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.

Hi,
I have a new Asus Zenbook S16, Model UM5606. Unfortunately, the keyboard backlight is too bright, even on the lowest setting. I have explored several ways now:
- kindly ask Asus for an adjustment - they basically told me to STFU and get lost
It is not possible, they say. Of course.
- tint the keycaps from behind - I have already tried that - it is kind of a last resort
- try to find out, how it is done, look at schematics - this is, where we are at.
- maybe get the BIOS modified somehow? This would be the best option but I do not know a lot about...02-24-2025, 02:03 AM -

Hi everyone, hope all is well. I have run into a problem where my backlight screen is no longer working.
The original screen was beginning to show signs of faultiness. I believe it was part of the inverter board that was going bad. The backlight for the screen was still functional at this point. Well one night as I was tinkering with the laptop, my idiot self forgot to disconnect the battery from the motherboard. I attempted to reconnect the EDP cable onto the motherboard, and as you might guess, I saw a nice spark from the cable and the port. Don't worry, I'm still kicking myself... -
Background:- Hisense 65H6570G stopped working and I root caused to a burnt out LED in the backlight. (For anyone interested the power light pattern when the backlight has gone is 1) two long flashes, 2) a very short third flash, then 3) back to solid red )
- I replaced all 6 of the backlight LED strips with these replacements: amazon
- The TV worked again perfectly for ~2 weeks.
- After that 2 weeks the colors became "inverted". The TV powers on and shows the boot screen in correct colors initially (aqua hisense logo on black background, pic on the left) but a few seconds after boot

Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM
