I just can't stop watching your videos
One of the greatest channel discoveries this year for me.
Thank you Sorin. :)
Sir, You are the best of the best in electronic repair. I've been following your videos for the last 3 months and now I became a fan of you. I've learnt a lot from your videos. Keep posting it..
You are now a professional magician Sorin. Nice quick fix!
You have miracle hands - amazing
I love this video ...... I just can't stop watching your videos
Bidemi Folaranmi x I m feed up with adds
The word is spreading Sorin, congratulations on reaching 3, 000 subscribers
wow! jumped 22.000 in eight months
76k now
204k now
best video ever! Magic is everywhere sometimes you just have to see it to believe it. It is a sum of honest effort with some special "air conditions"... who knows? Pay for magic! Many tks my friend!
Congratulations on 3k subscribers!!!!
Thank you!
Thank you for sharing your knowledge. great videos
Now I know where the phrase "Where are my mosfets?" on that T-Shirt came from. This video was a ride full of laughs, thanks Sorin
Thanks Alot man for this helpful and educational video. This is what we really call a Repair School.
thank u sorin, nice to watch you :)
Thanks 😊 God blessing you
14:46 My bet is that the MOSFET could have a floating gate (bad connection, dry joint, maybe some broken path on the PCB) and when it caught some static charge from its surroundings, it latched up. Then, when you started connecting the power supply, you discharged it, so it opened again.
I once had a similar issue with a LED diode. I bought a couple hundreds of LEDs in bulk from China, and when I tested them, some of them were not glowing. But, since they seemed to be broken anyway, I tried to do some evil experiments on them and see how much voltage they can bear, so I increased the voltage to 5 V, and when I touched the LED for a split second, it lighted up. So I lowered the voltage back to normal, and tried that same LED again, and it is now working fine :P Looks like it needed some "waking up" :q
Speaking of magic, though: the weirdest thing that once happened to me was when I accidentally unplugged the ground from a working circuit instead of some other signal input, and to my surprise, it was still working fine! :q As if it didn't care about the ground being connected to the powering pin anyway :P I couldn't believe what I see, and tried to find some explanation. The one I come up with was that other connections in the circuit were still working relative to that same ground, so as long as all the voltages and charges on the pins stayed the same, it was like if there were a "virtual ground" in there, or as if the circuit could "deduce" what voltage it is working relative to. And as long as we don't need that much of a charge to open/close a MOSFET, it could work without the current to/from the ground. But I have no idea how can I prove this theory.
You are the best. Thanks you to share this magic job !!
If you look at @14:04, which is just after you had applied power from your bench supply to the current sense resistor, there's a mark on the resistor that looks like a burn mark - it's possible that your power supply blew a fault away very quickly, which enabled the laptop to function properly again...
Nice video, waiting the other one. Thank you.
That Mosfet decided to have a deep Sleep...lol
In this sort of situation would it be possible to measure the voltage on the mosfets gate to see if it is being switched on by the control chip or not?
I was wondering if something has happened which caused the power control chip to cut the power to protect the circuit but then for some reason the control chip did not reset so the mosfet is turned off all the time, when you forced the power through this then resulted in the power control chip enabling power again???
you can , but its a little bit more complicated as the mosfet can be channel n or p and you must find out what it is first :)
The laptop turned on after injecting 19v directly into the current sensor before shorting the mosfet that's different from another repair where you shorted the mosfet first, magic volts this time :)
Very nice and interesting information! :)
Now i believe in magic LOL. Quick question.. or maybe you can make a short video about it. What do you think about ESD safe tools like nitrile gloves, esd safe tweezers, esd mats, handwrist etc... is it really that important or just a waste of money for laptop, mobile repairs and such. would really like to know your point of view since you don't use any of it...
waste of money if the humidity its over 40%
Electronics repair school thanks Sorin.
Electronics repair school Hey you reference the "startup chip" what ic do you mean? Not bios correct? It looks like southbridge chip? If so how do you know what pin to check for voltage and what rail would it use the 3.3v or 19v? Love your vids keep it up!
Magic that doesn't require a magic wand. Nice!
Great job😁😁😁
sir you are the best
that's really magic
You can give link for clener bord and name of alcohol to fo your fulx, thanks for all video
mosfet switching ic dont work properly because of pulsation in 19v line. My gues bad output capacitors in power suply. Always check p.s. with osciloscope.
all good, thank you ...
hello sir... I have a Sony Vaio VPCSA got overheated and then shutdown and since then it doesn't power on... no power no LED indicators...nothing! I did discharge the current from motherboard but nothing happened!
what could have happened? please help me and if you have any suggestion what should I do?
thank you very much
I think the magic was in shorting the mosfet which discharged the static electricity from it
Respect din State.
