i have this exact same model with this exact same problem. its like this video fell off the sky in my life. you deserve everything mannnNnn
Thank you for being a fountain of wonderful information. Everyone should be eager to rub shoulders with folks like you. You have taught me so much that is useful. Thanks again.
Yes,i like when Sorin use proper calibrated fuse :) Nice job as always,thank you!
Wow.. At 10.39 you stood up and covered some source of light.. Suddenly traces became much much clearer to see..Maybe it would be great to remove that light permanently or just relocate it elsewhere to avoid reflection.. Fantastic videos everytime!
Thanks for the video! I forgot to unplug Lenovo battery and unplugged video connector. Poof, no backlight. Preformed your procedure, diagnosed bad fuse, eliminated other factors and installed new "calibrated fuse". (shhh.... it was really a solder bridge!)
Thank you sir, did the same for a customer and now it works again! Have a nice day. Regards from Belgium
proper calibrated fuse did the job just fine haha i am working on my fuses too using wires from electrical cables i have to calibrate them to different amperage using the power supply :)
Fuse going bad is really common on Lenovos backlit. User error usually.
Usually people not disconnecting batter before the LCD connector. You see a little spark and the fuse opens.
Remove battery always.
Fuses never burn without a reason.there has to be a short between ground to power line of the screen may screen cable scratched and it may do again when flipping screen.good job thank you Sorin
Look at the other comments, lots of people reported same issue and they fixed ei the same way
Where ever your channel goes, I will follow Maestro
Sir, I managed to fix My laptop because of you. It's also a Lenovo thinkpad S145, but the fuse looks smaller and different. And located at the far right corner beneath the cable connector. It gave me 20v in with 0v out. I used wire just like you did, and it's on. Thank you very much. You are King.
I suggest you use a real fuse
@@maklogetrich2378 I understand. But the fuse was so small i couldnt solder a new one on without a magnifier or something like that.
I've just been working on an Ideapad 3 and found the video cable had been badly installed during manufacture in the upper shell - it had been routed over one of the moulded parts, not around it. The cable had physical damage including a burned area & exposed wires... Next step was going to be to trace back to the inverter and see, so thanks for the hints.
I might use a packaged fuse for the rework though... :)
Sorin... next time you have to test the "calibrated" fuse using the bench power supply... 19v 1A and increase Amps on a piece of wire to see "effectively" when it blown
OMG, nice video! I've unpluged my display on powered on Thinkpad Yoga X380 and after reattaching it properly backlight was off and camera with sensors didn't work. Thanks to your video, I've checked all (three) fuses responsible for display assambly power and all of them were blown:) Soldering calibrated fuse solved the issue:) Thank you for what you are doing here!:)
Non si finisce mai di imparare , sei il migliore.
Sicuro però poteva dimostrare a quanti ampere si fonde il filo... giusto per scongiurare che fonda a più ' di 3 ampere... sennò rischiano di bruciare le piste prima del filo.
Thank you Sorin. Have a niiice weekend 😊
Watching and learning everyday from your videos ..Kenya
Another lesson learnt. Thank you
The first repair I ever did, was a laptop shutting down after two minutes. I took off a small panel and removed a carpet from the fan ....... job done.
Man i love this man he is a legend 😂❤️
this channel is well of knowledge. good job and thanks for sharing.
Hello, thank you very much, I fixed it from the same computer, thanks to you.
Thank you for the class, master!
I have seen other people repairing with plenty nice toys to do so, even a real calibrate fuses, but not one of them are even close of your repairing skills. You are the best by far. Many Thanks Sorin for sharing.
its not about repairing skills its about using the proper tools to repair a device, if you go by the book of repairs it is always better to use original or similar parts to repair a device or you can cut corners how its done here.
both will result in the same resolution.
If poop hits the fan the fuse will blow or the cable will burn, aka same result.
I think the owner messed with the display connector while the battery or psu was still connected.
Lucky that no real damage was created.
Just my opinion.
every time Sorin says something is properly calibrated I want to create a meme, lol. Properly calibrated wife, properly calibrated child, properly calibrated politician... ;D
Hahaaa, but you know what, you guys came up with this, i'm learning from the chat :D
Your the GOAT shame you don't really talk with the subscribers I know your busy an all but a random thumbs up would be awesome for some people either way your the GOAT man
Im agreed on you, because of him my costumer now is Amazed and feeling Satisfy and ofcurse Me too😁
Thank you.. it works.. God blessed..
Thank you for sharing your knowledge sir,godbless you
Nice work Doctor Sorin
you are such a blessing
Thank you for the explanation about the fan🥰
Done?, Done!... thank you for showing
Dear sir, today you become my master!
Thank you very much for the help..thank you for the clarification..good luck
Hi,,fuse is 3A_32V_ERBRD3R00X,,thanks for your videos
Sorin's "proper calibrated fuse" lol 😂😆😂
My first teacher and best
Thank you Sorin
Thanx worked for me. Then the screen went blank again. Bridged another fuse on screen as well. Still working now.
