I liked your approach of diagnosing the problem. Most of the viewers do not have the background to identify which component to check using multimeter. Your way is the preferred way instead of replacing the screen and throwing away the existing one. Thanks for your good work. I wish I could get that kind of training, which I always loved. I liked your style of teaching and have already clicked "Like".

Very helpful video!!!... 1st I had to remove the damaged screen doing exactly as he explained, checked the exact model and rear video connector position, ordered the new screen (making sure it is 100% compatible with the original laptop model + video connector exact location behind), safely store the disassembled laptop parts with care by holding with tape the little screws while waiting for the new part. Once I received the new screen, I followed exactly as this guy explained ensuring that all connectors were properly inserted and... VOILA!... it worked.
>>> JUST 3 LITTLE EXTRA ADVISES: 1) Keep the NEW front protective (transparent) screen cover on it while re-assembling until you need to put the final frame cover. 2) Be careful not to confuse the bottom screws with the LONGER pair that belongs to the plastic screen cover at the end of this procedure, otherwise won't hold it (as I did it), so you have to swap them all back correctly. 3) Ensure that the plastic frame >>cover hinges
Thank you for the video, it’s exactly what I was looking for, my laptop flicking and even in bios menu, I would try this quick voltage measurement to find an issue
Good information. Teach logical way to repair, some times with logic think can find problem easily. At least to remove customer complain... led flick.
I agree most of customer will close the cheapest solution. Good job
Hi i watch all ur videos from 2 years now as like u say u keep it real and the way u solve things through all methods and how to diagnose is simple but i hoope u trun to make videos for smartphones repairs and how to diagnose as beginner repairing electronics i learn much from ur videos thnks so much (follower from morocco)
a greetings from palestine , you are the best teacher i have ever seen in all youtube , big respect for you sorin
Happy Friday Sorin !!
Ce coincidență chiar am nevoie de o rezolvare pentru asa ceva. 👏🏻👏🏻
It could be a missing capacitor or broken track for multiple capacitors on the backlight power circuit, that's causing the backlight to get the "unevened" clean pulse of current. The issue may not occur on charger because in windows settings, the backlight is set to 100% when plugged in, and less than 100% on battery. That is also why it doesn't occur on startup, only after windows logon. The user may have caused that while replacing RAM or HDD, or by slipping a screwdriver in the wrong place
Found ur channel after ordering a dead motherboard for the IDS port replacement. But then, I tried reflowing the board in the oven (ghetto) 2x and it booted. So I have a flickering screen.
And haven't removed or found a IDS replacement for my original motherboard. Thank you for this. Just building something 1st time hoping it works.
If the problem is really coming from the dim-signal of the super io, you should also disconnect the resistor because now youre feeding power into a diying signal line :)
That "Hello finally friday" made me subscribe instantly lol! what a great guy!!!!! ok back to the video
Salut ! Te urmaresc zilnic, ma ajuta foarte mult sa inteleg unele lucruri faptul ca repari si nu inlocuiesti placa / piesa e foarte util cautam de mult situatii zilnice din service uri nu doar tutoriare in care gasesc defectul si comanda piesa . Te apreciez f mult. Exista un forum sau grup in care putem fii in contact cu tine? Mult succes !!!
My first comment on your video...i watched a lot..learn a lot more...thank u sir..
Dam man that's some serious out of the box repair. Nice
Excellent demo.
Wondering if addition of components could be added to smooth out fluctuation. And keep the dimming option.
The owner can use the night mode for adjusting the brightness and colors, it will do a kind of light adjustment..
I have that problem on my Toshiba. Mostly stable video until I adjust the screen angle, then lots of flashing. But sometimes I get a little flashing when it's just sitting there. I unplugged the charger and it started flashing, but then settled down. It may have just been the movement that caused that. Put the charger back in and moved the screen. Lots of flashing but then it settled down. Would love to get it fixed. It's still a good laptop and it's running a website monitoring program for me.
I love what u do sorin it teach me alot
Very good buddy...Nice Sorin
Cool, I hope I can fix my LCD with this and the two other flickering screen fix videos.
thank u sir for giving as good information about this
Thanks Sorin . Have a nice weekend. :- )
Very nice solution. It is a good compromise.
It works, thanks for sharing.
No one is happy like Sorin when he said “ Finally Friday” 😀

Varry good work .
About to send my replacement laptop screen back as it was going faint then brighter. When I plugged in the charger the screen stopped flickering. thought the screen was bad! thanks!
nice video professor
Love this bro
love your videos i wish i could be your student and learn this from you
You are amazing!!!! Lots of love from Bangladesh ❤💙❤💙❤💙
Epic Sir. Just Epic! 😎
I love your videos
it was perfect . keep it up . thnx
Yeyyyyyyyyy we are back 🙏🙏🙏
Video upload 1 hours a go and views 1.8k nice one sir thanks
That is NOT a hardware fault. It is a energy saving thing by intel. Its called "Intel Display Power Saving". Disable it !!! The voltage goes up and down because the driver is dimming the whole time.
