I like so much your videos. May God richly bless for sharing your knowledge with us. You are so special. Don't you ever get discouraged from any nonsense from anybody.
With the USB stick: Doesn't the customer usually only care about the data on it if they bring a brocken USB stick in? I would wire a cut USB Cable to it and then either copy the data to a new stick they've to pay for or offer to send data through a file transfer service in a pw protected archive. Or give them the stick just with the cable attached
@AMECH AM Antonio Micello That case is possible. Sorin just asked in the video how others would handle it and it hink in "many" cases that would be the cheapest option if the usb connectors are not as a replacment part in stock.
@AMECH AM Antonio Micello I pay 3.1 euros+vat a 32 gb usb drive (wholesale price) ... maybe looking at this price .. destroying a new usb drive is an option...
I've used old mouse cords are any USB cord and just solder to recover when the devise was bad and only need data recovery. But I also have some of the new solder ports.
With that A70 : The A40+ series have a problem with the connector on the motherboard. The problem being when you change a battery a screen or idk you have to pull off the cable. Well at that moment you preety much brake off the connector and it will not make a good connection on the motherboard anymore. And no, resoldering won't work because the pad is comming of with the connector. It took us around 20 phones to fingure this one out. A way in wich you can test this theory is to push on the connector then connect the battery and try to power it on or charge it or watever. I changed the charging port of a police officer in my country and he was back after 2 days. I had to put a pice of plastic over the connectors to push the connector down because it only charged when it was pussed down. If you look in the troubleshooting manual the first this responsible for most of the faults on these phone is that bloody connector. Eithe the one on the mb or the one on the daughterboard ✌
hello sorin, nice workflow. happy monday... nice to see u again happy and healthy, please make a video on how to make a linear transformer.. i know your good in power supplies...
Sorin, the A70 problem is the main board connector, squeeze the left side of the connector with tweezers and it will charge, its a problem on all the A series Samsungs.
Since the old cable was to hand, I thought it would be obvious to refit that one temporarily to see if the screen worked - there would be enough power in the battery to show something, after the few minutes of charging...
Zorin, you don't need reballing station, they are useless. Buy a set of stensils and Mechanic solder paste. It's very easy to reball small chips like this. I also recommend buying stensils with square holes as the chip releases much easier from those. Cheers!
Hello sir I am very enjoying your video I have learned a lot for pc repair thanks so much now my problem I have hp compaq 6710b it was kept above 5 months now I want use it but it is too slowly I tried windows 7,8,and 10 but all is too slow even during the formatting and bootting I hope you might help me to solve the issue thanks
Another great video Sorin. Thank you! I'm very impressed with how you managed to solder that tiny BGA chip on the phone's motherboard. It is amazing to see that excess solder bubbles going out without shorting the contacts and pins below the chip. Simply unbelievable. One would expected that all if excess solder is out, there must be many short circuits below the chip. But that obviously is not the case. Is is Rosin this magic thing to make that happen?
Great as always.. thanks for best knowledge.. sir please give us some tips of mobile motherborad tracks tracing. some mobile have no diagrams so how we can trace the lines easily.... Thanks🙏🙏
Hi sorin for that Samsung a70 to confirm if it's from screen or from riben cable try old one and turn phone on that mybe give u idea a fan from Morocco i learn lot from u thx
Admirative of the repair , that old Samsung model , repairing an USB2 key : wonderful, "fast" and ecologic (cool trick to secure the port with hot melt) OH ! that Pirl charger does not offer fast charging at 9V ? Relatively useless then. I almost baught one due to the good advertizing you gave them.
When the LCD is not working, I've never seen a phone automatically connect to HDMI. As I understand it, you have to enable it, meaning you need the LCD working first to get into the settings and enable it. And there's two different standards now also, different cables. That's my understanding.
AJ PARTS UK LTD these they send all the time bad screens! We buy like 50pcs from them, (with testing service - witch was paid also) and they all came with dead pixels, and the same wire on backlight! All of them!
"...board getting hot, weird things happening, current falling..." the weird things is actually just one thing called THE ALMIGHTY RESISTANCE which increases with temperature... :)
I have done it years ago when i needed retrieve data from 8gb patriot. Soldered short usb wire and I tape it with electric tape, and its working to this day XD
My room has as many projects...its just that mine don't get fixed. Two surround amps with about 100 boards in each one has kind of stopped me in my tracks :). Maybe its because I lose my screwdrivers as well.
The beard itchiness will last max 3 weeks, for most people it's much less. You go through this only once, so if you shave off your beard, then grow it again, it won't itch. Hope you keep the beard :)
Sorin am si eu o intrebare, zimi si mie te rog ce GoPro folosesi ca si camera de filmat, ma refer la cea care iti filmeaza masa, si ce camere folosesti pentru a monitoriza display-urile multimetrului si a sursei de alimentare. Multumesc si astept un raspuns
The only thing they care about is the data on the USB thumb drive. In that case, you can just solder a regular USB cable directly to the traces. It's not easy, but I've done it before enough to get the data off.
My laptop stopped charging and a replaced its AC/DC port and battery and nope but when I connect a battery that has some juice left, even when the charger is not connected the charging led turns on 😭
On another Asus model with a similar problem when the brightness had only 2 values, 0 (black) and maximum, I put old drivers for the video card and the brightness works well. In addition, the automatic installation of new video card drivers must be blocked in windows. www.howtogeek.com/263851/how-to-prevent-windows-from-automatically-updating-specific-drivers/
Sorin, you can't find a screwdriver on your desk when you need it, because your colleagues come to your desk every time they need one, since it's SURE they'll find it. so they don't lose time.
This screen is a Next level off doggy :))))) Monday morning day every thing dead screen Samsung dead battery...... nice video movie and nice beard itchy :)))
I feel so happy to get a video from you. You are a genuinely kind person and your kindness comes through your videos. God bless you
Domnule Sorin , când vă ascult nu știu cum se face, dar prind viață.
I have to say. Love the videos. And love how you start all the videos with your signature "helllloo". Keep on
I like so much your videos. May God richly bless for sharing your knowledge with us. You are so special. Don't you ever get discouraged from any nonsense from anybody.
Thanks Sorin . Hope you and family are well .Much better watching you than TV . : - ) .
45:35 yeah place the pcb on the metal sheet to short the most pins possible, no space without conductive material around to place the opened phone
Thank you for your videos and your insight.
Glad to see you are well.
Take care and stay safe.
you're always best for repair phones please do more video ss
thanks so far
Sorin, I definitely need your patience. Well done.
The best video so far ....... reality in practice!!
very nice video . and nice job on the mini speaker . its a nice show how you fix everything with love electronic and never give up 👍

