Hi, What diode?? Have you tried connecting an external monitor the the laptop and check if there is a display on it when the laptop has booted into Windows? When the laptop is on, try shining a torch at an angle close to the laptop screen and check if you can detect any images. They will be very faint if they are there. If you can see images you have a backlight problem.
