    Start with a known good LCD+cable as water easily gets in there.

        Must know if it is backlight problem or image. Check very carefully with a strong light as it is very difficult to see on these LCDs. I currently do not have the diagram, it may be available though.

            Fuse checked? What is the voltage on the backlight output? LCD connector not fried?
