Voltage Adjustment
Setting :
DIMMER selector (S701) : HIGH
BRIGHT dial (RV702) : Max. (light)
VOL dial (RV301) : Max.
Procedure :
1. Input the color bar (chroma off) signal from NTSC color bar
generator and display on the monitor screen.
2. Connect the digital voltmeter to CL66 on the monitor main
board.
3. Adjust RV401 (+5V) so that the digital voltmeter reads 5±0.1 V
DC.
4. Connect the digital voltmeter to CL86 on the monitor main
board.
5. Adjust RV601 (+9V) so that the digital voltmeter reads 8.5±0.1 V
DC.
Connection points : Monitor main board Refer to page 5.
Alignment points : Monitor main board Refer to page 5.
RGB Adjustment
Procedure :
1. Input the color bar (chroma off) signal from NTSC color bar
generator and display on the monitor screen.
2. Connect the digital voltmeter to CL151 on the monitor main
board.
3. Adjust RV213 (OFFSET) so that the digital voltmeter reads
2.3±0.1 V DC.
4. Connect the oscilloscope to CL42 on the monitor main board.
5. Adjust RV212 (COM CUT) so that the lower black level is
6.2±0.05 V DC.
6. Adjust RV208 (COM DRIVE) so that the upper 100% white
level is 9.2±0.05 V DC.
7. Repeat steps 5 & 6 until the items in the standards are satisfied.
8. Connect the oscilloscope to CL41 of the monitor main board.
9. Adjust RV207 (R DRIVE) so that the lower black level is
6.2±0.05 V DC.
10. Adjust RV202 (R CUT) so that the upper 100% white level is
9.2±0.05 V DC.
11. Repeat steps 9 & 10 until the items in the standards are satisfied.
12. Connect the oscilloscope to CL43 of the monitor main board.
13. Adjust RV209 (B DRIVE) so that the upper 100% white level
is 6.1±0.05 V DC.
14. Adjust RV204 (B CUT) so that the upper 100% white level is
9.1±0.05 V DC.
15. Repeat steps 13 & 14 until the items in the standards are satisfied.

Procedure :
1. Connect the oscilloscope to CL44 on the monitor main board.
2. Adjust RV210 (V COM AMP) & RV211 (V COM BIAS) so
that the output waveform is within the standards.
3. Repeat step 2 until the standards are satisfied.

NTSC Adjustment
Procedure :
1. Input the color bar signal from NTSC color bar generator on
the AV selector board.
2. Connect the frequency counter to TP61 (SC OUT).
3. Confirm reading the frequency counter is 3.579545 MHz.
4. Connect the oscilloscope to CN3 !£ pin (B OUT).
5. Adjust RV1 (Y.C ADJ) so that white peak (100% white) is
1.00 Vp-p.
6. Adjust RV2 (HUE ADJ) and RV3 (COL ADJ) so that amplitude
of each color is same (A=B=C=D).
PAL Adjustment
Procedure :
1. Input the color bar signal from PAL color bar generator on the
AV selector board.
2. Connect the frequency counter to TP61 (SC OUT).
3. Confirm reading the frequency counter is 4.433619 MHz.
4. Connect the digital voltmeter to IC10 !¢ pin (DLA BIAS).
5. Adjust RV5 (DLA BIA ADJ) so that reading the digital voltmeter
is 2.3 V.
6. Adjust RV1 (Y.C ADJ) so that white peak (100% white) is
1.00 Vp-p.
