Look at 7:45, under the filter you soldered.

[@jumulka1309]

That's what I saw, need a solder blob to make the connection

[@NorthridgeFix]

Good catch. I took out the board again and jumped the connection + new screen. Unfortunately it's still a no go.

Was thinking in the same line. Had to delete my comments after reading this and knowing that Alex did attend it.

"Long repairs" may not make business sense... but it sure makes for a great video! I loved this one!

[@joelmiller4459]

That repair was a ten minute fix...run a wire to one of the hot wires on the LCD connector

[@Swenser]

I second the idea. Just force 3.3v onto enable pin.

Alex, Try closing/jumping JP4501! Thank you for your videos.

[@user-tj4eo6ip8v]

You are right.

[@potatobuilds]

This

[@hansregli8678]

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.

[@MrEagleeye58]

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

[@petezd1]

I hate when i get a no fix computer in for repair, i feel that it defeated me! But on to the next repair.

[@mattnsac]

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.

[@shadowopsairman1583]

Pcbs are designed to fail now

[@grahamsatchwell4440]

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

[@soumyaranjanmoharana4804]

Enable with 3V3 from anywhere if it's a problem.

[@anisakid-kg3zn]

Excellent video. Great detective work.

[@husainhabib4789]

This was extensive and complex repair attempt. Despite diligence and smart work mechanics, a more deep rooted issue came to light. Despite the disappointing outcome, i like to see repairs that dont just have one facet to its mystery. How else would you learn and hone your skills? (rhetorical question)

[@Dwedit]

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.

[@atsimas]

This isn't for repair, it is for education. This amount of damage calls for replacing the board.

[@scarone10]

give a permanent signal to the pin. If it has to go to the trash, at least it still works :)

[@rittol2365]

Love your proffesionalism, definitely look up to it

[@davejones1226]

Just take 3.3v from anywhere.

[@NorthridgeFix]

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. .

[@obvious7777]

..but that could be considered 'dodgy'.

[@TC2290-wh5cb]

That's what a cowboy would do.

[@Ripara-Zione]

The question is: it's better a "dodgy" repair or a no repair?

[@Rubacava_]

A switch can be attached at worst. Better than thrashing whole laptop ​@@NorthridgeFix

[@JacobLara]

A video for all you haters that think Alex's videos are too 'easy' and 'short'....... great job bud

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.

nice!! video. liked and subscribed because of your attitude!! lol awesomeness. learned few things from you.

[@josephcondino2283]

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,,

[@ZaBnj]

JP4501 near the first missing inductor should be closed, you got an open line there sir,

[@DemiGod3]

isnt it possible to drive the backlight enable pin high to let it turn on? enable pins is normally a smaller volt above ground to tell the inverter to start, probably around 3v. and on some inverter circuit, the dim if at zero volts, it drives the backlight on constant at full bright.

[@kendoty2463]

. . . May be a data recovery . . . Also a screen, etc, may be hooked up to make set useable . . . 🎉 ❤ 😮

[@kmieciu2003]

What software do you use to view board diagrams?

FlexBV, or openboardview is the free one

I use boardviewer

[@rancillinmontgomery2480]

I have a asus gl503vd. Shorted gpu. Is it really shorted or does it just need reballing? Bad enough to burnout the mosfet and transitor on the battery.

[@OktaFierce]

Requires a carefully calibrated wire...

[@niels5207]

Is it inducter or resisror or both?

[@usamasaad9334]

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.

[@alaskanjade9951]

Great effort

[@kumin0312]

Put an led strip behind the screen... and connect it directly to the battery.. and add a switch to turn it on or off..😅

[@chox2001]

Great video as always

[@AaronJohnProduction]

Have you tried using a known good lcd again after attempting the fix on the motherboard ? Maybe it's an LCD fuse issue now

[@Myadr1an0]

Why dont you measure backlight enable signal while the laptop is on ? just to make sure...

[@AsylumSmash]

Could a thermal camera help potentially?

[@macoxygene]

What about the inverter ?

That would also be my first guess with those symptoms.

There are some board schematics software out there but usually you have to buy them and he's using one of them.

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.
