I am a technician from malawi that is africa, since istarted watching your videos my my working experience and confidence have boosted and my repairing skills are high. i make more money now. you dont know how much help you are offering to us, keep on
I just rejected a board with a short to ground, an exploded first mosfet and the 19v rail fused to whatever was below that mosfet (probably 12v). I could try again but there are probably a lot of dead stuff on that board anyways.
Honestly, when I saw that burned motherboard I thought the laptop was a "no-fix", but he actually repaired it. This guy is unreal, what a legend! Love it when he says you don't need capacitors. Haha
This Is True and only Sorin! This is the core and essence of electronics repair school! No other channels needed, Sorin with gloves is not the same teacher as here. Keep going no matter what, discover new ways, take other routes, make the device live again. I`m watching ERS from a long time, but I can only tell You all one thing - No matter what channel - Our Teacher`s personality is Uniqe ;) Regards Master!
I have bad news for you Sorin fanboys. A laptop turning on does not mean the laptop works 100% fine. Power rails were lost. Capacitors lost. Who knows what else was lost.
Excellent and amazing professional repair as always. When I saw that highly burned board I thought that laptop can't be fixed and will never work again.
By definition this job ain't dodgy at all..I see a technician who go beyond extra mile in his work..if this laptop would have been taken most of laptop repair guys they would declare it junk and mb replacement but Sorin here believe in his God given skills to bring it to life..I see no dodgy here..my opinion your the best.
This is the second or third time I watch this video. It blows my mind every time. When I saw those capacitors I was sure this board had left this world. But you bought it back to life. So cool! I wouldn't worry about the fingerprint reader like you said. The fan though needs replacing with a new one. The fan is important.
@Mr Guru Not on this laptop though. It depends on the fan. If the fan is serviceable, they can be cleaned and oiled. This is a cheap consumer laptop so it does not have that possibility.
Sorin, I have seen you do some dodgy stuff but this defies logic and everything I have learned about electronics in the last 50-plus years. Only you could get away with this, I laughed so hard at this video my sides hurt, I kept telling my friend, watch him, he just keeps scraping away the burnt parts, circuit lands, and board material until the short goes away and he won't replace any of it but for some unknown reason known only to the creator the damn thing will work! If I send you my test leads will you bless them or rub them with your magic fingers? 🤣😂😁😄
Sorin incredible job. Just one question did u put the notebook under load test after you put together. I wonder how it behaved under load, i mean as you said the board could burn more and best way to see that is to test under load. It is lways a pleasure watching you. Apart from that you dont do dogie repairs, while you have a good knowledge and understanding of circuit, and working of circuits you sometime show us a different perspective of solving the same problem. I am veteran engineer for 35+ years experience in Electronics and I love my job because i belive that ELectronics is Magic and people working on this subject are magicians and Sorin my friend i have seen a lot magicians and you are one of the best . Keep up your good work and share this magic as you always do. Lots of regards rom Istanbul/Turkiye.
this video confirms two things, the first you are truly a master, the second is that the pavillion dv6 and dv7 are among the shittiest laptops ever produced. However, you know, they gave me one and I repaired it thanks to your advice. Mosfet burned? No problemo amigo, a bodge wire and we are ready to go!
When you said will fail rf specs had trouble getting up from under the table laughing. And have I done dodgy stuff myself... Keep it up Sorin. You are the real electronic. Hey, you could even use the thermal camera to get the spark temp hahaha.
Nice job! This video deserves the nobel of dodgiest laptop motherboard repair ever done to global history! 👏🏼 I congratulate you after that even if I don't believe it will work flawlessly after so much burn but who cares! It did pass the post screen so yeah perfect that's amazing news! That fan is 100% serviceable and you can remove it, unscrew the cover screws and open it, clean it, grease it and close it after changing the thermal paste and maybe a small thermal pad (it depends from the board). Well done Sorin. 👏🏼 Greetings from Greece 🇬🇷
you can find similar ones where solder is used to rebuild connections etc...after some time you know what is possible :D Though you can get a DV6 for 70GBP. It probably will burn after a few months though. Nevertheless another nice repair, thanks to Sorin.
Can you help repair a laptop motherboard that had a burnt through an hdmi connected. The burn is not as much as this that you repair. My laptop is a Dell Precision 5530. I will be glad if I can be responded to. Thanks
