I just restacked the screens on my Pioneer SD-533 using Michael TLV's instructions to get started (thanks Michael). But I am curious as to whether there is a reason for the order the screens are arranged in. From the inside out, the screens on my 533 are fresnel, lenticular, contrast (glare). When restacking screens to eliminate glare, typically the contrast screen is moved to the back of the stack, so the new order becomes contrast, fresnel, lenticular. But there are quite a few people who advocated completely removing the contrast screen, contending that putting it on the inside of the stack simply increases reflections inside the cabinet, causing halos, poor blacks and other undesirable effects. But the contrast screen provides most of the strength and rigidity for the stack and removing it increases the potential for bowing. This made me curious. As a compromise, could the contrast screen be placed between the fresnel and lenticular screens? That would make the screen order, from the inside out, fresnel, contrast, lenticular. The potential problem here is that I have heard that the fresnel and lenticular screens are designed to work together as a unit and the putting the contrast screen between them would degrade picture quality. If this is the case, then complete removal of the contrast screen would seem to be the better alternative. Any comments would be appreciated.