Hy bro my lcd panel is white laptop lcd is white please help for repaire tgis
Bro you a lifesaver idk how to thank you browsed through 100s of videos but what worked out was a comment Keep it up my G
Couldn't find mine
Es correcto, la mía se solucionó de esa forma, desactivando el ahorro de energía en el menú de configuración.
Im curious if he tried with a live os usb drive and the laptop didnt flicker why didnt he tried to uninstall the display drivers only.
I had this problem many times. In all my case the Intel graphics driver was faulty.
it is called "Intel Display Power Saving". Disable it and you will be fine. The voltage goes up and down because the driver is dimming the whole time.
@@nebuzstar Yes, or you can install an older driver version. And it is recommended to disable the automatic driver update, otherwise the error may come back with the next update :)
Yep, same here
But wouldn't that also affect it being on the charger too
@@andythomas7931 The problem is due to the difference between battery and power supply mode.
Thanks it is working now
great job
THANKS BOSS ... NICE VIDEOS... FOR ME
Thank you Sorin for an interesting information that you share
Your amazing!
Awesome tenx for d technic,it will be usefull in some other time with same problem, i was cautious, what was that thing you paste first b4 solder applying jumper wire?
flux paste ;)
If you can't see it before Windows it's really a driver issue especially if it's a laptop with a higher OS then he came with (now with 10 and probably came with 7 or something else)
But nice to know more hardware secrets
Clearly you can see..... No Sorin, sadly often we can't because your mind is working at a much higher level in the background and we can't read every essence of your historical understanding. Zero criticism intended whatsoever, grateful for the wisdom as ever. Would have rathered a fix but understand your method and bravo, job done no problem. If only we could download our learning experiences onto an ssd and share them, dunno if it would be much of a swap here tho 😁
What if you use resistor on jumper to make the brightness at least 80% or something like that, can you try it?
excellent sir
Very good 👍
what was the liquid that you applied before soldering ? what is that thin wire called ? can i use a thin solder with a small bit to solder or will it fry the truck ? and i might lose display completely ?
great vid
But are you sure that, now that the client cannot drop the brightness with the keyboard itself, what about using third party software, or even Nvidia brightness control panel? i think that would work.
I have a client laptop that has Horizontal white lines, and some of black in the corners, also the resolution seems like a bit reduced at corners and also blurred with white.
is it that the ribbon cable damaged or something?
That was great!
as it started ok - and only began to flicker after drivers started to load, I would have guessed at a driver issue. Also, what happens when power options are set to turn off the screen?
Yes it loads up ok, and starts flickering when in windows. This could be the adaptive brightness causing an issue with the flickering.
AND NOW WE HAVE..... 23! WHAT!? HAHAHHA LOVE U SORIN
Hi Sorin! Isn't it dangerous to inject voltage directly into an output (PWM) of the Super-IO chip? Could that tension destroy the Super-IO over time? Thanks!
If you know what it should handle. You can stay in correct limits of that rail.
Like it bouncing around 11v it must be a 12v rail.
So only send a steady 11.8 or so
Had this problem on a few asus laptops but all the voltage was fine , replaced the screen and problem solved, this one he repaired could have been a driver fault or super io, But 23v could not be right
Nice one
Hi I have a dell xps 7390 and is randomly on the screen flickering even in bios , what do you think is wrong with? Thank you very much
Mr Sorin , Couldn't the vertical line on the screen can be from the main panel cable------> motherboard???
Can you do a screen repair on hp laptop 14-cf0012dx?
Wow nice fix
Hi sir, I have a problem with my slim acer x483 flickering from boot and won't stop flickering on battery or plugged. I dont know if its the backlight or need a jumper too. I noticed a lot of same issues with this model.
Thought we should not touch the screen board, my screen goes all vertical line after touching it. Why? Changed the screen cable still the same. It is the ribbon on the board problem?
my exact problem, lemme check this out
hi. iv got an asus x555lD laptop and the screen works but its like the back light is faulty as you can barley see the screen & when charger is plugged in it works like normal. Took it too an IT company and they said its the led within the LCD screen is this correct? if so how do i replace it?. as a new screen is like 120$. thanks
man you are great
Why would you not pop in an ssd with an os installed to see if its a software issue? And if someone breaks the screen in the future you have to do the job again.
I received a laptop with same issue, but I found out that in windows 10, when the power adaptor was disconnected, the brightness level automatically drops and cause this issue. I just updated the Intel graphics driver, and adjusted the brightness level to 100 on both with battery mode and charger. And it worked fine 😀
You can disable "Intel Display Power Saving". Then this fault will disappear.
@@nebuzstar I do it but not working.
Having face same problem but not find out proper suggestions.
