GENERAL INFORMATION
All adjustment are thoroughly checked and corrected
when the monitor leaves the factory, but sometimes
several adjustments may be required.
Adjustment should be following procedure and after
warming up for a minimum of 30 minutes.
• Alignment appliances and tools.
- IBM compatible PC.
- Programmable Signal Generator.
(eg. VG-819 made by Astrodesign Co.)
- EPROM or EEPROM with saved each mode data.
- Alignment Adaptor and Software.
- Digital Voltmeter.
- White Balance Meter.
- Luminance Meter.
- High-voltage Meter.
AUTOMATIC AND MANUAL DEGAUSSING
The degaussing coil is mounted around the CDT so that
automatic degaussing when turn on the monitor. But a
monitor is moved or faced in a different direction, become
poor color purity cause of CDT magnetized, then press
DEGAUSSING on the OSD menu.
ADJUSTMENT PROCEDURE & METHOD
- Install the cable for adjustment such as Figure 1and run
the alignment program on the DOS for IBM compatible PC.
- Set external Brightness and Contrast volume to max position.
1. Adjustment for B + Voltage.
1) Display cross hatch pattern at Mode 9.
2) Adjust C913 (+) voltage to 190V ± 0.2V with VR901.
2. Adjustment for High-Voltage.
1) Display cross hatch pattern at Mode 9.
2) Adjust CDT Anode voltage to 26kV ± 0.2kV with
VR701.
3. Adjustment for Horizontal Raster Center.
1) Display cross hatch pattern at Mode 9.
2) Adjust the Back Raster should be center of the
screen with SW701.
4. Adjustment for Factory Mode (Preset Mode).
1) Display cross hatch pattern at Mode 1.
2) Run alignment program for FS792E on the IBM
compatible PC.
ADJUSTMENT
3) EEPROM → ALL CLEAR → Y(Yes) command.
<Caution> Do not run this procedure unless the
EEPROM is changed. All data in EEPROM (mode
data and color data) will be erased.
4) COMMAND → PRESET START → Y(Yes)
command.
5) DIST. ADJ. → TILT & MISCI → TILT command.
Adjust TILT as arrow keys to be the best condition.
6) DIST. ADJ. → BALANCE DATA command.
7) Adjust balance of Pin-Balance and Parallelogram
correction as arrow keys to be the best condition.
8) DIST. ADJ. → FOS. ADJ command.
9) Adjust H-POSITION as arrow keys to center of the
screen.
10) Adjust H-SIZE as arrow keys to 310 ± 2mm.
11) Adjust V-POSITION as arrow keys to center of the
screen.
12) Adjust V-SIZE as arrow keys to 230 ± 2mm.
13) Adjust TRAPEZOID as arrow keys to be the best
condition.
14) Save of the Mode.
15) Display from Mode 2 to Mode 10 and repeat above
from number 8) to 14).
16) COMMAND → PRESET EXIT → Y (Yes) command.
5. Adjustment for White Balance and Luminance.
1) Set the White Balance Meter.
2) Press the DEGAUSSING on the OSD menu for
demagnetization of the CDT.
3) Display color 0,0 pattern at Mode 9.
4) COLOR ADJ. → LUMINANCE command of the
alignment program.
5) Set Bightness and Contrast to max position.
6) COLOR ADJ. → BIAS ADJ. command of the
alignment program.
7) Set the data of Sub-Brightness to 140.
8) Check whether blue color or not at R-BIAS and G-
BIAS to min position, B-BIAS to 120 (decimal)
position.If it's not blue color, the monitor must repair.
9) Adjust Screen control on the FBT to 0.15 ± 0.02FL
of the raster luminance.
10) Adjust R-BIAS and G-BIAS command to x=0.283 ±
0.005 and y=0.298 ± 0.005 on the White Balance
Meter with PC arrow keys.
11) Adjust Sub-Brightness command to 0.4 ± 0.05FL of
the raster luminance.
12) Display color 15,0 box pattern(70x70mm) at Mode 9.
13) DRIVE ADJ → No 1. command.
14) Set B-DRIVE to 100(decimal) position at DRIVE of
the alignment program.
