Use the remote control to adjust the image. Take the following procedures. 1. Focusing the projection lens (A) Replacing all the 3 LCD panels 1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus. 2. Replace the panels with new ones.
I XG-XV1 E/A Notes : @ The eccentric cam is used for convergence adjustment. This means that the cam’s turning and the linear movement are not always uniform. 0 This model is not equipped with the LCD image adjustment mechanism. This is because the dichroic prism is used for image formation. When the LCD panels all get into the best focus, the images are almost completely converged.
