It's an honest person who admits their mistakes so thank you. Many of us look up to you for electronics and life advice and this shows exactly why. Thank you for all that you do, Sorin.
I'm in my 40s, and I learned that it's not a mistake of you learn something from it. Thanks for posting this, smart people learn from the mistakes of others.
hello mr sorin.thanks for all your electronic lessons.i'm learning a lot with you. since 2020 i started following you like a beginner.but now i'm like a professionnal.you're the best repairing teacher on RUclips. i'm from a little french country in africa called "TOGO"🇹🇬thanks a lot.
This is the story of my life Sorin. You made a mistake this time... but I make the same mistakes in life, multiple times. I try to laugh at my own stupidity and for me it's just a hobby, I only work with other peoples (or my own) discarded equipment. No great loss except for the amount of useless appliances I have around the place. Even with your extensive skill and experience, these things happen.
Love! We are stupid as we take a device that is too dead to be repaired and then we have plenty things around not working, sometimes that's how we have dozen computers half working, because we had chance, other taking place for nothing😭😭😭
Sir Sorin, there's always something new to learn from you. Your supposed mistake has taught me the best line of action to take when dealing with this kind of problem. You actually wanted to show us the mistake so we can learn from it. Thank you Sir
Hi Sorin, use a blade as a chisel to cut the chip legs near the chip body, and then drag solder with the iron. Love your videos, greetings from Portugal 🇵🇹
I learnt a long time ago, when a fuse is blown, FIRST CHECK WHAT MADE THE FUSE BLOW UP. An IO chip, is in the same category, check what made it blow up.
Your mistakes Sorin help us enormously in learning and understanding electronics in general and repairing laptops in particular. Thank you so much for posting this invaluable lesson!
Thanks master your efforts always appreciated one mistake does not change the respect you deserve it's not even a mistake it just happens to everyone, you tried to help the customer by giving it a try but he gambled as you said at the start what more can you do.
Sorin, Thank you for your generous e-learning for me every week, learn a lot.. thanks .May my God bless you,your family, and business 🙏 🙌 ❤️ Papua New Guinea 🇵🇬
I know this pain very well 😬 but thanks for being honest and still uploading even failed repairs, for others to know what to watch for when doing this kinds of repair. I have got lenovo board with fried ldo, waiting for replacement chip,this reminded me to check everything connected to 3.3 and 5v.
We all make mistakes, it comes with the territory. I used to beat myself up when it happened almost to the point of feeling incapable or stupid, like maybe I should not be doing repairs, especially when I thought about the waste of time and money coming from my pocket instead it going into it. But as you've said before, we are always learning and sometimes that comes best from making mistakes like this. Customers probably won't understand the hazards of this occupation but those of us who do repair work do. Knowledge & experience go hand in hand but we are all human & humans make mistakes no matter how good you are. Thank you for showing those of us who are less experienced than you that it is part of the trade. Ever 'accidentally' crack a panel on a $1500 TV?😖🤬 Sometimes learning can be expensive.🥺
I am happy for this mistake 😂 because we learned 3 times more than what we learn from success. I am new to your channel. Thank you for your teaching. 😊
Thanks a lot for the video Sorin! Another amazing video which we can learn something. I always appreciate that you are not hiding something from us. Each repair is unique and we are learning a lot from you and you are the person who inspire me for electronics too and i'm repairing devices now at home for others. All the new Laptops which coming for repair most likely have PCH problem. It's really strange, before it was first or second mosfet :) Cheers
I think that desision is very good. I have never seen you check coil impedances in your videos. That was big curiosity for me because you always supply power from dc power supply and check the condition. I think that was wrong. Because if there was is a problem in motherboard, charger will cutoff. But dc power supply will not cuttoff and power go through the circuit and then it may be damage to components. As i think 😊. Please explain am i correct???
I'll tell the truth, I'm not sorry that you make mistakes because that's how I learn the most😊 Of course, it's all with great appreciation and many thanks for everything, even though it's better to buy you a cup than to just say thank you very much😉
Aahhh I think I understand now lol. You meant checking the circuit from the coil to pch lol. Sry. But honestly I learn more from your mistakes than mine lol. At least you have the wisdom to understand why lol. Ty for your pain and suffering it inspires us all.
Since the 386 motherboards, the chipsets have spare connections, and can be optionally soldered directly, with resistors or capacitors. The connections lead to ground, or to other chips. It seems to be setting connections, but there is no information what to do with them. These options are also in phones, and other devices.
I fixed the same model one week ago with coffee damage on the ec area and missing ram 2.5V LDO. Then spent over 6 hours removing the keyboard parts and cleaning them...
Presumptions often lead to mistakes, and the more we become familiar with particular items, the more likely we are to think we know where the problems are. Someone without experience of these circuits would have to work from basics, and not have this problem. Experience is usually helpful, but sometimes reminds us not to take thing for granted...
correct me if im wrong but normally if a chip is blown up it's caused by short circuit or something, so if you gonna change that chip you need to check what was the cause or the new chip will blow too.
that is true but the short can happen inside the chip because it has many components inside much like the thins outside so the chip itself might be shorted to ground and the current has to go somewhere or blow the chip and we've seen many damaged chips that are the only problem.
@@winlose3073 but it won't stop you from checking if there is an issue somewhere elese cause if that chip is expensive and you just solder it without checking it will be costy
Their is no mistake there, because even if he changed the graphic card chip, the mother board won't power on due to the exploded IOC and Spider IC They must be replaced too I'm a hardware engineer too!
