- Enter the adjustment process mode.
- Select the item [VCOM ADJ] on the page 3/26 using the CH ▼/▲ keys on the remote controller.
- Press the Enter key to check that the adjustment pattern is displayed.
- Adjust the flicker in the middle of the screen to minimum using the VOL (+)/(-) keys on the remote controller.
- Press the Enter key to turn off the pattern.
- To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
