Sorin is the greatest teacher for amateur electronics lovers. Each video is a story in itself, it is simple and logical. Thank you for your effort and time, Mr. Sorin
If you watch about 50 Louis Rossman videos, which are only about Apple MacBook, you will learn all the rails, voltages, and likely fault locations. As Sorin does, they both go to liquid damage, while Louis just mass replaces all parts with liquid damage, Sorin does not have an enormous pile of dead Macbooks which Louis buys. A bunch of replacement component boards. Apple started getting sneaky and evil by marrying components on the board so you can't just replace a hard drive or graphics chip forcing evil electronic waste so you have to buy more new stuff. Just completely evil like Putin, murdering innocent people he thinks somehow he owns, the bastid.

"" SIR ""greatest teacher for amateur electronics lovers. from BANGLADESH
Best of the best is back !
Many Macbook repair specialists like Paul Daniels or even Louis Rossmann reball this tiny 1.4 x 0.9 mm BGA load switch before soldering it back on the logic board. Excellent and fast job Sorin. You're the man.
But as u know they will not fix it without schematic and board views. Also im sure they're resoldering that just on camera otherwise its skipped
@@tomicekgrundicek5131 Probably, but on the other hand, they charge for board repair 300 USD+, therefore, perhaps they indeed include full treatment of the board.
A lot of the extra care we give to these boards really have no meaning in quality-wise. Different techs go different ways. Some even solder chips on top of the old solder. It's basically the same. It's always good to go the long way but the point is arguable.
Paul Daniels. The OG magician.
I'm also a fun of the programm show '' Second from the disaster '' this kind of videos give you a lot of things about how people react and what they do in those moments
We have a saying here in the Appalachian mountains, no pain, no gain. Hope your finger is okay. Nice job.
Such satisfaction to be able to fix this. I think i'm going to call this guy the alcohol guy. When he said he had no more alcohol i cracked up. Literally everything i've seen him repair has been by using alcohol. lol
That 'good feeling' never gets old. It's what keeps us going. Thanks...
NO COMMENT!!! It's AMAZING!!!!! Thank you for sharing your experience without editing!!! Good luck! Respect!!! Greetings from Moldova.
you're not too old for this things, but you're AMAZING !!!!!!!! Best Regards from Jakarta Indonesia
Really nice going you found the problem where the company store couldn't, my hat is off to you Mr. Sorin
Master Sorin, please keep this really good work up, do not leave us without a new video. I have learned a lot of tricks, tactics and diagnosing methods from your videos. Even I am not working as computer workshop worker, I love watching your videos. Greetings from Turkey.
You are a nice human being
55:28 we've the Apple logo and it starts loading the windows operating system 😊
Good catch!
Sorin trolls ☺
Thank you for fixing the customers apple laptop.
He will be very proud of you and very happy for having back his working laptop.
You a are true laptop Doctor.
and good work again, sorin is a great guy, does his job super and also explains it well. Top!!! have been watching for about 2 years and keep learning. thanks for that.
Hi Sorin. Its been a while since I watched your videos. 4 years ago, I spent 1 whole year going over your videos 1 by 1 digesting all your ideas, your shared experiences when it comes to repair and electronics. Ive learned a lot. Thank you. Now I can share you a little bit of knowledge when it comes to macbook. I have resources of those stuffs. Macbook schematics and boardview.. The idea of macbook is that it starts with the power rail PPBUS_G3H. This is the main power supply rail coming from its charging ic or U7000 After the adapter. Next is the PP3V42_G3H WHICH is the rail responsible for the green light. I can share to you my stocked knowledge in macbook. 😊😊 By the way, that model is prone for lcd issues, image issues etc.. that is fixable as long as its not a faulty lcd.
really nice, let me know if you are sharing - also an independent repairer
@@Mazeisaspace i haven't working out yet of my channel 😊😊 soon if I have enough time to do so as well
Watch some Louis, the site name for schematics is in the watermark of his diagrams. I would link it but my last comment trying to help was deleted
@@emc2electronics60 thanks i know Louis Rossman - will check it out.
You did great jop with less tools no schematics of boerdview you are really genius wise man.
Thks Sorin wanna consider this my job for repairing laptops, greetings from Uganda
i love the lesson learned... you are a really honest guy! it was a tricky repair but you accomplished like the pro you are ! thanks for sharing your experience with us!
Great video as always, love seeing you use your skills when you don't have a schematic. But just so you know for the future, that model definitely has a schematic freely available online, on places like badcaps.
Such a very good tech. Ive learned a lot from.
Can you show how to fix laptop comes on for 8 sec. then off then on or vice versa. I already flash d bios but same thing.
Like! As always. You inspired me mister Sorin. Thank you!
Thank you from France, I have the same problem here! and you saved me ;-)
Also watching air crash investigation very interesting, i have seen and recorded all episodes, locked up abroad is also very interesting
The flight channel is best...
I am really surprised that you do not have a thermal imager. There is enough of a business case, in terms of increased productivity, to recoup the cost very quickly. Your fingers would appreciate it as well.
focus always he said..tnk u so much master.
Need more videos of macbook repair
Greatest repair tech ever! If it's fixable Sorin can do it! Thank you for another great video Teacher Sorin!
Noticed on ebay cat s60 mobile phone with built in Flir they go for around £240 second hand. Great video thanks.
thats the trouble wiht mac no schematics no nothing from them good too see you again in these week
Actually it is much more easier to find schematics and boarviews for macbooks comparing to many different PC laptops. Have a look at the Paul Daniels's work. Just search for PL daniels YT channel.
Great job Sorin, Minus one laptop to the landfields. Apple beeing apple, no big news! Keep it up man! You should made a Patreon account to help buy a proper FLYR camera!
