I am a Spanish speaker, I don't know how to speak English, the TH-cam translator helps me a lot to understand, I have learned more with Sorin watching his videos than other Spanish-speaking technical channels; Thank you Sorin for being very didactic and an excellent teacher
It's so impressive how these translation tools give us access to content from all over the world. The fact that I can understand comments from people speaking other languages is so fascinating to me.
@pepeluis670: If I feel too forced (work, shopping, a visit abroad) I speak English (with a Spanish accent or tone and I see the faces of my interlocutors... (laughs). Another way of saying it, since I don't want to lose any detail or sense of some word during the conversation in another language, I watch the videos twice, the second time in my mother tongue and with a notebook in hand. A brotherly greeting (we speak the same language).
You had me rolling with the whole uttra-sonic cleaner bit. 🤣🤣🤣🤣
Your ''ultrasonic cleaning H20'' is amazing 🤣 🏴☠ 😎 ❤
This video took me 20 years back while i was working for a chip level repair company where I used to do the same to the desktop and server motherboards.
Thanks sorin as every time your repairs are next level.
Hands down you are the best when it comes to electronics repair
better than northridgefix
@@robbirobson7330 There's no benefit of doubt on that! He's only good on slogan " better than factory"😀
@@robbirobson7330 I believe so , Alex is skilled but everything just about the money, He won't dig deep after 20 mins deem no fix and charge the customer repair attempt fee. I understand time is money but at least try bit harder for the sake of the dignity of the business .
@@Customer22374rt its all shorted caps and mosfets. when i was in the business probably only 30% was shorted caps or simple repairs. mostly we had defective chipsets, video chips, northbridge southbridge etc, pwm ics or something complicated. The business is never like they show on youtube.
Even a hospital would envy that state-of-the-art sub-sonic cleaner (AI) that you have.
Sorin, love your videos and keep up with the good work, however, I'm a bit sceptical on using plain tap water on electronics. When I did electronics back in the day I was told to use de-ionised or distilled water to avoid mineral deposits on the contacts of the electronics and short when water evaporates. Well done mate! Bravo 🎉
Just look at Adrian Black from Adrian's Digital Basement who is washing all his computer motherboards with tap water, just putting them under the shower. You can see that for a brief second in any of his videos, in the Intro. No problems so far and he washed hundreds or maybe thousands of them. He talked about this and showed the process in some of his videos. And he is not the only one who is doing this. Maybe tap water is not the perfect way to clean, but it's working. A isopropyl alcohol rinse after washing it's advised.
Not really relevant, but thanks for your inputs
de-ionised or distilled water would be better because of residue that can stay after tap water.
@@doruciobanu2261 how is it "not relevant"? he told you about a guy who uses tap water without issues.
I'm looking at your nick, is it just a case if balkanic stubbornes?
Tap water is fine. Repaired hundred cashregister mainboards that had liquide damage (pubs).
The trick is the drying, we always used compressed air to blow away the water an dry the pcb.
My 2 cents.

Perhaps the speaker is shorted (by the liquid damage) and caused the chip to fail. So Sorin you use the same make of ultrasonic cleaner as I do.
Уаау! Ультрасоник )) Сорин как всегда удивляет и учит быть проще! Спасибо, Сорин!
I had a 25mm chain gun in the US Navy that stopped working and I suggested to my shipmates it was the blackbox that was faulty. We say blackbox because its hands off. I open it to find salt water inside. A good rinse in fresh water for awhile and a nice hot hair dryer and the bullets were flying again.
I always wait for the "WE HAVE PICKCHUR!!!" and I'm almost always satisfied.
You do real electronics repair. Not very many technicians actually repair the PCB. A lot of them are board changers.
Best ultrasonic cleaner ive seen so far 👌 👏, Lol. As always another great vids.
LOL - love the 'special solution' you use with your 'ultrasonic cleaning' - your hands moved so fast I didn't see you oscillating them at 30KHz!!
I loved the sub-sonic cleaner!
You are the best mobile electronic teacher ever
Am a Nigerian but your videos have really been a life helping for me
Thanks alot
Well done sir, salute to you
omg the state of that macbook 🤯
great fix sorin ..thermal camera to the rescue ...but we know that you would have found the faulty chip without it ...petrol and fingers ..
we need new video with petrol and finger
Are you going to replace that chip?
love the sub-sonic cleaning machine 😀
I love your ultra sonic machine😂
Is the schematic from rossman?
you almost got me with sub-sonic cleaner 😂
Good job mate 👍
That's not water damaged he's been keeping fish in their 🤣
Nice find! 😊😊😊😊
Much safe is to use distillate water or deionized water
You probably blew the audio ic! Do like Rossmann: after cleaning with water put the board in alcohol an bake in oven 20 min at 80 deg C., so all water has 100% evaporated. Now connecting to power is safe ! Just my advice. Nice video sorin as allways....
