work. People who work in the background never get enough praise.

[@TonyBazza33]

That thermal camera has probably paid for itself ten time over. Great tool.

[@MultiIFixIt]

Big Boss "El Jefe" is awesome, what a team, I can see he treat every equipment with delicates hand, good job.

[@virgildeklerk]

What a team, what a find and fix. Amazing that you all build a business like you have now. good team keep it up

[@gregpeterson1529]

Great repair, show Big Boss some love and let us see more of his work. Removing & replacing boards is not as easy as it looks. Enjoy your videos keep up the good work :)

[@SilverbackFirewood]

Would love to see Big Boss doing some videos on how he does his work of disassembly, keeping all the parts organized, then reassembling!

[@jontait1095]

Great job as always. Would be great to see big boss videos doing the disassembly work and rebuilding aswell

[@mezza001]

You guys are elite! Thank you for your tireless effort to help repair our Macs! I recently too had my Imac 2014 motherboard gone kaput and got it fixed in a few days! Help from repair warriors like you guys!!

It is good to see your team working together

[@empithree]

Great fix. Big boss is the man!

[@nottheengineer4957]

I really like your videos, especially the ones on how to deal with certain situations. Repairmen give the best advice, both for your wallet and your life. You should make a playlist with all of those.

[@stefanlechner]

Very nice work big boss. Its nice to watch him while he works. Alex "little helpers" are very good persons. Thank you for that. Thank you for the video. Good work alex.

[@barrybegley5379]

Alex, the Shop's New extension area is looking very clean and neat. It must be a relief to have a little more room too move around in. Always great videos. I invariably learn something in every one of your Videos even after spending a lifetime in the Electronics Game. Thank You for sharing. It is more appreciated than you may realize.

[@carlosgohn8659]

I watch and i learn with your vidéos. Really you and electronic repair are the big boss to repairing laptop. And you help us to check our laptops . well done to you. Sorry for my bad english. i'm french.

[@TomsTechRepair]

Nice find. Spare boards are very handy.

[@censura1210]

Alex & the big boss are just like Penn & Teller. The big boss plays Teller, the introvert who never speaks 😜

[@modfiles]

I therefore conclude that Voltage Injector Tool + Thermal Camera is a MUST HAVE tools for electronic repair

[@alupci]

Perfect team work! Get camera for Big Boss.

[@Mr.Bearded.Mechanic]

Do you know what would be nice? If the thermal camera has a red pointer. This way you would not need a 3rd hand to point out the problematic component. Great video as always!

[@NorthridgeFix]

It does have a laser pointer. I should use it.

[@gamerpaddy]

@@NorthridgeFix but is it pointing at the spot you looking at? it either needs to be on the same axis as the camera or actively tiliting itself depending on distance

[@temyraverdana6421]

Wonderful team!

[@zerocore8472]

as always,proffesional....even you had the glasses on to avoid blown caps.keep on your great job dude

great work as always. you are a great team 💪💪💪💪

[@aoufal-saqlawi8978]

Keep calm and support BigBoss 💪🏻💪🏻💪🏻

[@proptraderdrew]

How do you make sure other components on the front of the board don't get desoldered while you were applying heat from the bottom? I was worried solder will liquify in one of the components on the front of the board and then fall off due to gravity.

[@d3vastat0r89]

These kinds of multilayer PCBs do not conduct heat easily. They tend to soak it up. I tried once with a UE speaker to remove a set of through-hole pins by just applying heat to one side. I ended up giving up. The PCB and lead-free solder make it very difficult.

[@maxop_91]

Great job Alex... it looks soooooo easy with thermal cam... but there is much more than only having thermal cam...

[@venkateshg9665]

Super sir I'm form Bangalore in india I'm you subscriber your working is super I love it sir Tnkas for helping

[@ThriftyToolShed]

Awesome repair with amazing team work! 👍

[@tareqsahtout9035]

الله يعطيكم العافيه والله شغلك مرتب يا اخي

[@TheLastSock]

So you remove the faulty Mosfet and replace it with a donor Mosfet. Is there no way that you can test the donor one to see if there is an equivalent new Mosfet available? The only reason i ask is it might come to a point where you have say 3 customer boards all needing the same mosfet to be replaced and only two donor boards, so one has to be unfixable. Love the channel..

[@artofrepair6334]

Sir make one video on tharmal cammera We love to see 🤓 we love your work

i was amazed - you can desolder by heating the opposite side of the board! Nice job.

[@thegroove2000]

Those thermal cams are brilliant for finding faults.

How do you get motherboard components? I would love to buy some. Don't know much but I'm assuming they all use filters, transistors, and so on right? Where can I buy a bunch of them? 20-100
