Another great episode of my favorite TV show. 😁👍 That ugly cap has been bugging me ever since 1:57 😠🔥
Yes you're right. That cap looks bad but it's testing good. I ended up changing the Mosfets again this morning along with that bad looking cap. Short was gone like before. I powered on the device and Mosfets went bad again. Laptop is going back to the customer unfixed unfortunately. .
@@NorthridgeFix Hahaha You always foolproof your videos, so i knew you did! That job was too good of a tease. You gave it your best. 👍 As Hristo Stoichkov says - "Sum tie win, sum tie lewn". 😂
@@NorthridgeFix this is VCC_CORE core line where blown resistor and capacitor you got the short. Most likely a rare event happened - cpu itself is shorted. IC is battery charge controller. And mosftest near by IC gives VIN line
Was going mention that cap amazing work as always HP should seriously offer you a consultation job to help them design better labtops you seem to always be fixing these things and would have a great many ways to help them improve this line.
@@em0_tion I miss players like Hristo Stoichkov ,,
The whole video I was looking at a cap that was bothering me and looks like it's cracked or something. It drove me nuts.
same
man.. same... i was so annoyed by it.. that capacitor is my nightmare now
I highly respect that you show no fix, it shows integrity.
@ARI GOLD EXPERIENCE but it's sad coz I have a laptop with a similar problem that, similarly, led me to a rabbit hole. I think the processor might be shut, in my case :( I had great hopes that this would give me some pointers. Nice video, tho ;)
Wish you would use spoiler alerts
@@unnamedchannel1237 Wish you would watch the video before rushing to the comments to find them 😆
Spoilers
100% 🙌. Definitely
I appreciate you uploading no fixes, helps us noobs understand the diagnostic route when dealing with tricky boards like this.
It's amazing how fast time flies when fault-finding in electronics.
When I do stuff like this it is real hard to give up, even if it is no longer cost effective to repair... I respect your ability to say "No Fix" and move on.... I need to learn from you on that I think. :)
I suffer the same
Same. But its a difference if you do it for yourself or if you need to get paid for
Must be hard to draw the line on this, so near, but (maybe)so far. This type of repair must haunt you 😂
This Circuit that blow is switching power supply. Google about it, simply 2 mosfets, 1 Coil, capacitors and driver.
This guy is just learned everything diy. He doesn't know how to properly proceed with fixing motherboards. It begins with reading the schematics to understand how the device works. It doesn't have a charging issue, he already put a fully charged battery inside from a donor laptop and proceeded to remove the ic that is responsible for charging the laptop. Big time fail.
1:57 yellow capacitor in down right looks to me like he exploded
It looks damaged but its working
I think your work is amazing. Some of the process you use today were simply not available when I went through college, and I totally respect the new advantage processes I'm learning. I think your skills are spot on, to the point, and well equipped to get it done the best way possible. If you say it's a no fix, after learning what all you go through here, I more than respect that. It's not time effective.
10:06 cap in bottom middle is fractured?
This man is not a good technician
It is, but i don’t understand why he don’t see it
This is like watching an operating room procedure performed by a skilled surgeon. Thank you for allowing us to see how it is done.
Surgeon: its not fixable. Send back to family 🤣
Why didn't you changed that cap which looks like broken. ,,,,that was also physically damaged.
1:59 bottom right corner capacitor looks literally split in half, skips it, sees tiny hole in resistor 😁
I was screaming at the screen that he completely ignored that part.
That real time resistor blowing video was killer! Love the videos brother!
This is Outstanding High Quality educational content! Thank you very much.
10:32 capacitor on bottom of frame does not look healthy?
YES ,This man is not a good technician
Brilliant video! Very good reminder that although something might be possible to fix, it isnt always economic to spend the time to do so (especially when you dont have a schematic and board view). Thank you!
Why didn't you remove the big red flag -> the capacitor that was fractured?
...because it never indicated that it was shorting? Fractured or not, it was still functional. That's the mindset you HAVE GOT TO follow if you attempted to fix a laptop and didn't have the same model to extract any components from. So let's assume you try to remove that cap anyway because you didn't like the way it looks. Great, now you gotta find out its working voltage and capacitance. With no schematics to go on about and no capacitance measuring device, good luck with that.
Yes please..why?
@@Rodox2k10 bruh, he literally had a donor board with that cap for the taking, would take 15 seconds to swap for peace of mind...
Hello Alex, I'm Caleb from Nigeria.
I discovered your channel few days ago and ever since, I've been going through the videos on your channel. You've got great technical skills to show off your ability in this field, you're good at what you do, nice work.
Needful to note, seeing all the great works here, I didn't hesitate to hit the subscribe button plus smash the like button for each an evey video I cover, seeing the quality of your works, I started smashing that like button just from the beginning of the video . You're good, pls keep doing more of this .
