I worked for a company that had 120 of these laptop's , had to repair 8 all had the same problem, I am amazed you found it without the schematic or Sony's help ,great tech work ,my hat is off to you.
I love seeing how he over comes problems like this. Other people you see on RUclips will harvest components off other devices and not really explain what is happening so you don't learn anything. I know you describe it as dodgy fixes in your other videos but I'd call them genius fixes. Very clever guy, best repair guy on RUclips.
guys you miss something! it is NOT complain. it was a joke. When I've hear what Sorin said, then i start to laugh. I wrote it here to point for everyone how funny moment it was.
i always get amazed when Soren can find the problem when he doesn't even have a schematic to go by. He uses deductive reasoning to help narrow down the problem and is always successful. Amazing video.
your r my every things for me i have not taken any course and any training from any institution. but i have a service center and i service people because of you u r my every things things my mister, my teacher and every things...
In last one week I patiently watched most of your video's. Genius may not describe you. You are far above than genius. The one thing I could learn from you is that that you must be perfect in your basics. That's it. Your video's are Hitchcock movie movies. I see Sherlock Homes in you. Hollywood / Bollywood thriller are nothing in front of your ability to find the exact fault and icing on the top is how you give a solution to problem. Hats off !!! Very warm regards from India. PS: Just a bit curious... want to see how you put things back as the way you scatter the removed screws all over the table, it would be very interesting to see. Hope in next video you can demonstrate that ability as well.
thank you very much,that`s why youtube is a very good place and people sharing their knowledge in youtube is a very good think.Thank you sorin for your knowledge and experience we love here as always,greetings from norway.
Ribbon cables everywhere! It was frightening when you removed the keyboard and revealed the Sony-style compact motherboard layout. I learned to stay away from trying to repair Sony items after trying to fix multiple PS3's. I'm sure it's a nice laptop. But if yours breaks, send to Sorin! : )
Very good job my friend ! Most of the Electronics-Computer technician they do not Have the Luxory of the chematics! Nice to see and to face the roots the problerms of a lot pf Repairs! Please Keep going !Thanks a lot!
Fantastic video Master...thz for the lesson...i wish i had you as my electonic professon in school...thx for sharing your knowledge...im learning a lot!
You are real help us, Alwah bles you, I think all most problem in the sreen Fuse, many laptop we dumped of this problem be4, but now I think I can success, thanks very much. I will find your next clip INSHAALWAH
Hi Sir and many many thanks for sharing all this. if possible please I need an information. I blown a backlight fuse on a ThinkPad T460S replacing the screen and not removing the batt ... As a emergency repair I just short the blown fuse (sony genuine fuse :) ) but I want replace it. now I know that is next to impossible to find a identical fuse , but can I use a generic 3A SMD fuse instead? (I`m not in repairing computers but I work in automotive electronics) many many thanks again and all the best
It’s hilarious how many people give Sorin thumbs down for doing a real life repair. Just shows how old school and new generation is different. The new generation is affraid of smoke and us old fukers know when the smoke is out theirs no farting around now. It’s easier too fix.
It's not about generations most likely these people complain about the proper calibrated fuse he uses so they get mad lol he even offered them sony fuse and they still refuse haha or maybe they weren't expecting him to find the fault at all
Great video! I don't know if I had more knowledge or more fun in this one... "We don't know nothing" and "Sony proper fuse" :) and gerring seous: Fuse in the ground? I would never find the voltage was from the other side of the inverter. WOW
Rewatching this one and i forgot to post a comment haha even the sony slogan is make.believe so you made a sony fuse lool and you believed in it and it worked honestly you nailed it finding that resistor good work
42:49 I'm always afraid to put too thin wire. How do I know - how much current that small wire can handle? How much amps backlight takes? Maybe it will be fine, or maybe that wire will be hot and will burn in few days?
Hello, i like what you do every day. I have one problem with this motherboard for Asus G73JH, i dont have backlight but i find a burn component wich i think is an diode. On the motherboard it have the inscription JP6599 but i dint find any schematic for this motherboard. What kind of diode it can be ?
Hello, Sir! Can an inverter with problems cause a laptop to not turn on properly? My problem is with a MacBook A1181 that turns on, blinks the grey screen, makes sound and goes dark - keyboard not operational. Thanks!
