Alignment and Adjustments
❈ When adjusting the screen, it is better for two people to work together.
On person should direct the picture position while the other person looks
at the screen.
❈ The movement direction of the board and the picture are opposite.
- When the board is lifted upward, the screen descends down.
- When it is tilted to the left, the screen tilts to the right.
❈ When the picture adjustment is completed:
First, tighten the two screws on the left of the DMD board
and then slowly tighten the one screw on the bottom right.
Be careful not to touch the board while screwing.
(When using an electric-powered screwdriver, be careful that
the torque is not too high.)
1-40
Turn on the TV to send signals.
Then, adjust the screen position,
by holding both of the upper corners
of the DMD board.