Yep... probably customer was happy to have a new usb drive with the datas... can't understand this repair...
Customer have all his data i think. And Sorin money for repair. I think is all ok.

S7 chip is ovp over voltage protection you can get solution by making a jumper .better to change if you have spare
very happy to see you sir🙏
Hi my friend here with you watching your excelent videos
Thank you for a lovely Bank Holiday treat! Best wishes.
Helllllo...it's Monday....again!😂
Great work as usual
this is a wonderful video. thanks for sharing. looking forward for more videos like this one.
well done and i just freeze when i heard Ro words in there i am too. Good job and keep going ;)
I had many A70's come in for same issue. Some have a bad connector on the board, some had to get charging ic replaced.
Yeah, A series have pretty bad charging boards and ribbon cables... Changed it many times, and it is always or board or ribbon ...
I've used old mouse cords are any USB cord and just solder to recover when the devise was bad and only need data recovery. But I also have some of the new solder ports.
this is better than any movie!
I love how you work
what a day!!!!! but thanks for the Video, regards to you and Family
I love your workflow video!
1:24:15 you have that kind of battery in you e-cigarette (vaping device), which you have in your had and smoke :D :)
Sorin on screen: 'this is next level dodginess!'... lmao...😇
Hello mr. Sorin so nice to see you are ok
I Appreciate all your Videos

4:13 thank you for that. I though that big pad it is a ground as usual. I'm suprised that this time, one big pad is plus second big is ground
That chip size is just crazy small against your finger print. Your dexterity is still way above the average human Sorin you 100% still have it lol
The beard is taking all your mental energy! xD
He advised about that ))
Man I really enjoy your videos and your repairs, keep it up👍
Most interesting not just on your work, some how repairing what appears impossible, but the other activity as well.
hello sorin, nice workflow. happy monday... nice to see u again happy and healthy, please make a video on how to make a linear transformer.. i know your good in power supplies...
37:15 I was wondering when the hot glue came out 😂😂😂😂😂
Welcome back sir
i learn lot from your videos sir
Hence the old electrical repair saying. "When in doubt, take the fingy out". Works every time.
Sorin, the A70 problem is the main board connector, squeeze the left side of the connector with tweezers and it will charge, its a problem on all the A series Samsungs.
Sorin, you can have reball kit for iphone only and use same kit for small ic. I have only for iphone reball kit.
Since the old cable was to hand, I thought it would be obvious to refit that one temporarily to see if the screen worked - there would be enough power in the battery to show something, after the few minutes of charging...
Zorin, you don't need reballing station, they are useless. Buy a set of stensils and Mechanic solder paste. It's very easy to reball small chips like this. I also recommend buying stensils with square holes as the chip releases much easier from those. Cheers!
How do you display multimeter and power supply details on screen? Separate cameras?
Cheers

