A. Adjustment for AFT voltage and AGC
voltage of IF channel in TV
1 IF AFT adjustment
Enter factory menu, set IF VCO to 1, or press ”INPUT”, “2”, “5”, “8”, “1” to enter VCO adjustment mode, disconnect J2, adjust LZ100 to value 2.5V of TP5(B face), then wed J2.
B. IF AGC adjustment
Input 184.25MHz RF signal of 60DBuv from RF terminal for china, and 175.25MHz for America, adjust RZ133 to value 2V of TP1(B face) and there should be no obvious snowy picture. Increase the signal to 90DBVuv and it should be display normally and no obvious noise.
C. White balance adjustment
1 HDMI white balance correct
a. Input VG-848 signal to HDMI: TIMING854(800*600/60Hz) 8 level gray scale of PAT920, adjust the balance with CA210.
b. Enter COLOR TEMP sub menu and select color temperature of standard(9300K)
c. Fixed B OFF, adjust R OFF, G OFF to let the color coordinate of the second level be
283,297(CPT panel) and the brightness be 3nit ~10nit or so; Fixed B GAIN, adjust R GAIN, G GAIN to let the color coordinate of the seventh level be 283,297(CPT panel). Repeat adjust R OFF, G OFF, R GAIN and G GAIN, until the two color coordinate of the level gray scale be 283,297(CPT panel).
2. VGA/YPbPr white balance check and correct
a. Connect VG-848 signal of VGA to VGA terminal and input TIMING854(800*600/60HZ) (PATTERN:CROSS), and auto adjust to full screen then input PAT948 black/white signal, enter submenu of ADC ADJ, select AUTOTUNE and wait for OK display. Input PAT920(8 gray levels), check if the white balance is normal, if not, set ALL COLOR to 0 and fine adjust.
b. connect VG-848 signal of YPbPr to YPbPr terminal and input TIMING972(1080I/60Hz) PAT908 color bar(include back/white bar), enter submenu of ADC ADJ, select AUTOTUNE and wait for OK displaly. Input PAT920(8 gray levels), check if the white balance is normal, if not, set ALL COLOR to 0 and fine adjust according the method of 3.3.2
c. Input AV signal(PM5518, 8 gray levels PAL for China and NTSC for America) to VIDEO 1 terminal, check if the white balance is normal, if not, set ALL COLOR to 0 and fine adjust Note: it can’t set back to 1 once ALL COLOR changes to 0.
