If you have scratches on your LCD TV or any LCD screen just rub a little vaseline into it....clean the surface of the screen and then take some Vaseline and fill the scratch with it. Gently wipe off the excess Vaseline making sure not to wipe too hard so that you leave some inside the scratch. It fills the scratch up. It works because the optical density of Vaseline very closely matches the LCD face compared to air
We have tried this and it works, but obviously do anything with caution