How did the sound chip die? One possibility is there was liquid damage, it just wasn't that noticeable. Another is that while the board was being washed some of the sugar solution from the cola or whatever it was got under that chip. But ultimately - who knows? Great video.
Wooow impressed. He could have went straight for the thermal cam with that low ohm main power rail. But the issue for me is how he has access to the board view?? Where does he get that info? Would love to have this also
Probably from rossman
easy to find on google, I have many boardviews collected on multiple years
Well done Sorin yet you got out of another sticky situation. Great saying to.....We have picture. 😂 great education 🎉education
(16:25 - 16:35) In this case, the thermal camera leaves no room for doubt: IC TAS5770ACO running HOT but without its previous fault analysis work... PCB "doesn't know how to float"? That was not a problem today for an expert aquatic rescuer (Sorin is his name?)... a most sincere congratulations. All the best.
@user-bh1: on mouser TAS5770LCOYFFR (3.32 each piece). 820-02020-11 motherboard on Ali/ss (approximately 550 bucks, whew).
@@AzuaraRuiz-md1bi : Thanks for the info. I went to check the mouser page and you're right (3.32 bucks), the only thing that puzzled me was that when I downloaded the datasheet (right there on the mouser page) it references this part number TAS2770. I saw the schematic for each terminal and it corresponds to a 30 pin IC that uses reballing like the one in the video. Another way of saying it, so TAS5770LCOYFFR = TAS2770 (they are pin to pin equivalent) and both made by Texas Instrument. Again, thanks for your answer because it makes us investigate (deeper) and that's how you learn. Motherboard? Yes, it is very expensive (prohibitive). All the best.
Nice job.
At first I thought Sorin is not joking but yeeh Sorin is joking right H2O in a bucket😂
MacBook loves water, coffee , milkshakes
@nickhaldem9626: Also beer, sweetened tea, any liquid; and sometimes behaves like a "parachutist" (landing on the ground).
Hola Sorin , soy de Argentina y me llegó para reparar un equipo igual A2338 , por derrame de líquido, el dueño trato de encenderla varias veces y luego de funcionar 5 min se apagó. Cuando la abrí, se veía como esa, conseguí limpiar todo . Pero el conector de power Charger estaba en corto, así que quité el conector ,para mí sorpresa está quemado en el motherboard, logré retirar los pines en corto , y encendió. Pero ahora no carga la batería y en la pantalla sobre el lado inferior izquierdo hay como una mancha. Puedo preguntar dónde descargaste el esquemático?? Desde ya muchas gracias. Estoy aprendiendo mucho contigo!!
can you make video about macbook power sequence
nice one ,... why aple need schematics to repair?
my best teacher hahaha
Hhaha, that Sub sonic cleaner make my day...
No capacitor no problem, no speaker chip no problem. Rename the channel to Electronics Comedy Standup Channel lol.
It's like music to my Titanium implants.
My MASTER.
what are those app are u using for maps?
You should get one of those "back massagers" shaped like an egg and plop it in the water
Thanks for sharing sorin❤.looks so bad only for audio ic..nice one" ultrasound cleaner"😂😂
hey sorin, does the audio work without that chip on both speakers?
i think the cheap was heating up because there were some water trapped underneath it and it made a short on the chip, just don't use tap water like that and after using distilled water rinse with IPA and heat up the board a little much more so that the remains of the water evaporate completely.
I doubt it because the board wasn't working before the rinse either.
is isopropile alcohol
Fine "digital" technology generating subsonic waves. It never fails.
WOW.....NICE SUB SONIC MACHINE.... A DODGY ONE AND VERY EXPENSSIVE TO.....🤔🤔🤔🤔🤔.....🤣🤣🤣🤣🤣🤣🤣..... NICE VIDEO👏👏👏👏👏👏👏
hey, a coke spill made my playstation one load 4x faster. (no idea how given its cd based). only went back to normal after same person who spilled the coke dropped the playstation 😂 proper calibrated spill that one.
A solution of 40% Distilled water and 60% 99% IPA to force the water to dry quickly and not linger also does wonders on drinks etc
You can buy 70/30 IPA/De-ionized water in a spray bottle and as wipes too.
If you had a donor chip can you get that audio working?
Sure. Just reball.
Magical✨🎩🔮
Hello🤝 quite a mess on this board but I knew you could do it, the best was the ultrasonic cleaner🤣😂😂😂🤣😂🤣🤗👍👍👍👍👏👏👏👏👏 greetings👋👋😵😵😵😵😵
it better if u show motherboard disassembly of mac, really worth
Come to Beşiktaş, Sorin..
Use a Audio Spliter..module..Bodge it..
