(2) Output the VDP TEST PATTERN signal correspond to the
Max value.
Read the white coordinates and communicate 3 line with
ET7050 IC through measurement equipment of optics.
Adjust screen coordinates data to adjust the color uniformity of
max point.
ADJUSTMENT INSTRUCTIONS
At this time, make sure that deviation is +5~-5% and standard
is color coordinate of center.
(3) Output the VDP TEST PATTERN signal correspond to the
MID value.
Read the white coordinates and communicate 3 line with
ET7050 IC through measurement equipment of optics.
Adjust screen coordinates data to adjust the color uniformity of
mid point.
At this time, make sure that deviation is +5~-5% and standard
is color coordinate of center.
(4) Output the VDP TEST PATTERN signal correspond to the
MIN value.
Read the white coordinate and communicate with ET7050 IC
through measurement equipment of optics.
Adjust screen coordinates data to adjust the color uniformity of
miner point.
At this time, make sure that deviation is +5~-5% and standard
is color coordinate of center.
(5) White the miner, middle, maximum data for each point to con-
front to each MICOM address.
9. Brightness Adjustment of Main/Sub
Screen
Operate this adjustment when the brightness of Main/Sub screen
is different.
(1) Receive signal(RF 06Ch.) on the Main/Sub screen in the twin
picture.
(2) Confirms picture probably is the normal.
(3) Check the "US06CH" with naked eyes in 06Ch. pattern and if
there is difference, adjust like this.
- The field and the letters are distinguished.
(4) Adjusting Main screen
1) Select the 6. CONTRAST by pressing "ADJ" key on the
remote control for adjustment.
2) Select the Contrast(m) of adjustment item using CH +/- key
and revises using VOL +/- key.
(5) Adjusting Sub screen
1) Select the 6. CONTRAST by pressing "ADJ" key on the
remote control for adjustment.
2) Select the Contrast(s) of adjustment item using CH +/- key
and revises using VOL +/- key.
* Ask for repairs when the data value is changed over !2.
