The moment of joy when you fix the device is a unique feeling that just a repair man can undrestand.
I got shocked and supprised and felt like a real goal scored by sorin 31:18 when I heard "we have the charging light, that's insane.." like the surgery was successful.
next time you should waste an extra one minute to wick the pads on the board, and replace with low melt solder, you will even be able to lower the temperature to solder back!!
You read my mind when you pulled that chip again to check it. You videos are among my favorite because you keep it real Sorin. People need to see reality, and they get that with your channel. Sometimes things don't go as expected. We are imperfect, and we can make mistakes. But we can sometimes recovery from our mistakes and still get satisfaction for job well done!
Your passion is a example for many
Fun fact, I was watching this video from a UX363 that came in for repair for the exactly same fault. Fortunately, it was only a charger issue and anyway it is under warranty, but it was nice seeing your video.
Well done Sorin, good to see you still get excited after a successfull repair! Keep on doing what you do, we learn a lot from you. Greetings from South-Africa.
Don't worry Sorin my eyes were shut. But be sure to clean the pads next time and add new solder before reflowing the chip.Btw. congrats, nice repair.
Sorin…apply fresh Solder…I can’t believe! 👌
wow sorin ive never seen you so happy at a repair im so pleased for you and the customer ..
I'm glad to see that my suggestion of buying a chip from a legitimate seller worked
Sorin, if the Asus laptop motherboard is similar to their desktop motherboards, after changing any components, the bios does an updating and training routine that takes a couple of minutes to complete. Thus the long black screen and update time.
Also, the LED keyboard is programmable for visual effects.

It's all right, i didn't see nothing, my eyes close while watching this video. Good job.
Another successful repair, I'm glad to see that you decided to order on Mouser. I hope the customer is also satisfied and will pay for the repair costs
You never cease to amaze me and make me laugh.
31:19 I almost fell off the chair! Absolute silence and then... kkkkkkk
Excitement just like a kid that discovered a new candy! Keep it going, Sorin!
Great success! Wonderful video! Thanks, Sorin!
Sorin "I can't believe" 😂😂😂
🤣🤣🤣
I can't.
"I can't believe"
-Sorin 2023
we can't believe 🤣
I will never tell anyone 🤣
Your secret is safe with me 😅. Well done it happens to all of us😊
everyone has mistakes 😌
I have a Dell XPS 13 with the same chip. And the same problem. I've ordered a replacement from mouser and will try to replace it. I'm new to hot air soldering so I'll definitely watch some tutorials first.
"Don't tell anyone, I'll never admit it" As he leaves it in the video. 🤭 Sorin, you did good, at least you had the insight to check your work before condemning it. We ALL make mistakes! 😉
Sorin, you need to clean the pads of the old solder first, prep pads with new solder before you solder the new chip in place. I have tried soldering these chips without doing this and they most times do not solder right and I only end up burning the chip trying to get it right. I never solder a QFN chip now without cleaning the pads first.
I' m also heating the pads on the motherboard at 480° for a while before placing flux and new chip .. that i will reflow at 370°...
Your works has been a great motivation to me
Just don’t know how to get those equipments your using
Cus we really need something like that in Nigeria.
Nice work sire
If you buy a chip and they are a good seller they clean it. And you have to solder the chip because there is a layer of oxidation from the cleaner. And it wil not bond with the solder. Iam happy you found it and get it working.
Ta karteczka co wypadła z torby jest bardzo ważna. To znaczy że produkt był przechowywany w odpowiednich warunkach. I teraz trzeba zobaczyć na ten tester w jakim stanie dotarł. Czyli ile wilgoci wchłonął podczas transportu. Wilgoć i wysoką temperatura nie są dobrym połączeniem. Wilgoć chce szybko wyparować i może rozwarstwiać układ.
Hola Sorin, enhorabuena por fín un chip correcto, genial trabajo eres un crack.
Sorin, this is not the first time I experienced the pins on the chip needed to be cleaned and tinned. Maybe, caused by the solder used by the manufacturer to tin the pads on the IC.