Magic Sorin :D
Excellent video content! Apologies for the intrusion, I am interested in your thoughts. Have you heard the talk about - Saankramer Electronic Magazine System (Have a quick look on google cant remember the place now)? It is a smashing one of a kind guide for learning how to repair electronic items like a wizard minus the headache. Ive heard some unbelievable things about it and my friend at very last got great success with it.
Learning and practice it's the best way :)
I BEEN WORKING ON MY ALIENWARE 17 MOTHERBOARD LA-9331P WHICH IS COMPLETELY DEAD AND WHEN I PLUG MY ADAPTER I GET MY 19V ON MY 4 MOSFETS AND WHEN I GO TO CHECK THE BATTERY, IS CHARGING AT 19V BUT NO LED IS ON AND ALSO DOES NOT TURN ON, THEN I WENT TO CHECK MY POWER BUTTON AND I GET THE 3V BUT WHEN I PRESS IT DOES NOT TURN ON. ANY ADVISE FOR ME PLEASE.
Regzastar check for 3.3v on your startup chip
haha, same problem with my sony vaio model vpcs11fm. total junk. I found a broken solder, gonna try to resolder it. Try to look for any fractured solder points, try replacing the glue for the graphics card, good luck
i like it too much.........thank u....
Cold solder joint.
I thought you might have replaced the mosfet in case it goes again////
FOR MAGIC!!!!!! that's my new hashtag.
Made me laugh, what tell customer, it's magic lol
Thinking of how much you would have charged customer for this type of repair.
How to get my laptop featured? :)) I do need a good electronist, any way to contact you?
Previously I don’t believe in magic
But know I do
Hello the integrated graphic card of my Sonny Vaio SVE171C11M died is there any other main board that i can use to replace the one that i have?because nobody else have this laptop in my country...thanks:(
try replacing it. if im not mistaken the graphic card is heald with glue
my vaio does not even turn on lmfao
Hi i have sony vaio core i5 E series model: sve15136cab, my laptop doesnt take load...it restarts frequently without reaching login..what is this problem and how to resolve it?
What's the model
Who else thinks I broke not long after he put the Apple sticker on it
You God Man and Funny
nice magic.
no ones talking about that theres a apple logo on it lol
also fix can reseat cmos right?
frozen MOSFET
lol Sorin is funny, well i don't care what did you do to my laptop, its working i will pay for it, i don't give a damn even if you freeze it lol
most sony vaio's fail from mainboard or graphics chip faults. waste your time repairing it to fail again. these laptops fail quickly when pushed to their processing limit.
😂😂 you are so funny!
No wonder it's broke he put an apple sticker on it
dry joint
no way, also are 3 pins on the output of that mosfet
majic boy
FOR MAGIC HAHAHA
There is probably macOS on the hard drive hence the Apple drive sticker
Weird %)
i want my windows xp back its motherboard fried up
I have now seen enough to be able to say: VAIOs are a nightmare in pretty much every aspect. Good riddance.
until it works. then it is a dream.
until it dies again. by the way nightmare is a type of dream.
oh yes they are. Mine broke after 2 years, just found this broken solder, idk if it was broken before, but touched it and just broke off. Sony did not seem to care about how long these things can last. Doubtful about it working even after i resolder the piece in(called PD42, responsible for power to system)(if anyone can find a new pd42 for model vpcs111fm, that would be help:)
oh, and its not like i am dropping it or anything. that was my parents device, they treated it good. Hell im typing on an acer aspire one from 2008 and guess what it still works. this stupid vaio cant even turn on. And also the cable that goes to the screen, thats ruptured real bad. I will accept any help for whats wrong with it. tried bios reset, battery removal, gonna try to solder broken PD42. plz help :)
magic hahaha
Sir,,,,,
lenovo 3000 G430 Laptop on But Black Display and flash light ,, one time ... flap Display and open to flash light ,,,please solution
Good job mikroskop foto send me
I will say we did most of work in this laptop so please pay for that
why
You get what you pay for 😁
Sorin u tell eveyone dont pay for school learn from practice but you have so many Ads on ur channel.Hypocrite?
