Sony Vaio no backlight

[MDY]

I'm fighting with this Sony Vaio PCG-6S3M with MBX-170. No scheme ... this is the worst.
Has picture, but the LEDs do not light at all ...

1. Try other screens and the screen is not
. Try another screen with cable this time and nor ...
According to the chip that manages the display LEDs, this display is not receiving 19V as most 3V screen but for the LEDs. It present in several 3V pins, but I miss some pin voltage 3V (enable or shine) and tI does not light the leds ... Without scheme is hard to check where I have to provide 3V pin to activate LEDs.

Any tips?

Note: I do not have datasheet of this screen to see where it receives the enable pin and brightness. The screen is LTD133EXBY

Hi,

thank you for your time and help. Conector is page 30, right? Conector what I plug to my screen has 35 pins. Here are more pins... I think is not similar to MBX170

From pictures I see of both boards (mbx-147 and mbx-170) I can count 44 pins on both.
