    1) Check and post the voltages on CN1 (LVDS connector).

    2) Be sure that none of the series caps on the LVDS interconnect are not missing.

    3) Do you see a backlight on for the display panel ? If not, the display is not enabled or the backlight voltage is not high enough.

    Post the voltages on CN1 for at least:

    a) Pins 1&2 V_BLIGHT

    b) Pin 6 CCD_POWER

    c) Pin 7&8 +5V_LCD

    d) Pin 13 DISPON

    e) Pin 14 LCD_VADJ

    4) Is the display that you are testing a known good display? Is it the proper and compatible one for this logic board ? The schematic notes EDP and LVDS style of display can be supported by this design - which one do you have?

    Can you post the markings on your display ?
