Asus Laptop Black screen - No Backlight Repair using available boardview diagram.

[@rifaatmajadle603]

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.

[@atsimas]

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

[@Swenser]

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

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

[@ZAKARIARACHID-j2f]

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]

@@hansregli8678 Ya, customer still can use it in cripple mode.. Hoook up one of those portable HDMI monitors.

[@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)

[@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

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

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.

[@playharder1435]

I reflowed a gfx chip on an HP, with no screen, heated it up in circles, reassembled bare minimum and Voila! It works 😮 common problem on DV9000. The manuf. switched the solder type from durable to a cheaper tin-type solder, as the chip heats, cools, heats, etc, the weak solder actually separates contacts (under the chip). A rework (heating up) reestablishes contact.

[@scarone10]

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

[@grilledchickenwrap]

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

[@JKiefer]

Sorry for the noob question, but why does a faulty PCH chip render it a no-fix? Is it too complicated to install a new chip for it to be economical? Or is there a reason that a new chip wouldn't even work?

[@kanutpy]

there's normally no pch news on the market, most of them are old ones that's sellers from ch takes from donor boards and thats make very very hard tod know if its works, and to replace it takes a lot of work, so is no economical, I think maybe that pin of the pch in failure had and bad ball soldering, maybeee but no recomended, making a reflow fix te issue for some time, no warranty of that. Or maybe in this case is ver economical to swap mb and hopefully everithing's works fine

[@AsylumSmash]

Could a thermal camera help potentially?

[@lawrencecavens5760]

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.

[@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

[@vlatkosurlan545]

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.

[@ChanvibolPen]

How can we get all that diagram for to see how components work?

[@sam_farsi]

u tried your best alex ,, defenlty pch problem

[@alaskanjade9951]

Great effort

[@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.

[@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.

[@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

[@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.
