Re: Asus UX31E missing backlight after replacing LCD
Hello all,
after searching for hours and finally found solution in my case with no voltage on pin 14 coming from U4501, will post it here, maybe it will help someone someday.
A partially removed (oblique ) LVDS connector on the LCD side was causing the simptom of no LCD backlight on an UX31A. The defect was caused by dropping the laptop.
Reinstalling the connector and replacing the adhesive tape that holds him in place fixed the issue.
What mislead me in the beginning was that U4501 was getting LCD_BACKOFF# signal
on pin 2 instead of LCD_BACKEN on pin 1. I think this was caused by backlight disabling when no load is sensed.
