Re: Asus x555ld rev 3.1

Thi is the voltage detected on the pin on SCHOTTKY BAT54AW (UP)
The SCHOTTKY BAT54AW (BELOW).

Re: Asus x555ld rev 3.1

What's the voltage on all pins of this power switch?
Do you have image on the LCD?

[Raziel]

Re: Asus x555ld rev 3.1

I have the image on the LCD but no backlight because the pin 36 (INTERFACE CONNECTION MODULE PIN CONFIGURATION - CONNECTOR LVDS) don't have the sufficient voltage

This is a new picture.
Have you a Asus X555ld rev3.1 boardview schematic ?
Please.........

Re: Asus x555ld rev 3.1

Boardview available here: https://www.badcaps.net/forum/showpo...43&postcount=5

Check voltage on both pins of the resistor, check resistance to ground of pin 2 of the resistor, check resistance across pin 1 and 2 of the resistor.

This is a new picture. The green line should be 3v (on the scheme numeric, pin 36 BL ENABLE), instead it is 0.29v.

See up the new picture with control voltage, resistance to ground of pin 2 of the resistor and resistance across pin 1 and 2 of the resistor.

Thanks to everyone, I solved anyway.
Not as I wanted, but it works the same.

Hi, i have a problem with Asus x555ld ver. 3.1
The tension of 3V Backlight panel on/off in the pin 21 of Analogix ANX1121 is down.
Help please

that ic many time break

external works but internal no. BEWARE of connecting good nice panel. it damage fuse and controller. i break two panels before replace chip

Picture of Analogix 1121

Replace it. It always break down. But test LCD panel on another laptop. When this Dport->LVDS decoder breaks down in many times it destroy every LCD that is connected to it. it cost few bucks

By sn. this is your dump

Thnx bro!

Re: Asus x555ld rev 3.1

yes, i think onboard RAM ist problem
but do you know how i can disable onboard RAM for REV 3.1 ?

Sometimes the soldered RAM goes bad on asus boards.Whats your motherboard part number

I think I have the same problem with RAM, the onboard RAM and the added 4GB default ram heats up to 100 centigrade degrees when I disconnect the battery and power up the device using only the adapter. Again there were no LCD light; LCD did not power up only the power+HDD activity lights were lit.

Do I have to disable the on board RAM or I need to completely remove it by desoldering?

Any type of help is appreciated. Thank you.

Re: Asus x555ld rev 3.1

I had an oxidation and eventually a signal breakdown

Could you please tell us where this part was located on K555ln i5 5200u Laptop motherboard? Was your problem with the on-board RAM after all?
