Adjusting these parameters to achieve white balance.
The adjustment must be performed on the signal " white box " .
5.2.2 Adjustment of AGC
Select the adjustable parameter "ADJUST 03" . This adjustment is recommended to remove the back of the housing. To the antenna input of the TV signal the level of 60 dBmV ( recommended frequency channel 12 , the recommended signal - " Color Bars " ) .
Digital voltmeter to measure the voltage at pin 1 of SLE . The voltage should be 3.7 V. If necessary, put it , adjusting the value of "ADJUST 03" .
Check the quality of the image signal at 90 dBmV.
5.2.3 Adjustment of AGC for SLE type PLL
"ADJUST 04" - for the drive with negative modulation .
"ADJUST 05" - for the drive with a positive modulation.
In these models is used.
5.2.4 Adjusting the delay luminance signal
"ADJUST 06" - delayed luminance signal system PAL.
"ADJUST 07" - delayed luminance signal for the system SECAM.
"ADJUST 08" - delayed luminance signal system NTSC.
"ADJUST 09" - delayed luminance signal to another system .
Adjustment "08 " and " 09" are not used.
The adjustment is made by a signal " color bars " system SECAM and PAL , respectively. It is necessary to achieve the most precise transitions ( borders) between the colors .
5.2.5 Adjust the vertical size (for kinescope 110 °)
"ADJUST 10 " - Adjusts the vertical size of picture tubes with a diagonal screen size of 63 and 70 cm Adjustment recommended for signal " UEIT " or " Net field."
5.2.6 Alignment of the image vertically (for picture tubes 110 °) "
ADJUST 11 " - centering the image vertically for picture tubes with a diagonal screen size of 63 and 70 cm Adjustment recommended for signal" UEIT "or" Net field. "
5.2.7 Alignment of the horizontal size for 4:3 aspect ratio
"ADJUST 12" - centering the horizontal size for 4:3 aspect ratio . Acts in cases where the image menu was set to " IMAGE SIZE" 4:3 . The adjustment is recommended for signal " UEIT " or " Net field"
"ADJUST 13" - linearity control vertical image to the aspect ratio of 4:3. Acts in cases where the image menu was set to " IMAGE SIZE" 4:3 . The adjustment is recommended for signal " UEIT " or " Net field."
