Convergence Adjustment Mode

The Convergence mode is used to perform raster ge- ometry correction and convergence adjustments.

These adjustments must be made in both the SD (NTSC 480i) and HD (1080i) modes.

Note: Before activating the Convergence mode, turn “Video Mute” Off. The internal crosshatch pattern will not be displayed with “Video Mute” On, only a blue background is displayed.

Convergence Mode Activation

1.Press MENU-0-3-5-9

2.When the Convergence Mode is activated, this display appears on a Green Crosshatch. See Figure 2-5.

Figure 2-5: Convergence Mode

Selecting the HD or SD Mode

1.Select the Signal Source before entering the Convergence Mode, either an NTSC or HD source.

2.Enter the Convergence Mode

If the signal source is NTSC, the SD mode is activated.

If the signal source is HD, the HD mode is activated.

3.Activating the HD mode when no HD signal is available

Press the “DEVICE” button.

Use the “UP-DOWN-RIGHT-LEFT” direction buttons to select ANT-DTV, then press “ENTER”.

Press “MENU-0-3-9-5” in sequence to activate the Coarse Green HD Conver- gence mode.

Convergence Mode Functions

In the Convergence Mode there are three main Func- tions (Categories).

Pressing “6” activates CONV MISC

Pressing “5” activates COARSE CONV

Pressing “4” activates FINE CONV

CONV MISC (Press 6)

This mode is used to preset data values controlling the Convergence Generator, and to perform the HV Regulation adjustment.

1)Use the VIDEO button to select an item.

2)Use the ADJUST buttons to change data.

NOTE: When Item “1 HVOL” is selected the screen goes black except for the data display. This occurs since a black screen is required when making the HV Regulation adjustment.

COARSE CONV (Press 5)

There are four Sub Functions in the Coarse mode,

COARSE GREEN, COARSE RED, COARSE BLUE and DF.

COARSE GREEN .... used to make Coarse Raster Geometry Adjustments.

COARSE RED ... used to make Coarse Red Convergence Adjustments.

COARSE BLUE ... used to make Coarse Blue Convergence Adjustments.

DF ... used to preset data values controlling the Dynamic Beam Focus circuit drive signal.
