How sweet of your daughter. Alex, daughters love their father the most
I can watch this dude for hours. It's very peaceful and gratifying when he brings junk back to life.
Love to see the smile on your daughter, and your face. You can see the love. I lost my daughter right before her 16th birthday just under a year ago. It has left a hole that cannot be filled. Spend as much time as you can with her and hug her tight. Love your videos keep them coming
sorry about your loss brother....i have 5 years the only daughter.
How are you doing Eddie?
@@MadMax-yq9ix I'm hanging in there. It's something I wouldn't wish on anyone. I know she watches over me, and will be there waiting when it's my time to go. Can't fear it now since I have most of my family ready to welcome me home when it's my time. Hopefully that is a long time from now as I still have many things to do, and people to help. I appreciate you asking. I hope all is well with you
Sorry about your loss Eddie
You're one a kind Mr Alex, whenever you are online or uploaded a new video me and my kids quit everything we're doing to learn something from u. Thanks immensely.
Your kids are going to get really smart watching content like this. They have a bright future ahead of them.
your child will be the next bill gates
@@ShamblerDK big time!
"I'm not pulling those numbers out on my.... Lets continue with the board." 😂😂
Yeah, I chuckled when Alex said that line, knowing full well that he omitted the a$$ word. This man is just great to listen to.

How beautiful child and father relation. I am happy for u sir
That was really beautiful to watch/see. Alex is a great father. He can be very proud of his beautiful daughter. Fred
You are a good father! That was very sweet.
You tech's that do this micro surface mount stuff are literally like surgeons. It's fascinating watching what you do. :)
Even though it was not an easy fix I love hearing your thought process and knowledge
Looks like the chips internal VREG5 blew up. Closest capacitor to that pin might be bad. VREG3 and VREG5 are active even when EN1 and EN2 are disabled, so basically they are always on when input power is applied. Something may be shorting VREG5 to ground. VREG5 and VREG3 are 100ma Linear Regulators that output 5 V and 3.3 V, respectively. The VREG5 provides the current for the gate drivers. VREG3 functions as the main power supply for the analog circuitry of the device. A ceramic capacitor with a value of 4.7 µF or larger (X5R grade or better) is required for each of VREG5 and VREG3. It should be placed close to the VREG5 pin and the VREG3 pin respectively to stabilize the LDOs. These ceramic capacitors are the first components I would check when the VREG5 or VREG3 pin blows up like that. Closest capacitor to that pin might be bad.
Cap should be something similar to this part#: GRM188B30J475ME84
Like this post so that Alex sees it please.
Hello i have exactly the same problem, vreg5 is Vin or the main power rail so i guess it's a capacitor as you said
Your beautiful daughter.. May God prolong her life and protect her.. and may God grant you long life.
Wow amazing that you caught that moment on video. Great video as always and your daughter is so sweet to bring you a drink.
Alex Sir, I really enjoy learning from you. I watch your videos often and certainly enjoy learning from a genius! BTW, it was great seeing you interact with your sweet little girl. I raised 2 of them and have many grandchildren. I know a great father when II see one. Blessings on you Sir!
Good health to the family from Romania! I follow you and learn many things from you!
What a down to earth guy you are with a wonderful daughter making papa a cup of something to drink. Great video, thanks very much
Like you, your family is very generous and giving. You can say I raised my family right!
Very informative video as always and seeing the chip blow up was glorious to be honest 😂. But, the best part of the video was where your daughter got you your coffee. I am only 15 years old and I always help my parents, even if it is small things like getting groceries and seeing them smile is the most rewarding thing. When I see children help or get something thoughtful for their parents it makes me very very happy and makes me do much more for my parents.
Awesome video, keep it up!!
Todays schools teach kids to despise parents in the finest tradition of marxism.
That was very nice of your daughter to do that.. she thinks more of you than just a standard repair tech for everybody else's bench... The Big Daddy does help
Soooooo sweet, we are lucky man, I love my dauthers so much, just like I saw you enjoying the love from them, great work my brother
Your daughter is blessed.
Congratulations my friend to you and your family!!! I love watching your videos!!!
Thanks for always posting quality content! 💜
Beautiful daughter...god bless her...
You daughter is growing tall. I have been with this channel for a very long time. always respect and I learnt a lot from you. 💯NorthridgeFIx.
Love seeing your little girl.. It puts an even more normal quality to you... Though the board wasn't a fix,, was still nice seeing a good kid..
May Allah protect your daughter and the family. Truly love your work. It always amazes me how things work and how they tend to fail
Awww . A great dad too
a lovely gesture from a lovely kid
I used low melt solder for the first time today. Nearly soiled myself when the USB connector just fell in my lap so quickly! And didn't even use a fraction of the low melt I applied.
Low melt is the bomb.
I loved seeing you and your daughter very sweet. Love your work keep it up.
Happy to see you with your daughter. Mine is my live and joy, makes my day if she visit me on my work.
