    Post the schematics (if available).

    Unable to locate the MBX 266 schematics in my database.

    Most likely the LCD panel is a LVDS interface. There should be a backlight pin on the display panel connector. That pin and voltage needs to be reviewed. Check for any damaged pins / dirty contacts / corrosion. Clean with alcohol which never hurts. Reseat and test again.
