5. Backlight Consumption Current Adjustment
(VF-106 board)
Adjust the luminance and color temperature of the back light.
If these are not correct, the image will be brighter or darker than
normal.
Note 1: If the oscilloscope is connected to other instruments,
disconnect them, and check that the oscilloscope is not
touching other instruments.
Note 2: Don’t connect the 680 Ω resistor to pin !ª of CN6202 (EVF
VG).
Adjusting method:
1) Adjust the power supply voltage so that the Pin 1, 2 voltage
(ACV UNREG) of DD-91 board CN3701 becomes 6.0 ± 0.1Vdc.
2) Set data: 01 to page: 1, address: 00.
3) Input the following data to page: D, addresses: E8 to ED.
6. White Balance Adjustment (VF-106 board)
Adjust to the proper white balance.
If it is not correct. the color reproducibility of the LCD panel will be
poor.
