Lenovo ideapad 3, no backlight repair, a easy one

[@manuelapacheco9129]

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

[@peterdobson3435]

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.

[@FoCuSonWaR]

Thank you sir, did the same for a customer and now it works again! Have a nice day. Regards from Belgium

[@CoryThompson8080]

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!)

You save my life, thank you so much i restore the backlight of the lenovo idea pad 3

[@tongravity5668]

Yes,i like when Sorin use proper calibrated fuse :) Nice job as always,thank you!

[@GABRAN47]

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.

[@maklogetrich2378]

I suggest you use a real fuse

[@GABRAN47]

@@maklogetrich2378 I understand. But the fuse was so small i couldnt solder a new one on without a magnifier or something like that.

[@saetto84]

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!

[@knightwar3]

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 :)

[@teknogod17stinnett78]

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.

[@roccosmitterson9994]

[@laboratorioassembler]

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.

[@valuxin]

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!:)

[@mardina1a]

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

[@silviuguseila2552]

Look at the other comments, lots of people reported same issue and they fixed ei the same way

[@PSB0nd]

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... :)

[@chrisconlon7970]

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.

[@domtechelectronicsrepair6360]

Watching and learning everyday from your videos ..Kenya

[@laboratorioassembler]

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

[@M.A.martin]

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.

[@gershonlapokimon4698]

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.

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

No, you shouldn't. You MUST do it or you can damage the screen and the mainboard itself.

[@laypyu]

"Proper calibrated fuse". Haha!! 😂😂 Good one!

[@trilexfix]

But what caused the fuse to go out originally?

[@renhaker]

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.

[@saetto84]

In one of your videos you could burn a proper calibrated wire fuse with your power supply.. Just to check the melting current..

[@saetto84]

I mean.. Let's burn some wires and calibrate them

[@Dragunov1111]

So what would happen if its shorted behind the fuse when you inject 11V into that capacitor?

[@rolandberendonck3900]

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.

[@Dragunov1111]

@@rolandberendonck3900 So Voltage would drop cause of the short... And Amps go to max. setting and something would start to heat up...

[@adeltorjmen7508]

Yes but you need to have the ribbon cable plugged in to test for short ! Otherwise you are testing an open circuit; right?

[@adeltorjmen7508]

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 😊

something keeps shorting, tried this and the thing wont turn on unless I disconnect the fuse.