Months ago I had the exact same laptop and fixed it the same way. (same properly calibrated fuse)
"Proper calibrated fuse". Haha!! 😂😂 Good one!
good job mate.
i love you calibrated fuses :) its always make me laugh , but hey you do what you can do , the way i am say you improvise :D good Job
There are few laptops that can turn off the fan and if you overheat the chip, it will lower the frequency and shutting down if it reaches over 100 degrees
I think those who said that the fan was disabled in bios ...... Were seeing "Switch off monitor" in bios.
Also please remove the Helium content on this channel, to your dedicated Helium channel! Thanks!👍
Thank you
nice sir thank you ver much
hi thanks for the video i have the same problem no backlight in my lenovos screen but when i connect my laptop with other tv using hdmi port i can see the picture from you experience is the problem in the screen it self
I love it wen you say calibrated fuse ..you now people will laugh about it i still do lol.
thanks ,it help me a lot
Thank you verry much master :)
Proper calibrated fuse 😀😀😀
Regarding the msi laptop fan repair. On my msi laptop at least, 90% of the time my msi ge72vr6rf is using the integrated gpu rather than the gtx1060, so the fan is off most of the time. As soon as it switches to the gtx1060 the gpu fan switches on.
When he soldered the wire, how did he know the polarity? how to find out where to solder the wire?
Gracias, me funcionó. La placa venia diferente pero identifique los componentes.
you helped me a lot!! +5
mr. sorin style the savage way broot force
Thanks Sorin!
I guess you need to have the ribbon cable plugged in when you test for a short!
No surprise that you don’t find any short after the fuse with an unplugged cable 😊
nice easy repair for you today :)
In one of your videos you could burn a proper calibrated wire fuse with your power supply.. Just to check the melting current..
I mean.. Let's burn some wires and calibrate them
thank you master!
nice job, thank you !
GRACIAS DENADA !!!!
Good job
Hello
That is one way to make a fuse. However, what if it short again and short something else out?
Thanks b
I'm newbie in electronic repair but I don't understand if the cable used as fuse is really calibrated for some amperage....
Good job thanks.
thank you sir...
I got a IdeaPad 3 15IIL05 same as the one in your video, the power light just blinks like two times per second, the battery charges, but the laptop wont come on. Do you have an Idea where to start checking?
miss your daily videos sorin ....why you changing your helium has people been complaining coz they are not used to these videos i like the helium vids .keep up the great work sorin
As usual, very informal Sorin...but very laxing too...or is that just me?
thank you for the video, I have the same problem but my laptop is the 5 15iil05 and its deferent motherboard, I try to find the fuse but I could not, is there any advice? please
Thanks sir
Can i get some quick information on how that cable fixed the problem?
Nice fuse😉
Unrelated, but which usb monitor do you recommend for checking power?
I have a Lenovo L340-17API laptop with g542 fg543 fg742 nm-c101 Motherboard. I am looking for the fuse for the backlight display. Would you be able to help? I was changing my screen and did not disconnect the power.
But what caused the fuse to go out originally?
They probably tried replacing the screen without fully disconnecting the battery. I remember accidentally doing something similar like that a few weeks ago with a different model, and now it has the same backlight issue.
tanks you
Hi i have Lenovo Ideapad 3 14ITL6 ( SSD Storage) and the Backlight Display Problem, I can see logo and everything but the display dark. I can't see the fuse.
BIOS UPDATES will cause this! Ask me!!
something keeps shorting, tried this and the thing wont turn on unless I disconnect the fuse.
can i ask why dont replace the capacitator?
SIR MY SONY VAIO LAPTOP IS STARTING BUT THE SCREEN LIGHT IS NOT LIGHTING, THE SCREEN IS SHOWN BY TORCH
does anyone knows how many amps is this fuse? thanks
Unde poți pune o sârmă, e păcat să nu o faci.. mai ales că-i calibrată..
i have a stupid question: should i unplug the power cable AND the battery before playing with the screen stuff?
No, you shouldn't. You MUST do it or you can damage the screen and the mainboard itself.
Totally refused on idea pad3
i dont understand how he found the problem can someone explain?
Calibration fuses are working properly 🤣
So what would happen if its shorted behind the fuse when you inject 11V into that capacitor?
The power supply will show the maximum threshold of amps tuned by Sorin and the voltage would show close to 0 volts. That's what the PS check is all about; determine how the circuit reacts so you can make a conclusion or assumption.
@@rolandberendonck3900 So Voltage would drop cause of the short... And Amps go to max. setting and something would start to heat up...
Yes but you need to have the ribbon cable plugged in to test for short ! Otherwise you are testing an open circuit; right?
@@adeltorjmen7508 I think not if the cap is shorted but dont ask me... ;)
@@Dragunov1111 indeed but this is easy to test 😊
too much time spent on calibrating that fuse, but other then that its good