I'd like to know where to get circuit schematic for motherboards of different laptops, hope you wouldn't mind telling me ?
#I hope you find this comment .
If you had the circuit diagrams do you think you would have been able to fix it
Just thinking that right to repair would have made a massive difference here
Hi there , how do you know that on which side of ceramic capacitor must inject the power to find the short ? any side can we inject ?? please explain in your next video . thnx
I appreciate your honesty, big respect!!
One of your even more amazing fixes! Your thousands of hours of hard precision work really shone through
Hey, I'll allow you to take a shot at fixing any device I own before I let any other EE out there. I respect your work!!!
I really love this video because you are an honest Technician. Good job!
The problem with this HP laptops and his motherboard constructiones is, everything hangs together. The problem is; 1- I/O chip 2- after installing a new I/O chip you will se that the PCH chip is gone. Result= same, back to customer.
Are you using the new leds ring light? Maybe it's just placebo effect but image looks more clear and bright!
Hi Northridge, just checking if there is any update on your training course... I would be interested in learning from you. Great Video. Cant fix them all.
How much temperature you need to pickup and then install IC with unleaded solder?
350-380 c
Good attempt, you have to draw the line somewhere. I hope that the customer watches this video to understand that you made a genuine attempt to fix the problem.
20:54 whats wrong with mlcc on right
This tool see electonics like predator perfect work
Absolutely love your show, awesome how you show all the steps you go through and find it adorable how you call your dad "Big Boss" xD hope you and he have a good new year
Can you please let me know what is the Brand, Model of the Thermal Imaging Camera??
Flir
Keep doing the good work, fixing and helping customer's to fix their devices.
That Physically Damaged Capacitor...
You Said Very First In The Beginning...
😎
bravo for the excelent video... try on the coil that you removed to inject 3 volts 3 amps without the coil on the motherbord. with your thermal camera you will see the short circuit... becareful without the coil and inject the voltage on the side with the short circuit...
I love watching your videos. It’s like therapy plus I’m learning a lot. Thanks for the content
Big fan, love from Maldives 🇲🇻
Congratulations on such an amazing achievement, can't wait to see your channel grow even bigger.
I learned a lots n lots work ethics from this channel
Not everything is fixable and it's not healthy for the business to spend more than the adequate time needed to figure and fix the problem, there's no profit.
sir please make a video to check each component , its method of checking, as some of viewers are new in this fields ,
Yeah! free tutorials!
Don't know what's happening to me I don't usually like a video before watching it but with your videos, I always hit the like from second 1 man! Hahaha! Keep them coming, please!
What if I don’t have any donor board, where I can get the exact capacitor or MOSFET?
I love how you narrow the issue love all your videos thanks for your videos and time 😎🤓😄
Sir im a cellphone and computer technician here in the philippines and i wanna thank u for your videos i learned so much about troubleshooting, ive watched all your videos and keep uploading.
مادرت در چه حاله
Great troubleshooting! By the way, where did you got your hot tweezers and what diameter are you using on the hot air nozzel? Thank you for the sharing!
I am interested to these two questions too. Thanks!
link to amazon tools, get referral too
Respect brother. I have toiled the internet for years looking for you. It doesn’t get any better.
I am sorry that you put in all of that time and had a no fix result. I have repaired video/audio electronics for over eighteen years in my own shop and I frequently have no fix results. In order to get some money for my efforts, I charge an up-front thirty five dollars troubleshooting fee. At least I earn thirty five dollars when I cant charge the client money for a no fix situation.

i know what its like when you encounter those rabbit hole repairs and what ive realized is 99% of the time its just not worth it
wooow! what an awesome video. also you got a very good gear for identifying a cause of a problem.
I love how this guy diagonised bit by bit ,though not to full success ,but it was the best example for a leaner like me
I truly appreciate ur work...watch every single detail of ur video ....I m a learner ....n learnt so many things frm u

hi can you get me HP ELITEBOOK 840 G2 45W 19.5V 2.31A/65W 19.5V 3.33A SLIM AC ADAPTER circuit bored picture please
No fix no problem,hahah,but for us who still not as skillful as you ,no fix will haunt us in our sleep....sometimes our head and self esteem hurt so bad that we almost give up fixing thing.Usually the very next day we try fixing other device and happened just to replaced a blown fuse and it turn on,suddenly our self esteem sky rocketed again and the spirit to fix things come back again...haha talk about love and hate relationship with electronic repair
Nice work, what is the temperature of your hot air gun ? those parts come off so quickly !!
the problem is 1:58
5:45
Got a hp envy touch smart 14 inch component blow off. Below the ssd port. My technician doesn't seem to figure the part. The laptop turns on when battery is charged but doesn't charge or lit the power light when the charger is plugged
You can't win them all pal .great video love watching . Out of interest when you injected voltage in to that cap .does it matter what side of the cap ?
thank you ,thanks haha,love the honesty no fix, not economical
18:44 that blown part is bugging me, lol
Im getting a few of these hp chrome books with broken usb c ports then a shorted d- d+ usb controller is in the cpu though by the looks of it as when cpu removed the short goes :(
Ghorboone mamanet 🤨
Curious why didnt use the spare board instead of doing that work? Love the videos tho, I tinker some with electronics as a hobby, and have learned a lot from you.
