A man who shares knowledge is a respact worthy man... Thanks Sir Big fan Syria

the master of laptop repair

Sorin you don't have to justify yourself to anybody. There are no people on youtube with your style of fixing things and willing to share true skill. This is whole new level of fixing things. And all of us who are watching your videos have choice to repair things on our way or your way. So don't waste your precious time explain anything except how to fix something on your way. Thank you very much for your videos.

8:57 that test point actually reads PWM, not PWR, so that is most likely your "DIM" signal, since it stands for pulse width modulation :)

the major signal to activate the bcaklight is 3 major things .. the B+ PWM and the adj voltage..

Sorin, your overengineered repair audio jack port will outlive the rest of the laptop. True, you spent a few more minutes than just switching for the proper part, but it is also more cost effective than ordering the part, waiting, charging the part, etc... Always Kudos to Macgyver solutions :)

Thank you for sharing your experience

I dont know why you call it dodgey. It works and customer can use the laptop. Innovation of repair. Not everyone can afford 10 hour repair fee for super dio trouble shoot. Well done sorin type for the info.

Let the haters left and you are not dodgy. Good lesson. Keep up

I DID EVERYTHING YOU DID AND IT WORKS THANKS A LOT YOU ARE THE BEST

Many People who call them pro are in fact just sellers, they mostly says not repairable, cost to high, so Sorin Fix things with out pushing for new buying.

The master never do dodgy jobs... When the master did something, we have to shut up and learn... That's the life, good job Sorin

Always a pleasure to learn here! Fantastic channel, keep up the great work, Sorin. Too bad that I do have only two thumbs I can raise. :) Enjoy your weekend

Thank you sir. I watching you about a year. Last 2 weeks i had 3 nice scores: pixel 2 xl - the undercharged battery, Samsung Note 10.1 - slightly pulled screen ribbon cable and Dell XPS 1330 - classic shorted cap, found by your method. multimeter and low voltage + 1 amp current to power rail, splashed by zippo fuel. It was fun. You making a people happy. Hello from Czech Rep.

Great. You made a good work. I can also get your information for my skill up.

Sorin, Great explanation do more of this It helps me to find the fault

You just helped me realize the issue with my laptop LCD backlight! Was the TK fuse (thank you, I didn't know that was a fuse - different fuse). So thank you!!! I don't have to buy a new screen...!!!

Que video q me salvó mi laptop "MAESTRO" Gracias!!! desde ARGENTINA BUENOS AIRES

and always waiting for new videos thanks for the all your videos

I'm not a hooligan I'm still sitting on the opinion that we are here to learn something ,I don't like solutions like oh my laptop has a shorted cap, let's buy a new One (laptop)

Amazing guy , trust me , i am good in repairs as well i repair everything , but to make it presentable like this it takes effort .

About time you work on a t430 I've been waiting for this LOL

Very good repair video

Hi Sorin , Hope you and family,friends and colleagues are keeping safe and well . :- )

i am big fan of the electronics repair school

Thanks for sharing .its Fast and Quick Repair

23:23 That laugh was even more dodgy than that connector. xD

Sir, ești mare omule!!!

New video - excellent.

Great video!

Haha, you could also add a resistor to that bridge just to lower the screen brightness a tad so its not at full brightness which would help battery endurance. Lots you can do to laptops to get around problems and keep them running longer..

Sir, thanks a lot for this vid... i follow your principle and it works for me. thank you very much.

do you know so many Laptops have been declare dead because of this issue God sent Sorin just bring out the secret. only God can repay you. love you man from my heart. fixing without schematics all thanks to you

PWM = Pulse Width Modulation. Used to control brightness as you said.

Well Done again!Thank you!(Bios is frozen because of dead cmos battery)

Thank you so much.

Your videos always is usefuly

Sorin for president!

So the power button can have 1.8v instead of 3.3v that's good to know thank you and nice save

Awesome.. again

you are great sir!!!

Good job bro

added to favorites

Thnx for the video Sorin , i'm so impressed Bravo ! 👍 .. but how you learned all theese things ??

Awesome

If I could do these doggy jobs, I would be glad. Thanks for sharing

We are the same problem and we are the same sokve the problem just make a bridge or junper to light up the back light sooo thank you for another tips and idea hehe

thank you sir

this dude got to be a genius

fantastic

I love U doji man , U have to do same job one day maybe maybe ................................. salute sir 5 stars ✨

Bravo.

I wouldn't worry about the brightness. It would make a great lamp ;)

I do like your videos always what is going on, this is weird, this shouldn't be happening but then you magically fix it

Maestro.

شكرا

you the best

It was inverted : 8:57 is not power is PWM=DIM , and the other pin is ENABLE ,so it was DIM=3v ,ENABLE=0 ,better idea is to bridge EN pin with 5v.In that case everything is working ...Brightness..

Sorin, thank you for all the knowledge you share with us. Personally, I would put a layer of capton tape below and above the bridge to protect the wire from touching anything arround it. I would not trust the thin enamel coating on the wire. I've seen some chemicals (UV cured) that help maintaining such bridges intact and electrically safe but never used any of them. Also please be less dodgy with the laptop screws and use some magnets for them :) Now about the previous video, I did a similar laptop headphone jack repair using an audio extention cord from the motherboard straight out a small hole on the plastic chassi (customer approved the solution). Also tied a loose knot on the extention cord as a mechanical stress relief (not the best solution) and it's still working fine, so yeah be as dodgy as the customer can accept.

sir you r great

sir please do made more videos about inverter and backlights repair on laptop for beginners.

