AKBOFF
(1)
: AKB ON/OFF switch (Set to ON mode at power-on.)
0 = AKB ON
1 = AKB OFF IK clamp, IK S/H and reference pulse fixed to OFF.
R, G and B cut-off adjustment at AKB OFF performed by voltage
applied to Pins 19 (RSH), 21 (GSH) and 23 (BSH), respectively.
V-SIZE
(6)
(2)
: Vertical amplitude adjustment (V sawtooth wave gain control)
0H = –14%
1FH = 0%
3FH = +14%
Vertical picture size decreases.
Amplitude: 1.15Vp-p, center DC : 3V (when V-ASPECT = 1FH)
Vertical picture size increases.
V-COMP
: Compensation amount setting for vertical high voltage fluctuation (V sawtooth
wave gain control)
0H = 0%
V sawtooth wave amplitude compensation amount when 1V is
applied with respect to when 9V is applied of VCOMP (Pin 26)
V sawtooth wave amplitude compensation amount when 1V is
applied with respect to when 9V is applied of VCOMP (Pin 26)
3H = –5%
V-POSITION
AFC MODE
(6)
(2)
: Vertical position adjustment (V sawtooth wave DC bias control)
0H = –0.09V
1FH = 0V
Picture position drops, VDRIVE+ output DC Down
Center DC: 3V
2FH = +0.09V Picture position rises, VDRIVE+ output DC Up
: AFC loop gain control (PLL between Hsync and Hvco)
0H = H free run mode
1H = Small gain
2H = Medium gain
3H = Large gain
S-CORR
V-LIN
(4)
(4)
: Vertical S correction amount adjustment (V sawtooth wave secondary component
gain control)
0H = Secondary component amplitude by adding sawtooth wave is 0
FH = Secondary component amplitude by adding sawtooth wave is Maximum
: Vertical linearity adjustment (Gain control for V sawtooth wave secondary
component)
0H = 85% (Bottom/top of picture) Top of picture expanded; bottom of picture
compressed.
7H = 100% (Bottom/top of picture)
FH = 115% (Bottom/top of picture) Top of picture compressed; bottom of
picture expanded.
H-SIZE
(6)
(2)
: Horizontal amplitude adjustment (V parabola wave DC bias control)
0H = –0.5V
1FH = 0V
3FH = +0.5V
Horizontal picture size decreases, EWDRIVE output DC Down.
Amplitude: 0.58Vp-p, center DC: 4V (when V-ASPECT = 2FH)
Horizontal picture size increases, EWDRIVE output DC Up
REF-POSI
: Reference pulse timing setting
0H = (From VTIM rise) Rch: 22H, Gch: 23H, Bch: 24H
1H = (From VTIM rise) Rch: 20H, Gch: 21H, Bch: 22H
2H = (From VTIM rise) Rch: 18H, Gch: 19H, Bch: 20H
3H = (From VTIM rise) Rch: 16H, Gch: 17H, Bch: 18H
