In my previous Mits DLP, a 62" unit, I removed the front screen and carefully vacuumed out any dust inside the cabinet, then cleaned both the screen and the mirror. With the original bulb the picture went from dull to as brilliant as the first day I turned it on. That DLP eventually died and Mits gave me a new WD65737 for $200.00 shipped and set up after a lot of "negotiating" so I was fairly satisfied. But now that set is nearly 3 years old, the bulb has 6500+ hours on it and its starting to dim. Might need a bulb, maybe not?
What I'm curious about is whether you cleaned the mirror when you cleaned the "lens" material? How many hours are on your lamp, and are you back to really liking your picture?
