ADJUSTMENT
SYNC Timing adjustment
●
Use the arbitrary monitor. (When using the arbitrary monitor,
use the “Parking OFF” since the screen is shown dark when
the source is the composite source.)
• Conditions
Video source : NAVI source and VIDEO source
Input video : NAVI and VIDEO signals
Operation mode : Parking OFF (to display OSD)
1. Use the Parking OFF to check if there is any space
at the edge of OSD. When AV1 is entered in the
composite signal.
2. Change each source.
3. Check that there are no jitter noises on the OSD.
4. If the jitter noises are observed, fi ne-adjust by turning
VR201 (X14-982) to the position where the jitter noise
is removed while observing the screen.
5. After turning VR201, re-check the timing with VSEL.

COLOR adjustment
●
• Conditions
Video source : NTSC composite video signal (AV-INI)
Input video : Color bar
Operation mode : Test Mode
• Adjustment
Adjust color with the remote controller by touching AUTO
Adjust, CHROMA FNC, and COLOR in this sequence
(AUTO Adjust → CHROMA FNC → COLOR) on the test
mode screen.
* To shift to the test mode, press the [Reset] key to start
the system while pressing the [MODE] and [VOL UP] keys
at the same time ([MODE] + [VOLUP]). Refer to KVT-
719DVD Service Manual (B53-0507-00) for the details of
the test mode.
1. Connect the adjustment connector pin. (Surface A)
Trigger with the composite or G signal and adjust color
as shown below while monitoring G signal.
The fi gure shown below is the output wave form of R, G,
and B colors.
2. Set the default values for COLOR register. (Default
value: 5C)
3. Shift to the COLOR adjustment screen and fi ne-adjust
the COLOR register.
Adjust the register by changing the COLOR value with
the UP/DOWN on the remote controller such that the
amplitude of one horizontal becomes constant.
Adjust the register so that the level of the K part is fl at.
4. After adjustment, press the fi nal [selection] key.
Color of OSD on the screen turns purple when the KEY
is pressed.
Then press the [end] key and when “Write OK” is
shown the adjustment is complete.