Hello. I have a problem with my HP6820s backlight. I have image but no light. I move the monitor to the other same laptop HP6820s and is work, have light. The problem is not the monitor. Sometime when i disconnect the monitor from motherboard and reconnect goes to work until i shut down the laptop. After new restart ,again i have image but no light. We remake the flow on the motherboard display connector but still not work the backlight. What we need to checknin this case? Regards
Hello, maybe Sorin or someone else had experience with asus n53 series motherboards? Symptoms are black screen, fan spinning, no error codes. All voltages are ok, tried all basics checking. I suppose it might be GPU, but before trying to reflow what else could be bad with these kind of symptoms? What are bad South/Northbridge symptoms?
do you have gt 520 there? but even yes, that laptop should have two graphics. Intel HD + nvidia. if nvidia dies then laptop should come on normally because it starts always with Intel. and that Intel graphics is inside CPU and Cpu is in socket, so it can be easily replaced. You should start with this. other things to check different Ram reset bios settings by removing rtc battery and main battery. check rtc battery voltage (some laptop will not coming on with voltage below 2.8v) take out all other things from motherboard - USB cables, keyboard, touchpad, just leave motherboard and power button. then disconnect even the LCD cable with screen and connect hdmi / vga cable then start the board. then you should desolder bios chip and put it to programmer tool. Save original bios to disk and then Flash new bios dump from internet. If you have oscilloscope then you should check if chipset is taking instructions from bios chip. othervise you have to replace it.
@@Radek__ Thank you for response. I tried almost everything you said, just not the bios chip. I dont have oscilloscope or bios chip programmer tools. So computer does not even check nvidia gpu when it starts if it has Intel hd graphics? I thought maybe he tries to check gpu and then stucks at checking if its faulty
it is possible -each motherboards and self test are different. But I saw and I have few laptops with dead dedicated graphics and they working fine on Intel and nvidia was gone /disappeared completely from devices menager in windows. but how your issue happened? how it started? did you clear bios settings? I had one laptop where in bios was an option to use two graphics or Intel only or nvidia only and nvidia was dead. this settings was set to nvidia only so motherboard wasn't come on (black screen)
@@Radek__ laptop was not mine until now so i dont know how it failed. I removed both batteries and left it long time, that should clear bios? Maybe i will try to short cmos battery pins to be for sure. What are the cases when computer is not repairable?
yes I forgot to tell you. if the main battery and charger is not plug then you can take out rtc battery and short pins in socket. few second is enough. then be sure to have heatsink tided to Cpu and chipset and fan connected. some motherboards will not start without fan. the Cpu and chipset is getting warm? did you check with finger? very close to Cpu you should have two or three big coils. one (or two) for Cpu and next one for Intel hd inside Cpu. what voltages do you have on them during start? and also on the coil close to chipset and next one close to ram
I've replaced an LCD innolux n156bge L41 Rev C2 with a Rev C5, they are supposedly compatable BUT I have not but screen is black. The laptop is working Toshiba L50 B . Any suggestions? The connector lvd lead is a 40 pin
Dear sir i couldn't continue my study because of the poverty and couldn't be a technician but your video gave a self confidence and made me TECHNICIAN.....hats off sir and much respect
Hey men i love your videos i watch your every video i do and that works so i have come laptops 💻 thats no one can do just like u so if i tell you problem that i cant do can you please make video or ans me for that?????
when you check any components by Multimeter please show us how you are using. where you place positive probe and negative probe exactly. your tutorial is very important but it is abstract.please show us.
Another great video,fuse blown..hehe :) but why do you replaceit with a wire...? Is it a safe replacement? I mean,is it a quality repair,for a blown fuse?
I worked for a company that had 120 of these laptop's , had to repair 8 all had the same problem, I am amazed you found it without the schematic or Sony's help ,great tech work ,my hat is off to you.

16:28 sixteen minutes past and: "what we know till now? - nothing. Absolutely nothing."
hahaha that was nice! :D :)
Yeah I noticed that too :))
This is a school (the best you can find) not a solution center. If you are smart listen and learn, there is a lot to learn.
guys you miss something! it is NOT complain. it was a joke. When I've hear what Sorin said, then i start to laugh. I wrote it here to point for everyone how funny moment it was.
