Question posted by erikhelpowl on March 25th, 2010

Are The Lcds In The Xp21n Serviceable?

I understand this projector has one or three LCD panels to produce the image. It seems like mine have gotten "faded" over the years, and show greys as bluish. Whites are still white, but parts of an image that are darker look too blue. The bulb has been replaced, and the image is brighter, but the color problem still remains.Are the LCDs in this projector serviceable by a moderately experienced electronics tech? What are their replacement part numbers?
