good theory Rocat.. i know the G5600nv from new, and can see the problem gradually become so much worse and the's nothing i can do about it.. its like there are something in the manufacturing process that make the tiny gap between the crystal and adhesive getting some reaction.
the positive mod G5600nv definately got some claudy haze, but it become much less noticeable when the positive lcd was fitted... it seem the dark surface of the negative LCD would pronounce the haze significantly.
