With big mouth NorthridgeFix this board was going to the trash, there's no way he would've fixed that. You are so much better and your videos are leagues ahead in term of educational value. Keep up the good work.
So true. Sorin is a true teacher with actual knowledge of electronics. NorthridgeFix is just like any other repair person who only know what part to replace based on previous knowledge. Absolutely no electronics knowledge being used.
Keep in mind that NorthridgeFix guy can't spend this much time on this kind of diagnostic procedure, So he doesn't even bother to attempt this hard repair,
Also and most importantly, he's advertising his tools and parts, which is working great by the way
thats why he just dropped 2 Mil on a house though@@TEKMENT
as long as it glows hot on his thermal cam, nrf can fix it😂😂😂.
no way he can fix a burned mother board with shorts on the layers.all his fixes are easy and basic..
Fantastic diagnostic Sorin. Great deduction on how to repair. You are the electronics Sherlock Holmes. I like the was you never give up on a job until you can fix things.
You were on Apollo 13 with than dead mobo, Sorin. You didn't know what part went wrong and didn't have a spare anyway, but you found a way home. Kudos.
WoooooooooW Mr SORIN you ARE *THE GOAT* YOU COMPLETELY HUMILIATED THE COMPANY AND DID A BILLION TIMES MUCH BETTER JOB THAN THEIR ORIGINAL COMPONENTS (FROM NOW ON I'M GONNA CALL YOU *THE MASTER*
One of the greatest jobs I've ever seen LITERALLY
this is pro level repair, Abbott level,now i see what it means to hold thirty plus years of repair experience 👏
Franchement, chapeau bas !
The step by step approach was amazing and very consistent to reverse engineer the missing component expected behavior. It was a really strong and smashing process… my deep respect captain !
Incredible fix! This is helping me understand how the motherboard works, how each stage of power is being started. Very cool!
Hello, great video as always. I have fixed a few board with similar issues ie. (Physical damage in the same area). The reason for the damage in that area is because most cases have metal rear covers where you put in the GPU, these you have to bend back and forth to remove. The problem is that people install the motherboard before removing these and end up scraping the motherboard ones the metal tab breaks off.
What is the purpose of these metal tabs? They need to be removed first when motherboard is about to be installed in the case.
They are just there to cover the holes for PCIe- IO in the rear of the case and its cheaper to stamp them from the same piece of metal, but it means that the end user need to break them off.@@asv5769
@@asv5769 - cheap cases have them as blanking plates- avoid cheap cases
Bravo Sorin! I really enjoyed watching you troubleshoot to find out what the secret component was supposed to do. Very enlightening content, Thank you very much.
No any doubt that you spent more time in electronics and you learned electronics properly. This makes stronger than others.
Incredibly enlighting as always, a true master. Thank you Sorin
Incredible repair Sorin! Thankyou for sharing 😁
We are expecting you to do something like this.
Maybe one day! 😂😂@@4Relax
Good old fashioned logic applied to a problem. Great result, enjoyed watching.
Hi Sorin this is really a nice fix , great fault finding. Congratulations
Hello sir. I love the way you do your things. And I have. Learned alot from you. Thank. For your support
Great video Sorin 🎉 I may be young but coming from the automotive industry I completely understand your outrage.
You are very flexible Sorin. I enjoyed watching the entire video. You possess the spark of true primal knowledge.
Another incredible repair Sorin 👍
I am not into laptops repairs or desktops for that matter.
But i am waiting for these videos like it's the second comming. Great job, man.
Beautiful Work!... You, Sir have a wonderful magic bag of tricks and fixes! I applaud you! :D
great video sorin ... very interesting to watch
Mr. Sorin electronic it is flexible.. this is correct centences, thank you very much for all videos..
This guy is smart. Very well done
Hello. I like the way you do things. I got knowledge from your video. Thank you for the video you shared.🙏🙏🙏
This is a great experience and thanks for sharing it 👍
Thank you for these very informative videos... Great Job!
Pure reverse engineering! Good stuff!
Sorin you forgot to google the motherboard model and find what is missing on a picture in google 😅
unblievable repair how can anyone expect it to be a voltage regulator ?!
very smart repair.
Nothing but pure Genius!!!
Great video
Awesome video 😊
You are indeed worthy to be called a Master! 🎉
Sorin is a Wizard at this point.
Generation 2k : we need to find chip of these
Generation 80’s to 90’s: resistor is fine👌
👌
70's be like: let's use some proper calibrated wire 👌
Good job mate 👍
headsink is amazing!