Try the TPS65988 on other unit if the TPS65988DJ does not work, no firmware required as per specs. Pre programmed with common usage scenarios
Great work Sorin...thanks for sharing the knowledge
Good job Sorin lots to learn here 👍
I believe that chip needed to get programed from bios, that's why it took so long to start the first time, and it finished the job after starting, through update
That QFN failed soldering is like how all my QFN soldering look like on the first 3 attempts, usually after I burned my hands twice getting it to position 😁
Top Man, Top Video. I'll be happy to see a detailed video, your lesson about soldering because on fast going video hard to get that
Awesome troubleshooting algorithm!
Awesome job Sorin, but you scared the crap out of me when you yelled 😅😅😅 normally i have to increase volume pretty high to hear you, and when you yelled it was then very loud and unexpected 😂😂
I can't believe my teacher Sorin 🎉🎉🎉
What was the problem with the solder when he said you can't see these things on this channel? I don't understand what exactly was wrong with it?
I believe you should clean the old solder when you take off the bad chip and reflow with new solder and then put new chip, I dont trust the solder on new chips Sorin just my opinion.
Wow, great job sorin 👍👍
Great job but I have a question why the ic is not coming with a solder on it?!
is that true, this shooting of compilation video was paused someday because you must order and wait new chip from Mouser shop?
Mr sorin I haven't seen you so excited like this congratulations 😅😅😅😅😅😅😅😅😅
Great video, like a kid on Christmas morning 🤣 Your persistence paid off. And you showed how important it is to correctly solder a component like this. 🤭 You did that on purpose didn't you? 🤫😜
the webcam light is blinking too and windows is looking for a familiar face.
If you se the datasheet you will get scared 😂😂 I love you man 😂
Great video as always 🤓
Could it be that new chips come with a protective film layer on the contacts that need to be burned or cleaned off, may explain that which we did not see 🤣
It is not that. It's due to Sorin's bad habit of reusing existing unleaded solder. The proper way to do it is adding flux to the pads, tin the pads with leaded solder and then reflow the chip in place. If you just desolder the chip and try to use the remaining solder to do the job, things like that do happen alot.
I told you to buy chips from Mouser or an authorized vendor. Especially if it's a complicated chip maybe MOSFET or capacitors have tolerance of fault of manufacture.
Good luck
1. So it seems it's not like those pesky undocummented realtek chips with "it's NDA" kind of support. TI says in the DS: "Initial device configuration is configured through a configuration bundle loaded onto the device DURING BOOT. The bundle may be loaded through I2C or SPI."
However there is some kind of firmware GUI config tool.
2. Aren't you afraid you'll melt some plastics under the board?
It almost looks like it was the chip doing the update.
You soldered the chip and it was not initiated. When the laptop started the chip called for an update and updated itself with new firmware?
@@OKuusava These new bios updates are a good thing for repair business for sure!
I am sorry for the other customer with same problem.
Good job, oldman!❤
Good afternoon. I'm based in the UK and have a similar issue with my UX363 notebook? Sometimes it works for hours on end with no issues, other times it will require a power button discharge before it turns on. Now as of yesterday (14.08.24) after 6 months of on and off use, it fails to power up at all, no power led. What do you think my options are? 🤔 Many thanks in advance!
nice video sorin as always
Thanks for another wonderful video 🎉
Congratulations! You are good!)
There is a protocol
Rule no1
Clean the area and put new solder
but i laughed when "You saw it:Datasheet you will get scared :D good lyrics -keep it up😀
Mega Sorin - i like to see your Videos - And again a Great Job - a Great Video - Super - Thx
The last one with the DJ chip problem was doing windows update too.
.
I saw nothing 🙂but a great video once more.
I have the same laptop and issue, stopped receiving power through the usbc ports. I took It to a repair shop and they told me it would need a whole new motherboard replacement. Was it just that 1 chip on the board the he replaced that was the issue?
I CAN'T BELEIVE = The magic words.
amazing i love when you say LOL :D haha . damn :( crazy with dh one both charging ports worked but with this dj one only 1 port work like with his burned one. End: wow!!!! amazing job hahahahah lets gooo ! (and chip order packing fully sealed amazing for real !)
