Look at 7:45, under the filter you soldered.
That's what I saw, need a solder blob to make the connection
Good catch. I took out the board again and jumped the connection + new screen. Unfortunately it's still a no go.
@@NorthridgeFixDoes it not have a backlight I.C chip?
Was thinking in the same line. Had to delete my comments after reading this and knowing that Alex did attend it.
@@NorthridgeFix Love your content and you sure do leave nothing out. :)
"Long repairs" may not make business sense... but it sure makes for a great video! I loved this one!
That repair was a ten minute fix...run a wire to one of the hot wires on the LCD connector
Ned a proper calib..........😂
😂😂😂😂 ask customer if he wants it sent to UK for dodgy calibrated fix 🤣🤣🤣
Def it needs proper calibrated wire
@@5nowChain5 🤣🤣
Needs a dodgy one.
Did any of you say dodgy?🤣
Alex, Try closing/jumping JP4501! Thank you for your videos.
You are right.
This
Right. Then you would have proof whether the PCH was really the problem. If yes, you could even think of adding a small switch outside. Cheapest solution, but if the customer loves his old notebook so much he could still use it.
give a permanent signal to the pin. If it has to go to the trash, at least it still works :)
I hate when i get a no fix computer in for repair, i feel that it defeated me! But on to the next repair.
He knows how to fix it, thats not a defeat. The defeat is when you cant determine cause of failure. Fact of the matter is that it will cost way more to replace that BGA than just putting in a known good mobo.
Pcbs are designed to fail now
I second the idea. Just force 3.3v onto enable pin.
Hi Alex see 5:50 you point it there most be a solder blob you can also see it at the bord foto that you found on internet
The first inductor you replace next to it there look like a missing cap that goes to a via going to other side of board that could be needed for voltage or complete circuit
Love your proffesionalism, definitely look up to it
I've had a problem with a Lid sensor not working correctly. Luckily, disabling screen from lid was a software thing on my PC, and can be stopped by disabling the lid driver.
Enable with 3V3 from anywhere if it's a problem.
This isn't for repair, it is for education. This amount of damage calls for replacing the board.
Alex ❤ great job from Amine Algeria
Great effort
Great video as always
Have you tried using a known good lcd again after attempting the fix on the motherboard ?
Maybe it's an LCD fuse issue now
The reaction when backlight enable PCH popped up on the boardview says it all 🙈
Could a thermal camera help potentially?
Is it inducter or resisror or both?
nice!! video. liked and subscribed because of your attitude!! lol awesomeness. learned few things from you.
What software do you use to view board diagrams?
FlexBV, or openboardview is the free one
I use boardviewer
When are you doing the collaboration video with Jayz2Cents? His latest video shows he's in dire need of your skills. 🤦
How can we get all that diagram for to see how components work?
love the videos
It's OK, we love Northridge No-Fix also.
A video for all you haters that think Alex's videos are too 'easy' and 'short'....... great job bud
u tried your best alex ,, defenlty pch problem
What is a PCH?
are you a wizard with a dragon
Awesome ✌🏻✌🏻✌🏻
Awesome
Anyone said Dodgy? maybe we need a proper calibrated PIZZA😎😎😎
. . . May be a data recovery . . . Also a screen, etc, may be hooked up to make set useable . . . 🎉 ❤ 😮
May I suggest to look at the connector on the screen side That part could also be damaged If I'm seeing the damage on the connector side thats on the board - OK I stand corrected - I Oopsed.
good day alex,, im your fan in you videos and i like your Job,, im a technichian too,, have you tried to fix the backlight with other Driver to make it light,, or this not worth it to do? or make customer Happy,,

Could you connect BKLT_EN to anything else suitable for this function?
When you probe pin 40 it was moving from the pad BTW
What about the inverter ?
That would also be my first guess with those symptoms.
Just take 3.3v from anywhere.
That's called a Mickey mouse Job. You won't be able to control brightness or turn display off anymore. Lid close will also break and have no effect on screen going off anymore. .
..but that could be considered 'dodgy'.
That's what a cowboy would do.
The question is:
it's better a "dodgy" repair or a no repair?
A switch can be attached at worst. Better than thrashing whole laptop @@NorthridgeFix
The software what board diagram software is that. Or is it an insider.
There are some board schematics software out there but usually you have to buy them and he's using one of them.
cam_3v powers the camera module. It's there cause it obviously must go through the screen connector because the camera is on the lid.
Requires a carefully calibrated wire...
PCH also known as the MB's chipset?
yes, same thing
Put an led strip behind the screen... and connect it directly to the battery.. and add a switch to turn it on or off..😅
Hi friend, I'm looking for the board view of the Laptop Asus Rog Strix G16 - G614J, I can't find it on the internet, could you send it to me? I'm grateful
Big boss is your uncle (brother of your mother)? I was raised by my uncle(Kaare) and aunt(Emilie - "Milla", sister of my mother) and called my uncle "Kaarefar", "far" means father in norwegian.
Why dont you measure backlight enable signal while the laptop is on ? just to make sure...
backlight=19v or12v batry and DIMsignal 3.3v and ENLED 3.3V TEST DYNAMIQUE
❤
maybe a mod to bypass pch? like a separate switch
Make brige 3.3 dim and 3.3 enabled 😊
Hi 👋 i have Dell laptop E6440 and i want to install hard drive SSD SATA for install windows but not accepted and i install HDD sata accepted to install windows i don't know what happened on my PC please help me
I rcvd a mobile which has same issue , i have removed the connector and replacing it solved the problem. You did tried everything but did not worked on connector. Maybe the issue is connecter.
Do you guys think ordering a motherboard from aliexpress for my asus tuf is a bad idea?
Depends on the seller. I ordered a Ryzen 5700x3d from there without issues. Much cheaper than local.
Ive actually had really good luck with Ali, if you're ok with waiting a month for the part it's great. I wouldnt order things with mechanical parts like a GPU, cooler, things that can be broken in shipping, but other stuff I think is totally fine.
@@ChairmanMeow1 GPUs arrive fine if well packed ,no issues so far
@@DukeofEarl thanks for reply
@@Arachnoid_of_the_underverse what kind of gpus ? laptop chips or desktop gpus
you are amazing have a kit kat break
Cello!😊
Just do data recovery since he shipped it from Canada.
Best option is to make it into a desktop
Maybe there's a blown fuse.
I’m sure y’all tried turning up the brightness right … right … ???
AFAIK only Apple's brightness turns fully OFF on lowest setting. I haven't had a generic one do it yet.
👍👌👍
Im starting to think Asus laptops are a bad idea lol
Here we rehot the pch some time its works😂
I think it's the LCD
This why no Asus laptops for me. HP has more support I think.
Cam is for webcam power
The screen of my asus laptop flickers when i move the hinges. Did Alex rule this out with his testing? Maybe the laptop thinks its lid is closed.
You probably have problem with lcd cable.
that is an issue with the cable or the connections.
@@infi2723 Yep, one or another. 👍 From my experience can be both of them but in most cases it will be cable because of constant bending at the fold.
look in the bios. if its a gamming laptop with 2gpus it can be gpu related. turn of fgpu integrated in the cpu and see if the backlight works again
Laptops don't exist anymore, they are notebooks due to how crappy the cooling systems are.
Sines of flux and high temperature of air station. Someone trying to reflow something.
