Nikon D40 plastic LCD window cover repair (also D40x, D60, and others)

Most, if not all, digital cameras have some sort of plastic cover on top of the LCD. The plastic cover protects and seals the LCD from damage. If the LCD cover gets hit hard enough it cracks. If your LCD underneath looks like someone spilled ink on it, then you’re out of luck, the LCD will need to be replaced as well.
