3. Power supply
3.1 Setup the AC I/P at 264 VAC and 90VAC , and power board provide
two DC Output
1.The DC output voltage is 24V
±
1V DC for Inverter and Scaler
board Measured point between pin3(+24V) and pin6(GND) at
item 1001 of scaler board
2.The DC output voltage is 16V
±
1 V DC for Scaler and Audio
board Measured point between pin1(+16V) and pin6(GND) at
item 1001 of scaler board
3.2 Any adjustment is not needed.
4. PC mode Display Adjustment
4.1 Display quality adjustment
Use timing mode as describe in 2.2, and use the POPO (pixel on
pixel off) pattern to adjust the clock until no stripe and adjust the
phase until clear picture.
Adjust all pre-load 12 modes, but ignore the wave interference on
non-60 Hz modes.
4.2 WHITE-D adjustment (B)
4.2.1 At factory mode apply 1360X768 @60Hz mode with 32 gray pattern.
Set smart picture at "Normal" , and Brightness to 50% and Contrast
to 50%.
Set AUTO-COLOR function for auto ADC offset and gain setup.
4.2.2 Apply full white pattern , adjust the Cool, Normal & Warm SCALER
GAIN RG B to reach W/D and luminance in factory mode.(See fig.1)
1. Check (X, Y) co-ordinates as below :
Table 4.2.2.1: Reading with Minolta CA-110.
2. Check the gray level color poor & noise condition and chromaticity
Note: 1. Use Minolta CA-110 for color coordinates and luminance
check.
2.Set Light Senor off before W-D adjustment.
3.Luminance> 400 cd/m

in the center of the screen at
6500(NORAML)color and PC Brightness control; Contrast
control at 100%
4.Set smart picture at normal ,brightness &contrast to 50%
after
alignment.
5.Set Light senor off after Light senor check.
4.3 Check the digital interface cable (B)
Check the 32 gray level color poor & noise condition.
