This set has 3 screens---the outer one is really only for glare--clear plexigalss--no longer available from Sony.
SCREEN, PROTECTION (CONTRAST)Outer one is (Contrast) the other two inner ones are showing as available and about 180 each.
You would have to either have someone dismantle or do it yourself---most of these sets you have to remove all three screens from the rear of the set---then remove the outer contrast one if it is scratched or cracked--
If you get it out and measure it: It is possible you may be able to find a company who can cut you a plexi-glass piece to replace it with--lots of work to do this and you have to use extreme care when you remove the two inner screens--easy to damage them---Usually the inner two are taped along all the edges to keep dust etc from getting between them and the front one is a short distance forward of them.
The front protective screen is really only there for glare and to protect the inner screens from damage---I have seen people who had a cracked outer one just dismantle and remove that one---put the others back and use the set that way---have to be careful as the inner screens are easy to scratch or damage with the outer one removed.
Also---I have seen several where someone removed the outer one and got a piece of plexi glass big enough to put on the outside of the front of the set---secured all around the edges with velcro--does not look as good as the original but prevents glare and protects the inner screens.
