Asus laptop, no backlight - actually a screen repair 

That's what I thought too, and it's lucky already that the screen allows the backlight on with one group not turning on... On my laptop that I tried to replaced LED's, if one group is not getting power, the backlight goes on for 2 seconds and then shut off!

hello SiE kindly elaborate

@@rbaamo7194 You can even see this, for example at. 34:14 3 LED lights - 1 not - 3 lights - 1 not etc.

yes

@@kztech1319 Hello sir . . is it possible to disassemble a paper LED panel and then reassemble it and get it to work as before . . I mean I would like to remove few paper sheets in there. . THanku

@@electronicsrepairschool won't you end up with a darker spot on the screen?

I too believe that's what caused the issue.

One of the videos that had that sort of error was one where the push button had something between it that was conducting, so the person would turn on the laptop and then it would switch its self off, because from the processors point of view it was like a person was holding down the switch, which turns it off. Since that video I always think its worth testing the push buttons, pretty sure you could do with it contunity mode to make sure its not in contact. I will say thought it would also be worth testing it with the resistance meter also because it may be that what ever material was inbetween the switch could have higher resistance than 10ohms so the contunity meter wouldn't pick it up.

@@Ghost572 That's very interesting. I've also seen somewhere a bad capacitor causing this kind of issue. I don't recall where I saw it, though...

did you find an answer? i'd like to know too

LOL Great father's teaching: "Do what I say, not what I do"

and then unpplugs and plugs it back like 100 times and completes the job by blowing 500 degrees on the keyboard. I love this man, best channel on you tube

+1. Futhermore, 1 of each 4 LEDs became disconnected. Maybe the fix was not as perfect as supposed...

Did you fix it?

@@MathijsGroothuis Yes, I did, I took a shorcut & checked the back of the screen & this was it.

i know, like how i said in the end of the video, i reworked the screen again
