How's this for stupidity! Deciding that I needed to see the improvement of picture quality and glare reduction on my Mits WS-48311 without the Diamond Shield I decided to remove it. Taking out my owners manual and carefully following the directions I attempted to remove it. In the final step - IT SNAPPED LIKE A TWIG!!! I'm sure it's my fault somehow, though I'm not sure how. Anyway, the reason for this post is two fold: 1)If you decide to remove you Diamond Shield, be very, very careful. 2) When it did snap, it left to my complete and utter shock, a 3-4 inch thin scuff mark on the lenticular screen. I was sure this ruined my screen. But to my amazement, even though you can clearly see it when the tv is off and you walk-up to the screen, you cannot see it when watching DVD's or tv. I have watched probably 10 DVD's since this horribly embarring incident, and I've tried my hardest to notice it and can't. I've walked up to the screen, I've moved around to different viewing distances and angles, and it just can't be noticed. Needless to say this stopped me from throwing myself in front of a bus. I guess my question is, will this scuff mark manifest itself in the future during viewing, or will it just stay invisable and be a reminder that I'm a goofball? Any input and/or ridicule is welcome.