DV6 is from 2006-2007 and limited to 4 GB and Intel dual core. It can run Windows 10. I know because I installed windows 10 long time ago on a DV6. But really old, so there must be a sentimental reason to get it repaired. I'm typing on a DV7-1025nr, the model after the DV6.
I replace the fan and replaced a burned capacitor and installed latest linux mint on it and using it to connect to my 75 inch led tv to watch youtube this video
I was repairing in the US until 2018, used motherboards were cheap and I would just replace it, total cost of repair to me was about $60. I lack the talent to even try to fix that.
Sorin is amazing, but all you guys worried about what he's inhaling must not have seen to many of his videos. Since he sucks on poison oil smoke sticks on purpose, why would he care about inhaling a little poison from soldering?
Good day sir. i have a hp dv7 i7 cpu and the batery wasent working then i got a power spike and now the laptop is not showing on the screen but it comes on and the caps lock is flashing .do u have a tipe where to look to get it on please sir
Mr. Sorin - working on a Microsoft Surface Pro 4 battery not charging at the diode cathode side -12VDC anode side when i first plug in charger i have 8VDC and after a few seconds drops quickly - suggestions? wanted to discord but it won't let me in ???
Don't need any fibre, why? Like sure if you wanted to do it for real real you could take epoxy and you could take some fibreglass chopped strand mat, chopped fibre, but normally what i've seen is a little too coarse and not needed for a hole this small, and you need to take precautions so the glass doesn't go everywhere, doesn't itch you, doesn't go into your fingers or under your fingernails, doesn't get into your lungs. Lungs are bad time. The original PCB substrate is glass fibre continuous mat saturated with epoxy, but there is enough structure in the rest of the PCB to carry it, adding glass fibre to a small patch like that won't make a difference i think and you'd rather have the patch more flexible than too rigid, so i don't think adding glass is helpful, it's even more likely to tear up at the connection since your patch isn't continuous fibre with the rest of PCB. One choice is to use "UV Soldermask" resin. You can get a 400nm flashlight that's good for it to set it instantly, or UV gel fingernail curing light. Use thin layers, but eventually it'll cure through once kicked off. I'd just use 5minute epoxy in a pinch, and help it along with a little hot air, very little heat and keep the PCB at like 60-80°C. You can even layer new copper on top and rebuild components as well if you like.
I used to sell those laptops, when they just appeared on the market, until i found out they were firecrackers, they looked nice......but after that it was based on luck, how long will it last.
previously I've repair this laptop (a customer), which has overheat issue, but it's the i7 version can't believe this laptop is still working, a lot of dust, I cleaned it, change the thermal paste and the laptop still working fine
Computer fans that dont spin properly can be taken apart and greased and they will work like new. The fan is attatched to a metal pin that goes in to a small bearing. Under the label is a lock washer that you have to remove first and then pull the blade out. Its always good to use WD40 to free the fan blade pin once you have removed the lock washer. WD 40 will also clean the dried grease before you put fresh grease.
Hello hope you’re having good day. I have the same notebook black screen, caps lock blinking 5 times, wifi orange and the issue is motherboard can u please help me to find the problem plz?
Some noisy fans are easy to fix, just lift the sticker and if your lucky there is a Rubber Plug under the Sticker, pill the Plug out and drop a couple of drops of PTFE Lubricant on the Bearings and the Noise is Fixed
It can't possibly be fractured? Or you wouldn't have much going on at all even after the substrate burn is cleared. Like the SMC does a lot of stuff, a lot. It's probably just filthy with normal dirt.
So why put the capacitors in in the first place? And since that part isn't functioning anymore, something has to be without power, right? Sooo.... I don't understand.
this fan can be disassembled, 4 screws to be removed from the radiator assembly and you can pull the blade out, then clean the old grease (inside the sleeve and blade)and put a drop of 10-w40 or whatever you have. But only if the fan sleeve is ok.
@@agutek It's a knowledge based assumption. Without capacitors the laptop will degrade quickly over time, stability of the system will be ass, if he can even do anything remotely more demanding than word and youtube.
From a Techs point of view I scrap that board and put it in the parts bin for parts use only and I put either a recon board in that hp or a new board. by the way you know what HP stands for dont you HORRIBLE PRODUCT
Meh, this laptop probably doesn't need half the stuff on it to work... Chop it off, Heal the disease ! By the power of Sorin, I command you to Live ! Bwahahahahah