41:06 right to the shorted cap there was a big black chip that seemed drying up quickly too. Wonder what that was. Anyway great video . Keep it up bro👍
Spring you have good eyes and not seem that old. Get some good led light for your microscope. I can suggest one from Northridge fix website.
Congrats, Sorin. Excelent intuition and job.
Without schematics, how can you know so quickly which pins of a chip should have voltage and which should be ground?
thank you Mr.sorin what a amazing videos
Sorin, go for a thermal camera. NorthridgeFix popularized the thermal camera.
WELL DONE
Sir..i really like your videos,i'm watching far away from Bangladesh. 😍😍
My bottle with alcohol is also always empty :-)) cheers
man that Alcohol trick is amazing, thanks for sharing mister Sorin :)
Great tech. on site repair not scripted.
Thank you so much. Ive learned a lot.
Real Channel !!! Sorin thank you very much for sharing the information
i swar,i love u man ,it's more interesting when u talk out repair :)
i learn a lot from you Sorin thank you so much always watching your video :)
You are awake at 4 o clock ? Wow how late are you going to sleep ? Thanks for the nice video's I learn alot of it :-)
Well done Sorin!
you know what magical about this video is that im having the same issue with a Lenovo gpu has power board comes on no picture no cpu voltage and i had the same idea as sorin the pwm controller need replacing lucky for him he has spares i unfortunately have to wait like 3 weeks from china yay
Amazing job as always.. keep it up..
1 question mr sorin when you plug tha power supply on on the pc how you check with multimeter?? Dc or ac volts..sorry about that but iam new here...or anyone who see this comment can answer me. Thank you
I think it is U8030. It´s pp3v3_s5 switch TPS22924.
Great stuff Sorin, enjoyed the watchalong.
Every video learning something from u. Hope i can open my own shop , greetings from Algeria ♥️
Two words if you are repairing Macbooks. Open source OpenBoardview or it's commercial version FlexBV along with boardview files helps to trace circuits in MacBooks. Neither software comes with the boardview files. I repeat neither OpenBoardView nor FlexBV come with the boardview files for Macbooks. You need to use Google to search for the model of the motherboard to find the boardview files.
Too right Greg M :)
Sorin, I added this repair to the Repair Wiki (repair.wiki/w/A1502_2013-2014_13%E2%80%9D_MacBook_Pro_Retina). Please make sure when doing Mac repairs that you fully state the board number and MacBook model. The A1502 has models from 2013-14 and 2015 (2 different motherboards). It will help to know the exact motherboard model in future. Thanks!
We saved the laptop!
Great job Mr Sorin...Master
Life saver big boss
Sorin beats rossman and daniels in macbook repair, no schematics involved
Sorin is great but don't be ridiculous. You are making a fool of yourself
@@MrPnew1 that is my opinion, Paul can't even fix his powerspply, and rossman can't fx anything without Pauls software :)
Smart and clean job !
i think why processor power rail is high voltage and contant at 1.9v because maybe because intel processor model with fivr fully integrated voltage regulator.. now intel removed that feature again.. maybe im wrong..
Excellent work again
Beautiful job
Much Better than Apple and a nice job
EID MUBARAK sir
44:44 1 year later, sorin buy a thermal camera 😁
Funny :))))))))))))
@@electronicsrepairschool good thing, save your finger!! 🤣
Sorin :"what is thingy?"
Fingers : "we want danger money!"
Thank you for this knowledge
Sorin can you make a videos about structure of macbook motherboard please.
Bien maestro.
You are the best.
Great job as always
Such a great video. Thank you for another job well done.
"if you have a schematic, let me know WTF this lil thing I replaced is!"... LOL! .🤣
Its hard to repair device without the schematic but replacing chip without basic test is not the smartest way, even that chip which was bad. Also you should change all corroded resistors as in one day that corrosion will eat rest of the pad. Think about quaility of your repair. It wasn’t great job but I’m impressed anyway about that you was able figure it out and fix that logic board without schematic, boardview or thermal camera. Don’t treat that comment as a hate
my master
Awesome!
Fresh video, cool mate.
amazing
To have replacement parts close to you. :)
great fix
People been dealing with Apple for over 15 years and still believe they will repair their stuff. Is like living with someone for 15yrs and dont know that person is selling drugs 😆
old fingerometer works well.
excellent is rarely found and more rarely valued from India : Great Teacher
Very Nice Thank you!
well done.
I've been busy lately, but I give you your first like, greetings from kentucky
nice to see u again mann
9 in the morning? We start work at 8 around here....
please make more videos about mac books 🙏🙏🙏🙏
Thats awesome. thankyou
Oh, now you compete with Louis Rossmann. ✌🏻
louis rossman the nyc sponsorship he h eh he
Great ...!!
I wonder why you still haven't ask your boss to buy a smartphone USB thermal camera for 300 GBP (I have one, its really fun!) or buy a broken one and fix it...
You really like to burn your fingers hahahaha
What do you think, will customs police believe Sorin when he explains to them why he doesn’t have fingerprints? :)
Can you help sir . I have a laptop with on keyboard power bottun .. the keyboard had damged with water and i cant found new one . How i can turn on the laptop with out change the keyboard??,
Any help!!
hello sir I need some help I recently subscribe to your channel because of your great work , now I have a problem hoping you can help I have an HP ENVY m6-n113dx laptop that I update the bios ... I would like to rollback the bios to an older version but it won't let me and I try everything that I know of, is there any way I can force write the old bios the only reason I want to use the older bios is that when using windows 10 it uses 100% of my CPU and everything lag the os even crashes
I ask me when will you ever buy a thermal cam ;-)
So you probably know The Flight Channel :D thats my favourite ;) what channels do u watch in terms of that aircrafts crashes?