@Electronics Repair School hi, are you using any anti static equipment? Im new to disassembling and im quite afraid to open the laptop and cause a short, i know we must disconnect the battery first and then do whatever you want but i just want to replace my thermal paste in my legion 5 15ahch model
Sorin What was you thinking? Normally you always check the coils. And the video is editing so I thought you did check. You are making a mistake and that’s because you are human. And that’s normal. I still like to see your work it’s so much to learn and we learned it the hard way this time
Still haven't figured out how to do chips like this without the solder shorting pins. I've tried low melt paste with hot air. an iron with a tiny tip and no matter what there's always a short between at least two pins. Trying to fix it always ends up just moving the problem to other pins until I have a mess.
We learn a life long.... and yeah, also from our mistakes. At least, remove back the new IO chip and the new power mosfet IC you soldered to it😉 maybe the next repair need any from it
If you insulate plastic with tinfoil, it works surprisingly well at protecting stuff, not 100% though so still try to aim away but I find it's better than kapton.
Sorin if the I/o chip is shorted and that other chip , won’t the the coil be in short as well. So either diagnostic path you would have taken would of resulted in the replacement of both Chips anyways. So how is this your fault. ? Or am I wrong.
Well actually i know what your mistake exactly is and I've been experienced these kind of fault. Unfortunately most of the 3.3v and 5 v alw ic are faulty and when you replace this ic , it will blow one of the high side mosfet especially high side mosfet of 3.3 vlaw and it will let enter the 19 v main power rail to 3.3 vlaw power line and it will blow up the ec chip and pch. You must disconnect the jumper output of 3.3 and 5 vlaw to prevent entering the 19 v to output and if these 3.3 and 5 vlaw were present , you would be allowed to reconnect the jumpers which i mentioned before.
Of course you can change the PCH, get yourself a zhuomao and buy a PCH from a reputable distributor, make sure it's new, as they sometimes come with interenal fuses set by the motherboard for the damn bootguard, I do it all the time, please change the solder balls for leaded ones to reduce soldering temperature and thus the risk of damaging it
" interenal fuses set by the motherboard for the damn bootguard" more info on that? It's rare that I have to replac the pch 8mostly because it's an integrated pch and not worth replacing or everything is damaged and I don't take too much laptops for repair). You can't really get new chips, SUHMS is not that bad on ali, but most of them will sell you something and they don't even know where it's coming from.
@MrEmiriv Also "zhuomao" is really a "Rossmann viewer" brand, noone actually uses their mechines, Scotle, Honton and now LY are the known cheap brands, do you actually use a zhuomao/seamark station? (And with enough experience you can change these with a preheater and a good quality hot air, but a lower hot air helps to make the reflow profile shorter.)
@@pp3v42_g3h I do have access to a zhuomao, it was bought about a decade ago in the Age of Reballing, difficult to justify nowadays. I did buy actually new PCHs a couple of times, and also used ones, the thing about boot guard is that not all brands and models have it activated, I heard some Dell do, in that case they RUIN the PCH, so that if you put them on another machine it keeps shutting off 30 MINUTES after turning on, not even a clean ME can save you, only a new (or otherwise unfused) PCH. I'm from Argentina where it's always worth changing the PCH and even the CPU if you can get your hands on a working one, all the way back to sandy bridge even
your “mistake” doesn’t even register with me, Sorin. but i love to learn typical failure modes from your repairs. you don’t use schematics, which would be my starting point, just physical inspection in homing in on your repairs. (mybe schematics aren’t even available anyway.) what would help me is if you could use TEXT OVERLAYS on video, to define what exact chip you are talking about…”io, bios” or whatever. thanks
Charge 75€ for the diagnosis. Checking what the issue is, is part of work. Otherwise if its that easy customer could do it themselves. But obviously they cant….
When failed repair do you pull out the chips that you replace coz it cost money. Many repair shop used to charge repair attempt fee, what do you think about that? Personally i think it fair to charge repair attempt fee cost it takes time to diagnose and time is money lol
You can desolder both chips you fitted, no point them being there and hope you will use those again so money is not a problem really. The time though... This is something you wont get back. Only way is to start charging flat bench fee for repair attempts
Get a piece of paper and trace the damage and make a map key so you don’t forget as well as notice other attached items that could of been damaged I like repairs to last, don’t yall
Learning from mistakes!🙏💚🧡I would have do the same, because you taught Us, first MOSFET, liquid damage and blown chip evidences, last day, I find a used computer for no money, And I opened it, a nice Toshiba, but not working, and liquid damage, around the screen connector, with components blown so first the idea is to search some components and change them. Yes should first see if there's current on non blown chips. Our eye is looking first to visible damage.😵
"Mistakes"??? YOU?? Ok, maybe you're old and shaky and nervous and take drugs and drink a lot. JUST KIDDING!!!!!!!!!!! YOU are the BEST SIR!!!!!!!!! WE learn, even from your mistakes.
Dont beat yourself up. As the new power supply chip did not blow up again. I think the power supply chip failed first, which then over-volted the PCH and EC chip. Any other scenario would have caused the new replacement power chip chip to fail again surely.
Phone repairs kinda suck, customers always want their phones back ASAP giving you very limited time to look at them. Not to mention how difficult they are getting to repair. If you charge enough money its worth it.

Try using low melt solder and flood the chip with soldering iron then use your hot air to remove it quickly
Cut pins with a knife, remove chip, desolder pins with soldering iron.

I've tried low melt paste with hot air. an iron with a tiny tip and no matter what there's always a short between at least two pins.

not sure if you're using flux, but flux cured the problem for me when I was learning
Flux and when everything is soldered move the bridge to an edge and use solder wick.
We learn a life long.... and yeah, also from our mistakes. At least, remove back the new IO chip and the new power mosfet IC you soldered to it😉 maybe the next repair need any from it

Dear sorin, pls tell me how I decided what wire can I use as a proper calibrated fuse

Well actually i know what your mistake exactly is and I've been experienced these kind of fault.
