that ending is out of sync, maybe youtube uploading/processing acting weird
CZcams messed it up as always when I tried to post edit in CZcams editor. Video is still processing after 10 hours. I contacted CZcams to fix
@@NorthridgeFix thanks boss
@@NorthridgeFix : Wait, wasn't that the asus laptop with the liquid metal spillage? If so, it might return again.
Looks like CZcams fixed it.
I just wanna say thanks for all your videos! Yesterday my Ps5 controller started to stick drift and I ended up switching out the potentiometer from a working donor board. I used all the tips and tricks i learned from your channel and the controller is now fixed. I have tried to do that in the past and messed up badly. Thanks to your channel, I was able to get back to gaming. I also saved the world from complaints by getting rid of the messy solder. It is now better than factory!
Its refreshing to see a business honor their warranty than make up some bs excuses. I respect this channel even more
Nice to see great customer service and stand behind their work !!
The ultrasonic and IPA, is actually a way to clean some aircraft parts. I work as an airforce tech and we do it often
Yep warms up quick too - with no heater
what is ipa a beer?
@@aljosakrojac9085 haha, well it is, but we're talking isopropyl alcohol
What aircraft parts would you clean in an ultrasonic cleaner with IPA?
I have been in the electronic repair business since the early 90's repairing mainly TV's, VCR's and so on, I still repair LED TV's today, your soldering skills and diagnostics skills are insane, LOVE you videos, from Melbourne in Australia... keep up the great work.
Alex: we fixed that board.
Asus: I'm back bro.
Alex you mentioned a viewer talking about using IPA on the ultrasonic machine, let me tell you something it works awesome, yes you are correct it's flammable so use at your own risk.
I get up at 5:00 am central time for my coffee fix and Northridge fix and never disappointed! Wouldn't mind to see some of big boss teardowns and reassembling. Thanks 😊
5:00am no thanks😵😵😵😂😂
Good job, Alex. Great to see you stand by your warranty, even when the unexpected (repair return) happens.
Alex, it nice to see you stand behind your work and give him expedited service.👍👍👍
I just wanna say thanks for all your videos! Your soldering skills and diagnostics skills are incredible. I think about to change my business, but I have to watch more vids of you. ;-)
Now that's service, Another fantastic fix. If i lived in the US i would ONLY go to this shop for repairs! :)
We used to use Closed cycle IPA UltraSonic cleaning baths with a refrigerated top condensing fume capture at a Military PCB production factory back in the mid 1980's. we could clean boards upto 50cm wide. They are nice bits of kit, but are expensive, so not suitable for a small business.
Good job. Glad you're not getting a lot of repeat repairs under warranty, it kind of proves your methodology works. Which is reassuring for all the component level repair people out here (myself included).
I'm feeling scared to buy an Asus laptop after watching there are lots of motherboard issues.
You should be. Forget laptops. Get a desktop.
I have an Asus laptop and I do not recommend it at all. Everything about it is bad
Almost all their devices have had issues. I remember the previous zenfones getting bootlocked for no reason.
Not practical or economical to fix a desktop motherboard.
My asus laptop monitor died in 2 years
you could have been a comedian in another life . Pretty funny stuff you say 🤣
Impeccable work 👏
Thanks for all the lessons
Merry Christmas and all the best to you
Thank you for sharing your knowledge. But, Alex. The A3* chip you changed should be a mosfet driver/controller. The one you looked up is a dual LDO linear regulator.
It's the same chip, call it whatever you want
The chip is actually a NCP81151MNTBG, but he is right about both A3H & A37 being the same chip; the first two digits are the product code, the third one is the date code
@@NorthridgeFix I am a bit woried because A3H chip was little bit damaged on top left
@@frenkie0902 That's just the outer case covering the chip. It helps to dissipate heat and protects the chip fom UV light and physical damage. The chip itself is most likely fine
Yes, you are right. I discovered the same thing.
Yea man u seem legit my ps5 been doin good so far but recently had a hdmi problem were it came on but was saying no signal on tv I messed with it a bit it came bk on eventually worried its early signs of my hdmi connectors going out nice to see u in Cali as I am Atwell will be sure to hit u if need to fix my stuff
Amazing and interesting work. Great video, thx. Happy xmas to all of you in the shop. Have nice holidays with your family. Greets
We want more videos in a day from you... 😊
It's fair. You fixed it and there was an underlying problem. Took a week to show. It's not feasible for you to test every device for 2 weeks. It all works out, nice job 👍
"The customer paid for expedited service when he brought it in so we're still going to give him expedited service to re-do his laptop." Puts a rush on a warranty. Not something you see very often. That right there is quality customer service. You're the man Alex.
Respect the man who fixes the impossible. Love the videos.
