Re: Asus UX31E missing backlight after replacing LCD
Hi. Already sent you a private message, but here's the explanation where to find the L4518.
Remove motherboard from laptop chassis. Find TOP side of motherboard (should be marked on PCB near USB connector).
L4518 (together with another component) is located between the USB connector and screw hole near USB conn. L4518 is the closest one to the screw hole....

Re: Asus UX31E missing backlight after replacing LCD
Ok. Finally got the time to check the main board...
Found out that the ferrite L4518 at the +3VS_LCD line was burned. Replaced it and everything works again. No other damages found.Leave a comment:

Re: Asus UX31E missing backlight after replacing LCD
Thanks atsio. Will do that.
Schematic seems to be for UX31A, hopefully it's the same from LCD backlight perspective. Any idea where this U4501 is located?Leave a comment:

Asus UX31E missing backlight after replacing LCD
Hi there,
Bumped to a typical (stupid) problem while replacing LCD panel in my laptop...
Didn't remember to disconnect battery before the job
and now I have a laptop with functional LCD without backlight. Patient is UX31E from Asus.
I know there has been similar problems with other Asus models, but couldn't find fix for this model.
Anybody have a clue what components to check (couldn't find any schemas/layout)?
Any help appreciated! -