This is what happens in real life, I've spend hours just trying to figure out what happens sometimes
I'm proud to meet your channel,i learn lot of things here.be blessed Sorin
I stopped watching thrillers.
Your videos are better!
One of rare cases when it's actually the fuse! Thank you for a new lesson and a good job :)
i always get amazed when Soren can find the problem when he doesn't even have a schematic to go by. He uses deductive reasoning to help narrow down the problem and is always successful. Amazing video.
I don't know why RUclips doesn't often suggest your videos when searching laptop fixes. Just one video I watched from you I'm compelled
your r my every things for me i have not taken any course and any training from any institution. but i have a service center and i service people because of you u r my every things things my mister, my teacher and every things...

Good to know that you learnt pronouncing 'Schottky' and I learnt fixing screens. Great! Keep it up...
thank you very much,that`s why youtube is a very good place and people sharing their knowledge in youtube is a very good think.Thank you sorin for your knowledge and experience we love here as always,greetings from norway.
you are number one in electronics repair
That was enjoyable watching you trouble shooting this laptop. I enjoy your work flow videos the most.
Thank You for sharing.
You did good sir and your right usually the FL boaster circuit is in the LCD Bezel with the LCD display.
Hello Sorin. Missed some of your Repair vids now looking to this one thank you
You always seem to bring me back to 2005-2010 on all ur videos haha and i find myself screaming at my screen at you lol
I'm doing the same :-) sometimes I want to help him but how? :-) but other time he shows me something that I didn't know before.
Thanks, you could have just test the screen by using different screen but you showed many possible ways to detect the possible failure!!
Proper Sony fuse 😂😂😂🖒
Ribbon cables everywhere! It was frightening when you removed the keyboard and revealed the Sony-style compact motherboard layout. I learned to stay away from trying to repair Sony items after trying to fix multiple PS3's. I'm sure it's a nice laptop. But if yours breaks, send to Sorin! : )
Another great video!! It feels like Christmas, thank you for this video.
Sorin Brand fuses now available ... At the mains lead section at your local hardware store :D
Perfect job Sorin
Sorin I have a laptop with the same problem no back light. I will try to repair it using your video awesome work love your videeos.
You are very talented sir
Sorin... you are my best teacher!!! thank you!!!
beispielose geduld! totale leidenschaft und Neugier! bist eine große Bereicherung für unsere FIrma!!!
Yes, got here a Vaio too with the fuse open on the main power rail led conector. Thank you
Very good job my friend ! Most of the Electronics-Computer technician they do not Have the Luxory of the chematics! Nice to see and to face the roots the problerms of a lot pf Repairs!
Please Keep going !Thanks a lot!
amazingly this was one of the hardest and at the same time shorter video
Fantastic video Master...thz for the lesson...i wish i had you as my electonic professon in school...thx for sharing your knowledge...im learning a lot!
Pure knowledge & experience applied. Very good, thanks!
You are real help us, Alwah bles you, I think all most problem in the sreen Fuse, many laptop we dumped of this problem be4, but now I think I can success, thanks very much. I will find your next clip INSHAALWAH
It's called a Romanian fuse / aka "litza" / "lita" :)) . But very usefull
Hi sir good to see u in new video.... To be continued
When he said , "lets replace it with proper sony fuse " i nstantly i had smile on my face and I exactly knew that its gona be wire or solder bridge 😀
You got lucky with that resistor! I did the same on a client and after three days the laptop came back in fire! Hahaha
Fuse on motherboard ? maybe ? +19v
haha great video on 33:24 "nothing is logical, WOW!?!?" had a good laugh on that one
Sony fuse is working great 👍🏻
Now putting back to getter will be a lot more time I think 🤔
You are great man my hat is off to you boss....but how can I get know these things better I need thy help plz
WoW Sorin its issue from hell, i didnt belives that you can fix it, after this, i think you can fix anything
thanks for share your knoledge you got a new subs !!!
Thank you ... from you learn to learn
Hi Sir and many many thanks for sharing all this. if possible please I need an information.
I blown a backlight fuse on a ThinkPad T460S replacing the screen and not removing the batt ...
