As it appears from the images that the images are fine. The sanyo PLV-Z2 is a LCD projector. So basically it projects 3 R G and B lights to make the screen. Yes it is definately not a LAMP issue. Either dust could have accumulated on the R and G panels thus leading to these prominent BLUE patches or if the LCD panels are damaged, u have to get the G or R replaced.. try running a application like Displaymate from "http://www.majorgeeks.com/DisplayMate_d4189.html" and see which of the panels is exactly responsible for the problem. I think this should sort it out.
the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.
This was caused by a defect in the optical block of the TV. It will only get worse with time and the only way to fix it is to replace the whole optical block which is very expensive (over $1000 usually) and time consuming (you need to take the whole TV apart). However, since it was a defect, there was a class action lawsuit that caused Sony to extended the warranties for certain models on the optical block for parts and labor. Call Sony to see if your model was one of the ones they extended the warranty for.
There is a manual focus adjustment above and between the red and green gun, located in the front of the TV behind the panel; It is a small black box about 3X3" . This has all three adjustments .
