XV-Z1E/A CONTROLLING THE TOTAL OPERATING HOURS OF THE LAMP The following control is carried out when the lamp has been used for 1900 hours and 2000 hours. 1. After 1900-hour use When the power is turned on, "LAMP" appears in the on-screen display for about 1 minute (flashing in yellow) and the lamp LED indicator lights up in red. When the 1,900-hour point comes up during use of the unit, the "LAMP" display starts flashing in yellow on the screen for 1 minute at the very 1,900-hour point.
XV-Z1E/A RESETTING THE LAMP OPERATING HOUR COUNTER The unit is designed to keep its power off when the lamp has been used for 1900 and 2000 hours. This is to protect the lamp fixture.

XV-Z1E/A CONVERGENCE AND FOCUS ADJUSTMENT » Start the convergence and focus adjustments with the top cabinet and the signal shield removed but the power on. Use the remote control gun 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.
XV-Z1E/A Note : 1 The eccentric cam is used for convergence adjustment. This means that the cam’s turning and the linear movement are not always uniform. 2 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.