Another great video, Wish I was local I am currently in Philippines but i have a MSI ge72mvr 7rg the motherboard popped a mosfet as well. Love your videos Merry Christmas and GOD bless
Keep up the great work happy new year 🎉
kind of epic, i had a acer aspire motherboard with the very same issue. thought, it took me a darn 4-5 weeks to shove my face to the controller chip. Good work, nice that you knew of the issue. i didn't
You're the man wish the best for you and your family.
معلم يعطيك العافية ، سؤال سريع: محطة اللحام الصينية اللي بتستخدمها بتنصح فيها مقارنة بالHakko 951؟ تقريباً نفس السعر.
Thank you Alex ❤
Uve got a new sub here.. Like ur vids.. Keep it up👍
Btw have you thought on buying a ultrassonic machine for cleaning boards?
I've experienced the same/similar on digital commercial tape drives in the 80s in manufacturing in Monrovia, CA. Usually the output power devices will blow and replacement of the output transistors of the preamp will resolve the issue. In a few cases, uncommon, the pre-stage drivers of this preamp to these output transistors on this same board will also blow. The tape drives are soaked for 2 weeks, drives will usually fail well within this soak environmental test. Most common are the power transistors of the power amp, a separate circuit board with a huge heatsink. The TO3 transistors will blow probably because of an imbalance. Sometimes this will damage the output of the preamp board.
Virtually all failures are power related for power supplies, controls, sensors and tape drives. Seldom does a logic (chip) fail (probably less than 1% of all failures) because back in the day things were comparatively conservative. Today chips and near components do fail, consumer goods, because they are basically overdriven or overclocked.
It was a time when virtually any schematic, pictorial diagram or perhaps theory of operation could be had for any product. The days when Heathkit and others like it were still around.
Great viewing thankyou.
I'm going to have to learn how to look up IC numbers and find the associated data sheets.
I'm actually STUPID interested in the difference between A3T, A3H, and A37. like how are you not at least going to tell us where to look it up? lmao
Great job bro 🎉
But for more safety you can ask the customer to bring charger also and check, could be faulty charger
Keep us posted on this job
I think big boss's job is REALLY amazing, it takes a lot of patience to dissemble an reassemble electronic devices.
If you you wanna verify this, try to teardown a laptop...or a smartphone...
BIG UP BIG BOSS !
how do electronic components short out ? why does it short out ? what cause it short out ? a big fan of you watching every single video you upload . pls mention my question in the video or just reply to my comment . love your content because i like your personality .
Does the T3B soldering station come with soldering tweezers or are they available?
Great video.... Like always.. 👍
@NorthridgeFix Its not enough for the laptop to be on, you need to stress test for 15 mins to make sure that chip doesnt blow out again when under heavy load.
finally my answer to where to get the same hot tweezers...
So where do you get your donor boards from? Do you buy them? Leftovers from no fixes?
What is the white almost like a light salt crust on some
Parts of this board, similar as you see on a sailboat after being at sea for a short trip and getting sprayed by waves?? Ps thanks for the interesting video's that show your work
i would absolutely advice against using IPA in an ultrasonic cleaner. this is used in a very controlled environment and not for the common person. it is a highly effective way for cleaning but it is very dangerous.. stay away from it if you do not know what you are doing. do not do this at home.
It's always good to put all repaired PC on stress test maybe for 1 hour, before shipping to customer.
I use IPA in my ultrasonic cleaner all the time to clean resin 3d prints, it's what works best. I don't use the heating function though.
Keep us updated, if it comes back again please. By the way, I've asked many times the title of the outro tune, if you don't want to say, could you at least extend one of your videos to include the full track?
i understand your english so easily
While it is not best practice it's actually a very common thing among smokeing culture to clean different bowl pieces etc with ever clear in an untrasonic cleaner and it does magic even being flammable
I noticed a blue silicone work pad at the @13:04 time mark in the video ..... That one is bigger than the one in the web store..... I have the one that's in the web store .....But I can't find the larger ones ...... Are they available here ???
Man, ASUS really cheaps out on power management. Almost got an ASUS laptop in April but decided to pay a bit more for Sager. Thank freaking god...
Thanks!
I just noticed that after 12:50 the audio and video are way off. You are talking about the PDF of the documentation of that chip you replaced while you were showing that the laptop was working. And your intro played while you were still talking about it. Also the timeline on YT ended but still kept going so for the last like 20 seconds there is just a black screen. I don't think as it's my YT bugging out as it persisted after a page refresh. It isn't video-breaking but could you please fix this? Other than that I really like what you do and I still find it amazing how quickly you can fix devices with your knowledge!
Check pinned comment
good customer care full marks
Chip makers take the purest silicon crystals and make them work by introducing intentional defects. It's amazing they work at all but even more amazing is what has been driving the development all these years ... our desire to play games. Thanks for all your videos Alex. You are a true Jedi Knight with a soldering iron
Be the Force with him for ever...😀😀😀
A pure ingredient does not a cake make. Or a chip, for that matter.
The video finish like 40 secs before the audio... weird thing. Still a good useful video thank you.
