T
he steps of debug during production
:
Manually adjustment of White Balance and ADC calibration:
1)
ADC calibration
Input dual 16 grey scale signal 1024*768/60Hz(Chroma2225 Pattern47,Timing38 or
Chroma2327 Pattern47, Timing14) from VGA socket
Input 8 color bar with 100% saturation(2327 Pattern37, Timing33 or BSG360A Timing79,
Pattern85), PAL system from Y,Pb,Pr socket.
Enter ADC item of Factory Menu, select the source which you are going to calibrate.
Then select AUTO TUNE and press Vol- button in remote control.
Note: First confirm the input signal pattern and format are correct. After
calibration, If the grey scale can not be distinguished, calibrate again until it
is distinguished.
Color Temperature adjustment.
Before adjustment you should confirm the color analyzer has been calibrated. During
the process, only AV1 Y,Pb,Pr,VGA source should be adjusted. We recommend you use
CA210 color analyzer(0 channel),because it is more accurate.
Connection of devices
:
1)
connect CON3 of Debug Board to CA210(input VGA signal to CON6 when adjust VGA
source. Connect CON5 of Debug Board to the set through VGA cable. Input
corresponding pattern required, then select GAIN AUTO,press Vol+ button of
remote control.
2)
Input 8 grey scale signal of 5418 from AV1/Y,Pb,Pr/VGA source. Point the optical
lens to the fourth brightest scale. Then enter Factory Menu and select WHITE
BALANCE page, select GAIN AUTO, press Vol+ button of remote control.
Note: In the process of adjustment, you can press MUTE button of remote control
to cancel.
