what I like most is the attitude you have: "that was not supposed to work.." :) ... "it's time to update the information I have" ... and instead of cutting the video after those "wrong" examples, or simply not uploading to YT, you share your "mistakes" with us! That's what I like in you! I appreciate your technical skill as much as your freedom. Thanks man, keep on!

In this video you teached us way more than diagnosting phones, you teached us integrity in action. I have no words to describe the respect I have for you. I will do my best to follow your example.

Very good and very enlightening, do not let us be without your videos. When I get home from work and after taking a shower is the first thing I do and see if I have videos of you in my notifications. I have been able to carry out various repairs from power supplies to laptops and televisions. At weekends as a hobby and for friends.

Best line of the whole video, "If you are precise, then you are looking more professional". How many times have you gone into a electronics shop to be quoted a range of prices because they tell you that they can't diagnose the problem without keeping your phone for a day or so. Not so with Sorin! He taught us that the more precise you can be when talking to the customer, the more professional you and your business appears to be. Great life lesson.

Sorin, thank you for the video (keep going) but i laugh when you say "this is short video" 0:06 (37:53) 👍👍👍 as your videos is long i don't care if i learn lot about it

Sorin. I've watched this video many times. It's just unfortunate you can only like it once. I've learned a lot from you videos.

You're the best electronics Technician in KZread better than my teacher Thanks

Useful video

Once again thanks. Great video as always

Amazing guy :)

we want more Sorin

Thanks very much to share your competences, it's very pleasant to listen to you.

Most have a rather different approach in the cellphone buy and cell arena here in Asia. Irregardless as to whether the unit itself powers-up or not, it is considered first to determine whether is it grounded or not. Most grounded phones (whether caused by water damage or, component or worst, design failure) do not power-up and for those that do power-up will simply destroy the battery in the long run. A simple ground test can be done by treating the unit like a capacitor ; with an ohmmeter in the x10 range, "charge" the phone by putting the + lead to the + battery connector and - lead to the - battery connector which will cause the ohmmeter needle to deflect. If in reverse-bias mode (leads are reversed) that the ohmmeter will indicate a "discharge" state then the unit is not grounded and will most likely power-up and operate normally. If it does not "discharge" (the ohmmeter needle will deflect on both states of bias and reverse-bias) then you would probably a losing investment with a value of being a paper weight. I am very sensitive with these issues since I still buy particularly old Nokia N-series phones. I also used the same ground tests on laptops and other electronic equipment; that is even before deciding to open and repair them up. It also saves time and effort avoiding those pointless arguments with some sellers who will decide to lie about their items to sell.

Absolutely Amazing My Friend Thank You So Much 😎👍

im now learning mr sorin thanks ...

You are the best man

Electronics Master! Amazing knowledge and skill Thanks for sharing

Thank you very much

I got another good tip from you.. Thanks again :)

thanks master

Very Helpfull video sir...please i am waiting for a video where you show mobile smd components and how to check them...thanks alot again.

Is ground the same as negative ? Is that what is meant by short the middle pin with ground?

Mr Sorin, you are wonderful, i love your good works. i really like you

Sorin first thing, please show us the power supply you using and how you make use of it in all your videos. That'll clear the basics right? I hope you'll do an exhaustive video about it as soon as possible. I'm waiting in the que. This is a request on behalf all your fans out there. Thank you.

There's also loads of fantastic KZread videos on how to make them from old PC power supplies, or how to assemble build cool ones from Banggood parts etc.

wow didnt know that thank you best tech

God bless you sir

this is very funny i dont understand y to short those pin and the fone works...well you have a lot of knoweledge sir and experiences....i am still learning with all your videos so thankful with this one love it

Thank you once again Sorin . You are a great teacher . :- )

Can someone answer if these phones are hooked up to the dc power supply ? What about when he uses multimeter ? Can you use multimeter on a device with no power or battery and get readings? Sorry for the questions, I’m very new to this and I just ordered a power supply and multimeter to get started

i like your long videos sorin .....please continue making such videos

pure knowledge bravo

It’s really a very useful video thank you Sorin

Ah the good trusty Nokia N73. Always worked. In the rare event it didn't you could still use it as a throwing weapon.

