1#.2 White balance adjustment Insignia LC-37HV41 TV Service mode
1#.2.1 Before adjustment
Before adjustment, the unit should keep working for over 30 minutes to be in a stable status.
a) In VGA channel, input VESA800*600/60HZ chessboard signal(VG848 Timing 854, pat 914), enter user menu ADVANCE and perform AUTO to let picture display integrity, enter the factory
menu ADC Setting and perform ADC AUTO to do ADC correction.
b) In YPbPr channel, input 480i/60HZ 75%color bar and gray scale signal (VG848 Timing 968, PAT 918), enter the factory menu ADC Setting and perform ADC AUTO.
1#.2.2 Four groups white balance adjustments (HDMI and VGA)
Allowable error range is below:
a) 12000K: The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50) The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,+20) The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15)
b) 9300K: The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50) The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,
+20) The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15)
c) 6500K:
The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50)
The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,+20)
The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15) For BESTBUY, it needs to check if the white balance of 50IRE gray scale is up to the mustard at
9300K and 6500K (BBY channel of CA210).
3.2.2.1 ATV channel adjustment (same for AV, S-VIDEO)
Input 21-channel signal to the TV AIR, enter the factory menu “Color Temp”, set “Color Mode” to COOL, 11-gray scale will display, fixed G GAIN, adjust R GAIN, B GAIN to let the color coordinate of the ninth level be (272, 278); fixed G OFF, adjust R OFF, B OFF to let the color coordinate of the third level be (272, 278). Adjust R GAIN, B GAIN, R OFF and B OFF repeatedly until the value of the two levels gray-scale are (272, 278) then press MENU return to the previous menu or press SAVE TO EEPROM to store the value.
Check if the color temperature of NORMAL and WARM is up to the mustard, if not, adjust R-GAIN/B-GAIN/R-OFF/B-OFF till accord with the requirement.
1#.2.2.2 DTV channel adjustment (same for HDMI)
Input 26-channel signal to the TV AIR, enter the factory menu “Color Temp”, set “Color Mode” to COOL, 11-gray scale will display, fixed G GAIN, adjust R GAIN, B GAIN to let the color coordinate of the ninth level be (272, 278); fixed G OFF, adjust R OFF, B OFF to let the color coordinate of the third level be (272, 278) then press MENU return to the previous menu or press SAVE TO EEPROM
to store the value.
Check if the color temperature of NORMAL and WARM is up to the mustard, if not, adjust R GAIN/ B GAIN/R OFF/B OFF till accord with the requirement.
1#.2.2.3 YPbPr channel adjustment Insignia LC-37HV41 TV Service mode.
Input 1920*1080I/60Hz 8-level gray scale signal of VG848 to YPbPr, enter the factory menu “Color Temp”, set “Color Mode” to COOL, fixed G GAIN, adjust R GAIN, B GAIN to let the color coordinate
of the seventh level be (272, 278); fixed G OFF, adjust R OFF, B OFF to let the color coordinate of the second level be (272, 278). Adjust R GAIN, B GAIN, R OFF and B OFF repeatedly until the
value of the two levels gray-scale are (272, 278) then press MENU return to the previous menu or press SAVE TO EEPROM to store the value.
Check if the color temperature of NORMAL and WARM is up to the mustard, if not, adjust R GAIN/ B GAIN/R OFF/B OFF till accord with the requirement.
