We have had a few people look at this unit. They bolth said the optical engine is bad. I wanted to get a second opinion. I have done a master reset of everything, cleaned the lense.... routine noob stuff. Could someone help me.. I will post a picture of the problem, its difficult to describe. If you have any information, it would be helpful such as link to a service manual that has parts diagram, information on what caused this, is it woth the price to fix..... The distortion only ocurs when the prjector displays dark colors. With a white background, you dont notice anything.
