3.4 Video signal Gain/Offset Adjustment
(Auto adjustment)
- Execution of RF no signal during Heat Run over 30min
- Connect to the LCD TV SCART input terminal with Patten
Generator(MSPG-925FS)
- Convert INPUT MODE to S-Video or AV1.
- Connect RS-232C Communication Cable to the Auto
Adjustment Equipment and SET's upgrade Port
3.4.1 Low Gray Adjustment
- Apply Gray-Level(Model : 202 PAL_BDGH, pattern : 59)
signal by using Pattern Generator(MSPG-925FS)
- heck weather color-coordinates 23" & 26" & 32"AUO (x:
0.283, y:0.298, ±0.005), 32"LPL(x:0.280, y:0.290, ±0.005),
32"CMO(x:0.270, y:0.285, ±0.005), 26" AUO (x:0.280, y:
0.285, ±0.005) is operated by using CA-110 equipment
- If color-coordinates is not in Spec, adjust color-coordinates
23" & 26" & 32"AUO (x: 0.283, y:0.298, ±0.005), 32"LPL
(x:0.280, y:0.290, ±0.005), 32"CMO(x:0.270, y:0.285,
±0.005), 26" AUO (x:0.280, y:0.285, ±0.005) by adjusting
Red Offset, Blue Offset
3.4.2 White Balance Adjustment
- Apply 95% White (Model : 202 PAL_BDGH, pattern : 47,
luminance spec : 250cd/m^2 over) signal by using Patten
Generator(MSPG925FS)
- Check whether color-coordinates(x:0.283, y:0.298, ±0.005)
is operated by using CA-110 equipment
- If color-coordinates is not in Spec, adjust color-
coordinates(x:0.283, y:0.298, ±0.005) by adjusting Red
Gain, Blue Gain
- All adjustment takes color-coordinates with based on G,
changing R and B. If it is not adjusted, adjust with fixed B,
changing G and R.
3.5 Component signal Gain/Offset Adjustment
(Auto adjustment)
- Execution of RF no signal during Heat Run over 30min
- Connect to the LCD TV Component1 terminal with Patten
Generator(MSPG-925FS)
- Convert INPUT MODE to Component1.
- Connect RS-232C Communication Cable to the Auto
Adjustment Equipment and SET's upgrade Port
3.5.1 Low Gray Adjustment
- Apply Gray-Level(Model : 210 576i, pattern : 59) signal by
using Patten Generator(MSPG925FS)
- Check whether color-coordinates 23" & 26" & 32"AUO (x:
0.283, y:0.298, ±0.005), 32"LPL(x:0.280, y:0.290, ±0.005),
32"CMO(x:0.270, y:0.285, ±0.005), 26" AUO (x:0.280,
y:0.285, ±0.005) is operated by using CA-110 equipment
- If color-coordinates is not in Spec, adjust color-coordinates
23" & 26" & 32"AUO (x:0.283, y:0.298, ±0.005), 32"LPL
(x:0.280, y:0.290, ±0.005), 32"CMO(x:0.270, y:0.285,
±0.005) , 26" AUO (x:0.280, y:0.285, ±0.005) by adjusting
Red Offset, Blue Offset
3.5.2 White Balance Adjustment
- Apply 95% White(Model:210 576i, pattern : 47, luminance
spec : 250cd/m^2 over) signal by using Patten Generator
(MSPG925FS)
- Check whether color-coordinates(x:0.283, y:0.298,
±0.005) is operated by using CA-110 equipment
- If color-coordinates is not in Spec, adjust color-
coordinates(x: 0.283, y:0.298, ±0.005) by adjusting Red
Gain, Blue Gain
- All adjustment takes color-coordinates with based on G,
changing R and B. If it is not adjusted, adjust with fixed B,
changing G and R.
