4:3 VERTICAL AMPLITUDE ADJUSTMENT:
ADJUST 1 4 = 4 : 3 Vertical Amplitude
Enter a PAL B/G test pattern via RF. Change vertical slope till horizontal black lines on both the upper and lower part of the test
pattern become very close to the upper and lower horizontal sides of picture tube and nearly about to disappear. Check and
readjust VERTICAL AMPLITUDE item if the adjustment becomes improper after some other geometric adjustments are done.
4:3 S-CORRECTION ADJUSTMENT:
ADJUST 1 5 = 4 : 3 S-Correction
Enter a PAL B/G circle test pattern via RF. Change S-correction till the middle part of the circle is as round as possible.
4:3 VERTICAL SHIFT ADJUSTMENT:
ADJUST 1 6 = 4 : 3 Vertical Shift
Enter a PAL B/G test pattern via RF. Change Vertical Shift till the test pattern is vertically centred, i.e. horizontal line at the centre
pattern is in equal distance both to upper and lower side of the picture tube. Check and readjust Vertical Shift item if the
adjustment becomes improper after some other geometric adjustments are done.
4:3 EW WIDTH ADJUSTMENT (only for 1100 picture tubes):
ADJUST 1 7 = 4 : 3 EW Width
Enter a PAL B/G test pattern via RF. Change EW Width till the vertical black and white bars on both left and right side of the
pattern exactly disappear.
4:3 EW PARABOLA WIDTH ADJUSTMENT (only for 1100 picture tubes):
ADJUST 1 8 = 4 : 3 EW Parabola Width
Enter a PAL B/G test pattern via RF. Change EW Parabola Width till vertical lines close to the both sides of the picture frame
become parallel to vertical sides of picture tube. Check and readjust EW Parabola Width item if the adjustment becomes improper
after some other geometric adjustments are done.
4:3 EW CORNER PARABOLA ADJUSTMENT (only for 1100 picture tubes):
ADJUST 1 9 = 4 : 3 EW Corner Parabola
Enter a PAL B/G test pattern via RF. Change EW Corner Parabola till vertical lines at the comers of both sides of picture frame
become vertical and parallel to vertical comer sides of picture tube. Check and readjust EW Comer Parabola item if the
adjustment becomes improper after some other geometric adjustments are done.
4:3 EW TRAPEZIUM ADJUSTMENT (only for 1100 picture tubes):
ADJUST 20 = 4 : 3 EW Trapezium
Enter a PAL B/G test pattern via RF. Change EW Trapezium till vertical lines, especially lines at the sides of the picture frame
became parallel to the both sides of picture tube as close as possible. Check and readjust EW Trapezium item if the adjustment
becomes improper after some other geometric adjustments are done.
16:9 HORIZONTAL SHIFT ADJUSTMENT:
ADJUST 21 = 1 6 : 9 Horizontal Shift
Enter a RED PURITY test pattern via RF.Change horizontal shift till the picture is horizontally centred. Check whether this
adjustment is correct after completing Service Mode Adjustment.
16:9 VERTICAL SLOPE ADJUSTMENT:
ADJUST 22 = 1 6 : 9 Vertical Slope
Enter a CROSS-HATCH B/G test pattern via RF. Change vertical slope till the size of squares on both the upper and lower part of
test pattern become equal to the squares laying on the vertical centre of the test pattern. Check and readjust VERTICAL SLOPE
item if the adjustment becomes improper after some other geometric adjustments are done.
16:9 VERTICAL AMPLITUDE ADJUSTMENT:
ADJUST 23 = 1 6 : 9 Vertical Amplitude
Enter a PAL B/G test pattern via RF. Change vertical slope till horizontal black lines on both the upper and lower part of the test
pattern become very close to the upper and lower horizontal sides of picture tube and nearly about to disappear. Check and
readjust VERTICAL AMPLITUDE item if the adjustment becomes improper after some other geometric adjustments are done.
16:9 S-CORRECTION ADJUSTMENT:
ADJUST 24 = 1 6 : 9 S-Correction
Enter a PAL B/G circle test pattern via RF. Change S-correction till the middle part of the circle is as round as possible.
16:9 VERTICAL SHIFT ADJUSTMENT:
ADJUST 25 = 1 6 : 9 Vertical Shift
Enter a PAL B/G test pattern via RF. Change Vertical Shift till the test pattern is vertically centred, i.e. horizontal line at the
centre pattern is in equal distance both to upper and lower side of the picture tube. Check and readjust Vertical Shift item if the
adjustment becomes improper after some other geometric adjustments are done.
16:9 EW WIDTH ADJUSTMENT (only for 1100 picture tubes):
ADJUST 26 = 1 6 : 9 EW Width
Enter a PAL B/G test pattern via RF. Change EW Width till the vertical black and white bars on both left and right side of the
pattern exactly disappear.
16:9 EW PARABOLA WIDTH ADJUSTMENT (only for 1100 picture tubes):
ADJUST 27 = 1 6 : 9 EW Parabola Width
Enter a PAL B/G test pattern via RF. Change EW Parabola Width till vertical lines close to the both sides of the picture frame
become parallel to vertical sides of picture tube. Check and readjust EW Parabola Width item if the adjustment becomes
improper after some other geometric adjustments are done.