on the a17 you could have used an usb c dock which has a hdmi connector and if you connect it to a second screen it will automatically cast on it.
When the LCD is not working, I've never seen a phone automatically connect to HDMI. As I understand it, you have to enable it, meaning you need the LCD working first to get into the settings and enable it.
And there's two different standards now also, different cables.
That's my understanding.
Thanks as always!
@sorin what is the model / brand for that green ammeter ? amperimetro ? link for purchase please ... thanks ... greetings from Portugal ...
finally. new upload. 😎🎉
I never see someone pushing the BGA chip down and its working properly wow 👍
Thats not the way to do it thats for sure.
Is the ST4054 chip (charging chip under the port dead) on the speaker? (looks like hole - hard to see with lighting reflections)
0:45 I have the same :) my hairs are too hard/strong
AJ PARTS UK LTD these they send all the time bad screens! We buy like 50pcs from them, (with testing service - witch was paid also) and they all came with dead pixels, and the same wire on backlight! All of them!
"...board getting hot, weird things happening, current falling..."
the weird things is actually just one thing called THE ALMIGHTY RESISTANCE which increases with temperature... :)
what about a old usb charger cable to fix the USB stick. cut it and connect it to the usb stick.
I have done it years ago when i needed retrieve data from 8gb patriot. Soldered short usb wire and I tape it with electric tape, and its working to this day XD
usb stick, cut a usb cable solider cable wires to board and "Hot Glue" back together!
But nice job as always

i hear some people say dont push the BGA chip down while you are soldering it with hot air gun but you do opposite here .. which way is true ?
i like the chats around ...i get to see the shop dynamic.. please dont shut the mic anymore :)
Married and clean shaved. That is my motto.😢😢😢😢😢
👍👍👍nice to see you😊
I sent you a silicone mat in 2018 but you used it once and never again. Oh well. xD
I still have it, thank you, one of my co worker is using it. I'm using the pad only when i fix phones.
@@electronicsrepairschool Hello Mr. Sorin , please provide your shop's address & phone contact .
Thank you
you'll get used to the itchy beard don't worry and keep it growing
the Itchy thing ----> Hair but as it grows more itching won't be as bad
oh ya try that little brush for dying your beard like Steven Seagal lol
What a hack manufacturing job on that "new" screen. wow!
Love you mate!!!)
How do you know the chip is sitting perfectly on the pins underneath the to the board?
You don't you just pray it will be or you will try again
22C ..we got 14! where is the summer?
Sorin am si eu o intrebare, zimi si mie te rog ce GoPro folosesi ca si camera de filmat, ma refer la cea care iti filmeaza masa, si ce camere folosesti pentru a monitoriza display-urile multimetrului si a sursei de alimentare. Multumesc si astept un raspuns
E un logitech brio cea ce filmeaza, restul camerelor sunt no name -uri
The only thing they care about is the data on the USB thumb drive. In that case, you can just solder a regular USB cable directly to the traces. It's not easy, but I've done it before enough to get the data off.

I hope u do more videos about phones
La mulți ani !
screen goes black when i adjust the displays brigthness below 60 dont know why its an asus A52 model . what can be done to fix this ?
On another Asus model with a similar problem when the brightness had only 2 values, 0 (black) and maximum, I put old drivers for the video card and the brightness works well. In addition, the automatic installation of new video card drivers must be blocked in windows. www.howtogeek.com/263851/how-to-prevent-windows-from-automatically-updating-specific-drivers/
Sorry but I can't understand what Sorin made on the 15.6 screen...
I guess we know who will be delivering our cringo presents next year. Board should be in place by then.
Try to scavang the port from a faulty data cable
buna, eu incarc orice tel cu incarcator de lg 5v 0,85a pt menajarea bateriei, ce parere ai ? ceasul ala albastru imi place, de unde l-ai cumparat ?
Please more work flow video
Come to Besiktas Sorin... Fans scratch your beard everyday...
I really doubt you solder that chip ok, but It is interesting to watch your moves to repair things
try the old cable maybe screen will work
On 36:05 you scared to?
Try the old ribbon cable
Salutari din Germania
Why destroy laptop battery to take one element from it? You could have taken the rechargeable li-on and solder wires on it ?
The beard will stop itching as it grows, make sure to shave your neck as that will itch like crazy. Excellent video.
Hot glue hero lol. 👍👍👏👏👍👏👍
Sorin, you can't find a screwdriver on your desk when you need it, because your colleagues come to your desk every time they need one, since it's SURE they'll find it. so they don't lose time.
This screen is a Next level off doggy :)))))
Monday morning day every thing dead screen Samsung dead battery...... nice video movie and nice beard itchy :)))
phone with no picture could be static build up disconnect battery press ower button for 15 sec to discharge static
I think I would cut a usb cable and use the conector.
workshop daily please
:))) 24:30 ...grija mare cu sucul !!! (vreo 6 cafele sunt acolo...)
Something is wrong with your solder iron
i know, i'm not happy with this brand/model