Buna Sorine te rog sa faci un tutorial despre alimentarea laptop cu al 3(smart) pin.

What is the title of the other videos about batteries you mentioned in this video, I could not find it. And thank you for these wonderful videos.

nice...but can you (we) try to fix the last phone which you have said its "Software" problem..maybe its hardware..maybe...just a thought ...its just got my attention on the sequence..thanks

SO excellent ;) indeed it may also work with an old camera , Great information, thank you - the small USB testers show also what goes on assuming we have the good cable. Regards

By the way, i still have that Nokia model, still working and in good shape....damn good old phones.

Thanks for sharing!

best school thank you

That wasn't supposed to work!! 😂😂😂🤣🤣🤣😆😅😅😆😁😂🤣Funny as

I am new to electronics, could I use a simple power supply cable and cut the ends to power the phone ?

We need laptop repair,it does not matter if the subject is repeated

Hello :) Thinking of wiring an old tablet on a stereo as a permanent touch screen(always on)... Would it be fine if i wire on the pins as you show testing? Thank you!

Amscope, Hakko, Amtech etc. did not sway you..... keep up the good work!

They are all good examples.

Thank you Sir. 🙏

Sorin, if we charge battery we swap VCC with ground, will the battery get exploded?

Thank you very much. It was very helpful. I have a question. There are sometimes glue under chips. How you replace chips with glue specially CPUs

many thanks, sir.

Is it not dangerous to touch the hot lead with your bare fingers like that? Or is it because the amperage is low? Or is there a built in protection from the power supply so the user cannot get shocked?

On the 5V PSU etc.? Yeah, the voltages are safely low enough so that it's not potentially harmful.

'Oh yeah, the phone it is commin on, that's weird''....nice:))))

Thanks you Sorin. Enough interesting clip. I have too an old Nokia mobile phone now. Because of its simplicity. size and purpose showed me the best. Not because of the low price (i also have two mobile phones worth 1000 euros). but I do not like android phones because of their complexity in the work. Make a clip. - that works like phone hardware

best techie ever 😊

The best men on youtube

You should be a teacher of electronics in school. One semester and we have a bunch of students with very good starting knowledge....In my high school electronics was a class just to pass it, there is no chance that somebody could explain something, even show on example. Your videos should be part of learning process in school I bet even for the teachers.

Take it to museum man

I like your watch. Is that a Timex Command?

All the Samsungs did power up with only + and -

sir, can you share about replacement EMMC smartphone ..or CPU and how to a right way replacement IC thx

Hello sir your video help me a lot. Thank you. I have a hp g62 ,when I press connect power cord it auto start cooling fan . No display , if I press power button for 10 sceond it don't turn off. Any help? Where to check ? What you think?

Hello Sorin, thank for your videos thay are really helpful. i just wanted to ask you, i have got this AT&T LG G4 H810 freezes alot then turns off even if i'm not doing anything and the display is off, BUT if i plug it into pc via usb or play a movie on it, it doesn't freeze and works just fine. i'm looking forward for your any tip would be helpful and thank you again.

What machine do you use for testing?

Hello can you test electronic like video player or video cameras by probe multimeter can you give some ideas please many thanks

How are you combining your different meter reading (usb, voltage, amp etc) on one screen? which software are you using ?Please send me link Thanks

how do we use a multimeter sir

Sorin, have you tried PC GPU card repairs? those are quite a challenge...

why don't you use crocodile clips and connected pair of red and black one with supply wires

Nokia N73 ... very good one.

First doing like button then watching video. 😎

Please note that all the phones in the video that worked with + and - only are of samsung brand. Perhaps samsung does not enforce such limitation.

brilliant !!
