633 not working right

I have a 633 blue LCD, and it's not working right, I can install it correctly, I have it in the COM7, but I cannot make it to show anything.
If I plug the floppy conector, he stays with the LCD backlight off (but not the keyboard backlight) for a few seconds, and then, the backlight gets on. In the period that the backlight is off, the fans are running, and when the backlight gets on, the fans stop spinning. The LCD does not response to my backlight/contrast settings, what's going on with this module?

thanks