The solution is very good. I was lucky because it was a software problem. On an Asus x54h laptop with hd7470m graphics card, Windows 10 put the latest video driver and when I set the brightness less than 100%, the backlight lights went out completely, and when I set brightness to 100% they were on the maximum so I couldn't watch to the monitor and the solution was to put an old but good video driver and to block the driver update in windows.
E foarte buna solutia. Eu am avut noroc pentru ca era o problema de soft. La un laptop Asus x54h cu placa grafica hd7470m Windows-ul 10 punea cel mai recent driver video si cand dadeam luminozitatea mai mica de 100%, ledurile backlight se stingeau complet, iar cand dadeam la 100% erau aprinse la maxim de nu ma puteam uita la monitor si solutia a fost sa pun un driver video vechi dar bun si sa blochez actualizarea driverului in windows.
where can i buy a microscope like yours? i really need one of these to work with. Thanls!!
hello, I have a similar flickering problem but I lose the image and the screen became white and grey. Any idea?
This Is a EDID mismatch problem! You can backup old (broken) screen EDID info and update the new screen firmware and it will work perfectly. Or like other people said, you can disable the brightness adjustment...
If only I understand what you are saying, I would be able to fix my laptop. I want to keep the brightness control function because I use it a lot
Top!!
this is called improvisation, the problem is not fixed where it should be. there is a problem with the system that saves the battery, if the maximum light on the monitor is from the battery, then the damaged battery is quickly consumed.
Hi, maybe my laptop has this same problem. How much does this job usuualy charge?
I have some type of problem with my laptop "Samsung RV511" can you please suggest the solution??
I want to know hp dv6-2000 series screen magnet position
I smile instantly 😊😄
I had this same problem 2 weeks ago on a toshiba laptop and it was fixed with a new battery.
interesting.
Hi, I m having problem with my laptop. The screen won't turn on, until I move the screen up and down. What is the problem?
Hello Sorin, you mentioned you can replace the board altogether. I have a Hp envy 13 aq10**** with a similar problem. I'd like to replace the whole LCD connector board. Where can I purchase it in the US?
No.. not possible without advanced factory tools. The lcd ribbon is connected / merged to both
And if a model has a removable board which most do not. Probably best to just buy lcd at that point
What are you going to do with 3080?
Wealth of knowledge and logical decisions...
My laptop overheated then screen starts to flicker freezes and everything. But screen is okay when i connect it to a monitor or a tv. is this a hardware issue?
I have a Toshiba Satellite Radius P55W-B5224 laptop whose screen flickers. I connected it to an external monitor with a HDMI cable and the display on the external monitor was perfect. I watched a movie for more than one hour non stop with charger connected. While the external monitor screen display was perfect, the laptop screen after flickering for a long time, became dark. So is it a software (Intel Graphics setting) or hardware (damaged/failed) laptop screen issue? I disconnected the touch screen cable, still flickering, pink some time green color flashes, unstable screen color changes continued. Viewer feedback as well as author's feedback is highly appreciated. All the vowels of the key board are out - not working; I am using an external keyboard. I have already tried to load the old display driver and tried. same issue. I have updated the display driver, same issue. Both times, the external monitor display was perfect. Thanks for reading.
Nice
the brightness control is very important
My personal laptop have a problem. Its work properly in battery mode. but when I plug in the charger backlight goes off. but laptop work properly. can you help me please ?
Hello coac why my hp laptop have charging light but can't power up , i have no battery
i am getting blank white screen.. Should I replace the screen?
FYI - Some older Toshiba laptops have a 15V power adapter. They don't work with 19V.
Leave those single-core oldies rest in peace :D
@@em0_tion still running my Tecra S11 with intel core i5 at 15V
@@marcellipovsky8222 Yeah, i have nothing against them as laptops, i was just always annoyed when i couldn't find such a wide inner diameter charger for them 15V oddballs :D Tecras are sure worth keeping, unlike most cheap Satellites, so kuddos on the great choice ;)
Same problem Lenovo b590..??? Please help..??
Hi sir I have a problem with my new lcd screen acer aspire one d270. I just replaced it but when I stared I waiting couple minutes then my lcd overheating can you help me sir.
I need help with my hp monitor, issue is half repeated image
This is not a hardware issue. Just uncheck the Intel Display Power Saving Technology option from Graphics Properties and the flickering issue is resolve.
Yes that is the reason why it is only when windows is booted and the intel driver is loaded, but not on bios or at bootup logo.
but it would have been a rather boring solution :)
Don't be stupid, for many cases like mine, it happens even on startup at bios
@@jacquesdupontd I don't think you understand the situation. Looks like you're the stupid one here. As you can see in this video, the problem occurs after the windows is loaded and not on bios during startup. That means it is a driver problem rather than a hardware issue. I fixed more than 10 laptops with the same issue like this due to the buggy Intel Display Driver. In your case, that sure is a hardware issue.
