I have this pretty old DMM that developed LCD issues; a splotch in the middle of the screen was making the digit underneath pretty hard to read.... And replacement LCD is not easy to come by. So I took it apart anyway and tried to get the reflector off in one piece, but it just shredded... And it turned out the blotch was in the polarizing film somehow too, so it needed to come off which was a tedious task.... Once I got it off and tracked down some film on amazon, I cut it to size (making sure to get the correct angle 90 degrees to the front polarizer), it worked pretty good! My wife gave me some shiny paper to use as backing which worked a lot better than foil, but plain white paper worked pretty good too. I didn't bother with trying to seal everything back together since it looked fine to me as it was (but I might go back to plain white paper!) Had to do some futzing with zebra connector and clean the pcb contacts along the way as well. Here's a couple of pics.
