I can purchase a Mitsu WS-65413 two years old for $400 from a friend. The protoctor screen is gone and the ridged screen has a small crack in it and some scratches. This was from getting it down the basement. The parts are $375 from Mitsu delivered to me. A) Can I replace these screens myself? B) Is it worth it for this TV? The TV seems to work fine mechanically and I got the manual to see that it comes apart in two pieces to move. They didn't know that and moved the TV as a whole. Thus the scrapes and scratches. I do not think I "need" the protector screen. What is involved with replacing the ridged screen and taping the two inside screens together??