Sorin, I would have follow a different path. When you saw there was a connection to at least two pins on the Nuvoton super IO. For instance, the two pins connected together with 3.3V present are connected to pin 99 VBAT and the pin with 10 Ohm is connected to pin 88 Power OK... This info are good clues to proceed troubleshooting. Nevertheless another excelent video, thank you.
great job
Sir you have many patience I must tell you . but any ways good fix although it took that long. Love your videos
I think mosfets can get some charge if you touch them or it gets to them somehow because sometimes ,and I faced this a lot on desktop boards, when the graphics or the cpu fans run at high speed I just reconnect somethings and it just works fine now I have no explanation to this weird stuff but static electricity can be wrong though.
Sorin good job, I don't understand where you soldered the output of the voltage divider, to the 3.3v pin , or 10ohms pin ? It's not clear in the picture. I see you got 3.3 from big trace and GND , but it's not clear where did you placed the output. Greetings to you and your family
Magic, Sorin magic
It's 3.3v precise voltage detector
There is a small 6 pin IC that is missing there at the upper right corner of that Nuvoton Chip. I can't make out the writing on it. Also there was one strange pin on the LGA pins for the CPU socket on the 8th row in from the bottom. My money that missing 6-pin IC probably a control IC for the Nuvoton chip. See if you can get a look at another an ASUS x670 or x670e board to identify the missing chip.
Terima kasih pak
teacher....respect
Hello🤝, I am positively shocked by this repair, I like how you approach the problem and you are wondering how it works, to fix it, I personally wouldn't apply the voltage just by eye, but it comes from your experience, thank you for sharing this experience with us, it is priceless. greetings for the whole family.👍👍👍👍👍👏👏👏👏👋👋👋👋👋 P.S. I am wondering how to select burnt SMD resistors when we do not know their value. I have a charger with 5 burnt SMD resistors, they are charred and cannot be read, and I cannot find a diagram or anything on the Internet to fix it.
you can figure it out about the resistors value by the placement on the board schematic. Yes, you don't have schematic but you can draw the schematic on your mind by looking at the board. Please post a board picture on our discord and we can find together what are those resistors
Hello🤝, I reached the value of 4 of the five resistors myself, but I still don't know the value of one, it is at the output (SF1 001 thru SF1 007) it is SUPERFAST RECOVERY RECTIFIER, after removing the burnt resistor, there was a marking L1 under it, so it should be a coil, but the component I removed is flat, and it cannot be a coil, maybe it was like that in the original design, but at the factory they wanted to save money and in my opinion they put a low value or zero ohm resistor there, because right after it there is a 60uF SMD capacitor, what do you think about it ? I'm sorry I didn't post it on Discord I didn't want to take the easy way, best regards👍👍👍👍👏👏👏👏👏👏👏👋👋👋👋👋👋
I found that the missing 6 pin chip is the same as the one just to the right of the missing one, you will see another 6 pin chip there. I think they are the same. Perhaps you could get a similar one from a donor board? you art the least try to determine what voltages and resistances the pin show and try to replicate them on the missing ones pads/traces. Good work though. Cheers!
Really genius
Excellent! and no schematics, just a bit of calibrated fuse again!
And the adjustable resistor was awsome to get the 1K right, i will be watching this one again a few times, Thanks Sorin!
sooo crazyyyyy ...I CAN'T BELIEVE IT
very good video, But a most i want to see a fixing of a broken or turned to one side pins of AM4 processorr!
Brilliant
Come to Besiktas,Sorin...
bravo
Sorin, I think maybe you are right about the missing part being a voltage regulator but not a fixed 1V regulator. The 10ohms was probably an external adjustment to set the regulator's variable output to 1V. Does that seam about right?
That is probably too new, but there are a lot of free PC MB sch/boardviews, ie, I found them for all 12 of my older MBs.
PCH PS on 4th gen MBs are 1.05V.
Sorin do you do CPU socket replacement for AMD?
I like your style. Most of the people uses water colling system with 3x120mm fans, but you :D :D :D
Ok so im assuming the pin in the upper left most corner of the mosfet was output, because he connected the resistors to it. If so, why did it have 3.3v on it before he messed with anything?
So why was the mosfet ripped from the board? was it an ebay special? It just doesn't make sense, nice to have a longer format (quite remarkable) repair, only an artist can model clay and you are an artist.
When this happens to me i search online images of the board... after a while usually i found an hi quality image.. and after reading the number of the component .. i go ahead searching more infos...
why you could not use 0.8 volt from the bios voltage ?
Is that the gpu detect circuit?
Hello Sir, I have a Dell laptop that I just got back from a local "IT Specialist" because my HDMI port stop working. He said he tried everything, the port is recognized but it won't desplay anything.
