Hello brother check for the nand line short,sometime the pmic get hot but the short isn't theire, he get hotter because he try to provide the right voltage but the fb doesn't give him the right value back, so he continue to push
The phone was fixed. I'll post part 2 tonight. The problem was the 3v Nand line. Thank you for all who pointed this out. I overlooked it even thought I've done it on this channel many times before. First person who pointed this out was @moh ak. Thank you Moh, a long time follower of the channel and Thank You all.
@@NorthridgeFix thank you for sharing your knowledge. Respect brother
What is nand line and where is located? Hopefully we'll ll see it on the next video. If not please let us know when you make another video having the same problem on the phone like this. And im one of subscribe who now stard mobile repairing shop this month so i really want to continue learning many things from you. I follow your channel for over year.
Thank you so much @mohak & @NorthridgeFix
Had a similar issue like this where i thought i had a shorted PMU IC but on a iPhone 6, turned out to be a short on PP3V0_NAND. i would start looking around the NAND area first. This line goes exactly where the heat is coming from.
Been watching your channel for quite some time. Great videos. Just repaired my first xbox series X the other day (HDMI replacement). In the video I used your "we did an awsome job" but I also added "as Northridge fix would say". It took a fair amout of heat and time to remove the HDMI connector, was wondering if I need a better rework station (currently using a 858D).
What temp and air speed did you use?
Low melt solder also makes a huge difference in time to remove
Last one i did if I'm not mistaken, using my quick 861dw I used 470c and 110 for air speed, came off in 10-20 seconds.
Use low melt solder. northridgefix.com/product/low-melt-solder-pack-of-6-sticks/
you probably have a short on a powerline. pp1v8 or 3v0 nandline thats why the power ic gets hot. usually its not the ic but a cap

It’s interesting that asus laptop comes often to your shop. In my observation almost all asus laptop that you repaired are ROG laptops. So my question is how often do you get Zenbook and Vivobook line of laptops? I mean is it a problem with all asus laptop or just ROG laptops?
Just have to ask, i'm not the best level 3 technician but i can do the more basic repairs. I had a iPhone 6 that had a PMU getting really hot and i searched on google for a solution cause i didn't feel like PMU fail a lot. Came across a video where a guy did a repair on a 6 with the same problem, turned out it was a bad cap near the NAND that was shorted but still the PMU was generating all the heat. Could the same thing apply here?
PP3V0_NAND goes right where the heat is coming from maybe it's the same issue?
Hi Alex! I suggest you to turn off the fume extractor when you aplly atomized rosin, cause is causing a lot of turbulences to that rosin coat. I wish you all best, and thank you for all your videos!!!
I have a DELL XPS 15 9560 with Intel i7 chip and solid state memory that I bought in 2018.
It has been on and powered up almost the entire time I've had it.
Never had any problems with the computer.
Still has the original battery. (Will hold a 3 hr charge, down from the original 6 hr charge.)
I did replace the power charger last year. (Failed due to constant twisting of the cord around the charging unit)
Just wanted you to know about this particular computer and its incredible reliability.
And, its touch screen still works.
Good morning Alex ❤
That is one tight area to get that IC out. Hope the customer is up for the challenge. Would love to see that IC being removed.
I think this is one time when you just replace the motherboard but that probably loses the customers data on the flash storage, in that case they might just prefer a new phone I guess..
The same with Apple. Everytime they raise the price and customers are willing to pay, they will raise it more, because they see customers are willing to pay. As long as people are dumb enough to give them reason to raise prices, they will continue to do it. I guess Asus is buying the cheaper stuff they can get, or maybe there are engineering flaws that cause stress on some components.
Interesting video and very nice and calm explainings, i love that. Very great. Greets
❤❤😘😘
Hi I would propose just to reflow the IC where you the heat development was seen, without any attempt to remove it. As the phone have been dropped, it is possible that one or more of the solder ball connections are degraded ( in spite of the underfill). Once you reflow (heating up) the IC, the degraded solder ball connection(s) could be repaired if you are lucky. The underfill will help to keep the solder balls in place.I know it is also risky because of the many components aoround.
Informative video 👍👍👍👍
Part 2 if the customer and Alex agrees to repair
Is it just me, or do those shiny chips, and Silicon look oh so pretty.
I always puching the like button sometimes before I watch the video or after
damn my asus phone is 4+ years old..
How do you know its the chip and not a short somewhere on that line? Thanks for making all of these great videos btw, you’re really helping me to learn how to do this :)
Nvm just seen other vid
Sorry
But if a laptop fails after 6 months then you go to the place where you bought it and reclaim a new one for warranty! Why would you go to a repair shop and repair the laptop for a lot of money? 😂😂😂
Lot of lost people out there OMG 🤦♂️
I like your t-shirt!
I hate to replace underfill chips, and I never tried even a regular chip in so tight place. I will love to see how you are doing to remove it.