Why did you say it required ultrasonic, but then you just cleaned it with a toothbrush?
It’s called having a sense of humour 😂
Was that Holy water!😀
👏👏👏👏👏
💗
Hold the toothbrush by the head with the bristles facing up. Steal your wife's hairdryer if you don't have a hot air station. Warm the shaft of the toothbrush just the other side of the bristles with the hairdryer without burning your fingers. The toothbrush will bend and you can get up to a 90 degree angled head. Much easier to clean around tall components.
No speaker no problems... Yeeee. 😅
If you can tell me how to move my finger 30,000 times per second my wife would appreciate it 😊
You are a legend, fantastic joke LOL
🤣🤣🤣😄
@Mark.c1: lol. You are terrible. LOL.
😉Some safety rules for the beginner electrician
Rule of thumb number 1 Never put your fingers in dark places. You may be electrocuted. Rule number 2 Finding the fault 3 Solving and creating bypasses....
for example Transistor PNP C.B.E .. .B loose there is California rosin in a secret mix .....") that repairs everything from PC corrosion damage.
Only health and happy life for everyone.
Stay away from oxidation = (soda cola products) less sweet
Against corrosion > sports = running 10-20 minutes a day before eating.
Against overheating > don't eat two hours before bedtime

3:44 LOL
Sorry with all of my 6 years of expirience of electronic repair all i wanna do is hurt myself
Now you are dodgy grandmaster 😂😂😂😂
Sorin it's looks like salt liquid
So hard knowing when you are joking lol
Probably the customer in his/her/whatever mind: But i thought it can swim, Apple says these things can do anything.
tell me you used distilled water. please. Hello? distilled water right 😨
Coke in the speaker? Will probably blow the next chip unless replaced
@teslasapple: Yeah. Completely agree. They are cheap at mouser electronics so I would install a new pair without hesitation. For some recent Dell & Lenovo models (both Chrome) the audio ICs are not easily found on the internet. Greetings.
Sperms on MacBook, classic 😂
H20 sounds cheep, better use Dihydrogenmonoxid for billing - doubles the price.
Sub-sonic cleaner... 🙂
wOoOoOoOoOoOoOoW😱❤❤👍👍👍👍👍
20:38 HE PLUGGED IT INTO AN AMP AND FRIED THAT CHIP NOW HES GONNA PLUG INTO HIS SOUND SYSTEM AND NO LEFT CHANNEL. REPLACE THAT CHIP QUIT BEING A HACK
What do you mean : he plugged it into an AMP? I dont see anything wrong from sorin?
This is an amplifier for the internal speakers only. There will still be stereo sound if using an external amplifier. Quit criticizing if you don't know what you are talking about.
@@Alobster1 what critic? i just asked some questions. Looks like have some issues my friend! Very negative personality. Good luck with that!
Where is shampoo😂
how the IC got shorted??? really? isn't it obvious enough? maybe the speakers got shorted by liquid? you should check them frist, then resolder the new IC
lol i caaaaand belieeeeffff
I will NEVER understand how someone could treat something so expensive so poorly. I've never had a computer die on me. Every one of them was used until it just didn't meet down for what i needed it to do. I'll just never get it.
Same here, but my daughter spilled something on my expensive laptop. I took it to get repaired, but the repair shop didn't have Sorin. They just told me to order a new laptop because it was liquid damaged and beyond repair. At the time I took their word for it. Never again.
Whenever Sorin fixes macs he is very sloppy. You start by looking at the power rails and go through the list. With schematics and boardviews available its very simple to follow through in a methodical way. Like louis rossmann does. Sorin is great with PC laptops when he has no schematic but unstructured when it comes to macs.
Dihydrogen monoxide - lol -.
lol
22:22. DON'T GET ALL HAPPY.
YOU SHORT CHANGED THIS GUY. YOU DONT LEAVE THE AMPLIFIER OUT. YOUR JUST GIVING YOURSELF A REALLY BAD NAME. AND PEOPLE ARE THROUGH
WERE GONNA JUST UNSUBSCRIBE
Sorin. He said these components are expensive. The customer has to decide if he wants to pay for a new chip or if the main thing is that his computer turns on and goes silent.)
bye-bye
Box of chill-pills, anyone?! 😂
Would you rather have no laptop at all or no sound on one speaker? I would chose the latter. It is hard finding chips for apple products and if I was the customer I would rather have my laptop back now then wait over a week for a chip. They will still have stereo sound with an external amplifier.
Send your MacBook to Louis Rossman, he will charge you 1200 dollars and replace the amplifier. Sorin got this job from a local "repair" shop. That means fixed fee. Probably 60 pounds or less. He cant waste time in replacing that stupid chip. He did his job. The MacBook is turning on. The customer can recover his data.
