balance adjustment menu; adjust the third and seventh levels using white
balance. Select 6500k of “mode”, adjustment offset_R, offset_G and offset_B, let
the color coordinate of the third level be 308 and 316 and its brightness be
16nit more or less. Adjust gain_R, gain_G and gain_B, let the color coordinate
of seventh level be 308 and 316. Adjustment offset_R, offset_G, offset_B,
gain_R, gain_G and gain_B repeatedly until the value of the two levels
gray-scale be 308 and 316. Select 9300k of “mode”, adjustment offset_R,offset_G
and offset_B,let the color coordinate of the third level be 285 and 290 and its
brightness be 16nit more or less. Adjust gain_R,gain_G and gain_B, let the
color coordinate of seventh level be 285 and 290.

according to its product standard.
white balance adjustment of TV channel
Input AV signal (PM5518, NTSC system, 8 level gray-scale signal), enter
adjustment menu of white balance, adjust the third level and seventh level
using white balance. Adjust offset_R, offset_G and offset_B to let color
coordinate of the third level be 270 and 275 and its brightness be about 21nit.
fixate gain_B to 128, adjust gain_R, gain_G to color coordinate of the seventh
level be 280 and 280. adjust offset_R, offset_G,offset_B, gain_R and gain_G,
repeatedly using the same method until the value of the two levels gray-scale
be the specified value.
white balance adjustment YPbPr channel
input YpbPr signal of K-7253 to YPbPr-1 terminal, input TIME380(480i)
PATTERN471 8 level gray-scale signal, set the value of Hor-width to 23,
Ver-width to 5, S-bright to 120 and S-contrast to 140.Enter adjustment menu of
white balance, adjust the third level using white balancer. Adjust offset_R,
offset_G and offset_B, to let color coordinate of the third level be 270 and
275 and its brightness be about 15nit. Input 8 level gray-scale signal of
TIME392(480p), TIME394(720p) and TIME396(1080i) separately, repeat the above
operations to let color coordinate of the third level be 270 and 275 and its brightness
be about 15nit.

under window 2000/XP/NT)
FlashUpgrader (use
under window 98),
Based on the computer
features, set up the serial port (COM Port). Select corresponding serial port (if
it’s unable to FLASH WRITE, change to another port). Baud is selected to be
115200. Then select Reset Target After Download. Click FLASH pushbutton, it’s
ready to run. For other settings, please refer to the Fig. Above (already
defaulted by the system, normally no need to change). Switch on TV set the FLASH
