Agree totally, great video and information. Also, he has the ability to draw a near-perfect rectangle with his off hand! 5:30. Hes just showing off now
How did he add the amps to see which component was getting hot? Did he put the ground probe on the ground pin and the plus probe on the plus pin? And to check if it was short he used any two points and if it beeped it is shorted?
I practice laptop repair but on my second laptop repair is hard because the laptop is working on battery only or charger only. When i plug the charger it's shorted on my bench power supply but when i plug unplug its works some time. You don't have video like this that's why i don't have an idea but i think it's a bad charging chip or some protection diode.
I found your channel few days ago and today I fixed my first motherboard (Asus K53SD). I found a dead mosfet using 10 euro multimeter, replaced it using simple soldering iron (I attached piece of steel wire on top of it, so I don't damage other components). You are a good teacher. Thank you. Keep it up!
I am not quite interested in electronics by the way my department is mechanical engineering. However, his approach to problems and issues in a very well professional way, his patience and no editing etc. makes me watch his videos. Thank you!
I've watched this video over and over to help me diagnose an Acer swift 3 with similar problem. Since finally getting a linear DC power supply off eBay, I also put about 2 amps of power through my board and found two resisters heating up! One with no sign of damage, and another that had scorch marks coming from it. I've replaced both using a hot air rework station and resisters from a donor board. And after a couple trials of using the hot air gun to rework the solder... I plugged it in and VOILA!!! LET THERE BE A CHARGING LIGHT, AND BOOT LIGHT!! Thank you so much sorry. Can't remember your name. But I do love your teaching style. You give hope to those who may know theyll never be smart enough to "design a car" but at least you help them change the tires if you know what I mean. Thanks again.
Yes you are good at what you do, no questions asked. After watching your videos I’m thinking about starting a repair business and channel, but I don’t want my channel to look like I’m copying your channel. I can just about guess at what you will say. JUST DO IT. Love your videos. Thanks.
Thank you very much for your repair videos. All over the world, you have taken so many youths out of the streets with your videos. Thank you Sorin (Prof.)
I'm also an electronics technician but I never get the chance to practice my profession anymore. I'm really happy to learn new tricks and tips from you.. continue with more videos as you are a big help to many technicians like me... :)
Francis Mannion really enjoying these videos...btw Francis do u know the 2 points where he touched the power supply to send the amps to heat up the capacitors? Barely seeing where he touched it...
Thank You Sir Sorin for all your instructions!! i actually managed to fix my acer laptop using your method, i didn have a multimeter nor the tools that you have just a soldering iron, i used 2 9v batteries connected to each other instead of the linear power supply that you have, i thought i didn have anything to lose anyway, to my suprised one of the chip started to heat up when i press my hand all around the motherboard, i removed that chip(i didn have a spare one) and the laptop booted!! i do not know how long it will last though, Thank You Again Sir Sorin!!
Hello, can you please elaborate a little more in how you made your linear power supply with 9v batteries? My dell charger cuts the power supply and i don't have a linear power supply either.
Thank you very much. After watching this I managed to repair my Acer Aspire 5560 which had a faulty capacitor. No power/charge LED on the laptop with or without the battery. I had 19v from the power supply but when I plugged it into the laptop the voltage dropped away quickly. Watching this video helped with the diagnostics. Thank you once again.
I loose my words when i look at your videos. You are THE BEST i ever saw. I learn so much from you. Please never stop your wonderfull videos. You are a wonderfull person. Thank`s a million times.
Probably left hand.. in the past people who where left handed where almost forced to write and use the right hand, so people like him are able to use both hands
That's awesome!! Do you mind telling me where he put the leads when he transferred the Amps to the Motherboard? He didn't say anything at all so i got lost.
@@thingshappen9199 He put the negative to a spot where a screw is. Those are all ground. He put the positive on the last FET output. I have just used the chargeport connection in my case.
@@jdgmeester Ok. So to run the current through the motherboard he place the - lead on ground and the + lead in the FET output? How did he know to run 1.5 amps?
@@thingshappen9199 to be able to dissipate enough heat to locate the issue, you need a little power. If you generate too much, you will burn stuff. You could start with 1 Amp too.
Great videos and so quick to find the faults. Thank you for posting them all. I have repaired many electronic devices but never a laptop so I'm pleased to have learned so much so quickly.
Hi, you're the best men!! I have the same problem on 3 HP laptop and have solver with you're methode for diag. Thank you're for video and continue to repair devices. :)
A very good video . like you said, problematic smd's and short circuited motherboards can happen to all computers. Keep those informative videos coming. Thanks.
Where do you put the probe to inject voltage? Also would you be able to just put the charger on just to inject voltage? Sorry I'm just a beginner and love the way you teach your videos, your very down to earth.
First time seeing you replacing a capacitor! but the replacement cap is smaller... i was thinking you where looking for a cap with the same size.. it's hard to know the value of these smd caps but surprisingly it's working
I'm seriously thinking of going back to school for this...Nice... I'm not good at math though...my dc jack broke off and I'm trying to get around putting a new one
not all about math you know :) Aptitude is key... drive and ambition to learn... keep watching videos, you will learn a lot from watching. :) Good luck in your quest.
Hi, good day, I have been following your electronics lessons all the way and I so happy to learn and understand your continual pursuit of free education. Your good heart and the willingness to teach shall be blessed by our Allah. We thank you so much for your good deeds and free learnings. Time will come that your profound efforts and hard works will not be in vain but will gain an utmost respect and inspiration from others Again, our sincerest gratitude. Maiz !!!!!

