Alignment and Adjustments
5-3 Liquid Crystal Screen Center Adjustment
After replacing with the new liquid crystal panel, make sure that the liquid crystal screen center is
aligned with the screen center. If they are not aligned, make the following adjustments:
1. Using a hexagonal wrench, loosen the two screws that secure the liquid crystal panel.
Note: Loosen the screws just until the panel can move easily.
2. Using two fingers, lift the liquid crystal upward. (The screen moves downward.)
3. When moving the liquid crystal panel towards the left, the screen moves right (and vice versa).
5. Repeat adjustments 2~4 until the screen center is aligned vertically and horizontally.
6. Using a hexagonal wrench, refasten the two screws.
