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)
