Firstly thank you for the video. A 51 min edited video. Respect for the effort you put in, and the time that is hidden from the viewers video thanks to editing :)
Euston, we have picture! Roger that! Bravo Sorin on a very satisfying repair. Yes, you are better than Dell; better than all the rest, as Tina Turner would say! Loved it!
aaaah, Im always checking daily to see if there's new videos from sorin. I've learned so much. This is more addictive then any series on netflix :-D I do this kinda repairs also in my shop, but not on daily basis. Thanks to Sorin, I keep up to date every day, just by watching and learning. Please dont ever stop uploading new videos
I learnt how to fix the screen ghosts recently, requieres dissasembly and with alcohol wipe every sheet. It did work awesome and I saved more than 100 usd on it
I hate liquid damage faults and I hate chasing missing voltages around the board.. I feel your pain Sorin🤣🤣 Dell would never have bothered to fault find they would have replaced the mobo and sent it back.
For these Sylergy ICs, the letter after the numbers in the part number is very important. SY8288 (AWS markings), SY8288A (BDJ markings), SY8288B (BAB markings) and SY8288C (BAC markings) are not compatible with each other. Fixed vs. variable, fixed or no LDO output, different voltage, different pinout… No datasheet available for any of them so you need to refer to some schematics. The badcaps post "IC Marking Codes and Datasheets - Silergy" contains the info to identify them.
Wonderful! Thak you so much for sharing this. I work with laptops every day. I have gained a newfound confidence while im handling them after watching. I see lots of things differently because of the knowledge i have gained from them. Ill be watching many, many more!
I'm using Puppy Linux to test any computer . Using Rufus I wrote it to an 1 GB pen and use the half. I can test hard drives like cristal disk info (there is a program to do it), wifi keyboard etc booting from the pen (takes 2 minutes). No hard drives no problem test with Puppy. Puppy reads Windows drives, has a browser, files manager its a full graphics operating system.
Thats why Dell will not repair it. You have to give warranty to your repair. Looking at the other resistors and capacitors that are already eaten by the liquid damage i'm afraid to board will fail soon again. Nice repair btw.
Hello sir , I love watching your video very informative and interesting with all the humour keep it up .I have a Sony svf15 10year old touchscreen laptop i5 4gb ram 2gb nvidia 740m gc. GC is disabled in bios now (no new driver & I don't use it much ).battery is dead I use it without battery .My laptop starts and shuts immediately , I can hear hdd spin and shuts . When I connect charger it doesn't show any lights . After many attempts to start by pressing power button it starts sometimes and works perfectly . continues to work with no crashes or bsod or hang , once it is up and running it works smoothly. Now when I remove the charger and keep the laptop off for a day and try to start it the next day All the problems revert back and after like several 20-30 attempts hoping it may start or I give up and try some other day. I have good knowledge with soldering. Basic electronics schematic work . I have multimeter. I've tested many things by watching your videos . I feel it is either ram or cpu . Could you please share anything regarding this matter like guide me to what should I check? . Before changing the ram please let me know is there anything I could check or try.
From the symptoms and the progression of the diagnosis ..... I thought a track was also missing ..... at the point when the first chip was replaced. But how to diagnose that missing rack- a burnt resistor- I do no t know. That's one of Zorin's tricks: following tracks. For me, It was at the point when he first said the 3V was present but was not showing up where it should be .... because the track carrying the 3V is missing ... along the way to where it should be. But he got it right, a resistor will blow before a track is burnt usually. There were no actual burnt tracks: its narrowed down to a resistor. And Zorin got it! I am not surprised the blown resistor didn't leave a lot of black splatter .... it is only 3v after all. Unless Zorin decides to blow up a resistor using only 3volts and leaving a big black mark. **C'mon Zorin, blow up some resistors.**
Amuses me that he's amazed at fault finding that takes more than an hour, while I have a pile of computers and phones that stopped working with all my data on, years ago, and still hope to sort them out one day! :}
judging by all those dis coloured caps, it looks like it was left outside and condensation covered all the components and then it was powered on. this would explain the strange discoloration of the SMD components. Must be the case since it was sent to Dell for warranty which means the discolouring was not due to old age components.
Hi Sorin, very hard but very good job, can i advice with humility... i have a lots to learn from you.... with liquid demage best before start working to reflow the area with flux to prevent losing component and restore corroded welds, then clean the area... I buy Microcare Trigger Gripy to try it, normally use isopropilic alcool o 2-propanolo CH3CH(OH)CH3 but find more effective Ethanol (or ethyl alcohol) CH3CH2OH also in ultrasonic cleaner, but finally i wash also with normal hot water at 90° and hand soap.... What your way?... can you suggest the price for each work and last but more important thanks very very much for sharing your experience... waiting your replay for everyone..bye Francesco Timpano from Florence Italy 😊
Seems you got no experience. First check for short on the power rails and check the mosfets startimg with the incoming power. You did desolder all stuff because you started from the last strep instead from the beginning.
so the 3.3v chip was ok, just missing ref voltage because of faulty resistor? the 5v chip producing 5.3 was burnt so replaced. a memory slot was damaged mybe due to liquid damage. is that a fair summary of the repair, as i got a bit lost from all the chip replacements? thanks for great repair to a difficult fix.
Such a generous guy, FREE knowledge people FREE fu**in knowledge, maximum respect
Nothing's free in this world. You must understand. But Mr. Sorin work is really appreciate it.
@@emanuelguadamuz3738 I paid nothing in exchange for this informative video, like NOTHING
That's it, only a very few videos are in his subscription! All others are free which only SORIN will do!🙏👍👌