I asked him about a short and he said it couldn't be because it is being recognized with the computer.
Could you give me any tips on what else to try? Thank You.
Using the torch as heatsink was epic 😂
❤❤❤ jst great
UNBELIEVABLE ((YOU ARE AWESOME)) no no no you,re tHe *GREATEST*
Sorin, I think on that place had no chip, isnt a missing chip but the damaged tracks are dumb spot, if you observes, maybe where short circuiting the pads besides, causing some kind of protective mode, shorting 3.3v to a pad besides it, review on video. Just puting the tracks on its place should fixed the MB.
I dub three "FrankenSorin" - IT'S ALIIIVVEE!! 🤣 nice fix!
AMD boards do memory training when new ram memory is detected to determine best speeds. So first boot could take up to 5min to complete. This is normal for new AMD motherboards and CPU's
bonsoir monsieur
si vous avez fait attention au temps 13.52
je pense qu'il est le même chip .
I wonder if the customer has the tiny missing chip rattling around in the bottom of his case and not realise it- your right 30 years ago you used to get a schematic in the back of the manual when you bought a motherboard or even the old 8 and 16 bit micro's that were out before then...
Why some parts of the board and slots are covered with the metal shields?
So people will pay extra for the 'Pro' motherboard. :D
nice
Why didn't you check the datasheet of the nuvoton chip to see what's that pin does, which connects to that pad.
Because he is smart enough to figure it out on his own. That is how he and you should learn electronics repair. It is not supposed to be easy.
@@jimle22 this is not learning. What if that pin expects data bits?
I cannot believe my eyes!!! With all the experience you have in pc/laptop repairs you couldn’t see that missing component is a double n channel tranzistor. 2n7002dw!!! OMG!
tau tu kamal he yrr
You can do magic
Remember the time when you opened a radio and schematic diagram was inside...
It's that pubic hair at 1:28 lol
I already found a bent pin which you checked the cpu socket
Hey Sorin, new AMD has a built in GPU
"Okay, so this is a heatsink" :) :) :)
By symmetry I think the missing chip is same as chip next door 701k
i was thinking the same. what is 701 k chip? i dont think it is a mosfet, maybe 1v voltage referece/or LDO regulator or less likely some logic gate or flip-flop. But I don't think it is a logic gate or FF, usually in and out are at digital levels, not 1V.
this mobo has a schematic on internet.just check and get the missing component .
People are there own worst enemies. Buys the most expensive Motherboard and processor. Doesn't know how to install
Before you connect a video card and a screen, connect a keyboard and see with the lamp of the Capslook working
Sir, can I mail in my laptop for repair & will have it collected from your address via DPD
a photo of the MB could've helped
mini360 (DC-DC) output - 1V
SL71051 ??

Even if this is the correct component, where would you buy it... and for which price (part+shipping). The repair solution provided in this video seems more cost effective.
Thank you, Sorin.. Genius..Nooooooo lols, Well for the untrained its a wonder to behold. IM gona send you some titanium tweezers,
It might be an UVLO chip. 😊
I'm 99% sure that all amd 7xxx has integrated graphics, only 7500f doent I think
huh yeah desktop motherboards are much more harder to repair than normal laptop motherboards thats why i am not big fan of this new desktop motherboards. before it was like few blowen normal capacitors you change them and bup motherboard back to life :) now there is so much mini components all around i got lost in 1 second what is what :D wow ! cant believe you fixed it like that hahaaha ! GG bro LOL ps: yeah sometimes fans start to spin like crazy for few seconds and than it start working saw it few times.
Wasn't that just a dual npn mosfet? Pin order looks like that...
Salutare, mi-am permis să presupun că sunteți romîn pentru că undeva am văzut nume Sorin.
Eu am o problemă cu un modul de amplificare în clasa D. Avem cîțiva meșteri prin Chișinău, dar fiecare cu problemele lor, fie mereu ocupat, fie necioplit etc.
Mă gîndesc să încerc singur să caut problema, ați putea să mă ajutați?
Modulul se numește Powersoft Digimod 3000pfc. În mediul online am găsit service manual la model foarte asemănător - Digimod 3004.
Modulele sunt echipate cu o placă de control, la care arată un led roșu, care indică "protecție inclusă pentru canalul 1" , modulul este în 2 canale și al doilea canal pare să lucreze normal.

Salut, raspunsul chiar tu l-ai dat, inlocuieste chipul/ic de amplificare de pe canalul 1 :). In viitoar daca mai ai probleme, foloseste cu incredere discordul nostru
I think You had same chip on 2 cm to the right meaby check what it is and buy same part
56:54 Yes it is a duck!!!
