3. C-Trap Adjustment
Purpose:
To get minimum leakage of the color signal
carrier.
Symptom of Misadjustment:
If C-Trap Adjustment is
incorrect, stripes will appear on the screen.
Note:
J219 (B-Out)--- Main CBA
1. Connect Oscilloscope to J219.
2. Input a color bar signal from RF input.
Enter the Service mode. (See page 1-6-9.)
3. Press [0] button on the remote control unit and
select C-TRAP Mode.
4. Press [P+/P-] buttons on the remote control unit so
that the carrier leakage B-Out (4.43MHz) value
becomes minimum on the oscilloscope.
5. Turn the power off and on again.
4. How to measure the standard
V-ENV value of Digital Studio
Picture Control
Purpose:
To set the recording condition appropriate
for the recording tape.
Symptom of Misadjustment:
Recording or playing
back picture quality may fall. The picture will be tinted.
1. Insert a new tape (type: TDK 180) for the DSPC
alignment into the TV/VCR.
2. Input the black raster signal from the video input
jack (VIDEO-IN).
3. Enter the Service Mode. (See page 1-6-9.)
4. To enter the DSPC mode, press [1] button on the
remote control unit. Recording starts automatically
and “DSPC” appears on the display.
5. Recording continues for 10 seconds in SP mode.
After that, recording starts for 10 seconds in LP
mode.
6. The tape is rewinded to the recording start point.
7. The unit enters the play mode automatically and
the V-ENV levels of each SP and LP modes are
memorized into the EEPROM.
8. "OK" appears on the screen with blueback for 5
seconds, the unit enters the stop mode, and is
gone out from the factory mode.
9. If SYNC. and CTL are none, "NG" appears on the
screen with blueback for 5 seconds, the unit ejects
the cassette and is gone out from the factory mode.
Or, also when the V-ENV level in either of the SP
and LP mode is written, "NG" appears on the
screen with blueback for 5 seconds, the unit ejects
the cassette and is gone out from the factory model