Sorin!!! Come to Besiktas a

So the super io will not develop any problem if that 3.3 is jumped? Thank you

Still curious on this one to know if dim signal comes out of sio. Maybe a broken track or bad connector that could be traced. If sio handles kb signals maybe keyboard is fine too. But I guess you don't have the time. Enjoy a Happy valentine with the love of your life. And I don't mean your iPhone.

LOL well said

I think the pin Sorin shorted was the EN 'Enable' pin. Would love to know if the brightness controls worked in the end.

professional

without having the schematic I believe the signal passes through the dimmer. Without the keyboard plugged in there would be no way to power it on. I think you'll find it works without the jumper when the new keyboard is installed......

Side question: there do you get your is (original) samsung s7 battery?

this guy is like the bob ross for laptop repair :)

I came across your channel 2 days ago. Everything here is crazy in terms of knowledge. I have a dell ins.3537. And i cannot install my dedicated gpu drivers. Every time i attempt installing them my dedicated gpu (ati) starts to make some boiling high pitched noises and my laptop freezes. I also have integrated gpu (intel) that helps me watch videos and overall turn my screen on so i can use my laptop. And i know this aint the place to ask but Can i assume that my gpu is dead ? Any help would be appreciated. Thank you. New sub. Gpu is ati radeon hd8850M.

❤

I was waiting for fireworks. Fcking screens haha.

Hi sir...if i've been replacing the screen with the new one but the backlight still not show up, what is actually i have to check?

Maybe it could have been the capacitor which was shorted? , the one you soldered the bridge wire to under the ic

cel mai des am intalnit problema din multi-io,problema de firmware.ai putea sa incerci cu un update de bios,eventual chiar daca ii ultima versiune ii dai sa il faca din nou daca iti permite.am mai rezolvat problema asa la unele laptopuri inclusiv brand-uri mai cunoscute....oricum varianta cu enable direct pe display ii mai rapid

I blew the back-light fuse on this one while changing the display.

Does someone have a link to the headphone video Sorin is referring to?

18:22 super i/o can pull down to the ground that signal, ALSO if the hall sensor switch is bad (as you know - the sensor, which is checking if the lid is open or not)

Doesn't lid switch stop screen altogether. Data plus bl?edit.. I just tried with magnet on my Toshiba. picture is turned off too, not only BL, if lid hall switch active. Only backlight problem cannot be lid switch problem . on my Toshiba anyway.

when are you going to do some work flows

Hello can you remove parallel lines on lcd? Like single lines blinking then will disappear after 1hour

it is possible that there is no vedio output on the vga or hdmi if super io problem?

Hello i have t430 lenovo. I hate display mate. I can replacent it? 🤔 How?

My T430's backlight is not working. On startup you can see the Lenovo logo (faded) and then nothing. I swapped the screen out 3 times and all of them are not displaying. Is it the fuse on the mobo? Is there a solution for this? Any help would be appreciated. =)

Connect a wired keyboard to the USb and check

like sr, thanks

Are those wires isolated?

Why don't you plug your usb keyboard and check if brightness is at low?

Can anyone tell me how to make lcd 30 pin cable to copy firmware from lcd to another ... because i can't find anyone have this cable here in Egypt

Help me sorin help me!! You have inspired me to buy a iPhone 8 Plus broken. I now got it to work using your videos but I need to know what components on fl3995 and fl3995-1 I think it’s a inductor but I don’t know the spec. Can you or someone help me with some info on this as I can’t find bugger all on the net!

Is this a thinkpad with a liquid damaged "spill proof" keyboard?

Dodgy but beautiful as usual, but wouldn't it has been better if at least you checked for a bad connection in the connector or a blown resistor which is preventIng the DIM SIGNAL TO REACH?

Without a jumper the cost of repair is greater than the customer would be willing to repair

if they would give you the information you need and the access to the parts at a reasonable price.. then it would be different.. But if you know your stuff you can bypass a lot of garbage they put into these things.. Just ask a mechanic, those that tell you they don't do the same as Sorin are liars or have just started to work as a parts changer.. Not to knock the purist at all.. they are right in the fact that in the "perfect" world all things should be done correctly..But as Sorin said.. why take 6 hours hunting down the problem because you have no schematic.. when you can search and not find, just fix it and move on.. From a business standpoint that is the way to go.. If you guarantee your work and it works just as good as it used to.. then I for one wouldn't give a darn if my earphones are plugged into the same jack that was always there or a totally different jack as long as they worked! thanks Sorin.. I for one thing you do an excellent job and in a reasonable amount of time.. as those of us in business know the customer is always thinking we take to long and charge to much..

i have a laptop thinkpad t430 backlight problems how to solve i have soldering equipment i think its a fuse blown and i dont know where is fuse location please share if any 1 know

Sorin or if someone can help please, my laptop screen is 300hz, but now after a year it's start to have a motion blur effect while I'm watching KZread videos. (scrolling and gaming are still smooth) Its not from the drivers, and not from the windows. there is a chance that it's happens cuz a bed capacitor on the monitor board? Please🙌

wow

i don't care if you fix it in dodgy way as long as it can fix the laptop.

Dont ever justify being dodgy, ppl that critize you for that havent being in your situation before. I have fixed countless devices just improvising. Cheap and fast (but working) > expensive and looking pretty.

He should test with another screen that would be faster to find out if the problem is the lcd o motherboard

What if the backlight never goes off when laptop is shutdown
