I noticed a small scuff mark on my JVC 27" flat television screen and I am not sure how to get rid of it. I tried a cleaner designed for electronics including television and computer screens but was not able to get rid of it (it got rid of other things like fingerprints). It looks like a scuff mark the size of a small dot and would not come out no matter how hard I tried to rub it out. Is there anything else I can try? It's possible that the glass might be damaged but it's hard to tell. It bothers me mostly because it is a fairly new television set (only a couple of months old).
