(use a 10 to 1 probe unless otherwise instructed.)
• PAL color bar generator
• DC power supply
• Digital voltmeter
• XT-993V (Hideaway unit)
• Frequency counter
Equipment Connections
Make the test equipment connections as shown below (unless
instructed otherwise) and perform the alignment.
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 PAL color bar gen-
erator 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

RGB Adjustment
Procedure :
1. Input the color bar (chroma off) signal from PAL color bar gen-
erator 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.
