41. HVSCAN : Setting up the scan direction while adjusting
unifomity - Do not adjust
42. Test Mode : uniformity adjustment test - Do not adjust
(4) Adjustment Sequence
1) Adjust the screen coordinates as shown below.
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.
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
confront to each MICOM address.
11.Brightness Adjustment of Main/Sub
screen
Operate this adjustment when the brightness of Main/Sub
screen is different.
(1) Receive RF 06Ch. to Main/Sub screen in twin picture.
(2) Let the screen clearly.
(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) Press the “IN Start” key on R/C for adjustment to select
VPC3230_Main.
2) Adjust to Luma Contrast of adjustment item with
Channel key. (initial value 32)
(5) Adjusting Sub screen
1) Press the “IN Start” key on R/C for adjustment to select
VPC3230_Sub.
2) Adjust to Lima Contrast of adjustment item with +/- key.
(initial value 32)
12. Lamp Replace
Use it when the Lamp time is ‘0’.
At the same time press the ‘OK’ key and ‘Mute’ key during 5
seconds.
Displaying the OSD as <Fig.8> , press the (
