Electrical H/V Center Adjustment

H/V center adjustment may be necessary if the optical
block is replaced. Unlike previous GW models H/V
center is adjusted by the Rook ICs on the C board.

Since the adjustment takes place at the end of the video
processing chain there is no need to adjust H/V center for
multiple Wide modes.

Use the below Service Items to adjust:

1 TG (Device)

VST_POS (for V center) Initial Data = 12

Adjust [1~25] Primary item for V center adjustment

First, try to adjust with VST_POS if you must change more than +13/-11 then start
to change with FMDVPOS
*If “VST_POS” is changed greater than these limits then there could be issues with
Gamma.

HST_POS (for H center) Initial Data = 261

17 FMD (Device)

FMDVPOS (Secondary Method for V center) Initial Data = 8

