CONVERGENCE ADJUSTMENT MODE
- The Convergence mode is used to perform raster geometry correction, and convergence adjustments. These adjustments must be made in both the SD (NTSC) and HD modes.
CONVERGENCE MODE ACTIVATION
- Press MENU-0-1-5-9
- When the Convergence Mode is activated, the display below appears on a Green Crosshatch.
SELECTING HD OR SD MODE
Select the Signal Source before entering the Convergence
Mode, either an NTSC or HD source.
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.
ACTIVATING THE HD MODE WHEN NO HD SIGNAL IS AVAILABLE.
- Activate the Factory Option Menu (MENU-0-1-7-0)
- Use the “Adjust” keys to select “DTV Port” and use the “Enter” key to change the setting from “AUTO” to “1080i”.
- Exit the Option Menu (Press MENU twice)
- Select the DTV Inputs as the signal source (INPUT button)
- Activate the Convergence Mode ... the Convergence mode will be in the HD mode and the internal crosshatch is displayed.
AFTER ADJUSTING CONVERGENCE, BE SURE TO SET THE "DTV PORT" BACK TO AUTO.
- Select an analog Input as the signal source (INPUT button)
- Activate the Factory Option Menu (MENU-0-1-7-0)
- Use the “Adjust” keys to select “DTV Port” and use the “Enter” key to change the setting from “HD” to “AUTO”.
- Exit the Option Menu (Press MENU twice)
CONVERGENCE MODE FUNCTIONS
In the Convergence Mode there
are three main Functions (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.
- Use the VIDEO button to select an item.
- Use the ADJUST buttons to change data.
NOTE:
When Item “0 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.
- Use AUDIO button to select a Sub Function
- Use the VIDEO button to select an Adjustment Item.
- Use the ADJUST buttons to change data.
FINE CONV [PRESS-4]
Sub Functions
This mode is used to perform
Fine Raster Correction, and Fine Red and Blue Convergence Adjustments.
There are three Sub Adjustment
Functions, selected with the AUDIO button:
- FINE GREEN .... a Green Crosshatch is displayed, to make Fine Raster Corrections.
- FINE RED .... a White Crosshatch is displayed, to make Fine Red Convergence Adjustments.
- FINE BLUE .... a White Crosshatch is displayed, to make Fine Blue Convergence Adjustments.
CURSOR
In the Fine mode a Cursor is
added to the Crosshatch. The ENTER button toggles the Cursor between two modes:
- MOVE (blinking Cursor) use the ADJUST buttons to select any of 64 points on the Crosshatch.
- ADJUST (Non blinking Cursor) the ADJUST buttons adjust the active color at the current Cursor position, horizontally or vertically.
CURSOR COORDINATES
Specific intersections in the Crosshatch are assigned
vertical and horizontal coordinates. These are shown in the adjacent diagram.
The Cursor can only be moved to those positions that have coordinates assigned.
If the Cursor is at coordinates outside the screen area, the Cursor will not be
visible. Use the ADJUST buttons to move the Cursor to an intersection on the
screen.
DISPLAY
The on-screen display changes in the Fine mode,
as shown at the right. The display shows the vertical and horizontal data for
the current Cursor Position, and the horizontal and vertical coordinates for
that position.
SAVING DATA AND EXITING THE CONVERGENCE MODE
- Press MENU twice to exit the Convergence mode, data is automatically saved.
