It appears as though you need to subscribe to get to the tweaks section. My subscription has run out so I no longer have access. If you have a Mitsu set, it is the Pelican of Home Theater. Great guys, very helpful and loaded with information.

Anyway, the front screen of your tv should come off fairly easily. If you take that off, take a look at the inside of the tv. I believe the 'mirror' is mylar, probably not something you want to touch, but the lenses and the screen can probably be cleaned with lense cleaner and the right soft cloth (not a paper towel). Probably the same set-up you would use to clean a camera lense.
