Can you believe it guys...this man gets frustrated for that motherboard was not shorted,only for to show us how to trace short circuit The best teacher ! Mad respect!
Very nice Mr Sorin. We need more people like you. Doesn't matter the price of the device. If it can be fixed, it should be fixed. Keep up the good work with the videos. Can't wait to see more.
I love you sir! i can resolve any motherboard problems now! you have impacted a lot to me sir.I'm still learning from you as always.. I'm from africa Nigeria.
he is great...i actually fixed a montior....cant believe it...I was gonna throw this flat screen 27 inch monitor in the trash...but thought ..lets have a go...and boom..a bit of sorin and now i have a fully working monitor...cant believe it.
@@NeuronalAxon on something called an inverter board..there were 4 capacitors gone..not short ...just all of them about half the capacitance they should be ..and swollen on the top..cost me about 2 pounds to get new caps..and boom i had the thing in pieces down to the led tubes..and thought its never gonna work...when i put it back together switched on and it came on immediately...
learned a lot about caps...i put in a couple that were higher voltage and it worked...key is not to use lower voltage or lower capacitance...try to get capacitance the same ..and voltage same or else higher..never lower or they will pop.
I watch your video everyday. And I have learned lot of things from you. Love to see you working... Love u Îți urmăresc zilnic videoclipul. Și am învățat multe lucruri de la tine. Îmi place să te vedem lucrând ... Iubesc
Thank you for your great videos. I like your English very much, for me it is very easy to understand. I am German and have only school English skills, but I have no problems to follow your explanations.
Hello i just wanted to let you know i had a similar problem and from my experience on the uper side lcd connector there are 3 capasitors and on top of them there is a condactive sticker-tape from the manufacture and when you try to connect the lcd to the board fpc with your finger if you dont be carefule you also press that condactive sticker to the 3 capasitors and you get a short. So if you the sticker stops touching the capasitors the short also disappear. Love the videos ! Take care.
sorin...can you try it on another iphone with a non faulty tristar/charging ic and disconnect also the battery and put it on charge..so we can see the difference....thank you so much ..another great video
hello , I would like to know how you connected the equipment to the phone when you plug the idle phone into the charger to see the carent charging in your shop ??? thank you so much for making these videos !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hi im fairly new to smd repair and i wanted to know how to you diagnose motherboards that not powering on but not reading a short? Example I have a galaxy tab 3 thats not powering on, the battery is okay when i connect the power supply (5v ,2amps) to battery connector on the board im only getting a draw of 140mil amp which keeps fluctuating. I am lost
At 23:00 when you supply 4V to to power connector, it looks like your beefy probe is touching the outer shell case of the connector socket, which is most likely grounded. So I believe you are supplying 4V to the ground, pulling over 2A and thus misleading you to thinking there is a short when you are shorting it yourself with a probe.
Super stuff Sorin , thank you so much for making these videos. What I would like to know as well is how much is it ok to ask for certain jobs. I know you are in UK so obviously the prices will be made for UK but still is there any possibility that you could share some approximate pricing for certain jobs ? I am not saying you have to share your price list but just approximately. I may start my business at some point in Eastern Europe and this would help me a lot. Thank you
Hi sorin, please explain more about short to ground and power rail on mobile board and laptop main board, pleaseee. . As you know that, these two are sooo important things. Thnx
Hi sorin, please explain more about power rail on mobile board and laptop Mainboard pleaseeee, what is the power rail, most of the time you are talk about that, but you are not explain what is the power rail. You said at 1:24:20 this dot is main power rail, but what is exactly main power rail??. Thnx
Power rail is conductor line with the same voltage. Phrase "power rail" came from electric train transport. Rail is a ground, and power rail is wire with high voltage above train. Main power rail is basic voltage from whom every other is created. 19 V for laptops, 3,7 V for phones.
Good morning Master Sorin! I bet the guys just shorted a track +v under the first layer of the pcb with a wrong long screw on those screw holes . Thats a common fault for apple devices. We must be carefully with the screws when assembling the phone together again.
Hello, thank you for your great videos. We have charging problems with lenovo Tab Model A10-70F roken USB, we have replaced the charging USB port with no problems. worked fine for one day but now tablet charges only when closed and charges too slow. We have checked USB again for broken pins but seems everything is fine, but issue still remains. I would appreciate your advice. Thank you!!!
thank you very much sir. I'm from Africa Bénin. I learned a lot from you. I have one question: I am repairing a toshiba l550. the problem with this laptop is that after the second mosfet there are no 19 volts. I made a bridge to jump the second mosfet. now all the voltage is present: 5V 3.3v . there are 3.3 v at the power button and at the bios level but the pc goes off and off. how cant i fix it?
maybe there is 19v......but it is getting shorted to ground...so it looks like zero volts.....you have a short circuit on one of the electronics that feed off the 19 volt rail test with power supply after second mosfet......AND WATCH THE VOLTAGE DROP FROM 19 VOTLS...LImit the current and then find out what is gettin ghot....
Not related to this video A question. If I have a short to ground but power supplu draws no current. And the 3volts also still existent when power on. Why am I getting a short....
Hi there is a small current through my xiaomi mi10t pro when the battery is disconnected. I connect the battery and it goes to zero. it feel like something is shorting. Do you know what it may be? I appreaciate any answers.
Thermal imaging camera is best for shorted circuits! Shorts are the best to diagnose. Open circuits are the worst because you can’t see it with a thermal camera.
Tip for iPhone repair. ..... All of the screws are the same length. Once you put them in the board. Let them drop into the hole, if they sink up to the head they are too short. If they stick out more than a mm, they are too long. All screws take as many turns to tighten up. More than three full turns and it is too long.
Can you believe it guys...this man gets frustrated for that motherboard was not shorted,only for to show us how to trace short circuit

Beautiful and basic knowledge of electrics explained simply and clearly. Ohm loves us again :-)

This is an interesting video, found the problem after checking quite a few differing things but now good. Hurrah! your the best SORIN.
You are so smart sir.... Thank you for sharing your knowledge and skills..... God Bless.....,
what about installing a potentiometer to adjust the current and/or voltage mostly current
whats that software your using for board-view and schematics and does it to samsung galaxy?
Finally Friday, yeah? Instant like team is here.
Is good.

cannot wait for the complete version on power supply......thanks for today lesson
After long time I found a great video in UA-cam thanks sir ... please make like this videos
hey there! Can you tell me what do you use by charging phones to messure if its charging well ?
Regards from Brazil!
Hi sorrin. What software are you using
hello, does the digital multimeter have diode mode like yours?
Regards from Guatemala Sorin i Saw the Whole Video
Diode mode is a constant current about 1ma
May i know the software your using?
Nice work. Where can i get the software you use?

A question. If I have a short to ground but power supplu draws no current. And the 3volts also still existent when power on. Why am I getting a short....
Is it 68kohm or actually 86kohm that you meant to write down ?
Sorin I have a iPhone 7 plus that's not charging when on.. only when off any idea
Hello Sorin!!! Come to Besiktas and it's really bad luck :D
when you replace the chargeing ic please do a video.
Nice 🍿 movie
I am curious about the power supply update
Love too watch the videos and thank you
this is incredibly amazing
You are professional clever smart 👍👍👍😍🌹i like your explanation 👍 thank you
