Put a bright flashlight sideways when powering on. If you see the colors of the display and, well, the image, you will need a new display, as the backlight driver (the chip in the display) may have gone bad. Try taking the device apart ([guide|128909]) and unplugging and replugging the display. If this doesn't help, you may need a screen replacement.

Try taking the device apart ([guide|128909] don't need to follow unplugging everything else and de-soldering the battery) and unplugging and replugging the display.