I am here for that smile of winning 🥳
I like your work bro .... we learn from you a lot
thank you
Surely ASUS has a guarantee on their products in the USA....... We get a 2 year guarantee in Netherlands. We had one years ago and it never gave problem.....
Awesome video. I love your problem finding techniques
If they purchased it 6 months ago it's still under warranty isn't it? Do you not have automatic 2 year warranty in the US on all electronic devices?
Tought the same
The US has no automatic warranties. It's up to the manufacturer/vendor.
@@mbrierst1 wow, I can't even think of how that would be. Just recently my bluetooth headphone stopped working on one side, the vendor just gave me the money back. I didn't even have to send the broken ones back.
@@mbrierst1 why Do people buy Electronics when they dont even have a year warranty
@@sschueller The truth is, most manufacturers/vendors do provide warranties, as customers expect them. They aren't legally required though, and sometimes they are very short. Better reputation manufacturers provide better warranties in general. Sometimes warranties are very short as well, which is something I try to keep in mind when paying the lowest price for an expensive laptop.
acer is a bad company they designed their laptop to fail so that you would have to buy a new system that's why I tell people to not buy from acer. Dell is the same way aswell...
In some Asus and MSI battery replacements, whose new battery charge correctly but laptop only works connected to AC adapter, I've found usefull a little switch on the back of the board, whose seems to "rearm". Battery instantly starts to work. Reason? I don't really know, but it worked for me several times
Good for you bro
I want to buy microscope and other think
I am from Iraq
Thank you
It is very difficult to lift the chip from that area.. 👍
Really easy with practice, you juste to go fast at 400 °c air 60
Have a like for that shirt alone...nice video too.
My Asus is 5 years old and put up with a lot of abuse and still works. However the battery charge system is broke. Seems to be a common failure.
Nice Tshirt, greetings from mexico .
Nobody is gonna talk about the shirt 😐
Lenovo is best company for laptop
Ive learned that with Asus, and Acer laptops, battery not charging after repairing a short on 19v rail usually indicates that the super I/O is damaged internally (assuming there's no damage to the battery charge IC)
The answer to the question "Why ASUS laptops are needed to be fixed too quick?" can be something like "ASUS likes Alex and wants him make money" 😜
Hi Bro! Im your new subscriber from the Philippines and i found your channel very interesting on repairing different kinds of gadget. I just wonder if you have a video on how to fix a parallel line on the laptop screens.
What is the max current during boot? I have an iphone 13 pro that starts at .1, jumps up to around .2 during apple logo, the jumps up and down to about .7, up and downto .8, up until my meter pegs out and my 1.5 A power supply cuts out. Any reply would help me know where to begin looking.
Is it that Asus laptops are generally a problem, or is it that Asus laptops tend to get bought by gamers who then overclock everything into oblivion and wonder why they don't then last? (Genuine question) Do you ever look at BIOS settings when you repair a laptop to see whether it is in standard setup or overclocked?
And thats why you.dont buy an asus laptop. Just buy a Lenovo Thinkpad and it.will.last forever.
Maybe ASUS has an built in, miss configured overclock software that destroys the components ?
I want to learn this
+1 for the t-shirt
Came in for no power.
Love your tshirt
Love the shirt!
Nice shirt!
What happened to Asus? They used to be good. Hope customer tells u to keep goin. I wanna see the repair process on that phone.
too!
Sometimes you get impression that you are asus repair representative as there are so many getting faulty. Your videos ensured me to never buy an asus laptop. Even if asus would offer me a free laptop i would not get it, because i do not want to lose my data. I've had hp laptop for 12 years now and it works perfectly, never had any problem with it.
Classic ⭐🌟
Why was to the laptops's mom giggling about damaged laptop.
Hi Alex, was the problem with the IC?
Informative video 👍👍👍👍
My iPhone 8 get very hot and does not turn on
make more iphone videos.we love them
nice Vedio ☮️👍
addicted to your videos
thanks
Love your work 🇵🇰🇵🇰🇵🇰
Awesome shirt!
this guy is good ....
Awesome ✌🏻✌🏻✌🏻
Good morning 🌞
Great shirt!
Good job mate.
You're not seeing all the black area around the ic? The small ones look like they're literally fried.
Pretty sure that's the underfill he's referring to, it's there to protect the components or to keep them stuck to the board. I think it's the same type of goop they put around CPU/GPU silicon to counteract the forces of contraction and expansion as the component heats up/cools down. I could be wrong though but just saying.
it's an underfill
👍

first view love from 🇮🇳
Its a pmic at the back of the board is cpu throwing too much heat on that area will melt the solder joints of cpu scary but i trust master alex more than my self hahahahahhahahha
The batteries don't work because there's a failsafe mechanism. You need to reprogram the chip. Even if you swap everything it won't work because the parts don't have the same ID numbers.
Good job! I know you are busy but it would be very useful if you make make a chart of devices that are sent to you for device. For example, you had 10 ROG laptop 2021 model, 8 hp, 5 etc. Then we can compare this with the market share of each brand to check if there is any pattern or it's just a matter low quality components.
