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 DVD/BD IN jack (J6001)
DVD/BD VIDEO IN jack (J6004)
Procedure:
1. "DVD" is selected by using [INPUT SELECTOR] jog.
2. Connect a color pattern generator to the COMPONENT
VIDEO DVD/BD IN jack (J6001) on the A_VIDEO board
and DVD/BD VIDEO IN jack (J6004) on the A_VIDEO board.
3. Input NTSC color bars signal from the color pattern generator.
4. Press the [POWER] button to turn off the main power
5. While pressing the [MEMORY/ENTER], [MUSIC] and
[DMPORT] buttons, press the [POWER] button to turn on the
main power. 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_V__
PAL : MW OK C_V__
(PAL input)
HD-V : MW OK C_V__
(HD input)
When "Check XXXX V-IN" is displayed, Video signal
necessary for the measurement while measuring it last time
was not detected and it became an error. Confirm 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

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. Confirm 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.
