FINE CONV (Press 4)
This mode is used to perform Fine Raster
Correction, and Fine Red and Blue Conver-
gence 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 dis-
played, to make Fine Red Convergence
Adjustments.
• FINE BLUE .... a White Crosshatch is
displayed, to make Fine Blue Convergence
Adjustments.
In the Fine mode a Cursor is added to the Cross-
hatch. See Figure 2-6. The ENTER button toggles
the Cursor between two modes:
• MOVE (blinking Cursor) .... use the AD-
JUST 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.
The on-screen display changes in the Fine mode, as
shown in Figure 2-7. The display shows the verti-
cal and horizontal data for the current Cursor Posi-
tion, and the horizontal and vertical coordinates for
that position.

Alignment Data Storage Locations
Data accessed in the Convergence Adjustment Mode
is stored in IC8D01 located on the PCB-Signal. Re-
placement PCB’s are supplied pre-aligned so that
only fine adjustments should be necessary after re-
placement. All other service alignment data is stored
on the PCB-E2P located on the DM assembly. When
replacing the DM assembly, retaining the original
PCB-E2P will minimize the need for any realign-
ment.
