Panel Type Check
There are 2 types combination of the LCD Panel/Prism Ass'y and the optical unit, named Type-L and Type-R.Since both have no compatibility, each type should be combined with the same type, and the specificparts should be used. If not, the poor optical characteristics may degrade the quality of a projected image. When replacing the LCD Panel/Prism Ass'y,you need to take "Panel Type Check and Setting" on the Electrical Adjustment. The gamma-characteristics is different between Type-L and Type-R LCD Panel/Prism Ass'y
