Re: Asus UX31E missing backlight after replacing LCD
Hi, thank you for your reply.
I think I located the u4501. I marked it on the photo. Is that the one?
Pins 1,2,3,4 show 0V. Pin 5: 3.3V
Last time I just checked the continuuity (it was fine). I'll check the impedance tomorrow....

Re: Asus UX31E missing backlight after replacing LCD
Hi, I aslo have same problem with ux31a. A friend of mine replaced a faulty power jack for me. After that while assembling the laptop I connected the LCD strip with the battery plugged in. I've heard some cracking noise and now backlight is gone.
I showed the laptop to two different "laptop repair specialists", but it turned out they're not really that good. One told me that there's something wrong with the motherboard, but he doesnt know what (he checked all the fuses he said). The other said the led backlight...Last edited by dinsdale79; 09-20-2017, 12:04 PM.
