1.Adjustment Conditions

Power supply voltage DC

Input the suitable signal for each adjustment.

It shifts to TEST MODE by pressing in order of [OUT] [OUT][IN] [IN]

[VOLUME-] [VOLUME [RETURN] [POSITION].

When in TEST MODE, the items can be changed by pressing

of joystick, and the values can be changed by pressing [VOLUME ] or

[VOLUME-]

2.LCD Adjustment

< Adjustment conditions >

In VIDEO MODE, input monochrome10 step signal from VIDEO IN. Go to TEST MODE and adjust in order of the following.

Adjust each video signal value by default value (COLOR/TINT/ BLACK:

CENTER, DIMMER: MAX, AUTO DIMMER: OFF ).

1 )

B - B Adjustment

Observe VG(CS1, pin 8 ) by Synchro - scope.

Adjust [RGB AMP] to become [4.0V P- P 0.1V] between Black - Black

voltage (V

B - B )

2) B - W Adjustment Observe VG(CS1, pin 8 ) by Synchro - scope.

Adjust [BRIGHT] to become [2.9V

voltage (V B- W ).

3) Red Adjustment

Observe VR(CS1, pin 7 ) by Synchro - scope.

Adjust [SUB R] to become [2.9V P- P 0.1V] between Black - White

voltage (V B- W ).

4) Blue Adjustment

Observe VB(CS1, pin 6 ) by Synchro - scope.

Adjust [SUB B] to become [2.9V

voltage (V B - W )

5) VCOM Adjustment

Observe VCOM(CS1, pin 9 ) by Synchro - scope.

Adjust [COM AMP] to become wave Form [4.0V P- P 0.1V]

The steps should be like figure 1 by the above - mentioned adjustment.
