This adjustment is needed when any of the optical parts of the optical mechanism has been replaced.
1. Disconnect the flat cables from all the LCD panels.
2. Light up the lamp.
3. Project a white-light image and check to see if there is any color tint in any direction. If any, use the M2, M4 and M5
adjusting levers.
4. Loosen the adjusting lever lock screws, make adjustments, and tighten up the lock screws.
Correcting color irregularities on white-only screen when replacing the lamp
If color irregularities are found at the right and left on a white-only screen after replacing the lamp, it is necessary to
readjust the optical axis of the new lamp. Take the following steps.
1. Open the lamp cover and loosen the screws A and B at the bottom of the lamp.
2. Using a screwdriver or the like, move the U-shaped groove at the window D in the arrow direction.
3. Temporarily fix the screws A and B, close the lamp cover, and check the white-only screen again for color
irregularities.
4. Repeat the above steps 1 and 2 until there will be no color irregularities. Now tighten up the screws A and B.
5. Finally secure the lamp cover back in position.
