My bet is that it's a defect in the microdevices themselves. I'm far from an expert but it would seem they are the workhorses here. Perhaps Sony used organic alignment layers mentioned in this How LCoS works article http://electronics.howstuffworks.com/lcos3.htm
Considering they recommended waiting for it to "warm up" eliminates any other possible cause IMHO. 2006 models will have new microdevices which I'm also betting will resolve this issue, time will tell.
From the bottom to the top, here are the components of an LCoS microdevice and what they do:
Printed circuit board (PCB): carries instructions and electricity from the television to the device
Silicon (a chip or sensor): controls the liquid crystal, generally with one transistor per pixel, using data from the television's pixel drivers
Reflective coating: reflects light to create a picture
Liquid crystal: controls the amount of light that reaches and leaves the reflective coating
Alignment layer: keeps the liquid crystals properly aligned so they can direct the light accurately
Transparent electrode: completes the circuit with the silicon and the liquid crystal
Glass cover: Protects and seals the system
The exact materials and configurations differ from manufacturer to manufacturer. Some use nematic liquid crystals and others use ferroelectric crystals. Some use organic alignment layers, which can break down through use and exposure to the high-intensity light from the lamp.
Others use photosensitive materials and light to control the impulses to the liquid crystal.
