I have one of these TVs that's starting to show signs of failure of
the blue and green polarizers. There is a slight lack of blue from
most of the screen and there's a noticeable green cast to what should
be black. I took apart the light engine to clean the dust out and I
can see a slight burn on the blue polarizer. The green filter looks
ok, but I find it hard to believe this set originally had such poor
blacks (it's only 2.5 years old).

Has anyone had any luck replacing the polarizers in LCD projectors
like this? From what I've read, they aren't available from Zenith/LG.
Has anyone found a source for new polarizing material that could be
made to work? I assume the polarizers used in other types of LCDs
such as overhead projector panels, or laptop displays wouldn't be able
to take the heat. Has anyone tried it?