Salute Sorin...👏
Yup that chip need firmware to run. I have read the documention on that chip. Texsas Instrumen do provide the tools to program it. The chip also support external bios chip, to store the firmware. The chip can be reprogram with any SPI/I2C programmer. The tools natively support FTDI, Aardvark and TIVA programmer.
Good job mate 👍
34:46 what is there next to camera? that flasing red dot - is it a infrared sensor?
Face recognition for Windows automatic login.
@@ablacon64 thank you
I am confused. I saw something like bad soldering but i am in Sorin channel. RUclips must be glitching.
Very good. Thank you :) !
hello sorin
if I remember the other one died on a Windows update exactly like this one
30:25 no Sorin, this time is not good. Right side, 4th pin from the top and one above right down corner.
You added new solder to the middle of the big ground pads under the chip, which was good idea, BUT if so, then during the heating, you have to press down the chip UNTIL you see the big balls of solder coming out from the edges. You pushed it down very well BUT I didn't see these balls coming out, so it means that the solder under the chip were not proper melted (solder outside the chip were melted - yes, but not under the chip on the huge ground pad) You heated it not enough time. So you soldered it but it didn't sit down to flat completely - so some pins can be unsoldered.
@Mr Guru yes. I told him many times in the past when he solder high power mosfets. Maybe it is not because of me, but now he is doing it very well - always he is pusihing it down. Here on this video he also pushed that IC down- so he understand how it needs to be done, but this time it was not enough heat.
At this moment 26:02 I looked here ...with the first DH chip, both charging ports worked 14:39 - 14:59....
Master Sorin I'm a critic of your careless soldering.... Do apply some fresh solder before putting components back. 🤐
Nice Work
Pure joy!
I have a similar laptop but in my case, the laptop turns on, but does not charge. The second USB-C port does not work either, and the laptop just turns on with the first USB-C port. Do I have to replace the same chip?
Sorin ! you need to start working with low melt solder 183c
Those chip any 3 series DJ,DH, and CE
0:08 20°C ? kinda freezing for me, its not good for my country 😂, im in tropical Country,
very very gooooood job
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Great work🎉🎉🎉
After fixing Something your smile 😃 is price less.😊
I start to check the power from the usb-c
And then I find the main and the 3.3 present
Wow ur genius 😍😍😍
I'm happy too :) thanks
The thumbnail is like the name of a Limp Bizkit album.
And the china chip was soldering properly? Maybe there was same problem like this time???
It seems like Sorin has never ordered a genuine IC from Mouser before.... LOL, as they say.
Battery was too low, that is why it was negotiating 14V only. Once it picked up, it had increase it.
However, can't believe how "ballsy" you are to desolder/solder the chip without removing the board... and with the screen closed
what he did is not very wise, one can easily damage the case or some connector or the screen.
@@orange11squares In this case the screen is quite safe because it's touch and the digitizer can take heat, but connectors or palmrest or keyboard are easily damageable indeed.
You are the Best 🥓🥓
Nice one
Thanks sorin, great video
Wow that was my first reaction when I was 100 successful on that fuse I change. Hahaha
Sorin so excited. 19v not 15.
Salut! Daca inca mai ai laptopul am nevoie de o valoare a unei rezistente. Nu gasesc schema nicaieri. Am intrebat pe discord dar nu am primit nimic. Mulțumesc!
Salut, a plecat deja. Pune un request de schema pe forum
@@electronicsrepairschool am sa... mulțumesc
27:44 what happened, I had to go to the toilet 😎
the laptop has been turned off or losing battery power during the system updates probably
The good question over here is: Why is this chip broken? Is it going to fail again?
Bad service from Asus - I18 month warrantee for a laptop isnt long enough, the EU specifies a minimum of 2 years..
Hahaha what happen Sorin. Hahaha
Now I believe there is a 1st time for everyone. Good video anyways. Dont worry about it.
Yup the problem was those twiser...
Ey I got you on video hahaha download already hahahaha
