VIDEO CALIBRATION ADJUSTMENT
Adjustment to decide the standard of the video input signal.
Note: After replacing D-VIDEO board, or after "SUPER RESET" of the
special menu mode is executed, perform this adjustment.
Connection:
color pattern
generator
color bars 100%
A-VIDEO board COMPONENT VIDEO ASSIGNABLE
(INPUT ONLY) IN 2 jack (J6002)
A-VIDEO board DVD VIDEO IN jack (J6201)
S-VIDEO board EXT VIDEO IN jack (J6904)
Procedure:
1. "DVD" is selected by using [INPUT SELECTOR] dial.
2. Connect a color pattern generator to the COMPONENT VID-
EO ASSIGNABLE (INPUT ONLY) IN 2 jack (J6002) on the
A-VIDEO board, DVD VIDEO IN jack (J6201) on the A-VID-
EO board and EXT VIDEO IN jack (J6904) on the S-VIDEO
board.
3. Input NTSC color bars signal from the color pattern genera-
tor.
4. Enter the special menu mode referring to the "SPECIAL
MENU MODE" (refer to page 23) of the test mode.
5. Press the [M][m] button on the remote commander to select the
"V.CALIBRATION START?", and press the [ENTER] button
on the remote commander. It enters the test mode, and display
as below.
V.CALIBRATION START? y NTSC : MW--_____
(PAL input) PAL : MW--_____
(HD input) HD-V : MW--_____
6. In state of step 5, press the [MEMORY/ENTER] button. The
adjustment is automatically completed, and result is written in
the EEPROM, and display as below.
(NTSC input)
NTSC : MW OK C_VEZ
(PAL input)
PAL : MW OK C_VEZ
(HD input)
HD-V : MW OK C_VEZ
When "Check XXXX V-IN" is displayed, Video signal neces-
sary for the measurement while measuring it last time was not
detected and it became an error. Confi rm the input of the video
of the terminal connection etc., and measure the [MEMORY/
ENTER] button again pressing.
7. Input PAL color bars signal from the color pattern generator.
8. Perform step 4 to 6.
9. Input HD color bars signal (720p or 1080p) from the color pat-
tern generator.
10. Perform step 4 to 6.
11. When all the adjustments end, display as below.

Procedure:
1. Turn on the set.
2. Input the following signal from signal generator to FM antenna
input directly.
Carrier frequency: A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)
Note: Use 75 ohm coaxial cable to connect signal generator and the set.
You cannot use video cable for checking.
Use signal generator whose output impedance is 75 ohm.
3. Set to FM tuner function and scan the input FM signal with
automatic scanning.
4. Confi rm that input frequency of A, B and C are detected and
automatic scanning stops.
When the station signal is received in good condition, automatic
scanning stops.
