1. Adjustment item and a procedure
When the following components are replaced, adjust each item according to the table below.
1. 1. Lighting area adjustment
1. 1. 1. Confirmation of the lighting area
1. After replacing the DMD block or each Analysis block part,
check if any shade is visible in the DMD effective display area.
* Make the projection environment as dark as possible and project an all-white
and all-black pattern (internal test pattern) to conduct this check.
2. When the Lighting area interferes with the effective area, adjust the
Relay Lens Holder.
1. 1. 2. Adjustment procedure of the Lighting area
1. Select the "QUAD" of [LAMP SELECT], projection the "APL30%" of [TEST PATTERN].
2. Loosen the 2 fixed screw with a hexagon wrench (2.5mm).
3. 1) In advance, adjust the adjustment screw that lighting
area adjustment bracket clearance becomes 6mm.
2) Adjustment groove, must have adjusted to the center.
4. The "Adjustment screw" is adjustment the horizontal
direction of the Lighting area.
* The Lighting area moves to the rightward when turn
a screw in the clockwise.
5. The "Adjustment groove" is adjustment the vertical
direction of the Lighting area.
* The Lighting area moves to the under when turn
in the clockwise.
6. After adjustment completion, tighten two "fixed screw".
