(272,278).
f) Fix G OFFSET, adjust R OFFSET, B OFFSET and let the color coordinate of the third scale be
(272,278).
g) When adjusting, please keep the color temperature of high light to be X=272±5, Y=278±5 and
the low light to be X=272±8, Y=278±8.
h) Move the cursor to “COPY ALL” and copy the data to the other channels.
i) Check if the color temperatures of NORMAL and WARM are up to the mustard (low light
acceptable error:±8, high light acceptable error:±5), if not, adjust R-GAIN/ B-GAIN/ R-OFF/
B-OFF.
j) Check the color temperature of COOL, NORMAL and WARM of other channels (ANALOGTV,
DVB-T, Video, YPbPr,VGA), if they are not up to the mustard then adjust and store the data
separately.
k) The reference of adjustment rule is below:
B gun: lower B gun to increase X, Y coordinate data, while raise B gun to decrease the data.
R gun: raise R gun to increase X coordinate data, while lower R gun to decrease the data; (R
gun adjustment will affect X and Lv slightly).
G gun: raise G gun to increase Y coordinate data, while lower G gun to decrease the data; (G
gun adjustment will affect Y and Lv greatly).
5. Performance check
5.1 TV function
Connect RF to the center signal source, enter Channel menu
→ auto search, check if there are
channels be skipped, check if the picture and speaker are normal.
5.2 AV/S-Video terminals
Input AV/S-Video signal, check if the picture and sound are normal.
5.3 YPbPr/YcbCr terminal
Input YUV signal (VG848 signal generator), separately input the YUV signals listed in table4 and
check if the display and sound are normal at any situation (power on, channel switch and format
convert, etc.)