Well crap.. I recently got an Asus laptop but it's a ProArt. At least Alex is getting alot of business from failed Asus laptops and with any luck he will have enough experience with them to find a surefire way to fix many of them. But I have a feeling it's sadly a case of cheap components causing the failures or even worse flaws in the motherboard. The parts shortage is a good excuse for companies as well I suppose..
Alex you are sooo right on Weller getting extremely overpriced.
Yes, Weller stuff ist still the professionals "wet dream" kind of tool, but as its so overpriced and not affordable - people should try to get better value/money relation from other manufacturers.
I'm sure there are a lot of pros also watching these videos though. I just don't think they're the majority, is what I mean.
i hope you the best buddy keep it up .
why does it feel like Asus is slipping in the laptop department. I had a friend who brought me his Asus ROG Zephyrus S15 GX502GV and it was running so hot, temps are at 100°C+ on load. All pads have melted and on one side of the VRM, the pads are not even making contact. A good set of high end pads and TIM lowered that by 20°C.
Do you repair circuit boards for GTO gate operators?
Good job !
very honest re do under warranty
any upcoming episodes on the house hunt?
The A37 and A3H are likely OnSemi NCP81151 MOSFET drivers. The "A3" is the real marking the last letter is month of production, so it doesn't matter.
This video is just the answer to the question of a certain commentator, why you should replace the mosfets in pairs and the driver. They should be replaced so that laptops do not return for a complaint.
Hi there.. I am one of your subscriber always watching from PHILIPPINES 🇵🇭🇵🇭😊😊BTW merry Christmas to you and to your family .. If you don't mind how can I message you personally coz I have to ask questions personally
i like your point of view ;)
T3D is incompatible with hot tweezers. so it does not really compare with the Weller, right?
Ultrasonic in IPA and even acetone is common in some industries. Just don't use heaters. Not unsafe. That said I don't ultrasonic populated boards.
That board view at 4:00 shows a lot of "muck" over the board. Do you clean such boards, as the dirt could cause short-circuits and strange behaviour.
saving the world from complaints, one video at a time
I have a question. I can see the use for a zero ohm resistor when you need to hop over another trace on the board, but what is a zero ohm resistor's purpose when not hopping over another trace?
Could possibily be used as a fuse
Some mosfets may require a bit more gate driver resistance to dampen risetime and ringing. Usually not more than a couple of ohms. I guess they leave them in to keep the flexibility of changing parts, just in case.
2:47 Phenomenal service right there.
Common sense is such a rare commodity. I thank God that my father was very hard on me and showed me common sense every minute of every day.
Nice repair.
You just don’t run the ultrasonic w/ heat when using alcohol. It’s a very common practice.
Superb😊
ultrasonic with ipa works just fine
Was i? About the ultra Sonic?
Hope not, cuz to remove vaseline from motherboards after NL2 OC on motherboards works very good.
imagine if big boss had an assembling channel also, super cool
Great job
That will be a lesson to that computer to stay fixed! 😅👍
I like your video's!
Came back for same problem.
Right to repair in action. Of course you'll need several years of experience and the right equipment, but it is still possible.
What is that site to find components and datasheets?
plenty of websites for components, (e.g. mouser) but thats part of an electrical engineers work - source components and read datasheets :)
Same happend to my tuff 3070ti after week.. change the mosfet and in a week same mosfet again ..
nice repair
Some things are just not worth working on and Asus laptops is one of them things In life
Hi, what is the purpose of the zero ohm resistors in this instance?
Hi! This is from Google:
"Zero ohm resistors are the perfect remedy to 'magically' route a single layer board. Rather than making holes and turning the PCB into a double-layer structure, you can route a trace between the pads of a zero ohm resistor. These resistors are then assembled along with other components during the manufacturing process."
They are used as "jumpers" to route traces over other traces on the same layer
@@Exarhadsgfds yeah but i dont see a trace going under the resistor so i thought maybe there is another reason
Great double check, next time you can check 10 minutes on power mode.
Absolutely unrecommended to use ipa in an ultrasonic. Some people do it (Kingpin from EVGA for example), but even he doesn't recommend that you follow his lead, it is dangerous.
O carregador do cliente pode estar com defeito, já estraguei um note com carregador defeituoso.
I think asking "why?" would have prevented the rework.
I like this guy , he’s good at what he does . Can you hire me ? Maybe I can sweep the floors or something
What is solution for Lenovo think center power saving mode
Considering you have replaced the chip a few times already, you sure do leave next to no damage even under microscope !
do not dry the ipa with a dry stick, u will leave fibers all over. After cleaning with ipa, u can blow the remaining ipa away with hot air (100 C). It will look better.
well that's because there is still some flux residue left behind and it becomes sticky. if you keep on cleaning 2-3 times the spot there will be no fibers left. but i understand there is not a problem if just a little flux is left over, even from the factory sometimes it has on laptop motherboards (near solder jumpers etc)