I Felt your pain when that chip blew up 😲
Loved seeing you with your daughter.
24:58 When a coil gets hot as you're injecting power, try injecting on either side of the coil. A coil can't go short circuit (to ground, a coil always has low resistance), but it's probably on the path to the real short circuit, so when you inject on the other side, the coil is no longer on the path and the real short circuit component should heat up.
your comment didn't make sense to me...
@@blocky3664 What Alvin is saying (writing) is that when you inject power into a short circuit, through an inductor, the inductor will heat up unnecessarily due to the inductor being just a coil of wire wrapped around a ferrous core. By injecting the power into the circuit, while bypassing/jumping over the inductor, the hot spot(s) will be more representative of the actual short location, since having the inductor in series with the short, while injecting power, is certain to generate heat in the inductor (unnecessarily) and Alex will be able to see the real source of the short with the thermal camera. I hope this helps you understand what Alvin meant. Fred
@@blocky3664 me too man. Coil and capacitor are connected in one line so it doesnt matter
Its not correct to inject voltage in bouth sides of a coil, the right thing to do its to measure ohms in both sides and inject to the lower one, or retire the coil.
@@blocky3664 He says injecting on the other side of the coil to bypass it. But doesn't matter imho, the outcome shouldn't change as the coil allready is low resistance. Like injecting before or after a wire, shouldn't change anything.
a good profession, it's a pity that there was no Internet before
Your daughter is so cute, and she obviously cares about you. Count your blessings.
Incredible job troubleshooting Alex! Hopefully you can get this one working again! Rooting for you on this one!
A Good Repairman, A Good Father.
Adorable daughter. So sweet 😊
bless your children man. you ruin your eyes and your back all day over goddamn machines for the sake of their well being. keep doing what you do for the higher purpose.
All the work , your enjoyment/aches is worth it's cause
At this point i think that the intro of your channel is "here we have an asus laptop..."hahahah great videos keep doing this job, cheers..
Good job mate.
After the chip blew I’m waiting for the words “and now we have another doner board, that’s great.” 😂.
Kid saves the day with a Coffee.. nice one salut.
Your daughter earned a Like 👍 🥰 caring is sharing.
Have you memorized the pin out on those Mosfets? I'm impressed. I liked old electronics so much better.
Many pads under the destroyed chip are connected together by solder bridges, suggest to clear that area before any further measurement。
I thought that the new solder blob on the ground pad when the chip was replaced was on the large side at 10.56 and did wonder if when pressed down it had created a short.
What looks like bridges could simply be flux between the pins and the glare from the lights
That was glare
@@NorthridgeFix VIN and vreg (if not mistaken) are fused together tho, you even lifted them.
The pads were like Hiroshima and Nagasaki melted together.
I don't know this chip in particular, but a quick Google search shows VREG5 normally has about 5V generated by the LDO.
If VIN (which was 19 volt I believe?) was connected to the 5V rail, lot of components on that 5V could have died as well.
But I hope I am off by a mile and you get this laptop running again, even tho it would be more complicated now than it already was, sometimes you have to do 1 step back to do 2 steps forward :)
You are truly a nice guy. I wish I had 1/3 of your knowledge. Nice to see your family in your videos. So cute! You deserve all the success that you receive! Love your video's and you sharing your knowledge.
I do electronic repairs as well. I know the frustration. The struggle is real!
Excellent video Alex an exploding chip live on video as it happens brilliant !!!! Not by design though LOL ?
Mashallah your daughter is blessed to have a good dad like you.
I bought 2 ASUS products, both of them stopped working, after 2 years, i switched to another provider, and see, no more problems! If ASUS will react some day ? LUL.
Thanks for that great vid again. Awesome guy.
This is a very interesting part 1 repair. =)
Hey! You got great kids! Congrats!
Excellent video, as always! 👍
Nice to see Your daughter to bring morning drink to father! My daughter is helping me every time too.. 😇
At first glance, looked like You short out two voltage lines with multimeter probe, but rewatching part of video, shows, that You barely touched one leg.. Mysterious situation, indeed. You touched it with probe, and chip blow up.. 😂 Never seen this before under microscope!
Thanks for sharing experience! 😉
Love being able to see the values on the multimeter, awesome job
you actually fixed the problem in 2:25 The broken capacitor escaped his attention.
Looks like it's just a dust particle or something.
I think its broken
So adorable your daughter brought energy back to you haha
Alot of our meters don't reas as fast as yours so thank you for the verification.
Compost happens Alex.
I love the bring your Dad a coffee/tea for the spilled one.
Best video so far
that gesture with the coffee bought more energy for 6 more boards right there
Good video brother and i learned lot of knowledge on your videos❤️
Your daughter... That kiss on the cheek was priceless.
I hope this gets second part.
Here we have an ASUS laptop... 17:58 & now it's better than factory.......😂😂😅
Very interesting video. A section for schematics would be very amazing.
