The problem is with the blue LCD panel being damaged by the lamp. Unfortunately the only way to repair this is to replace the optical engine. They do have rebuilds available now. The part number is UX23681DR (R is for rebuild) here is a source http://salestores.com/hitachiux236.html for $330.33 plus s/h and then who's going to install it? Labor is typically $200.
Remember this is a problem that is inherent with all rear projection LCD televisions, and it will happen again.
The way these sets work is the white light produced by rhe lamp is send into the optical engine and the three primary colors are separated with filters and mirrors. The red, green and the blue colors are directed to three small LCD panels that is controlled by the appropriate colors' section of the video signal. Then the three separate pictures are combined through a prism and with the use of lenses and mirrors the picture is displayed on the screen assembly.
The fact that we have a hard time seeing blue color, the engine has extra lenses to boost the blue. Hence the blue is always the first to be harmed, the rest will eventually fail. the blue panel basically blisters and stops the light from passing and as a result the red and green are the only colors that hit the screen and those two colors produce yellow.