Most repair guys would just reject this job.. Appreciated your effort Mr Sorin
I just rejected a board with a short to ground, an exploded first mosfet and the 19v rail fused to whatever was below that mosfet (probably 12v). I could try again but there are probably a lot of dead stuff on that board anyways.

he's right, i broke a filter cap off a ps4 a few days ago, it had a clean short on the main 12v rail 🤣🤣, it's running great now
cap was cracked by the way, that's how i knew there was something wrong with it, ps4 took a fall, drop damaged the cap
amazing what you can do once you understand how things work.. bravo Sorin!
Could replace the board as well as the fan

I have bad news for you Sorin fanboys.
A laptop turning on does not mean the laptop works 100% fine.

BTW, your a Champion don't change your ways please.
Excellent and amazing professional repair as always. When I saw that highly burned board I thought that laptop can't be fixed and will never work again.
if it was within a powersupply circuit, its done. on the 19v rails u can do a lot if u have the knowhow..
Hi Sorin, i watch your videos so much and thank you i am learning a lot. Im in Africa Zimbabwe. I repair laptops and all thanks to you

he literally brought a pc back from the dead, great job Sorin thankfully this pc wont end up in the landfill
Wow, amazing repair. Maybe the fan can be repaired too with a cleanup and a drop of oil in the bearing under the label .
@Mr Guru Not on this laptop though. It depends on the fan. If the fan is serviceable, they can be cleaned and oiled. This is a cheap consumer laptop so it does not have that possibility.
Love the channel. Awesome you got your radio license, I'm an extra class in the US. I enjoy watching you problem solve.
Thanks Dan W1UWC
That’s a real repair and I like this things to watch. Thanks 🙏

Dodginess at its finest but i love it because you just save a laptop to go to waste. Thank you Sorin.
It's either a cheap dodgy repair BUT with a working laptop OR no laptop 😅😅 so, yeah...
Another great Doddgy job keep them coming .
Very interesting breakdown.
Thank you
Thank you sir sharing your experience
Amazing repair. Ah, that hole.... don't worry about it. 😎
A couple of holes and rip off a few components, and voilá, computer fixed and lighter. Win win.

Thinking the same. Might not last long.
You need to have UV solder Mask BTW great video👍
@Mr Guru I use nail polish. Cheapest one. Lights up under blacklight 🤣
Great job. If fan bearings are far gone, just replace it is a better and cheaper solution.
A good one for learning and understanding the concept of how to handle it is worse case mother board sir nice one
Wonderful video sir. Thanks for sharing 👍
Brilliant Sorin thanks for the info
You are Master Sorin. Im surprised you spend time fixing a $25 motherboard 😁. But good lesson on burned layers
Amazing fix, the magician strike again.
Alto socavado, pense que moría ésa notebook, buen trabajo amigo
También yo. Cuando la miré dije: ''No, ni loco''.
this video confirms two things, the first you are truly a master, the second is that the pavillion dv6 and dv7 are among the shittiest laptops ever produced.

Hey Mr Sorin, treat yourself a grinding pen, trust me you will love it 👍
you should use a grinding pen or a dremel with a grinding bit to make it easier for you nd much faster
this is more russian style repairing.. no need for fancy northfix tools
@@Arvidje Yeah. Sorin would use his bare hands if he could 😀

Hey Sorin, what happened to your electric screwdriver? Thank you for your amazing video as usual 😊
I was going to ask the same question!
He probably took it home, always see it in his home videos
Me: hello Dr dentist, just a clean up.
Dr Sorin: Let me just grab my pliers.
Great job
❤ Awesome Mr. Sorin !
Great machine, never burns
That is a extraordinary video thanx
come and watch Sorin doing root canal surgery on HP DV6 motherboard..:)
Do you sold the aspire 3 N20C5 no power ill check the mosfet charging is good but in batery charging its low amp...
Why you don't use a Dremel with a small bit grinder? will be easier grind and smooth all that area.
:) sometimes substrate shorts can be "solved" ( it's rare btw)
So rosin it's a good alternative for UV soldemask 😁
well done. 👍
Brilliant. First time I’ve seen the rosin trick. Thanks
Good video, it's not worth taking the chance using this again because it could start a fire,
Can you help repair a laptop motherboard that had a burnt through an hdmi connected. The burn is not as much as this that you repair. My laptop is a Dell Precision 5530. I will be glad if I can be responded to. Thanks

Hey Sorin, do you use a fume extractor for your repairs?
No. He smokes; he does not care about his lungs.
its for fearfull repair guys.. typical the people that are even wearing glasses while turning on a laptop..
what ever DV line is hell on eathth DV6 will never pass my door.. that garbage from Hp shut not even exist