Firstly thank you for the video. A 51 min edited video. Respect for the effort you put in, and the time that is hidden from the viewers video thanks to editing :)
This vid was EPIC, twist, turns, ups and downs, schematics, no schematics, and full of knowledge....thank you Sorin for the lesson💥💯
Great fix Sorin. More twists and turns than a movie 😂
This was a next level repair with schematics needed, props for getting it working again!
Euston, we have picture! Roger that! Bravo Sorin on a very satisfying repair. Yes, you are better than Dell; better than all the rest, as Tina Turner would say! Loved it!
Very nice display of both patience and knowledge, thanks for your display of schematic reading! You are by far one of the best youtubers we have.
A long but beautiful success! "We Have Picture"
Bravo Master Sorin you are the golden guaranty.
You can put a brass brush on the probe of the DMM and brush the MB to quickly find where the 3.3V goes.
really appreciate your effort to find missing 3,3 v and finally we got the picture. Greeting from Indonesia master sorin👍🏻

I am so happy we fixed it
I love the difficult jobs the most. I learn the most. Thanks!
You correctly found the faulty chip early on, but the faulty resistor! Last thing to even believe! YOU ARE professional indeed. Thanks 🙏
My admiration and respect. I would have giving up long ago on that board. We need people like you in the governments replacing the faulty members!

Yeah well! Congratulations Sorin, you won it with your thumbs up!! And thank you very much for all your sharing
Hi Sorin better use IR Termo Camera LIGHT to check where is resistance of motherboard much easier to handle Regards Igor Mk
Another great job. Thank's for the lession!

Great repair at the end watching the amps go up and down I was as caught up as others during a penalty shootout😂

Nice repair btw.
That was a tough one, nice job. Boy do I have alot to learn.
Great job and a great video. Thanks. Complaining it took 2 hours. it would've taken me 2 years to figure that one out.
It will take me 3years to fix that… cos mind can’t go there anymore
u makes work look easy ,maximun respect
Great repair as always, thanks for all you do Sorin....
Sorin is the best love from India...❤❤❤
Amazing repair. So fun to watch! Thank you!
Congrats, I was cheering for you. 👏👏👏
Great Lesson! Congratulation Master!
wow cant believe its working :) what a nice repair sir good job as always
I have the same model. This video gave me some knowledge & I'm scared now 😅
it is good he share it with people
I always feel like we are on long road trip, when we finally reach our destination.."We have Picture!". I need a "We Have PICTURE!" shirt😁
Interesting. Looks like time to inject voltage and use the Themo Camera
aaah, we fixed it!
thank you sorin

Good job Sorin well found
A1 Sorin, unreal at that resistor, thank,s, @ 38:50
Thanx Sorin for the knowledge.
Very nice job!!!! Never give up!👏🏻
This film could be Oscar's candidate 😊 ❤
we have picture. well done sorin.
Thanks very much sorin. This is what i want to learn. Nice troubleshoot. 🙏🙏🙏
A master's job well done Sorin!
Well done Sorin
I think cleaning water damage before any check helps alot, maybe solve a problem like i had, maybe there partial short circuit.
It was already cleaned before, and if you clean before investigating you erase a lot of hints.
You have a picture before...
what a patience lar... i would crash it out just seconds before the final expand
Waiting for the last word, we have a picture of this word and the reaction makes me laugh a lot.at 46:40 Thank you, Sorin

Great job finding the failure resistor.
Yeah.. you are better than dell ❤.
nice job Sorin
Good job mate 👍
We have a picture😅😅😅bravo sorin

Nice vid am learning can you list some of the best sites where get you schematic and where you get original parts to buy plz an thanks
thank you done my job
atleast its done an lov da long vids, more long ones please
Good job
Beauty! Nice work!
It's a great fix...!!!
Thanks!
Seems you got no experience.

You did desolder all stuff because you started from the last strep instead from the beginning.
Finally a long difficult job!
Positivo e Operante!
This is the hard one !!!
Nice Job, i like this kind of video.
Nice job i will put it in ultrasonic or clean it first with alcohol then proceed with repair, who knows what liquid is.😊😊😁😁
Great job crack!!! Greeting from Mexico
I can’t believe..that’s crazy

Some interesting profile pictures on these chatbot comments 😂

@@MattyEngland yes I'm inclined to agree

You are not the only one. As well there was some editing involved where I think he replaced 5V chip. That was after he replaced the resistor.
No Dogee capacitor??? 😞😞 Thank you Sorin!
what a Master!
That was a good one.
45:53 holy sounds like some machine that is eating ram memories and spitting you new ones :D hahahahahahaha
Where you buy a schematic diagram??..
Haha now to fix the charger id circuit ;)
Love To
Sorin From Bangladesh ❤❤ ❤
How i love it when you say thats crazy....we have picture..thats insane...hehe
Why you work directly on the board without cleaning first?
Because then he would not see the damaged parts properly and could overlook things.
What other faulty components can fail the CPU if they're not detected during the repair?
I think Schematics helped to uderstand the 3.3 v IC Input/output .Its hard job
You are Better than DELL .
That was like watching an action movie
Thanks Sorin🎉🎉🎉🎉😅😅
Respect !