I'm guessing the donor board is just a similar board not an exact type of board.
My guess was CPU was blown on donor
Dammit. I have a very similar issue with another Mainboard. 13:20 one of the gates was blown and i swapped it but there were still shorts. Right now i removed the chip labeled BQ24725 but the short is still there :(( i don't have a temperature cam.
Crazy when you see something on camera before he sees it, and it gets looked over several times. Sometimes having a second set of eyes is great!
Maybe consider livestream repairs?
Great work you do, but HP is a manufacturer that I will never buy on my life nor I recommend to anyone, along with Acer, Fujitsu, Seagate All of these aren't recommend because of the lack of durability and also too many errors on systems and software
Great job as always, I'd like to ask, what is the microscope that you are using? I have decent digital microscope but with built in screen, would like to get something decent without screen to connect to bigger4 lcd
I'm quite thankful that my HP laptop still works and performs well except for a minor battery problem that can be resolved; if I have the money to replace it.
It’s very complicated for me.because I don’t understand your prononciation. Thanks.
Galing mo sir....orso electroms lang....sana makabiaita ka sa akin bahay sir..
I think there was a small hole on the BQ715, between the B and Q.
review the video before he remove the iC power then he replace new iC but incorrect pattern
high respect to show these repairs ( fix or no fix ). Your expertise has te be paid anyway. After watching your videos, i feel more confident for my own small repair shop. Im often presented challenges. Sometimes im too afraid to even start the repair. But after watching this, even a no fix seems acceptable.
im sorry but is it only me thats screaming at the pc screen about the damaged capacitor you constantly overlook? time line 10.05, the cap next to pu3 on the board? you are even testing the caps right over the top of it!
He tested it and it was good.
@@williamk9709 my bad - muust have missed it - but ocd would have had me changing it anyway lol.
Its irritating to me these companies are not forced to release their board diagrams. So many people want to just virtue signal about caring for the planet or more likely they are ignorant to the fact these boards end up polluting landfills only because we cannot fix them. If we had a way to read what does what on these boards the likely hood, they could be repaired goes up by at least 80%! Something here needs to change, and more people need to be onboard with the right to repair!
Hi...
I want to buy the same piece BQ715/TI 531/ ATLQ
plz help...
Nice vedio and we got a lesson from it. By the way your speach is like a pilet who is going to take off or landing 😂 but nice keep it up your great work... Thank you
مجهود عظيم و رائع . شكرا يا مهندس
Failures are not less important than success. They concur to improve your job quality and experience. Bravo!!(In Italian it means "I congratulate with you"). Regards from Italy.
È capace di sostituire solo le porte usb, per il resto non è un riparatore ,si ferma davanti s piccoli problemi,come adesso per un banale corto in giro è perduto.
Non ritengo sia proprio così però fermarsi così presto significherebbe dichiarare il 90% delle riparazioni no fix il che non renderebbe certo il suo lavoro remunerativo. Ha buona tecnica però questo si.
You murdered that 10ohms resistor! haha
It could have been the customer's laptop charger that was supplying the wrong voltage thus causing the damage😕.
omor eh i just dont have strenght to be doing all these, in as much as i enjoyed the video.
once the motherboard is bad i cant sit and be wasting my day on it, very clear, i tell the costumer to buy a new motherboard or better still add money and swap for another system. but no cap your work is amazing and those tools you uses i wish i have them.
#Greatwork😁👍 🔥
Salut! Dacă ești român, iti scriu in română cea mai probabilă cauză a arderii acelui rezistor smd.
hello why you didn't also replaced the ugly looking capacitor at the upper right corner on the screen in the minute 7:18??????? of the video
hello I have a hp mini 100e laptop, it does not have video, it charges the battery and the usb ports work the shift key does not turn on the fan does not turn on. maybe you can help me, thanks.
😆 .. experience .. should trump/override , guessimation .. l.o..l..
A+++++
Thanks for help us so much! God bless you!!!!!!!!!!
This video shows your good behaviour& honest.thank you sir.
hallooo. am oty from kenya. just asking your help on getting thermal camera. how much does it cost?
Hello, Please tell me at what temperature and what percentage of air you set the soldering station, Thank you!
I spent two weeks fixing the TV, in the end the price was such that the client gave me the TV and owes me money!!!!
What camera do you use for this task ? Is there anything below 200 € one could also use ?
Bro have one capicter Demag you don't remove this the capicter the capicter colore will be chang from other 😅
