3. White Balance, Luminance adjustment:
A. Bias (Raster) adjustment:
(a) Set mode8 1024×768 @85Hz full white pattern(100% white field).
(b) To make the adjustment condition is under the Factory preset OSD menu.
Same as step 2-B.
(c) Warm up more than 20 minutes.
(d) Put the probe in the middle of screen, Brightness
set to maximum. Contrast set to
max. change to Raster pattern(No video)1024×768 @85Hz, set G-Bias
40,then adjust
B-Bias
, R-Bias and FBT screen VR, to make the color temperature x= 265
±10, y= 290 ± 10, Y=0.6±0.02FL
(e) Press up or down key to select cursor on 9300 icon and than press menu key for saved the
bias data to EEPROM.
B. 9300 and 6500 5500 color temperature window pattern(20% white field) adjustment:
(a) Set mode 1024×768 @ 85Hz Raster pattern.
(b) adjust Brightness , to make raster Luminance is 0.06 FL.
(c) Change mode to 1024×768 @ 85Hz window pattern(20% white field).put the probe in the
middle of screen ,Adjust G-Gain
, B-Gain , R-Gain , to make color
temperature x=283±10, y=297 ± 10, Y= 48±0.6FL.then save to 9300.(use up/down key
select cursor on 9300 icon and than press menu key)
(d) Adjust G-Gain
, B-Gain , R-Gain , to make color temperature x=313±10,
y=329± 10, Y= 48±0.6FL.then save to 6500.
(e) Adjust G-Gain
, B-Gain , R-Gain , to make color temperature x=333±10,
y=346± 10, Y= 48±0.6FL.then save to 5500.
C.Full white luminance(100% white field) for 9300:
(a) Set mode 1024×768 @ 85Hz full white field
(b) Adjust VR701 to the luminance at 33 ± 0.3FL.
D.Cut off adjustment:
(a) Set mode 1024×768 @85Hz Raster pattern.
(b) Adjust Brightness , to make Y= 0.06 FL.then return from factory OSD mode to user OSD
mode.
4. Focus Adjustment:
A. Set mode 1024×768 @85Hz with crosshatch pattern.
B. Then adjust focus VR1 to a fine vertical line.
C. Adjust focus VR2 to a fine horizontal line.
D. Repeat step B & C. and change to full text pattern double check focus uniformity.
