RANGE
Vertical Setup Time. Delays the vertical sync to solve the jitter of OSD and TTX .
Check OSD while varying 96 111 step by step and an 1H line moves at two points.
If the value is set at the first point or second point, an OSD jitter may happen. Also,
if the value is set between the first and second points, a TTX jitter may happen.
So, the value of VSU should be set after giving some magines (three steps).
96~111
For example, OSD moves as much as 1H-line when changing data 98 to 99 and 106 to 107,
respectively.
At this time, VSU should be set to 110 by allowing for the margin of three steps
(If the value within 99 to 106 is set, a jitter may happens in TTX mode.)
Short for Q-CRT HORIZNOTAL EAST WEST, data used only for Q-CRT MODEL.
In NORMAL mode, the horizontal picture size is within 5 5.5.
-30~30
In Q mode, the horizontal picture size is within 6.5 7. This H QEW function sets the gap
between horizontal picture size in NORMAL mode and horizontal picture size in Q mode.
Corrects the vertical linearity in Zoom mode of P-SIZE. The data differs according to CRT
-30~30
(see data above)
Corrects the vertical linearity in 16:9 mode of P-SIZE. The data differs according to CRT
-30~30
(see data above).
Horizontal blanking pulse duty determines the position of TTX and FBT determines
horizontal blanking pulse duty.
-30~30
Because FBT depends on model, this TTX H Shift allows the micom to set the start
position of pixel to prevent the TTX screen from being shifted.
Not Used
BG
Allows the sync slice level of sync separate block to be changed. This item corresponds the case
0~3
where a vertical bouncing happens according to signal conditions by area
(overmodulation, especially). 0: 100% 1: 90% 2: 75% 3: 60%
0~20
Sets the level of melody volume in Picture ON. Differently controlled according to buyer and area.
Short for Auto Kined Bias, a function that maintains uniformity in brightness and white balance by
automatically correcting the variance of brightness and white balance according to temperature
ON/OFF
and characteristics of AMP in the CRT drive. It is designed to be turned ON/OFF so that the AKB
line can't be seen at top when a DY of lower deflection sensitivity is used
TTX mode has two different types; List and FLOF. When swtiching into the TTX mode, this function
ON/OFF
determines which type has priorty.