I hope you can fix this motherboard. Thank you for that video, greets
Ohh brother finally one video pop up in my other phone . I hope you doing well . New sub
ماشاء الله ماشاء الله حفظكم الله والله اكبر تبارك المبدع الخالق كل الاحترام والتقدير لجهود والمعلومات الفنية اللي حضرتك بتقدمها بارك الله لكم
No smoke? no sparks? just a hole on the chip? Great video though, keep up the good work!
Just found this channel a few days ago. Was there ever a follow-up to this video?
19:58 I think the short is coming from those ripped pads after burning the chip the two pads are shorting due to that solder blob isn't it?
Has a Part 3 come out on this yet? I'm hyper intrigued!
ماشاء الله تبارك الرحمن الله يحفظها ويرزقها بركم
Shes so thoughtful bringing you more coffee xD
Nice!
Please make part 2 🙏🏻
You’re a good father and provider Alex, and a great mentor to us viewers on CZcams. Appreciate your time and advice. Cheers.
@NorthridgeFix that chip was heating up because a thing was shorting on the 5v / 3.3v rail. The enable line voltage will only be present if the output voltage of the chip is at 5v or 3.3v. Its a safety system for most laptops. I had the same problem with my old laptop. Something was shorting on the 5v rail which affected the 3.3v rail as well. Once i removed the faulty chip the 5v / 3.3v chip did not heat up and 5v and 3.3v was present. On gaming laptops these things are common because people use it for extreme performance.
I have this exact issue. Do you remember which chip you had to remove?
Thanks
I come for the repairs and comedy…..but I stay for the life lessons.
8:35 - An angel's face ❤️
I can`t believe you made the same mistake like me by shortig the 19v with 5v :)) So i had the same problem and in my case the IT8225VG-128 was causing it .
Whats up ! bro, are you ok? Here in Brazil everything is fine, thank God!
Here on my bench I always start like this also in this sequence: DCjack 19volts, then I test all the mosfets on the board, then the current sensor, if everything is ok, then I will check the coils, because in it we must find the primary voltages of the 3.3v and 5v board , generated by the PWM or by the Pwm's of the board in some cases we have more than one. if the voltages do not really exist we have a short. And then I test the primary PWM of the board and see if it has 19v and 3.3v or 5v output to the coils. if nothing works, I go to the capacitors. But if I find the short, I always inject a voltage of 1v with at least 1.5 ampere. So after all that, we have a high probability of finding the problem with the board. In this case te PWM was bad!
Hi Alex short question on the TPS IC Vin was not short before you replaced it? After the chip burned Vin was short? I have a Lenovo Notebook with a similar problem on my bench although its a TPS51393RJER DC-DC Step down. Replaced the IC and it blow all tracks of Vin away. The board made me hit my head against the wall as I could not figure out the problem yet.
Wondered if the "donor" board could have been used to replace the bad one?
With some upgrading and repair of it, quite possibly there could have been a fix to this one.
Looks like Asus is showing just how badly their stuff is and maybe causing Asus sales to plummet due to seeing all the problems that come up here.
As I had said before, I have a Dell from 2017 XPS 15 9560 that stays on almost 24/7 since I bought it. It has traveled with me all over the world and only thing replaced was the power cord.
I open it occasionally and clean it keeping the fans clean and the heat sink clear of fuzz and debris.
Never a problem.
The touch screen works just as well as the first day.
I'll probably buy a new one in the next year so that I have an updated current model.
Asus keeps you in business and profitable. Of course I know that you do many other repairs of all kinds of electronics. After watching some of these HVAC repair guys shows, I can say that there is a good business in board repair from what I have seen in their line of work.
Some of those HVAC boards are complicated looking but I'm sure that it all gets down to component failure.
I even saw a car mechanic find a key fob module failure due to a water leak getting the board wet. I suppose the question is........what is more expensive, buying or repairing the old board.
With PC's being so expensive, I can see how a cheap repair is much more economical.
And with your vast experience in electronic diagnosis, you're job and business is safe from ever becoming redundant.
I suppose that the military will soon be jobbing out their B1 and B2 bomber avionic components to you as well as F-35 boards.
Is there a part 3?
i love your vids never give up,.//.,
hi alex great video as always . obviously your daughter has her mothers looks haha shes a cutie pie ....
ربنا يحفظهالك ويخليكم لبعض
Where do you get your donor boards from, i work for a good sized refurbished laptop store as the lead repair tech, i have a library of about 1000 donor laptops, but i never seem to have the right boards for the kind of board repair i have to do with the walk in repairs
Watching that chip catch fire is like slipping on a cat turd in the hallway in the middle of the night.
Awesome ✌🏻✌🏻✌🏻
Good dad..
Skip to 17:55 and enjoy 👍😁
good people
The second time of blew component in the caught on camera. Last year the resistor blown and now the IC.
