Well I fixed it. It seems it was just a loose connection. After disconnecting and reconnecting the display the backlight started working again.
The keyboard backlighting state can be toggled using fn+f5.
try linux and see if the screen is still readable after turning of backlight ( with sun behind the screen) . I bought that pixelqi screen and ubuntu allow to set the backlight to any level (after a few tweaks google will help).