As a emergency repair I just short the blown fuse (sony genuine fuse :) ) but I want replace it.
now I know that is next to impossible to find a identical fuse , but can I use a generic 3A SMD fuse instead?
(I`m not in repairing computers but I work in automotive electronics)
many many thanks again and all the best
THX!! :-) That was very helpful. I learned a lot today.
It’s hilarious how many people give Sorin thumbs down for doing a real life repair. Just shows how old school and new generation is different. The new generation is affraid of smoke and us old fukers know when the smoke is out theirs no farting around now. It’s easier too fix.
It's not about generations most likely these people complain about the proper calibrated fuse he uses so they get mad lol he even offered them sony fuse and they still refuse haha or maybe they weren't expecting him to find the fault at all
you are great sir... i've tried your solution, tested and proven...
Maybe,, no...hmm Maybee, noo...no way... Maybeee, NOOO.! Thanks for sharing, Master.
Thank you Sorin
Great video! I don't know if I had more knowledge or more fun in this one... "We don't know nothing" and "Sony proper fuse" :) and gerring seous: Fuse in the ground? I would never find the voltage was from the other side of the inverter. WOW
Whatta guy! Another great video of yours!
Rewatching this one and i forgot to post a comment haha even the sony slogan is make.believe so you made a sony fuse lool and you believed in it and it worked honestly you nailed it finding that resistor good work
thankyou for upgrading my knowledge. godbless more videos to be upload
Thank you, I have a question a risistor is not a fuse it reduces the voltage making a short doesn't affect the work of the inverter
very nice ! more to learn ! thanks for the video..........
Phonce Amocap f9gixuxyaid8e7d9gogb b . Lvlm . M kcjdy
I have issue with few laptops some have dim screens and some do not start, i am wondering if i can send them over to you to fix!
Thx
Nice job soren . How are you ?
You are so good. Wow! Thank's for sharing! Experience, that is the secret.
43;00
Which cord or cable does he solder in there to solve the problem?
Very nice😃 thanks for sharing
42:49 I'm always afraid to put too thin wire. How do I know - how much current that small wire can handle? How much amps backlight takes? Maybe it will be fine, or maybe that wire will be hot and will burn in few days?
25volts and lcd will be less than 20w,so it like 1A. And it very short wire so it can be thin
Great video sir. How about black or white screen? Thank you
Love you man. thanks before watch
You like smoke dont you 😂 Nice work as allways
It's also a nice job of you 👍
I am still using it, such a nice and reliable laptop.
LOL.. what a sony proper fuse, tysm
Hello, i like what you do every day.
I have one problem with this motherboard for Asus G73JH, i dont have backlight but i find a burn component wich i think is an diode.
On the motherboard it have the inscription JP6599 but i dint find any schematic for this motherboard.

Did he reply to you?
Thank you a lot for your efforts i appreciated
wow this guy is proper amazing.
very nice video

Made in Japan is always different. Good job master. you found it less than an hour.
"Let's check some voltages"
Awesomely done! 🤸♂️
great job
Another good video. Thank you.
you are the best man ..

This is more entertaining than the IMAX

Congratulation 50k
sir ..which kind off adapter sir using for find short
Thanks, very interesting.
Its a fantastic job
46:20 Why screen is at 4:3 format mode? It was like this before windows starts as well, so it should be an option to "stretch" in bios settings.
We install a fresh wind 10 and the picture is full screen, nothing wrong
Watching just now 2021 and its fantastic. I laugh when he said i have many fuses here . Hahhahaa hahahahahaha
Hey men i love your videos i watch your every video i do and that works so i have come laptops 💻 thats no one can do just like u so if i tell you problem that i cant do can you please make video or ans me for that?????
thank you sir
very nice sony fuse
Proper Sony fuse” 24 awg wire lmfao. Works every time lol
sorin you in this learning video too many jokes crack
I have a similar problem with my laptop. The screen dims and discolors. Can you fix my computer? Please, reply.
when you check any components by Multimeter please show us how you are using. where you place positive probe and negative probe exactly. your tutorial is very important but it is abstract.please show us.
Superb
Another great video,fuse blown..hehe :) but why do you replaceit with a wire...? Is it a safe replacement? I mean,is it a quality repair,for a blown fuse?
