DEBUG
BOARD
During production the Debug Board will be used to upgrading software, adjust White Balance.
During production the Debug Board will be used to upgrading software, adjust White Balance.
The function of the board is transfer TTL Voltage to 232
Voltage. 12V DC power supply should be provided through ON1/CON2.
The
steps of debug during production
Manual 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 cannot 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.

SMPS schematic
Block
Display panel
1. Check the inverter voltage 24V if supply for Panel,also view the panel have
backlight.
If have backlight,it shows that have inverter voltage supply.
2.
Check if have voltage of Vcc-panel for CMO panel. LG-PHILIPS L32OW 12V. Some
other small size panel is 3.3V.
3.Test
waveform of LVDS if OK, LVDS OK but no display, replace the panel.
Attention:
Do not remove the LVDS connector when the TV working or contact U300 only
time,to avoid shock U300.
