10-step gray scale

3-5. VCOM-DC Adjustment

1. Preparation

• AC adaptor or voltage regulator
• Photo sensor / photo sensor amplifier (C2719)/Low-Pass filter)
• Digital oscilloscope

2. Adjustment procedure

(1) Turn POWER on while pressing DISP key and MENU button simultaneously
(2) Quickly press keys in the order of FLASH key, FLASH key and MENU key.
(3) Select / Execute 50PERCENT GRAY.
(4) Monitor the photo sensor amplifier output via a low-pass filter of cutoff frequency 60Hz.

Monitoring the oscilloscope screen, adjust VR321 to minimize 60Hz ripple waveform.

3. Notes

Perform the adjustment after you replaced the LCD display module or L-PCB Assy.

4. Connection diagram / block diagram