Great video. I have two questions, the first why you use petrol insted of alcahool and the second is where you were injecting the amps and what voltage. Thanks
It is simply an bench power supply, where it can regulate both voltage and current, and even if it finds a short circuit it does not trip, keeping the load active. Allowing to locate the device responsible for the current leak.
Thank you for letting me understand what is happening when it's a short to ground. What happens to my motherboard is it sparked on a post while I had it plugged in & was working on my mini pc & now it won't power on. The power supply light stays lit so I don't think it's a short to ground but maybe it is, idk?
You never fail to amaze your viewers Master Guru! You are a Cyborg Detective. A Cyborg Police - you always catch the crooked Caps : ) again, thank you for another womderful video, i hope you dont get tired making all of these informative tutorials. Its a big help for all of us idiots. 😁
Hi. Love this #. Please can you do exactly what a short is, and how to diagnose. Some ppl use diode mode red on ground, some diode mode black to ground, and some ppl use resistance mode. What exact values do we look for? Especially with smd components. Thanks
Awesome video teacher, I have the same issue with a desktop MOBO, I know is shorted, just need to find that possible capaitor causing the short. thanks tor sharing videos.
hi there, at 09:15 , you put black wire on ground and i dont know red wire where did you put it ????did you put it on transistor after second mosfet ? thnx
This is great! Thank u for this, i learn a lot on this, now im your new subscriber. I wanna be a good technician for laptop celphone and gadgets. Thank you.
I once had a window air conditioner that was tripping the breaker and did not feel like finding what component was going to ground, so I held the breaker on until I heard an explosion and then found out it was the compressor internal winding..it blew a hole in the compressor and let out all the freon but I saved tons of time troubleshooting. Same idea here..but 240v is a lot more fun.
The guy is a genius, calm and very patient. love his way of dealing with the issues , keep up the good work

thank you doctor you are the king of electronics
You're an amazing teacher Sorin, great work as always
You make it look easy. That's because you are the master in electronics. Thanks

“And we have Picture!” I love it, awesome videos.
Fantastic, simple explanation to also help teach service techs how to find shorts, Sorin!.
Awesome, keep it up!.

You sir are awesome!!! I'm completely hooked. What is the solution you are evaporating away to find the hot/shorted components?
I believe it was lighter fluid. Same stuff used in a Zippo.
