replaced.

If colour 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 colour irregularities.
4. Repeat the above steps 1 and 2 until there will be no colour irregularities. Now tighten up
the screws A and B.
5. Finally secure the lamp cover back in position.
